AFP, ANKARA: At least five migrants, including a baby, drowned as they tried to sail from Turkey to Greece, the Dogan news agency reported on Thursday.
The raft, which was transporting Afghan and Iranian migrants to the Greek island of Lesbos, foundered just 500 metres (550 yards) from the Turkish coast on Wednesday night.
Turkish coastguards managed to save nine of the migrants on board while two are still missing.
The fresh tragedy came as the European Union and Turkey are trying to firm up a proposed deal to end the worst migration crisis to hit the continent since World War II.
On Monday, Turkey proposed a deal that would see the EU resettle one Syrian refugee from camps in Turkey in exchange for every Syrian that Turkey takes from Greece, in a bid to reduce the incentive for people to board boats for Europe.
