world's biggest cruise ship 2023

The World’s Largest Cruise Ship Is Nearly 1,200 Feet Long

Scheduled to debut in January, the vessel can accommodate 5,600 guests and 2,350 crew members

Daily Correspondent

The world’s largest cruise ship is almost ready to set sail.

Royal Caribbean’s massive new ship, Icon of the Seas , passed its inaugural round of sea trials with flying colors, bringing it one step closer to hitting the open ocean with passengers, the cruise line  announced late last month. If all goes as planned, the record-breaking vessel will begin sailing in the Caribbean in January 2024.

Just how big is Icon of the Seas ? Really big. As Jalopnik ’s Ryan Erik King writes, it’s the size of five Titantics. More specifically, Icon of the Seas measures 1,198 feet long—nearly a quarter of a mile—and has a gross tonnage of 250,800. All that space means it can accommodate 5,600 guests and 2,350 crew members.

The cruise line is positioning the vessel as “the ultimate family vacation,” as CEO Michael Bayley told reporters earlier this year, per  CNN ’s Maureen O’Hare.

“When you step back and look at all the energy and time that has gone into creating this ship, it is mind-blowing,” he added.

The previous world’s largest cruise ship was also a Royal Caribbean vessel, Wonder of the Seas , which spanned 1,188 feet long and featured 18 decks.

Crews in Turku, Finland, began work on Icon of the Seas in 2021. Last month, the vessel sailed the open ocean for the first time, as staffers spent four days testing the main engines, hull, brakes, steering system and other components. They also measured noise and vibration levels. 

The vessel will undergo another round of sea trials later this year before officially launching in Miami early next year, according to Royal Caribbean. Icon of the Seas will primarily take cruisers to the islands of the eastern and western Caribbean on seven-night itineraries.

With progress on Icon of the Seas moving along, Royal Caribbean has already started building another large “icon class” ship. The cruise line expects that unnamed vessel to launch in 2025, per a  statement .

Icon of the Seas has 20 total decks, 7 swimming pools and 8 “neighborhoods,” or distinct areas with entertainment and dining. Another noteworthy feature is Category 6, which will be the largest waterpark at sea when Icon of the Seas sets sail.

The ship will be equipped with a special grooming robot that will clean the hull whenever it’s in port to help reduce drag and improve fuel efficiency by 3 to 4 percent, reports  TTG Media ’s Charlotte Cullinan.

Icon of the Seas will also be the first ship in the cruise line’s fleet to run on liquefied natural gas and  fuel cells , which are similar to batteries but do not need to be recharged. Water is the main byproduct of fuel cells—which combine oxygen and hydrogen to produce energy—which should help the ship reduce its greenhouse gas emissions.

Liquefied natural gas , meanwhile, is a controversial energy source that involves cooling natural gas to a liquid state to make it easier to transport. The liquid version is “actually worse than ordinary gas,” writes the  Natural Resources Defense Council . “The energy required to chill, ship and regasify the fossil fuel makes it far more carbon-intensive and increases the potential for leakage of dangerous methane,” according to the organization.

Royal Caribbean’s leaders say they view liquified natural gas as a “ transitional fue l,” and that they hope to continue to  reduce the environmental impact of their ships moving forward. 

"[Liquefied natural gas] is about 20-30 percent better for the environment [than heavy fuel oil], but it’s still not going to be the solution,” Bayley tells TTG Media . “We don’t know the answer, but the whole industry is working towards the answer.”

World's largest cruise ship that's 5 times larger than the Titanic set to make its debut

By Li Cohen

July 12, 2023 / 8:38 AM EDT / CBS News

The RMS Titanic was once considered the largest ship in the world before it met its demise in the Atlantic Ocean. Now, Royal Caribbean International has created a "first-of-its-kind" ship nearly five times that size that will soon make its debut. 

The cruise ship, called Icon of the Seas, is massive – measuring 1,198 feet long with 250,800 gross tonnage. Capable of carrying 7,600 guests and 2,350 crew members, the ship is equipped with 20 total decks, seven pools, and what Royal Caribbean describes as six "record-breaking" waterslides.

When the RMS Titanic embarked on its ill-fated maiden voyage in 1912, it measured more than 852 feet long with 46,329 gross tonnage. Icon of the Seas' tonnage is more than five times that amount. 

The new ship will soon be ready for use, starting in January 2024, the cruise company says, after hitting a milestone last month with the successful completion of its i nitial round of sea trials . During those trials, the ship was put on the open ocean for the first time. 

The ship is divided into eight primary areas : 

• The "AquaDome" sits atop the front of the ship, offering 220-degree views and a 55-foot waterfall
• The "Suite Neighborhood" with a Mediterranean restaurant and two-floor sundeck
• A five-deck-high open-air "Central Park" with living plant walls
• "Chill Island" with four pools and a swim-up bar
• "Thrill Island," featuring what the company says is the largest waterpark at sea, called "Category 6"
• An area dedicated to families called "Surfside"
• The "Royal Promenade" with ocean views
• "The Hideaway," which offers 180-degree views at the back of the ship and an infinity pool

Icon of the Seas first opened up for reservations in October of last year while the cruise industry was still recovering from the downturn it faced during the coronavirus pandemic.  At the time, prices started at $1,537 a person, but they have since increased by a few hundred dollars. 

Royal Caribbean now lists the cheapest ticket at $1,851 for an interior room on a seven-night cruise from Miami to the Western Caribbean in September 2024. The most expensive is substantially higher – $10,864 for a suite on the same cruise in March. The ship also offers a seven-day trip to the Eastern Caribbean.

And while many are excited about the chance to ride the ship to the Caribbean, calling it "stunning" and like a "scene from sci-fi movie" on social media, some others have expressed otherwise. 

"Every time I see a picture of the Icon of the Seas cruise ship I am filled with an intense dread ," one person said. 

" Infection of the Seas by Royal Caribbean," another person jested, seemingly alluding to past COVID outbreaks on cruise ships during the pandemic. 

But for Royal Caribbean, it's all about the excitement. The day it opened up tickets for the ship in October, Royal Caribbean said it had the single largest booking day in the company's 53-year history.

"The enthusiasm and excitement for Icon are undeniable in more ways than one," Michael Bayley, president and CEO of Royal Caribbean International, said in October . "The incredible response we have received from our loyal guests, vacationers new to cruising, crew members and travel partners continues to come in, and this is just the beginning. We can't wait to share more of what Icon has in store in the coming months."

