A British man has walked away from the wreckage of the Air India crash that killed 241 people in an extraordinary tale of survival.

Vishwashkumar Ramesh was in seat 11A on the London-bound Boeing 787 flight when it crashed shortly after takeoff in Ahmedabad, western India.

Mr Ramesh's brother, Nayan Kumar Ramesh, told BBC News that Vishwashkumar "has no idea how he survived" and escaped the plane as the only survivor.

Air India said all other passengers and crew were killed, including 169 Indian nationals and 52 Britons.

Nayan told the BBC "it feels great seeing him [Vishwashkumar] doing well" but he was worried about his other brother Ajay, who was also onboard.

"We were all in shock as soon as we heard what happened, just utter shock. Speechless," he said.

"He [Vishwashkumar] himself has no idea how he survived, how he got out the plane.

"When he called us he was just more worried about my other brother, like 'Find Ajay, find Ajay.' That's all he cares about at the moment."

A relative called Jay told the PA news agency: "He's got some injuries on his face. He was painted in blood. He's doing well I think. It's a big shock."

Video shared on social media showed Mr Ramesh walking towards an ambulance, with smoke billowing in the background.

He was later seen in a hospital bed meeting Indian interior minister Amit Shah.

Dr Dhaval Gameti, who treated Mr Ramesh, said: "He was disoriented, with multiple injuries all over his body. But he seems to be out of danger."

Indian media said he shared his boarding pass, which showed his name and seat number.

The businessman, who was born in India and has lived in the UK since 2003, has a wife and four-year-old son.

The plane crashed into accommodation used by trainee doctors less than a minute after take-off in Ahmedabad in the state of Gujarat. It is not clear how many people on the ground died and the cause of the crash is still unknown.

Three Britons thought to have died on the flight have been named by Gloucester Muslim Society as Akeel Nanabawa, his wife Hannaa Vorajee and their daughter Sara.

"They touched lots of people and they will be missed by lots of people," Imam Abdullah Samad.

Couple Fiongal and Jamie Greenlaw-Meek, who run a spiritual wellness centre in London, are also thought to have been on the flight.

They laughed and joked in an Instagram video as they told of their "10-hour flight back to England".

Their firm, the Wellness Foundry, has been approached for comment.

Also on the plane were Javed and his wife Mariam Syed, from West London, alongside their two young children.

Ammaarah Taju, the granddaughter of a couple from Blackburn who were onboard the flight, said she was in shock and disbelief.

Adam Taju, 72, and his wife, Hasina, 70, were flying back from Ahmedabad's International Airport with their 51-year-old son-in-law, Altafhusen Patel, who lives in London with his wife.

In a statement from the King, he said he and his wife were "desperately shocked by the terrible events in Ahmedabad this morning".

"Our special prayers and deepest possible sympathy are with the families and friends of all those affected by this appallingly tragic incident across so many nations, as they await news of their loved ones," the statement added.

Prime Minister Sir Keir Starmer said his thoughts were with the families who were going to be "absolutely devastated by this awful news", while his Indian counterpart Narendra Modi said it was "heartbreaking beyond words".

UK Foreign Secretary David Lammy has arranged crisis teams in India and the UK, and has chaired a meeting of the government's emergency committee in response to the crash.

London Gatwick Airport confirmed that a reception centre for relatives of passengers was being set up where information would be provided, and that it was liaising closely with Air India.

It said on X: "British nationals who require consular assistance or have concerns about friends or family should call 0207 008 5000."

Air India flight AI171 left Ahmedabad's Sardar Vallabhbhai Patel International Airport at 13:39 local time (08:09 GMT), Air India said.

It was scheduled to land at London Gatwick at 18:25 BST.

One video verified by the BBC shows the plane descending before a large explosion as it hits the ground.
