A Libyan Navy spokesman has said 36 people have been rescued after a vessel carrying 250 people went down near Tajoura, east of Tripoli.
"There are so many dead bodies floating in the sea," the spokesman told reporters.
Reports are also emerging of another sinking, in which up to 500 people may have drowned last week off the coast of Malta.
The International Organization for Migration (IOM) quoted two Palestinian survivors as telling them that the traffickers deliberately sank the boat after an argument on board.
This is the fourth boat carrying migrants from Libya to have sunk in the past month.