The ‘Icon Of The Seas’ Will Soon Be The World’s Largest Cruise Ship — Here’s How Much It Costs To Get Aboard

The Icon of the Seas—what will be the world’s largest cruise ship to date with 20 decks, seven pools and a waterpark—is preparing for more trial runs after passing its first in June, six months ahead of its first scheduled voyage when it will carry almost 8,000 workers and passengers in January 2024.

The Icon of the Seas—what will be the world's largest cruise ship—will be able to carry nearly 8,000 ... [+] passengers and workers and is set to take its first voyage in January 2024.

Tickets for the first trips aboard the Icon of the Sea first opened in October 2022, started around $1,537 a person, and led to Royal Caribbean having its “single largest booking day in the company's 53-year history,” according to CBS .

Now, a ticket for one of the seven-day voyages to either the western or eastern Caribbean runs a bit pricier: the least expensive voyage, taking off in September 2024, costs about $1,851 a person for an interior room; most passenger prices for an interior rooms in other months run between $2,000 and $3,300.

For a seven-night trip to the eastern Caribbean, rooms with an exterior view start at $2,061 for a September voyage and go up to $4,119 for a March voyage; rooms with a balcony start at $2,249 in September and increase to $5,245 in March.

The ship will be nearly 1,200 feet long and is projected to weigh 250,800 tonnes; among its features are a 55-foot waterfall, a five-deck tall open-air Central Park with living plant walls, both a “chill island” and a “thrill island” offering different pool and waterpark features and an infinity pool, along with a number of restaurants and entertainment options.

The least expensive voyage scheduled for the Icon of the Seas, taking off in September 2024, costs ... [+] about $1,851 a person for an interior room; most passenger prices for an interior rooms in other months run between $2,000 and $3,300.

$10,864. That’s about how much it costs—per person—for a spot in the Sunset Suite aboard some voyages on the Icon of the Seas.

In June, the Icon of the Seas successfully completed its initial round of sea trials and sailed the ... [+] open ocean for the first time.

Key Background

Royal Caribbean already boasts having the world’s largest cruise ship—the Wonder of the Seas —so the Icon of the Seas will be breaking the cruise company’s own record. The Wonder of the Seas took its first voyage in 2022 and is only about a dozen feet shorter than the Icon. It can carry 7,084 people total, about 1,300 of whom are workers, and has 18 decks, two fewer than the Icon. Royal Caribbean started construction of the Icon in 2021 at a ship building facility in Finland, the same place the ship passed its first sea trials last month . The trials included four days of preliminary tests on the ship’s technologies and equipment and, according to a press release , the ship “successfully sailed the open ocean.”

The 20 Biggest Cruise Ships in the World in 2023

By: Author Carrie Ann Karstunen

Posted on Published: March 1, 2022  - Last updated: January 6, 2023

Cruise ships have been getting bigger—and adding lots of attractions that were unheard of just a few years ago. To help you pick which megaship is right for you, I’ve rounded up the 20 biggest cruise ships in the world in 2023.

Along with a ranking of the top 20 cruise ships by size , I’ve included important stats and unique features for each ship. If you’re considering sailing on one of the biggest cruise ships in the world, you’ll want to read this guide before you choose!

How do we determine the size of cruise ships for comparison?

Cruise ships can be measured by a variety of factors. You might assume that a ship’s size is determined by its length, weight, or even its passenger capacity.

But the size of a cruise ship is generally determined by gross tonnage —and (confusingly) that’s not a measurement of weight!

Gross tonnage, or GT, is a measure of the ship’s internal volume . To calculate GT, first a ship’s volume is calculated by measuring from keel to funnel to the outside of the hull framing. That number (in cubic meters) is then run through several mathematical formulas to determine GT. (I won’t go into all of that here, but if you’re interested the US Coast Guard has a simplified guide to measuring gross tonnage ).

The world’s 20 largest cruise ships in 2023

Currently, the top 20 biggest cruise ships have four sets of ties in the rankings, all between sister ships that share the same cruise line and class. So although we’ll start our list at #16, there are twenty ships in total!

Cruise fans will notice there are several new ships on the list this year. Have any of these newer ships bumped your favorites down in the rankings? Read on to find out!

16. (tie) MSC Seascape

• Cruise line: MSC
• Year built: 2022
• Gross tonnage: 170,412
• Length: 1112 ft / 339 m
• Max. beam: 135 ft / 41 m
• Staterooms: 2270
• Max. passengers: 5877
• Passenger decks: 15

Just making this year’s list of the world’s 20 largest cruise ships, MSC Seascape is tied for #16. The second Seaside EVO class ship launched by MSC Cruises in just over a year, Seascape features a glam New York City vibe.

The ship’s four-story Atrium is at the heart of the action on board, and boasts a sparkling staircase set with 10,000 Swarovski crystals—the perfect spot for a photo op on formal nights !

But MSC Seascape isn’t all glitz and glamour—the family-friendly ship offers 13 pools and water features and more than 140,000 square feet (13006 m²) of public outside space. Kids will love Pirates Cove Aquapark , a play space with slides, a rope bridge, and plenty of water sprayers and dumping buckets to beat the heat.

Seascape is also the first ship to feature the new thrill ride Robotron , a robotic virtual rollercoaster ride perched on the top deck.

Foodie guests on MSC Seascape will enjoy the ship’s eleven restaurants, including a massive Market Place Buffet and several specialty dining venues grouped together at Chef’s Court .

16. (tie) MSC Seashore

• Year built: 2020 (launched 2021)
• Max. beam: 134.5 ft / 41 m

Almost identical to her sister ship Seascape , MSC Seashore is tied for #16 on the list of the largest cruise ships. The first in the EVO subclass of MSC’s Seaside class ships, Seashore and her sister are larger than other ships in their class and offer expanded outdoor spaces.

As an EVO ship, MSC Seashore offers improved technology to increase efficiency and reduce her carbon footprint. The energy-efficient equipment includes an advanced wastewater purification system and Safe Air , a new sanitation system that eliminates viruses and bacteria.

Seashore was purpose-built for the American market, but still offers the European flair that MSC is famous for. Guests can enjoy a taste of Italy at the ship’s Venchi 1878 gelato bars , offering twenty flavors of the decadent frozen treat in flavors like tiramisù and stracciatella.

MSC Seashore also features a gorgeous aft infinity pool—one of the largest at sea—with luxurious submerged sunbeds. The spot is a tranquil adults-only oasis by day, but it comes alive in the evening as the setting for the always-popular Silent Disco .

