Photos: A British Airways flight today makes an emergency landing

A British Airways flight to Verona made an emergency landing at London Heathrow today after passengers allegedly smelt burning and some crew members felt unwell.

Flight BA2596 to the Italian city returned to Heathrow Airport's Terminal Five after what the airline described as a 'technical issue' on the Airbus A320-232 plane. 

One witness tweeted a dramatic video of fire engines and other emergency vehicles at the airport after the plane returned to Heathrow having initially left at 7am.
