A suspect has been arrested in New York over the death of a woman who was set on fire on a subway train in Brooklyn.

Police Commissioner Jessica Tisch described the incident on Sunday as "one of the most depraved crimes one person could possibly commit against another human being".

She said the woman was sleeping on a stationary F train to Brooklyn when she was approached by the suspect who used a lighter to ignite her clothing.

The victim died at the scene, she said, adding that the suspect had been taken into custody after he was detained on another subway train.

Police said the woman, who has not been named, was sleeping in a subway carriage at the Coney Island-Stillwell Avenue station in Brooklyn at about 07:30 local time (12:30 GMT) when a man approached her.

There was no interaction before the attack, police said, adding that they did not believe the two people knew each other.

The man got off the train as police officers on patrol in the station rushed to the fire.

"What they saw was a person standing inside the train car fully engulfed in flames," Ms Tisch said.

Police are still working to identify the victim and the motive for the attack.

The Saudi authorities, I am told, are currently working flat out to collate everything they have on the Magdeburg market suspect, Taleb al-Abdulmohsen, and to share it with Germany's ongoing investigation "in every way possible".

Inside the imposing sand coloured and fortress-like walls of the Saudi Ministry of Foreign Affairs in Riyadh there is a perhaps justifiable sense of pique.

The ministry previously warned the German government about al-Abdulmohsen's extremist views.

It sent four so-called "Notes Verbal", three of them to Germany's intelligence agencies and one to the foreign ministry in Berlin. There was, the Saudis say, no response.

Part of the explanation for this may lie in the fact that Taleb al-Abdulmohsen was granted asylum by Germany in 2016, one year after the former Chancellor Angela Merkel threw open her country's borders to let in more than a million migrants from the Middle East, and 10 years after al-Abdulmohsen had taken up residence in Germany.

Coming from a country where Islam is the only religion permitted to be practiced in public, al-Abdulmohsen was a very unusual citizen.

He had turned his back on Islam, making himself a heretic in the eyes of many.

Born in the Saudi date palm oasis town of Hofuf in 1974, little is known about his early life before he decided to leave Saudi Arabia and move to Europe aged 32.

Active on social media, on his Twitter (later X) account he labels himself as both a psychiatrist and founder of Saudi rights movement, together with the tag @SaudiExMuslims.

He founded a website aimed at helping Saudi women flee their country to Europe.

The Saudis say he was a people trafficker and the Ministry of Interior's investigators, the Mabaatheth, are said to have an extensive file on him.

There have been reports in recent years of dissident Saudis coming under hostile surveillance from Saudi government agents, in Canada, the US and in Germany.

There is no question that the German authorities, both federal and state, have made some serious errors of omission in the case of al-Abdulmohsen.

Whatever their reasons for not responding, as the Saudis claim, to the repeated warnings about his extremism, he was clearly a danger to his adopted host country.

There is also, separately, the failure to close off, or at least guard, the emergency access route to Magdeburg Alter Markt that allowed him to allegedly drive his BMW into the crowds.

German authorities have defended the market's layout and said an investigation into the suspect's past is ongoing.

But a complicating factor here is that Saudi Arabia, although considered a friend and ally of the West, has a poor human rights record.

Until June 2018 Saudi women were forbidden to drive and even those women who publicly called for that ban to be lifted before then have been persecuted and imprisoned.

Saudi Arabia's Crown Prince Mohammed bin Salman, still only in his 30s, just, is immensely popular in his own country.

While Western leaders largely distanced themselves from him after his alleged involvement in the grisly murder of the Saudi dissident Jamal Khashoggi in 2018, which the crown prince denies, at home his star is still in the ascendant.

Under his de-facto rule, Saudi public life has transformed for the better, with men and women allowed to associate freely, and cinemas reopening, along with big, spectacular sports and entertainment events, even gigs performed by Western artists like David Guetta and the Black Eyed Peas.

But there is a paradox here.

