Only one passenger has survived after a plane bound for Gatwick Airport crashed shortly after take-off in India.
The Air India aircraft departed from Ahmedabad airport in Gujarat state with more than 240 people on board.
Here's what we know so far about the events.
What happened?
Air India's flight 171, from Ahmedabad to Gatwick, took off at 1.38pm local time, according to the airline.
The Boeing 787-8 Dreamliner aircraft crashed in a residential area called Meghani Nagar minutes after taking off, the director general of the directorate of civil aviation, Faiz Ahmed Kidwai said.
A video of the crash circulating online showed the aircraft flying over a residential area before disappearing behind trees, followed by a huge explosion and large plumes of black smoke.
Images of the aftermath of the crash showed parts of the plane embedded into B.J Medical College as firefighters continued to tackle the smoke.
Pieces of the aircraft's landing gear, fuselage and tail could all be seen protruding from the building.
Who was on board?
The plane was carrying 230 passengers and 12 crew members, according to Air India.
The airline said 169 passengers were Indian nationals, 53 were British, one was Canadian and seven were Portuguese.
How many casualties have there been?
Police said the death toll stood at 260 following the Air India crash.
The death toll includes people on the ground.
Officials initially said it appeared as though all those on board died but one British man has survived.
Air India confirmed that 241 out of 242 people on board the flight were killed in the crash.
Forty-year-old British man Vishwash Kumar Ramesh survived the crash, saying: "Thirty seconds after take-off, there was a loud noise and then the plane crashed. It all happened so quickly."
Divyansh Singh, vice president of the Federation of All India Medical Association, said at least five medical students had been killed and around 50 were injured after the plane collided with the college.

What have witnesses described?
A nearby resident present at the scene described "many bodies lying on the ground" after the incident.
He wore a surgical mask during the translated interview that aired on BBC News as smoke appeared to billow behind him and people in military uniform and masks could be seen walking around.
The man, who was not named, told the reporter: "I was sitting at home, there was a loud noise, it felt like an earthquake.
"I came out and saw smoke, I didn't realise it was a plane crash, then I came here and I found out and I saw the crashed plane - there were many bodies lying on the ground."
What caused the crash?
It is not yet known what the cause of the crash was.
A former pilot said the crash may have been caused by a bird strike.
Saurabh Bhatnagar told Indian news TV channel New Delhi Television the incident appears to involve "multiple bird hits".
He said: "It looks, prima facie, like a case of multiple bird hits wherein both the engines have lost power."
Bird strikes are defined as a collision between a bird and an aircraft which is in flight, taking off or landing.
A large flock of birds entering an aircraft engine can cause power loss.
Paul Williams, professor of atmospheric science at the University of Reading, said the weather conditions at the airport when the crash happened "appear to have been very good" as it was a "dry and sunny day" in Ahmedabad with "good visibility" and "no bad weather in the vicinity".
"There is no indication at this stage that turbulence or other weather conditions were a factor in the crash," he said.
