BBC News: About 400 migrants are feared drowned after their boat capsized off Libya, survivors have told Save the Children.

The Italian coast guard rescued 144 people from the boat on Monday and launched an air and sea search operation in hopes of saving others.

Hundreds more migrants rescued from boats in the Mediterranean are due to arrive in Sicily during the day.

More than 8,000 migrants have been picked up since Friday, and more boats are heading for the Italian coast.