While Saudi public life has flourished there has been a simultaneous crackdown on anything that even hints at more political or religious freedom.

Harsh prison sentences of 10 years or more have been handed down for simple tweets.

No-one is permitted to even question the way the country is run.

It is against this backdrop that Germany appears to have dropped the ball with Taleb al-Abdulmohsen.

Slovakia's Prime Minister Robert Fico has made a surprise visit to Moscow for talks with Vladimir Putin - becoming only the third Western leader to meet the Russian leader since the full-scale invasion of Ukraine three years ago.

Fico - a vocal critic of the European Union's support for Kyiv in the war - said they discussed supplies of Russian gas to Slovakia - which his country relies on.

A deal with Russian gas giant Gazprom to transit energy through Ukraine to Slovakia is due to expire at the end of this year.

"Top EU officials were informed about my journey and its purpose... on Friday," Fico wrote on Facebook.

Fico said the meeting in Moscow was a reaction to Ukrainian President Volodymyr Zelensky telling EU leaders that Ukraine remains opposed to Russian gas being piped through its territory.

The Slovakian PM, who survived being shot earlier this year, also said he had a "long conversation" with Putin and the two "exchanged views on the military situation in Ukraine".

Both discussed "the possibilities of an early, peaceful end of the war" and mutual relations between Russia and Slovakia, Fico wrote on Facebook.

• Watch BBC challenge Putin on his 25 years in power in Russia

Slovakia and Hungary, which both depend on Russian gas, have raised concerns about the prospect of supplies being interrupted.

In October 2023, when Fico became prime minister again, he ended Slovakia's military aid to Ukraine.

But, he has insisted he wants to be a "good, friendly neighbour" to Ukraine.

Fico's meeting with Putin came as the leaders of Italy, Sweden, Greece and Finland met on Sunday for a security summit.

Speaking afterwards, Finland's Prime Minister Petteri Orpo said Russia was a "permanent and dangerous threat" to the EU.

He also stressed the need for increased defence spending and support for Ukraine.

Morrisons customers have been unable to get discounts on their shopping ahead of Christmas after a problem with the More loyalty card.

The supermarket has been advertising heavy discounts on Christmas dinner food, including vegetables, in the last week.

But social media users say their discounts are not working at the till, with one person posting a photo of an error message at the self-checkout, which reads: "We are really sorry some promotions and discounts are not working at this time."

The Morrisons website also appears to be down, with a "502 bad gateway" error message on some pages.

Morrisons has been contacted for comment.

Weather conditions are improving across the UK ahead of the final Christmas travel rush and last-minute shopping dash.

Almost all weather warnings which had been in place have now been lifted, after the weekend saw strong winds cause flight cancellations and widespread rail delays.

The disruption included a plane suffering an emergency incident at Belfast City Airport on Sunday evening, when its nose wheel appeared to break during landing in stormy conditions. The runway reopened on Monday morning.

The Met Office has forecast a "grey Christmas" with "extremely mild" temperatures for most in the coming days - ruling out any prospect of a white Christmas for the majority of the country.

It comes after parts of the UK were hit by chilly temperatures and 50-60mph winds on Saturday and Sunday - with the strongest gust recorded in South Uist on the Western Isles clocking in at 82mph.

But the travel picture looks far more straightforward for those making journeys today or on Tuesday.

While Heathrow Airport was forced to cancel around 100 flights on Sunday due to the conditions, a spokesperson said it was "business as usual" on Monday.

And National Rail was not reporting any widespread issues on Monday morning, though there were some isolated problems around Inverness, Portsmouth and Southsea.

Ferry customers are still being warned of ongoing disruption on some routes operating from Scotland and Northern Ireland.

A yellow weather warning for ice will remain in place for parts of northern Scotland until 10:00 GMT on Monday.

Temperatures are expected to improve "considerably" in the final run-up to Christmas Day, with sunshine forecast in some areas.

Met Office meteorologist Dan Stroud said "temperatures will be well above average" in England in Wales, though it will be overcast for many.

