Over 200 migrants die trying to cross Mediterranean - UNHCR

Federico Fossi from the UNHCR said at least 203 people had died trying to cross the Mediterranean in the past few days.

He said that the number of deaths had been increasing, and that survivors had told him there was a fourth boat which had not yet been found and there are fears it has disappeared.

Rough weather has made the rescue mission difficult for teams from the Italian coast guard.
