A collision between a speedboat carrying migrants and a Greek coast guard patrol vessel off the eastern Aegean island of Chios late Tuesday has killed at last 14 people, the coast guard said.

Fifteen migrants died in the Aegean Sea off Greece on Tuesday after their boat collided with a coast guard vessel off the island of Chios, the coast guard said.

A statement issued late on Tuesday blamed "smugglers" for "failing to comply with the [Hellenic] Coast Guard's visual and audible signals" to turn their boat around.