Christmas Eve is forecast to hit an average temperature of 12C or 13C, while Christmas Day is expected to be 11C or 12C.

"The usual average for this time of year is 7C or 8C so we'll be around double where we usually are," he added.

Hollywood stars America Ferrera, Amber Tamblyn and Alexis Bledel have publicly backed US actress Blake Lively after she filed a legal complaint against It Ends With Us co-star Justin Baldoni.

Ms Lively filed the legal complaint over the weekend against Mr Baldoni, alleging sexual harassment and a campaign to "destroy" her reputation.

Mr Baldoni's legal team told the BBC on Saturday that the allegations are "categorically false".

Ferrera, Tamblyn and Biedel, who starred with Lively in 2005 film The Sisterhood of the Traveling Pants, issued a joint statement on Instagram on Sunday saying they "stand with her in solidarity".

Coleen Hoover, the author of It Ends With Us, also showed her support, describing Ms Lively as "honest, kind, supportive and patient".

Lawyers for Ms Lively say the legal complaint follows a meeting earlier this year to address "repeated sexual harassment and other disturbing behaviour" by Baldoni, her co-star and a producer on the movie.

In their statement, Ferrera, Tamblyn and Biedel said: "As Blake's friends and sisters for over 20 years, we stand with her in solidarity as she fights back against the reported campaign waged to destroy her reputation.

"Throughout the filming of It Ends with Us, we saw her summon the courage to ask for a safe workplace for herself and colleagues on set, and we are appalled to read the evidence of a premeditated and vindictive effort that ensued to discredit her voice."

They added: "Most upsetting is the unabashed exploitation of domestic violence survivors' stories to silence a woman who asked for safety. The hypocrisy is astounding.

"We are struck by the reality that even if a woman is as strong, celebrated, and resourced as our friend Blake, she can face forceful retaliation for daring to ask for a safe working environment," the statement added.

"We are inspired by our sister's courage to stand up for herself and others."

Lawyers for Mr Baldoni said they hired a crisis manager because Ms Lively had threatened to derail the film unless her demands were met.

In the drama It Ends With Us, Ms Lively plays a woman who finds herself in a relationship with a charming but abusive boyfriend, played by Mr Baldoni.

In a post to her Instagram stories, Colleen Hoover, the author of the novel on which the film was based, also voiced her support: "@BlakeLively you have been nothing but honest, kind, supportive and patient since the day we met.

"Thank you for being exactly the human that you are.

"Never change. Never wilt."

She then linked to a New York Times article titled We Can Bury Anyone: Inside A Hollywood Smear Machine.

Hoover also re-posted the statement from Ferrara, Biedel and Tamblyn, adding: "This statement from these women and Blake's ability to refuse to sit down and 'be buried' has been nothing short of inspiring."

The meeting between Ms Lively and Mr Baldoni, together with others involved in the movie's production plus Ms Lively's actor husband Ryan Reynolds, took place on 4 January 2024, and it aimed to address "the hostile work environment" on set, according to Ms Lively's legal filing.

Mr Baldoni attended the meeting in his capacity as co-chairman and co-founder of the company that produced the film, Wayfarer Studios. He was also the film's director.

In the legal complaint, Ms Lively's lawyers allege that both Mr Baldoni and the Wayfarer chief executive officer, Jamey Heath, engaged in "inappropriate and unwelcome behaviour towards Ms Lively and others on the set of It Ends With Us".

In the filing to the California Civil Rights Department, a list of 30 demands relating to the pair's alleged misconduct was made at the meeting to ensure they could continue to produce the film.

Among them, Ms Lively requested that there be no more mention of Mr Baldoni and Mr Heath's previous "pornography addiction" to Ms Lively or to other crew members, no more descriptions of their own genitalia to Ms Lively, and "no more adding of sex scenes, oral sex, or on camera climaxing by BL [Blake Lively] outside the scope of the script BL approved when signing onto the project", says the complaint.

