The wooden boat capsized in high waves two miles off the Bademli coast in the Aegean, the private Dogan news agency reported, adding that another 14 migrants were missing.
The Turkish coastguard were hunting for the missing and divers were rushed to the scene after a tip-off that more refugees could be stuck in the deck, Dogan said.
