Greek authorities say six bodies have been recovered from a boat carrying migrants or refugees which sank off the northern coast of the island of Kos.

The coast guard said one survivor managed to reach the shore and raise the alarm. The survivor told authorities that roughly 10 people were believed to have been in the boat when it sank.

A coast guard patrol boat, a vessel from the European border control agency Frontex, a helicopter and a vessel from a Greek volunteer rescue group were searching the area for potential survivors. The bodies of three men, two women and an infant were recovered from the eastern Aegean sea.
