UK Foreign Secretary Philip Hammond has said that "at least" three British citizens were onboard the Germanwings flight which crashed in the French Alps yesterday.
All 150 passengers and crew onboard the flight, which was travelling between Barcelona and Dusseldorf, are believed to have died in the incident which happened around 11am local time on Tuesday.
"We currently believe that three British people have been killed in this tragedy, but we cannot rule out the possibility that there are further British people involved," said Hammond.
"The level of information on the flight manifest doesn't allow us to rule out that possibility until we've completed some further checks.
"We are also in contact with the French, German and Spanish authorities, and once we have a clearer picture, we will make a further announcement"
Rescue workers have already retrieved one of the aircraft’s black box recorders, and are searching for the second recorder. The cockpit voice recorder was damaged in the crash but officials believe they can still gather information from it.
The leaders of Germany, Spain and France are all expected to visit the crash site later today – 67 passengers onboard were believed to be German nationals and more than 40 were from Spain.
Germanwings is part of the Lufthansa Group and primarily operates on short-haul routes around Europe.
Yesterday, Airbus released details of the crashed A320 aircraft.
