Three more bodies found by authorities after Greek shipwreck

Men's remains recovered in open water on sixth day of search since boat carrying up to 750 people sank

Greek authorities have retrieved a further three bodies in open waters near the spot where a fishing trawler packed with Europe-bound migrants sank last week.

The bodies - all men - were recovered late on Monday, the sixth day of a search and rescue operation in the area, raising the official death toll to 81.
