A helicopter evacuating injured people from China's earthquake zone has crashed in fog with 14 people on board.
An operation to look for survivors is under way alongside the wider rescue and relief effort in Sichuan province. Troops battling to stop a lake formed in the quake from flooding the city of Mianyang are reported to have finished digging a diversion canal.
