At least 78 people have died and many more are feared missing after a fishing boat carrying refugees and migrants capsized and sank off the southern coast of Greece, in one of the worst such disasters this year.
The Greek coastguard said in a statement on Wednesday the vessel sank in international waters, 47 nautical miles (87km) southwest of Pylos, off the Peloponnese coast. The spot is close to one of the deepest areas of the Mediterranean.
The accident prompted an extensive rescue operation complicated by strong winds, the coastguard said, adding that about 100 people had been rescued so far. Six coastguard vessels, a navy frigate, a military transport and an air force helicopter, as well as several private vessels, were taking part in the search for those missing.
Four of the survivors were hospitalised in the port city of Kalamata with symptoms of hypothermia. Dozens of others were taken to sheltered areas in the city that were set up by the ambulance services and the United Nations Refugee Agency to receive dry clothes and medical attention.
None of those rescued had safety equipment such as life jackets, the coastguard said.
It was unclear how many passengers might still be in the water or trapped in the sunken vessel, but some initial reports suggested hundreds of people may have been on board.
