At least 15 dead as 2 migrant boats sink in Greek waters

At least 15 people have died after two boats carrying migrants sank in Greek waters, and rescuers were looking for dozens still missing, authorities said early Thursday.

The coast guard said 15 bodies had been recovered near the eastern island of Lesbos after a dinghy carrying about 40 people sank. Five people were rescued and three had been located on a rocky outcrop near the site of the sinking.

A second rescue effort was launched several hundred kilometresto the west, near the island of Kythera, where a sailboat carrying about 100 migrants sank late Wednesday.

Officials said 30 people had been rescued after that boat hit rocks off the village port of Diakofti on the east of the island. Winds in the area were up to 70 km/h.

"We could see the boat smashing against the rocks and people climbing up those rocks to try and save themselves. It was an unbelievable sight," Martha Stathaki, a local resident told The Associated Press.

"All the residents here went down to the harbour to try and help."

Fire service rescuers lowered ropes to help migrants climb up cliffs on the seafront. Local officials said a school in the area would be opened to provide shelter for the rescued. Navy divers were also expected to arrive Thursday.

Most migrants reaching Greece travel from neighbouring Turkey, but smugglers have changed routes in recent months in an effort to avoid heavily patrolled waters around Greek islands near the Turkish coastline.

Kythera is some 400 kilometreswest of Turkey and on a route often used by smugglers to bypass Greece and head directly to Italy.
