A boat carrying dozens of migrants capsized off Turkey's shores in the Aegean Sea, leaving 12 dead, the state-run Anadolu news agency reported.
The coast guard managed to rescue 28 people, among them women and children, the report said. Many of them were Syrian refugees.
Turkey hosts around 2 million Syrians and is a major gateway point for migrants trying to reach the European Union, often taking dangerous boat journeys to nearby Greece.
The European Union agreed last year to give Turkey 3.2 billion dollars to help combat illegal immigration, though the deal remains to be finalized.
