The US Air Force has begun to remove the bodies of four American airmen who died in a helicopter crash in north Norfolk.

British and American investigators are trying to establish what caused the Pave Hawk aircraft to come down during a training exercise on Tuesday night.

Chief Superintendent Bob Scully from Norfolk police said moving the bodies was "a cautious process".
