Many people are feared to have drowned after the boat they were being transferred to by traffickers capsized in the Mediterranean, survivors say. The 41 survivors, migrants mainly from East Africa, spoke to the BBC from the southern Greek city of Kalamata, where they are being held after their rescue. They said up to 500 people had died, though there has been no official confirmation of the incident. Earlier, six bodies were found after a separate incident off the Libyan coast. Neither the Italian nor Greek coast guards have confirmed what would be one of the deadliest migrant boat disasters in recent years.
