Turkey's state-run news agency has reported that 14 refugees, including seven children, drowned when their wooden boat sank off the Turkish northern Aegean coast of Ayvacik on 11 November.
The Anadolu Agency said 27 others, including a pregnant women, were rescued by Turkish coast guards and are in good condition. Divers and helicopters are searching the waters for more possible victims. The report was confirmed by Dogan news agency.
Ayvacik is a main crossing point to the Greek island of Lesbos, which has seen a surge in the arrivals of refugees in the past few months.
European and African leaders are due to meet in Malta to discuss the migration crisis, with the EU hoping that pledges of cash to some of the world's poorest countries, including Eritrea, will help discourage others from making the journey.