Ms Lively also demanded that Mr Baldoni stop saying he could speak to her dead father.

Ms Lively's legal team further accuse Mr Baldoni and Wayfarer Studios of leading a "multi-tiered plan" to wreck her reputation.

She alleges this was "the intended result of a carefully crafted, coordinated, and resourced retaliatory scheme to silence her, and others from speaking out about the hostile environment that Mr Baldoni and Mr Heath created".

Responding to the legal complaint, Mr Baldoni's lawyer, Bryan Freedman, said on Saturday: "It is shameful that Ms Lively and her representatives would make such serious and categorically false accusations against Mr Baldoni, Wayfarer Studios and its representatives."

Mr Freedman accused Ms Lively of making numerous demands and threats, including "threatening to not show up to set, threatening to not promote the film", which would end up "ultimately leading to its demise during release, if her demands were not met".

He alleged that Ms Lively's claims were "intentionally salacious with an intent to publicly hurt and rehash a narrative in the media".

In a statement via her attorneys to the BBC, Ms Lively said: "I hope that my legal action helps pull back the curtain on these sinister retaliatory tactics to harm people who speak up about misconduct and helps protect others who may be targeted."

She also denied that she or any of her representatives had planted or spread negative information about Mr Baldoni or Wayfarer.

The film was a box-office hit, although some critics said it romanticised domestic violence.

Chocolate maker Cadbury has been dropped from the list of royal warrants for the first time in 170 years.

The Birmingham-based chocolatier was awarded its first royal warrant as chocolate and cocoa manufacturers by Queen Victoria in 1854, but it has lost its royal endorsement under King Charles.

The King has granted royal warrants to 386 companies that previously held warrants from Queen Elizabeth II, including John Lewis, Heinz and Nestle.

Companies holding the Royal Warrant of Appointment, granted for up to five years, are recognised for providing goods or services to the monarchy.

Among the King's list of warrant holders are many firms selling food and drink, such as Moet and Chandon, Weetabix and chocolate makers Bendicks and Prestat Ltd.

Warrant holders are allowed to use the coat of arms of the royal they are associated with on packaging, as part of advertising or on stationery.

If you asked TV viewers to name a favourite double act, chances are the two stars of Vengeance Most Fowl would be close to the top of the list.

It's Wallace & Gromit's first major appearance in over a decade, and the first film not to feature the voice of Peter Sallis as the cheese-loving inventor.

"It has been quite emotional [doing this production] since we lost Peter, he was such an original, unique voice," says Nick Park of Sallis, who died in 2017 at the age of 96.

"So it's very hard for anyone to step into his shoes. But we have been blessed with a youngish actor whom we've known for many years who can do a fantastic Wallace impersonation.

"He's stepped in very kindly, and is just great. It's hard to tell them apart."

Take a bow, Ben Whitehead - the 47-year-old actor and voice artist says he feels honoured to be taking on the role. But also admits to feeling a degree of pressure.

"Enormous pressure!" he tells the BBC.

"Because it's a very popular character. I got to work with Peter [Sallis] a couple of times for [2005's] The Curse of the Were-Rabbit film.

"So yeah, there's a great deal of pressure with that. And I feel very grateful to Aardman for giving me so much time to build the character.

"You kind of have to do the 'hmm' and the 'hee-hee'," he continues - demonstrating some Wallace-isms that sound indistinguishable from Peter Sallies's Yorkshire tones.

"Definitely the elongation of the vowels like 'cheeeeese'!"

Why return now?

Fans have been clamouring for more from the plasticine pair for years. So why now?

"Whenever we've done talks around the world, the last question is always, 'When is the next Wallace & Gromit film?', explains Park. "The last time we did that I just came home burning with this idea that's been around for years."

The idea was - what if Wallace created a pre-programmed, voice-controlled smart Gnome.

Enter Norbot, but of course regular viewers of Wallace & Gromit will be unsurprised to learn that the inventor's well-intentioned idea, as usual, ends up causing mayhem.