15. (tie) MSC Bellissima

• Year built: 2019
• Gross tonnage: 171,598
• Length: 1,036.2 ft / 315.83 m
• Max. beam: 141 ft / 43 m
• Staterooms: 2,217
• Max. passengers: 5,686
• Passenger decks: 14

Tied for the fifteenth spot in the list of the world’s largest cruise ships, MSC’s Bellissima is as tall as thirteen double-decker buses!

Perfect for a family cruise, Bellissima offers a wealth of kids’ activities for children aged one through seventeen. Parents can track kids’ whereabouts on board via an RFID bracelet synced with MSC’s app. For adults who want to enjoy a leisurely meal, there’s the Happy Dinner program where the little ones are escorted to the kids club as soon as they finish eating!

MSC Bellissima is home to a thrilling Grand Canyon-themed waterpark with three waterslides—two racing tubes as well as a champagne bowl-style slide. The younger set will love the Aquaplay spray area, and guests of all ages can climb the Himalayan bridge, a rope course that crosses the ship high above the water.

Guests aboard Bellissima also have access to an electronic cruise assistant, similar to Siri or Alexa. A first in the cruise industry, Zoe —who speaks seven languages and adapts to each passenger’s preference—provides information and help booking shows, spa treatments, and shore excursions, as well as notifications of events and promotions.

15. (tie) MSC Meraviglia

• Year built: 2017
• Staterooms: 2,244
• Max. passengers: 5,655

When MSC’s Meraviglia entered service in 2017, she was the sixth-largest cruise ship in the world—but has since fallen to #15, tied with her newer sister ship Bellissima .

The namesake of the Meraviglia class of cruise ships, she was the first to offer an expanded dining experience with fourteen restaurants, including a whopping four complimentary main dining rooms. Celebrity chef Carlo Cracco was enlisted to improve the quality of the ship’s cuisine.

On Meraviglia entertainment options abound—the Broadway Theatre hosts six unique shows each cruise, along with the Carousel Lounge where you can experience Cirque du Soleil at sea. The crew also puts on an impressive amount of activities and events, so there’s always something to do on a sea day .

The ship’s Amusement Park has a full-size bowling alley, 4-D cinema, F1 simulators, an arcade, as well as a sportplex that becomes a disco spot for young cruisers in the evening.

14. (tie) MSC Virtuosa

• Year built: 2020
• Gross tonnage: 181,541
• Length: 1,087.4 ft / 331.43 m
• Max. beam: 160 ft / 50 m
• Staterooms: 2,421
• Max. passengers: 6,334

MSC’s ship Virtuosa , built in 2020, is one of the newer offerings by the Swiss-Italian cruise line and is tied for number fourteen on our list of the world’s biggest cruise ships.

Virtuosa offers five pools in total, plus a water park with three waterslides, so water babies of all ages can spread out and enjoy the fun. The pools can accommodate over a thousand guests at a time!

If relaxing with a cocktail is more your style, stop by and see Rob the bartender at Starship Club . He’s the first humanoid bartender at sea, and speaks six languages!

Cruisers can also wander the Galleria Virtuosa —the pretty indoor promenade with restaurants and shops features an arched ceiling with the longest LED dome at sea , presenting an ever-changing light display.

14. (tie) MSC Grandiosa

• Staterooms: 2,632
• Max. passengers: 6,761

Tied for number 14, Grandiosa was the first vessel in MSC’s Meraviglia-Plus class , later joined by her sister ship MSC Virtuosa .

With 200 more staterooms than previous MSC ships, Grandiosa has expanded the number of accessible cabins on board, and added groups of up to three connecting staterooms as well as new family balcony cabins. Some spacious family staterooms can sleep up to twelve!

Grandiosa also has some innovative environmental features, including systems to reduce nitrogen oxide emissions by 80%, and sulfur emissions by 97%. She has a fuel-efficient hull and can run on shore power when docked.

Fun fact: Grandiosa ‘s godmother is Italian screen legend and longtime MSC ambassador Sophia Loren. She actually holds that honor for most of MSC’s fleet!

13. Mardi Gras

• Cruise line: Carnival
• Gross tonnage: 181,808
• Length: 1,130 ft / 344 m
• Max. beam: 138 ft / 42 m

The 13th biggest cruise ship in the world is Carnival Cruise Line’s widely-anticipated Mardi Gras (currently the cruise line’s second-largest ship) which took her maiden voyage in July 2021.

Mardi Gras debuted several new concepts for Carnival, including three new dining venues. Big Chicken by Shaq serves up fried chicken and more, while quick-service Street Eats offers three food stations, each specializing in a different type of cuisine.

Emeril’s Bistro 1396 , created in partnership with celebrity chef Emeril Lagasse (Carnival’s new Chief Culinary Officer ), serves up New Orleans-style Creole dishes.

The Grand Central Atrium reinvented the central area of the ship, with a larger space featuring bars, cafés, and shops with aerial performances overhead.

Carnival Cruise Line’s newest ship Carnival Celebration launched in 2022 as the second member of the Excel class , joining her sister Mardi Gras . The new ship almost made the top 10 of the largest cruise ships, landing at number 11.

Celebration pays homage to her homeport of Miami with the 820 Biscayne zone, named after the cruise line’s first headquarters. The zone will feature the Deco Deli and 820 Bar , serving up Cuban sandwiches and tropical drinks.

Pizza fanatics will want to try the brand new Miami Slice , a free pizzeria that replaces the Pizza Pirate or Pizzeria del Capitano venues found on all other Carnival ships. The walk-up pizza joint features vibrant décor reminiscent of late-night eateries on Miami Beach’s Ocean Drive. 

Younger guests can check out Space Cruisers , a new program offered in partnership with the Kennedy Space Center. Kids age 2 to 11 will have the opportunity to try NASA-inspired activities tailored to their age group.

Celebration is the second ship in Carnival’s fleet to be completely powered by liquefied natural gas (LNG).

The new Body & Soul Spa features five ocean-view saunas, a sun terrace with three jacuzzis, and a tepidarium. Over 30 free exercise classes are offered each week in the Sport area, or train solo in the open-air gym.

• Cruise line: P&O
• Gross tonnage: 184,089
• Length: 1,130 ft / 344.5 m

8. (tie) Costa Toscana

• Cruise line: Costa
• Gross tonnage: 185,010
• Staterooms: 2,612

Italian line Costa Cruises’ newest ship, Costa Toscana , comes in at the eighth-largest cruise ship in the world. The Tuscan-inspired vessel features furnishings, fabrics, and accessories all made in Italy. Even the driftwood used to craft dining tables at Archipelago restaurant was harvested from the Italian shoreline by Guardians of the Coast .

