A Dutch trawler was prevented from fishing in the waters off the coast of Mauritania on Thursday by environmental organisation Greenpeace, when activists tied a large buoy to the nets of the Dirk Diederik.

The action comes ahead of a European gathering of agriculture ministers next week to discuss reforms to fishing policy.
Greenpeace says the Dutch ship is over-fishing the seas of West Africa and leaving local fisherrmen with nothing to catch.
‘We want junior agriculture minister Henk Bleeker to recognise this social injustice and stand firm in Brussels for a fair and sustainable fleet,’ a Greenpeace spokesman said.
