Meanwhile , British Foreign Secretary Philip Hammond has described the crash as a 'tragic incident' and sent his condolences to those who have lost family or friends.
He said: 'I don’t want to speculate on numbers of British nationals involved until we have completed our checks on all the passenger information.
'However, based on the information available to us, it is sadly likely that there were some British nationals on board the flight. We are providing consular assistance and will give further help as more information becomes available.'
He added Britain was working closely with the French, German and Spanish authorities, and the airline to establish the facts.