Food is a major focus of the ship, with many of her 21 restaurants offering authentic local cuisine by chefs including Bruno Barbieri, Hélène Darroze, and Ángel León. Even the littlest cruisers have a special place to eat— Squok Restaurant is dedicated to families with kids.

If all the amazing food on board inspires you, be sure to check out Toscana ‘s Food LAB , where guests can learn to prepare their own culinary creations alongside the ship’s chefs.

8. (tie) Costa Smeralda

Tied for eighth place is Costa Smeralda , a favorite of sustainability-minded cruisers. Smeralda was the first in Costa’s fleet powered by liquefied natural gas (sister ship Toscana now also shares this feature), a fuel source that reduces the ship’s environmental impact.

Other eco-friendly features include LED lighting throughout the ship, an onboard desalinization plant that sustainably harvests onboard water directly from the sea, and systems that recover the engines’ heat to reduce energy use.

Costa Smeralda earned the coveted Green Plus notation from RINA, only awarded to the most environmentally friendly cruise ships.

• Cruise line: P&O Cruises
• Gross tonnage: 185,581
• Length: 1130 ft / 344.5 m
• Staterooms: 2614

P&O UK ‘s newest ship Arvia is also the cruise line’s largest, and debuts at #7 on the 2023 list of biggest cruise ships. An Excel-class ship like Iona , Arvia is similar but boasts some key differences.

• Max. beam: 154 ft / 47 m
• Staterooms: 2626
• Max. passengers: 6762

With the debut of MSC World Europa in December of 2022, MSC Cruises now has a whopping seven ships on the list of the top 20 biggest cruise ships in the world—the most of any cruise line!

The Geneva-based company has been working diligently to expand the fleet and MSC’s newest cruise ship is a whopper of a vessel.

The ship is an astounding 21 decks high (there’s a deck 22, but cruise superstition skips deck 13), four decks taller than the largest cruise ship in 2023. Sixteen of those decks are passenger-accessible.

Much like the megaships offered by Royal Caribbean, MSC World Europa is divided into several districts that contain similar offerings—a must-have on any gargantuan cruise ship. Guests can visit the adults-only Zen district for a bit of calm, or the Family district with ten kids’ facilities offering fun for little cruisers and their grownups.

Ranking among the top ships with the most water features at sea, World Europa offers six pools and 14 hot tubs , along with an aquapark featuring multiple waterslides.

MSC World Europa is also the line’s first LNG-powered cruise ship —and the biggest liquefied natural gas powered cruise ship in the world! This cleaner alternative to traditional marine fuel significantly reduces carbon, sulfur, and nitrogen oxide emissions.

Oasis of the Seas may be an older ship, but she doesn’t look like one! In 2019 she had a $165 million transformation that brought the ship up to date.

Entertainment abounds on this ship, from the splashy Aqua80 show in the AquaTheater to Music Hall , a live music venue with plenty of floor space for dancing. Or try one of the four onboard water slides including the ten-story-high Ultimate Abyss .

Built in 2018, Symphony of the Seas boasts some fun tech! Check out the Big Wonder , a seven-ton canopy lit with color-changing LEDs that cast a glow over the ship’s Solarium at night.

Enjoy a cocktail at Bionic Bar , where one of two robot bartenders can shake you up the perfect martini. But don’t worry, the ship’s 13 other bars and lounges are staffed by friendly humans.

Or play a lively game of glow-in-the-dark laser tag to battle for control of Planet Z —when the ship’s ice rink is temporarily transformed into an alien world, of course.

Travel | israel is quiet on next steps against iran — and on which partners helped shoot down missiles, things to do, travel | royal caribbean takes delivery of world’s largest cruise ship, icon of the seas.

There’s still two months to go before the first paying customers climb on board, but Royal Caribbean officially took possession Monday of the world’s largest cruise ship, Icon of the Seas.

Cruise line officials joined leadership with the Meyer Turku shipyard along with about 1,200 employees in Turku, Finland, for the handover ceremony of the 250,800-gross-ton, 1,198-foot-long, 20-deck vessel that had its first steel cut 31 months earlier.

“Delivering Icon of the Seas represents all that can be accomplished with strong partnerships and a commitment to delivering memorable vacations responsibly, and we thank Meyer Turku and an incredible village of skilled partners for joining us on this journey,” said Jason Liberty, president and CEO of Royal Caribbean Group, the parent company to Royal Caribbean International along with Celebrity Cruises and Silversea Cruises.

The ship has a distinct 363-ton glass-and-steel dome that was an engineering feat to get into place at the top of the vessel during construction. Called the AquaDome, it’s one of five new neighborhoods of eight total that mirror the approach taken on what is now Royal’s Oasis class of ships.

Icon of the Seas is about 15,000 gross tons larger than Wonder of the Seas, the most recent Oasis-class ship that currently sails out of Port Canaveral and is now bumped to No. 2 on the list of world’s largest cruise ships.

Icon actually has less passenger capacity based on double occupancy — 5,610 compared with Wonder’s 5,734. The size of the cabins and suites, though, gives Icon a maximum capacity of 7,600, which exceeds Wonder’s 7,084.

One more Oasis-class vessel, Utopia of the Seas, is due in 2024 and will also sail from Port Canaveral, while Icon has two sister ships in the works — the Star of the Seas due in 2025 and a yet-to-be-named ship in 2026. Icon of the Seas also becomes Royal’s first ship to use liquefied natural gas as fuel, a cleaner burning fuel that’s part of the cruise industry’s efforts to reduce emissions.

Royal Caribbean levels up entertainment for Florida-bound Icon of the Seas

“Welcoming Icon of the Seas to the Royal Caribbean family is a remarkable accomplishment years in the making for thousands of innovators, engineers, architects and designers,” said Royal Caribbean International President and CEO Michael Bayley. “Seven years ago, we had an ambitious idea to create the first vacation truly made for every type of family and adventurer; now, it’s in our hands, and in this final stretch, we’ll bring it all to life for the biggest debut in our history in January 2024.”

Icon of the Seas is set to sail from Finland to a shipyard in Cadiz, Spain, where it will continue to get some finishing touches ahead of a planned Dec. 23 transatlantic cross for its arrival in Miami. It will then sail a series of preview voyages before its first revenue cruise on Jan. 27 as it begins year-round alternating seven-night Eastern and Western Caribbean itineraries.

