Mutilated dolphins wash up on French coast in record numbers

Activists say 1,100 dolphins found since January - but real figure may be 10 times higher

A record number of dolphins have washed up on France's Atlantic coast in the last three months, many with devastating injures.

Environmental campaigners say 1,100 mutilated dolphins have been found since January, but the real figure could be 10 times higher as many bodies sink without trace. Activists warn the marine slaughter could threaten the extinction of the European dolphin population in the region.
