A fishing boat carrying dozens of migrants capsized and sank off the southern coast of Greece early on Wednesday, killing at least 32 people.
A large search and rescue operation was launched following the night-time incident some 45 miles (75km) south-west of the Peloponnese region.
Authorities said 104 people have been rescued so far, including four who were taken to hospital with symptoms of hypothermia. It was unclear how many passengers remained missing at sea after the 32 bodies were recovered, the Greek coast guard said.