Royal Caribbean cooks up new venues for world’s largest cruise ship Icon of the Seas

Royal Caribbean has a tradition of building the world’s largest cruise ships. Even before the debut of Oasis of the Seas in 2009, it first achieved the record-holding title in 1987 with the Sovereign of the Seas, which was less than 1/3 the size of Icon with just over 73,000 gross tons. It held onto that title until 1990 before it jumped around ships for nearly a decade among Norwegian, Carnival and Princess.

It came back to Royal Caribbean with the debut of Voyager of the Seas in 1999 coming in at more than 137,000 gross tons, a little more than half the size of Icon of the Seas.

Sister ships Explorer of the Seas and Navigator of the Seas then inherited the title before Cunard Line’s Queen Mary 2 took it over from 2003-2006. Then Royal’s Freedom of the Seas took the title back with its more than 154,000 gross tons. Freedom’s sister ship Liberty of the Seas then held if from 2007 until Oasis of the Seas’ debut two years later.

Since then, the title has passed on to each Oasis-class vessel with incremental size increases starting with Allure of the Seas in 2010, Harmony of the Seas in 2016, Symphony of the Seas in 2018 and Wonder of the Seas in 2022.

I sailed on Royal Caribbean's 2 largest cruise ships. They were shockingly similar for the $1,000 difference

• Royal Caribbean operates many of the cruise industry's biggest ships.
• Icon of the Seas  launched in January, dethroning its predecessor, Wonder of the Seas, as the world's largest.
• Here's how the two mega-ships compare in size, neighborhoods, amenities, dining, cabins, and costs.

Icon of the Seas, Royal Caribbean's new mega-cruise ship darling, was deemed a success before it was even built.

In January, the highly anticipated vessel — complete with more than 40 bars and restaurants, a six-slide waterpark, and a waterfall — set sail, dethroning its less than two-year-old precursor, the Wonder of the Seas , as the world's largest cruise ship.

Before its debut, Michael Bayley, the president and CEO of Royal Caribbean International, had already repeatedly called Icon its "best-selling product" yet. The company experienced its largest booking day ever when reservations opened for Icon of the Seas more than a year before its launch, it said

Despite all of this fanfare, you might be surprised by how similar it is to its predecessor.

I've sailed on both ships. Let's see how Icon and Wonder compare in six categories: size, neighborhoods, amenities, dining, cabins, and costs.

Both ships stunt the size of their competitors.

Wonder of the Seas debuted in 2022 as the then-world's largest cruise liner, measuring 235,600 gross-tons, 1,188 feet-long, and 18 decks-tall. The ship can accommodate up to 9,288 people, including 2,204 crew.

Icon of the Seas is, comparatively, 13,063 gross-tons heavier, eight feet longer, and two decks taller. It can sail up to 9,950 people, including 2,350 crew, although it's 52 feet less wide than its predecessor.

Both vessels feel more like amusement parks than traditional cruise ships.

Royal Caribbean invited me on complimentary, non-revenue sailings on both ships: two nights on Wonder in late 2022 and three nights on Icon in January.

I spent most of my time lost, overwhelmed, and exhausted.

It's no surprise both ships are operating weeklong itineraries this year. Any less, and you might not have time to experience all the activities and restaurants on your list.

Like other Royal Caribbean ships, Wonder and Icon have eight 'neighborhoods' that serve separate purposes.

The new ship shares three of Wonder of the Seas' neighborhoods : Central Park, Royal Promenade, and Suite.

Icon's other five — Thrill Island , Surfside, Hideaway, Chill Island, and AquaDome — are a first for the cruise line.

Many of the ships' amenities overlap, but in differing quantities.

Wonder has three waterslides. Icon has a six-slide waterpark complete with rafting and racing options.

Both have increasingly popular cruise amenities like decks-long dry slides, mini-golf courses, rock climbing walls, and playgrounds.

But instead of Wonder of the Seas' zipline , Icon of the Seas has Crown's Edge, a thrilling agility course with a small zipline that leaves travelers dangling 154 feet above the ocean.

Wonder’s Boardwalk neighborhood was my go-to.

Boardwalk delivered exactly as it had promised: an open-air space grounded by wood-planked floors, a hot dog stand, a sweets store, and kitschy, colorful decor.

Icon of the Seas' Surfside , designed for families with young children, felt like its closest dupe.

Both neighborhoods had a carousel, an outdoor playground, and family-friendly dining. But Surfside was more toddler-friendly, as suggested by the children's water play area and nighttime story readings.

On to entertainment: Both mega-ships have ice skating performances and exciting multi-disciplinary shows at the AquaTheater.

But travelers who enjoy musicals at sea will want to stick to Icon.

Unlike its predecessor, the new ship shows a rendition of Broadway hit "The Wizard of Oz" — Munchkins, a puppet Toto, and a 16-piece live band included.

The layout of Icon's amenities were better than its cousin.

Some of Wonder of the Seas' enticing outdoor amenities — like the surf simulator, zipline, and mini-golf course — are clustered on the deck above and away from the pools and water slides.

This layout might be difficult for parents with children who bounce from one activity to the next. Wouldn't it be easier to have all of these outdoor extras near each other, or at least on the same deck, for parental supervision purposes?

This is where Icon of the Seas excelled: All its exciting open-air activities were adjacent.

The rows of pools flowed perfectly into Thrill Island's waterpark , rock climbing walls, mini-golf course, and Crown's Edge.

The best part? The adult-only Hideaway — which flexes an infinity pool club with a DJ — is right behind Thrill Island, creating a clear separation between parents and their children without being too far from each other.

'Free' options like the buffet and build-your-own tacos and burritos bar are available on both ships.

But you won't find the larger vessel's five-stall food hall or mini-golf-adjacent finger food stand on Wonder.

As expected, Icon of the Seas has more dining options than its predecessor, although there are some overlaps.

Wonder of the Seas has 11 bars and 21 dining venues (9 complimentary and 12 upcharged).

Icon of the Seas has eight more bars, four more complimentary restaurants, and three more specialty dining choices.

Nor will you find the new ship’s plush $200-a-person Empire Supper Club on any other cruise liner.

The multi-course dinner, paired with cocktails and live music, stunts the cost of either vessel's other dinner options.

But if you love Johnny Rockets, you’ll be disappointed by Icon of the Seas.

Restaurants like the popular burger chain and Southern comfort-inspired Mason Jar are only on Wonder of the Seas. Fine by me: My fried chicken at Mason Jar was as dry as a desert.

The younger ship doesn't have Wonder's robot bartender-armed bar either. It does, however, have new watering holes with dueling pianos and live jazz.

