The killer of two British soldiers shot in Afghanistan on Saturday lured them to his side with a fake injury before firing on them, the BBC understands.

The troops, from 3rd Battalion The Yorkshire Regiment, died after the Afghan man - who was wearing a local police uniform - attacked them at a checkpoint in the south of Nahr-e Saraj, Helmand province.

It is not yet known whether the man was a real Afghan policeman.
