One person was killed and several others injured on a Singapore Airlines flight from London that experienced severe turbulence on Tuesday.
The Boeing 777-300ER carrying a total of 211 passengers and 18 crew bound for Singapore was diverted to Bangkok and landed at 08:00 GMT.
“Singapore Airlines offers its deepest condolences to the family of the deceased,” the airline said in a statement.
The airline also said it was working with Thai authorities to provide medical assistance to passengers on flight SQ 321 and would send a team to Bangkok to provide any additional assistance needed.
According to the bbcThai authorities have sent ambulances and emergency teams to Bangkok's Suvarnabhumi airport.
Details about the nature of the turbulence are still unclear.
Flights typically experience some turbulence regularly and it's usually not entirely worrying, but serious incidents like this are rare.
Sometimes turbulence can be predicted (and pilots have been known to radio each other to give each other advance warning), but it can also come out of nowhere.
Although it is a meteorological phenomenon, turbulence can occur anywhere and under any conditions.
