At least one person has died and dozens of others have been injured after a flight from London to Singapore encountered severe turbulence.

A Singapore Airlines flight was forced to divert to Bangkok after a passenger was killed and 30 people were hurt, local media reported.

“We can confirm that there are injuries and one fatality on board the Boeing 777-300ER. There were a total of 211 passengers and 18 crew on board,” a spokesperson for the airline said.

“Singapore Airlines offers its deepest condolences to the family of the deceased.”

The Boeing 777 aircraft left the UK on Monday evening at 22.17 local time, flight tracking data showed.

The plane requested permission to make an emergency landing at Suvarnabhumi International Airport in Bangkok and touched down shortly before 4pm local time.

Several ambulances were seen on the tarmac preparing to treat passengers.