Surprisingly, Wonder of the Seas has 65 more cabins than its new cousin.

But several of Icon's 28 stateroom categories are a first for the cruise line.

This includes the new family infinite balcony cabin, which has a small bunk bed nook for children.

Royal Caribbean assigned me an ocean-view balcony stateroom on both ships.

My Wonder of the Seas' cabin was 20 square-feet smaller than the one on Icon. But my bathroom on the latter was so tiny, I accidentally elbowed the walls at almost every turn.

Sailing on the world's largest cruise ship doesn't mean you'll have the world's largest cabin after all.

Wonder and Icon are both operating seven-night roundtrip itineraries from Florida to the Caribbean.

In 2024, Wonder of the Seas is scheduled for year-round sailings from Port Canaveral to the Caribbean and Royal Caribbean's private island, Perfect Day at CocoCay , starting at $700 per person.

Icon of the Seas is spending its first year in service operating nearly identical itineraries but from Miami instead. The cheapest 2024 option is $1,786 per person.

That's a difference of more than $125 per person per day.

"Bookings and pricing for Icon of the Seas can only be described as 'iconic,'" Naftali Holtz, the CFO of Royal Caribbean Group, told analysts in February.

Icon of the Seas’ name speaks for itself.

If your family is looking for a jam-packed kid-friendly cruise with enough amenities to stay entertained for a week, both ships are a great option.

But if you're a seasoned mega-ship-cruiser looking to experience something new, Icon of the Seas is your best bet.

They may be similar, but no other behemoth cruise liner has a waterpark for children and a pool club for adults just dozens of feet from each other.

All of the heaviest cruise ships in the world were built within the last 20 years, although the majority – six of the ten – were built within the last five years.

So, here are the top ten biggest cruise ships in the world, by gross tonnage.

Middle East crisis — explained

The conflict between Israel and Palestinians — and other groups in the Middle East — goes back decades. These stories provide context for current developments and the history that led up to them.

Israel shoots down missiles and drones after Iran launches unprecedented attack

Israeli Iron Dome air defense systems launch to intercept missiles fired from Iran, in central Israel on Sunday.

Booms and air raid sirens sounded across Israel and the occupied West Bank early Sunday morning, after Iran launched dozens of drones and missiles toward Israel, in an attack that marked a major escalation of conflict in the Middle East.

In Washington, President Joe Biden said U.S. forces had helped Israel down "nearly all" the drones and missiles, and pledged to convene allies to develop a unified response.

Israeli military spokesperson Rear Adm. Daniel Hagari said Iran fired more than 300 projectiles at Israel overnight, 99% of which were shot down, the "vast majority". Officials reported minor damage to a military base in southern Israel and one injury to a 10-year-old child, who was reported to be in critical condition.

"We will do everything we need, everything, to defend the state of Israel," Hagari said. He added that some of the launches came from Iraq and Yemen.

How Iran and Israel became archenemies

The Israeli War Cabinet planned to meet at lunchtime. In a statement Sunday, Secretary of State Antony Blinken said the U.S. does "not seek escalation" of the conflict.

G7 leaders are meeting on Sunday afternoon to coordinate on a diplomatic response to Iran's attack, and engage with officials across the Middle East. The United Nations Security Council is is also set to meet, after Israel requested the council condemn Iran's attack, and designate the Iranian Revolutionary Guard Corps a terrorist organization.

Iran had vowed to retaliate after an airstrike on an Iranian consulate in Syria earlier this month killed seven Iranian military officials . It is the first time that Iran has launched an attack on Israel from Iranian soil, Israeli officials said.

U.S. forces in the region were active in shooting down drones, a U.S. defense official said. And interceptions by Israel's anti-missile defense system lit up the skies over populous areas including Tel Aviv and Jerusalem.

The Israeli emergency medical service Magen David Adom reported that a 10-year-old child had been struck in the head by shrapnel in the area of Arad, a town near the southwestern edge of the Dead Sea. Paramedics also treated about 20 people who suffered from anxiety or minor injuries experienced while seeking shelter, the service said.

Saturday's attack, which was first announced by Israeli officials around 4 p.m. ET, was staged in waves and took hours to reach Israel, officials said.

In a statement broadcast on Iranian state television, Iran's Islamic Revolutionary Guard Corps described the attack as a "large-scale military operation" against multiple targets inside Israel.

In a post on the social media site X, Iran's permanent mission to the United Nations wrote that the attack was a direct response to the strike on the consulate and that "the matter can be deemed concluded."

Following Tehran's overnight drone and missile attack on Sunday, Iran warned Israel of a larger attack on its territory should it retaliate, adding that Washington has been warned not to back Israeli military action.

"Our response will be much larger than tonight's military action if Israel retaliates against Iran," armed forces chief of staff Major General Mohammad Bagheri told state TV, adding that Tehran warned Washington that any backing of Israeli retaliation would result in U.S. bases being targeted.

The U.S. military was directly involved in the response, a senior U.S. defense official said. "In accordance with our ironclad commitment to Israel's security, U.S. forces in the region continue to shoot down Iranian-launched drones targeting Israel. Our forces remain postured to provide additional defensive support and to protect U.S. forces operating in the region," the official said.

Israelis were urged to take shelter

This video grab from AFPTV taken on Sunday shows explosions lighting up Jerusalem's sky during an Iranian attack on Israel.

Officials in Israel had explicitly urged residents of Nevatim, Dimona and Eilat — three cities in Israel's Negev desert region — and people in the northern occupied Golan Heights to take shelter. A major Israeli air base is located near Nevatim, and an Israeli nuclear research facility is located in Dimona.

Airspace over Iraq, Jordan and Lebanon was closed late Saturday, while some airlines announced the cancellation of some flights and the re-routing of others due to the attacks. Israel and Jordan reopened their airspace on Sunday morning.

Hezbollah, the Lebanon-based militant group, said that it had staged its own attack by launching dozens of rockets toward an Israeli military base in the Golan early Sunday.

In a Saturday night address to Israelis, Israeli Prime Minister Benjamin Netanyahu said that his country was ready for "any scenario, both defensively and offensively."

"We have determined a clear principle: Whoever harms us, we will harm them. We will defend ourselves against any threat and will do so level-headedly and with determination," Netanyahu said.

After striking throughout the Middle East, Iran's proxies now become the targets

President Biden monitored the attack from the Situation Room alongside top defense and diplomatic officials. In anticipation of the attack, he had cut short a trip to Delaware in order to return to the White House.

