Six children have drowned as two migrant boats carrying them from Turkey to Greece sank in the Aegean Sea, Turkish media say.
The first boat carrying about 55 mainly Syrian and Afghan migrants sank off the Turkish town of Ayvacik.
The second was carrying about 20 people when it sank off Bodrum.
Turkey has become a major transit point for people fleeing conflicts in Syria, Iraq and Afghanistan, and hoping to reach northern Europe.
Hundreds of thousands of migrants and refugees have entered the European Union since August, heading up through the Western Balkans.
