A baby and a toddler were among seven people who died Friday when a migrant boat sank in the Aegean Sea, the Greek coastguard said, as rescuers searched for another four people missing.
The accident occurred near the tiny Greek island of Oinousses, located between the island of Chios and the Turkish coast.
Four children were rescued along with five men and three women, the coastguard said. Their nationalities were not immediately known.
Rescue crews initially recovered the bodies of a baby and a four-year-old child.
But after survivors told authorities that four people on the boat were still missing, the bodies of three more children and two women were found.
"The five bodies will be taken to Chios to determine if these are the people the survivors were talking about," a coastguard spokeswoman told AFP.
