Twelve migrants thought to be from Syria and Afghanistan, including four children and a baby, drowned off the coast of Turkey as they tried to reach the Greek island of Lesbos, the Turkish coastguard said on Saturday. Reuters television footage showed bodies covered by plastic sheeting being brought ashore on a coastguard vessel near the Turkish town of Ayvacik, a few kilometres (miles) from the Greek island of Lesbos. A coastguard official said 23 people had been rescued, some by a Turkish fishing boat.