This isn't the only familiar element to appear in this latest story.

This new adventure also features an old villain, the criminal mastermind Feathers McGraw, a chicken-impersonating-penguin whom Wallace & Gromit - mostly Gromit - defeated in 1993's The Wrong Trousers.

"Whenever we're out and about talking about the future of Wallace & Gromit, the single most asked question is 'when will Feathers be back?", says Merlin Crossingham, who directs Vengeance Most Fowl alongside Nick Park.

"Everybody loves a villain, it's often said your film is only as good as its villain, [so it] seemed a perfect opportunity to bring Feathers back for this story."

Wallace & Gromit were first introduced to audiences with 1989's A Grand Day Out. Since then their adventures have involved everything from malfunctioning clothing to mysterious were-rabbits.

"I think Wallace & Gromit have so many facets to their relationship," says Crossingham.

"They are best pals. They're kind of partners in crime, they're man and dog. And hopefully in the films, their stories, and their relationship everybody young and old relates to them.

"I truly think it's that relatability, not just of their simplicity of lifestyle from which madness erupts.

"But everybody somewhere in the stories connects with them on some level.

"And I think that what Nick has created, right back at the beginning with A Grand Day Out, has really struck a chord with people."

'Christmas day ratings battle'

The last time a new Wallace & Gromit adventure went out on Christmas Day was in 2008 with A Matter of Loaf and Death. It was day's most-watched show, with more than 16 million viewers tuning in.

It was also the most-watched show of the entire year.

While it's still possible that it could repeat that feat, it's up against some extremely tough competition.

"Bring it on, Gavin & Stacey!" jokes Crossingham, acknowledging the huge popularity of the Essex and Barry-based comedy, whose finale also goes out on Christmas Day.

However while Gavin & Stacey might be reaching its conclusion, this definitely isn't a finale for Wallace & Gromit.

"[It's] certainly not the end," says Nick Park. "I think there's plenty of bounce still in their bungee.

"We'll carry on. There's always ideas worth kicking about."

"Give us a minute though," Interjects Merlin. "They take a while to make!"

Wallace & Gromit: Vengeance Most Fowl is on BBC One at 18.10 on Christmas Day.

Children played on fairground rides designed by the world's greatest artists for a single summer before they disappeared for decades.

The attractions were part of the world's first art funfair - Luna Luna - dreamed up by little-known Austrian creative André Heller in the 1970s, featuring a carousel by Keith Haring, a Ferris wheel by Jean-Michel Basquiat and a David Hockney pavilion.

Visitors could wander Roy Lichtenstein's hall of mirrors and marvel at Salvador Dali's fun dome, sampling biscuits decorated by artist Gertie Frölich as actors dressed as nuns and flamingos milled about.

A successful attraction for months, plans for a grand European tour formed - but when they later fell through, an extensive legal battle ensued and the rides were shut down, disassembled and packed away, forgotten.

Until now.

Luna Luna is unwrapped

American entrepreneur Michael Goldberg stumbled across Luna Luna on an art blog. He'd never heard of it, despite some of the art world's biggest names contributing. Neither, to his surprise, had his friends in the industry.

"Everyone asked me what I was talking about," he said. "Something seemed a little odd."

'In love' with the fair, Goldberg wrote to Heller, introducing himself and proposing a new iteration of the Austrian's original dream.

The two slowly built a rapport and Heller revealed that the attractions had been stored in 44 shipping containers in Austin, Texas since their disassembly.

Opening in 1987, Luna Luna was a colourful success for three months. Its run was extended twice due to high demand, but while trying to fund a European tour, Heller fell into debt and sold the fair to an American foundation.

The foundation tried to back out of the deal - "buyers remorse", according to Goldberg - but eventually went through with it. For the duration of the years-long battle and the new ownership, however, the rides were kept in storage.

