African migrants 'drown'

Many people are feared dead after overcrowded boats carrying more than 400 African migrants capsized in the Mediterranean sea on their way to Europe, survivors say.

The migrants, who were travelling on four rickety boats, were mainly from Somalia, Ethiopia and Syria, Somalia's ambassador to Egypt has told the BBC Arabic. 

They left from Alexandria in Egypt hoping to reach Greece. 

Greek coastguards have so far managed to rescue 29 passengers, Somali media reports say.
