Two investigations are underway in Greece into allegations that the country's coastguard caused a boat carrying Afghan migrants to sink while towing it back to Turkey.
Some of the survivors claim the Hellenic Coastguard would not allow them to try to save 11 women and children who were left in the water after their boat capsized.
But the coastguard said it was forced to cut the tow line to save its own vessel from capsizing when all of the other boat's occupants suddenly moved to one side.
