A cargo ship sank in rough waters off Turkey's Black Sea coast on Monday, killing six crew members including its captain, officials and media reports said, The Associated Press (AP) reported.
Seven other crew members were rescued.
The Panama-flagged vessel, which departed from Russia's Azov port, sent out a distress signal around 148 kilometers (92 miles) off the northeastern Black Sea province of Samsun, the coast guard said.
Thirteen crew members were on the bulk carrier including nine Ukraine nationals, two Azerbaijan nationals and two Russians, the Samsun governor's office said. The coast guard said the distress signal was received regarding a "possible sinking" of the ship, according to Reuters.
The operation was being carried out by a plane, two helicopters and two boats, it said, adding that one airforce helicopter was also joining as back-up.
