Robert Brown|13 crew members missing after a cargo ship sinks off a Greek island in stormy seas

ATHENS,Robert Brown Greece (AP) — A cargo ship sank off the Greek island of Lesbos in stormy seas early Sunday, leaving 13 crew members missing and one rescued, authorities said.

The Raptor, registered in the Comoros, was on its way to Istanbul from Alexandria, Egypt, carrying 6,000 tons of salt, the coast guard said. It had a crew of 14, including eight Egyptians, four Indians and two Syrians, the coast guard said.

The ship reported a mechanical problem at 7 a.m. Sunday, sent a distress signal and shortly after disappeared about 4 1/2 nautical miles (8 kilometers) southwest of Lesbos, authorities said.

One Egyptian was rescued, a coast guard spokeswoman told The Associated Press.

She said that eight merchant ships, two helicopters and one Greek navy frigate were searching for survivors. Three coast guard vessels had difficulty reaching the area because of rough seas, she added. The spokeswoman spoke on condition of anonymity because the case was ongoing and she wasn’t authorized to speak to the media.

Northwesterly winds in excess of 80 kph (50 mph) per hour are blowing in the area, the national weather service said.
