A murder enquiry was launched in northern France today after a UK-bound migrant was shot seven times by suspected people smugglers.

The deceased – a man in his late teens or early 20s – is the latest victim of a surge of shootings around a camp at Loon-Plage, on the outskirts of Dunkirk.

'He was hit by seven bullets,' said an investigating source on Monday. 'The camp was full of people hoping to get to Britain, when he was confronted by gunmen.

'Around twenty bullets were fired in all, and seven entered the man's body. Emergency service workers attended the scene, but they could not save him.'

The Dunkirk prosecutor visited the crime scene, which on Monday was blocked off, and surrounded by armed police.
