Turkey-flagged general cargo ship Bilal Bal sank at about seven nautical miles off the coast of Istanbul and ten crew members have been reported missing.
The 1974-built ship sank shortly after it sent out a distress signal in the morning hours of November 1 while it was in the Black Sea.
Officials said that the cause of the sinking is still unknown and the vessel is currently resting at a depth of some 88 meters.
Turkish Coast Guard informed that a search and rescue operation is currently underway for the missing crew members who are all Turkish nationality.
The coast guard deployed three vessels, one helicopter and a plane for the mission.
At the time of the incident, the 2,999 dwt vessel was carrying a cargo of cast iron from the country’s Bursa province to Zonguldak, Reuters cited local media.
