No survivors are expected after a passenger plane collided in mid air with a helicopter near Washington DC on Wednesday evening, officials in the US say. The plane was carrying 64 passengers and crew when it landed in the Potomac River after the collision, while the helicopter had three soldiers on board.

Officials say the conditions of the Potomac River are complicating recovery efforts of the bodies of the 67 presumed dead in a mid-air collision between American Airlines flight 5342 from Wichita and a military Black Hawk helicopter.