Afterward, he spoke with Netanyahu and said Israel had "demonstrated a remarkable capacity to defend against and defeat even unprecedented attacks – sending a clear message to its foes that they cannot effectively threaten the security of Israel."

"At my direction, to support the defense of Israel, the U.S. military moved aircraft and ballistic missile defense destroyers to the region over the course of the past week" the president said. "Thanks to these deployments and the extraordinary skill of our servicemembers, we helped Israel take down nearly all of the incoming drones and missiles."

Iran blames Israel for an earlier attack on its consulate

Iran's supreme leader Ayatollah Ali Khamenei speaks on March 1 in Tehran, Iran. Iran vowed to respond after an attack on an Iranian consulate in Syria.

The attack on Israel comes four days after Iran's leader Ayatollah Ali Khamenei vowed retaliation for an April 1 strike on an Iranian consulate in the Syrian capital of Damascus. Iran said the strike killed seven members of Iran's Revolutionary Guard Corps, including two generals, and it blamed Israel for the attack. Israel has neither confirmed nor denied being behind the attack, though the Pentagon said Israel was responsible.

By Saturday, as anticipation had grown over a possible retaliation, Israeli officials warned residents living in communities near Gaza and the Lebanon border to limit the size of gatherings and to work indoors or within reach of a shelter. Schools across Israel were closed through Monday.

Iranian officials accuse Israel of a deadly attack on Iran's consulate in Syria

U.S. defense officials told NPR Saturday that the U.S. military had moved assets around the region in anticipation of an attack, including aircraft, and had shored up defensive positions for forces in the region. The top U.S. military commander in the Middle East, Gen. Michael Kurilla, arrived in Israel Thursday to coordinate with the Israeli military.

In a post on Telegram on Sunday, Hamas expressed support for Iran's attack, calling it a "natural right" and a deserved response to the Israeli strike on an Iranian diplomatic compound in Syria this month. The militant group called on Arab and Islamic nations to continue their backing in its fight against Israel, according to the Washington Post.

Also on Sunday, a statement by Israel's intelligence agency Mossad announced that Hamas had rejected the latest hostage deal outline, which would have led to a six week pause in fighting between Israel and Hamas. They blamed the lapse in negotiations directly on Hamas leader Yahya Sinwar.

The attack is a large escalation of hostilities in the region

The strike and retaliation represent an escalation of conflict in the region that many officials worldwide had expressed worry about ever since the outbreak of war between Israel and the Gaza-based militant group Hamas on Oct. 7, the day Hamas led an attack on Israel that left some 1,200 people dead.

United Nations Secretary-General António Guterres said on Saturday that he condemned Iran's attack and was "deeply alarmed about the very real danger of a devastating region-wide escalation."

Egypt's foreign affairs ministry called Iran's attack a "dangerous escalation" and in a Saturday night statement urged "the exercise of the utmost restraint to spare the region and its people further factors of instability and tension." Jordan's Prime Minister said on Sunday any escalation in the region would lead to "dangerous paths", while United Arab Emirates foreign ministry called for the exercise of the utmost restraint to avoid dangerous repercussions.

Iran has long supplied Hamas with funds and weapons . The White House has not directly linked Iran to the Oct. 7 attack.

In the six months since Oct. 7, Israel has bombarded Gaza and conducted a devastating ground invasion that has left much of the territory in ruins and more than 33,000 Palestinians dead, according to Palestinian health officials.

The last time Iran launched a similar attack was in 2020 , when it fired ballistic missiles at the Ain al-Asad Air Base in Iraq, wounding dozens of U.S. troops, in retaliation for the killing of Iranian general Qassem Soleimani by a U.S. drone strike in Baghdad.

Russia-Ukraine war latest: Putin 'may launch all-out bid to seize second city' - as Western officials fear major Russian advance

Russia has launched fresh strikes on critical infrastructure - with Kyiv residents told to cut energy consumption every night for the rest of 2024. Meanwhile, Western officials reportedly fear a major Russian advance - amid concerns Vladimir Putin could launch an attempt to seize Kharkiv.

Sunday 14 April 2024 14:42, UK

• Ukrainian defences 'at risk of collapse' as officials fear major Russian advance - and all-out assault to seize second city
• Russia hits critical infrastructure in overnight missile strikes
• Putin mocks peace conference
• The big picture : Everything you need to know about the war this week
• Your questions answered: Is it too late to save Ukraine?

While we haven't been able to bring you live updates today, we have been keeping an eye on what's been happening in the Ukraine conflict. 

Here's a quick round-up of the key updates so far: 

• Two people were killed by Ukrainian strikes on the Russian-held parts of Kherson, the Moscow-installed regional governor said;
• Russia's defence ministry said its air defence systems destroyed 10 Ukraine-launched drones over the Krasnodar region in southern Russia and five drones over the Black Sea overnight; 
• Ukraine similarly claimed to have downed 10 Russian drones;
• The death toll in Zaporizhzhia from yesterday's attack, which Russia blames on Ukraine, rose to 16;
• President Zelenskyy condemned last night's attack by Iran on Israel.

At least 10 people, including children, have been killed by shelling in a Russian-occupied town in Ukraine's southern Zaporizhzhia region, a local Kremlin-installed official said.

A Ukrainian rocket also struck a machine-building plant in Russian-occupied Luhansk in eastern Ukraine, injuring three civilians, according to Moscow-based official Vladimir Rogov.

Meanwhile, Russia has claimed to have taken a village in Ukraine's Donetsk region. 

Russia's defence ministry said the capturing of Pervomaiske had improved its tactical position on the frontline. 

Ukraine's army chief has also warned the situation on the eastern front had deteriorated in recent days, with Moscow's forces intensifying its armoured assaults. 

Colonel General Oleksandr Syrskyi said battles were still raging for control of a village west of the devastated Bakhmut - an area that has seen some of the bloodiest fighting throughout the war.

We'll be back tomorrow morning with more updates on the war in Ukraine.

Two Biden administration officials have revealed the extent of China's involvement in Russia's war on Ukraine.

The officials spoke to Reuters news agency and said China has massively increased its sales to Russia of machine tools, microelectronics and other technology to Moscow.

These items are important because Russia is using them to make tanks, aircraft, missiles and other weapons for the war.

They also said:

• About 90% of Russia's microelectronics came from China
• Nearly 70% of Russia's approximately $900m in machine tool imports in the last quarter of last year came from China
• Chinese and Russian entities have been working together to make drones in Russia
• China is helping Russia improve its satellite and other space-based capabilities for use in the war. This could increase the threat Russia poses across Europe

US President Joe Biden has previously raised concerns with Chinese President Xi Jinping about Beijing's indirect involvement in the war.