Decades since Luna Luna was packed away, Goldberg rallied a team of investors to buy what might be left of the exhibition from the foundation - sight unseen.

His key investor? Global rap star Drake, via his investment and entertainment business DreamCrew.

"The idea of restoring something so rich in cultural history outweighed the risks and for us, it wasn't about guarantees," Anthony Gonzales, CEO of DreamCrew, told the BBC.

The New York Times estimated they paid $100m (about £80m). The Guardian reported the sum at $1m. Goldberg did not disclose the final price to the BBC.

When he opened the first of the containers, Goldberg started to sweat. Luna Luna's original merchandise had been torn to shreds.

"Did I just lead a group to spend millions of dollars on a pile of dust artwork that essentially rotted away?" he wondered.

It was a sleepless night.

But the next day, as more paper was removed from a second container, the light caught a toffee-apple-red handlebar to Haring's carousel, then the white floorboards of Basquiat's Ferris wheel, which "could have been painted days ago". It was a moment of "instant relief", said Goldberg.

The return of Luna Luna

Unearthing the artwork wasn't the hardest part of Luna Luna's revival.

Brad Gooch, author of recent official Haring biography, Radiant: The Life and Line of Keith Haring, saw Luna Luna being reconstructed, describing the feat as "mind boggling."

"It was like a giant Lego with no instruction kit," he said.

A crew of artists, carnival technicians, curators and architects worked together to meticulously rebuild Luna Luna for two years before its grand reopening in LA this March.

Now, Luna Luna: Forgotten Fantasy has come to a Midtown Manhattan art and theatre complex, The Shed. The fair is on display alongside exhibits detailing its surreal curation process.

Alex Poots, creative co-founder of The Shed, described the journey as a "Raiders of the Lost Ark story", in reference to the film, praising Heller's ability to commission artists of such high calibre while finding a format appealing to "art lovers and yet to be art lovers."

"That is a holy grail kind of pursuit," he added.

Most of the original rides are now housed in a towering 17,000-square foot space. There, exhibition-goers can "marry" one another in Heller's Wedding Chapel - originally a form of protest art against anti-LGBTQ marriage laws of the 80s.

Hockney's Enchanted Tree Pavilion still smells faintly sweet, as if stampeding children once crushed fallen popcorn into its floor.

Goldberg's wish to incorporate "today's greatest artists" is fulfilled with a soundtrack by modern musicians André 3000, Jamie xx and Jockstrap echoing around the space.

Drake isn't involved day-to-day but, "he is passionate about Luna Luna and has provided his full support since the beginning," Gonzales said.

All the fun of the fair?

There's one big difference between 1987's Luna Luna and today's: Children aren't allowed on the rides.

Basquiat's Ferris Wheel and Kenny Scharf's swing ride are display-only. So too (thankfully) is Manfred Deix's Palace of the Winds in which performers originally farted into microphones.

Haring biographer Gooch doesn't think the artist would have approved of children just watching his carousel turn.

"I can't imagine he would allow it," he said. "He was pretty insistent about interactivity of children with art, and this was art that was specifically made for them."

Poots, who played a significant role in coordinating the interdisciplinary side of the exhibition said of the decision: "They're priceless works of art now."

But he champions the possibility of audiences becoming "part of this moving exhibition" through the "carnival-esque environment with performance artists with light, with sound".

It has been a career-long mission of Poots not "to create these silos for elites".

He added that ticket prices, criticised by some as being too high, are "pretty reasonable" as the show cost "millions and millions of dollars to install".

Among the families wandering around The Shed on Thanksgiving weekend were Raemy Suwatson and her 11-year-old daughter, who learned she wouldn't be able to go on the rides the morning of their visit.

Haring's carousel was her favourite. "I wanted to ride it" she said, then added "but it was also cool to watch".

The show is running from 20 November to 23 February, and will tour after it leaves The Shed. Ticket prices range from $44 for an adult to $241 for a Super Moon pass that allows buyers to skip lines. Children's tickets start at $25.