US Treasury Secretary Janet Yellen returned this week from a visit to Beijing and said she had warned China that the Biden administration was prepared to sanction Chinese banks, companies and Beijing's leadership if they helped Russia's military in the war.

She has already been given the go-ahead from Mr Biden to sanction financial institutions that help Russia's military-industrial complex.

US Secretary of State Antony Blinken is due to travel to China for talks next month.

Russia, increasingly isolated economically and diplomatically, has become more reliant on China in recent months.

One official said Chinese materials are helping Moscow undertake its "most ambitious defence expansion since the Soviet era and on a faster timeline than we believed possible early on in this conflict".

"Our view is that one of the most game-changing moves available to us at this time to support Ukraine is to persuade the PRC (China) to stop helping Russia reconstitute its military industrial base. Russia would struggle to sustain its war effort without PRC input," the official said. 

Chinese Embassy spokesperson Liu Pengyu told Reuters that Beijing has not provided weapons to any party and that it is "not a producer of or party involved in the Ukraine crisis".

"We urge the US side to refrain from disparaging and scapegoating the normal relationship between China and Russia."

If Russia defeats Ukraine it will be a "turning point in history", former UK prime minister Boris Johnson says.

Writing in the Daily Mail, he criticised Western countries for not providing Ukraine with the weapons it needs to defeat Russia.

"Every week in which we fail to do the obvious — and give the Ukrainians the weapons they need — is a week in which Putin gets closer to his disgusting ambition, to torture a European country to death.

"Every day the pressure on the Ukrainians is growing — and yet the solution is within our grasp."

Mr Johnson, who visited Ukraine a number of times during his premiership, said: "A defeat for Ukraine would usher in a new era of fear in the whole Euro-Atlantic area, as Putin continues his drive to rebuild the Soviet empire: from the Baltics to Georgia to Moldova to Central Asia to the Arctic.

"It will be a terrifying moment for the people of Taiwan and the clearest possible signal to China that the West has lost the willpower to protect democracy.

"It will be a turning point in history, the moment when the West finally loses its post-war hegemony, the moment when borders everywhere are suddenly up for grabs and aggression is seen to pay — and all because of a failure to stand up for Ukraine."

Mr Johnson warned the world is "on a knife-edge, with a real risk that Western democracies are about to be humiliated, and autocracies emboldened around the world — because of our lassitude, our pathetic refusal to do what is necessary".

He said Ukraine is so short of shells that its troops sometimes have to wait under Russian bombardment because they can't fire back.

The shortage of air defences means Kharkiv, the second-largest city, is "in danger of being turned into another Mariupol", he added.

Ukrainians were able to intercept 90% of incoming strikes, he said, but now "we are starving them, for reasons I do not understand, of the protective shields they need".

Mr Johnson called on the US Congress to approve a $60bn military aid package earmarked for Ukraine and on the Germans to supply Taurus missiles.

The West - including Britain - needs to "snap out of our sleep-walk", he said, adding: "The simplest and most cost-effective way to defend freedom is to invest now in the defence of Ukraine."

Rescue workers in Ukraine have saved five puppies from under the debris of a destroyed building.

The non-residential building was on fire in the north-eastern city of Sumy, close to the border with Russia.

A video from the State Emergency Service of Ukraine showed the firefighters cuddling the squealing puppies and rinsing them off with water.

In a post of the emergency service's Telegram channel, officials said the "little ones" were not injured.

"This rescue story reminds us of the importance of human compassion and the willingness to help everyone, regardless of the circumstances," they added.

Ex-armed forces minister James Heappey has told Sky's defence and security editor Deborah Haynes the UK should consider sending its forces to Ukraine to train troops.  

On the Sky News Daily, host Tom Cheshire talks to her and Sky's military analyst Professor Michael Clarke about the interview with Mr Heappey, who stepped down from his role last month.  

They assess the bleak situation in Ukraine and why the conflict is at a critical stage. They also discuss how prepared the UK would be if it faced a war in the near future.

A former Ukrainian secret service employee has been injured in Moscow after a device under his car exploded.

Vasily Prozorov suffered leg injuries that are not considered life threatening after the device detonated as he tried to start his car, Radio Free Europe cited Russian media as saying.

According to RFE, Mr Prozorov worked for Ukraine's SBU until 2018.

The following year, he told media in Moscow that he had collaborated with Russia "for ideological reasons" from April 2014 until he left the SBU.

These photos show the damage to a thermal power plant in Kharkiv, eastern Ukraine.

A massive missile and drone attack destroyed and damaged a number of power plants across Ukraine overnight, part of a renewed Russian campaign targeting energy infrastructure.

The Trypilska plant, which was the biggest energy supplier for the Kyiv, Cherkasy and Zhytomyr regions, was struck numerous times, destroying the transformer, turbines and generators.

Vladimir Putin said the attacks were a response to Ukrainian strikes that targeted Russian oil refineries.

In Kharkiv, there were at least 10 other strikes on energy infrastructure, resulting in damage like that seen in these photos.

Ukraine's foreign minister Dmytro Kuleba said more than 200,000 people in the region were without power.

Herman Halushchenko, its energy minister, said it was a "large scale, enormous, missile attack that affected our energy sector very badly".

More details have emerged about American Russell Bentley, who is missing in the Russian-controlled Donetsk region in eastern Ukraine.

Online news outlet Mash said he disappeared on 8 April after a district in the city of Donetsk was shelled by Ukrainian forces.

Mash cited his wife as saying he had gone to see if anyone needed help but had not returned.

Mr Bentley joined pro-Russian fighters in eastern Ukraine in 2014.

According to Russian news outlet RIA, he later swapped his gun for journalism and worked with state-run news outlet Sputnik.

In a 2022 Rolling Stone interview, he came across as a conspiracy theorist (he said the collapse of the World Trade Towers was a "pre-planned controlled demolition") and a fan of dictators (he described war crimes-accused former Libyan leader Muammar Gadhafi as "one of the greatest").

He became a citizen of the Donetsk People's Republic in 2017 and a citizen of Russia in 2020, said the interview, which was headlined The Bizarre Story Of How A Hardcore Texas Leftist Became A Frontline Putin Propagandist.

In words similar to those of Russia's president Vladimir Putin, Mr Bentley described the Ukrainian military as "genuine mass-murdering Nazis", also claiming their ranks were swelled by "thousands of ISIS cannibals" - claims that have been widely dismissed by commentators.
