ISTANBUL, Sept 2 (Reuters) – Two Turkish-flagged commercial vessels collided off Istanbul in the Sea of Marmara ​on Wednesday and contact has ‌been lost with one of the ships, the Istanbul governor’s office said.

The Turkish-flagged Alsu, en route to the Aegean port of Aliaga, ‌and the ​Turkish-flagged Tugberk Imamoglu, en ⁠route to the ⁠Black Sea port of Karadenizeregli, collided off the Silivri district of Istanbul at around 3 a.m. (0000 GMT) ​on Wednesday, the governor’s office said in a statement.

Coast guard ships ⁠and helicopters were dispatched ⁠to the scene for ​search and rescue, and there was no ​visible damage on the Alsu, the ‌statement said. But authorities were unable to establish contact with the Tugberk Imamoglu and its 10 crew ⁠members.

According to data from the Istanbul Chamber of Maritime Commerce, the Tugberk Imamoglu, owned ⁠by ‌Zeybe Denizcilik, operates as a ⁠bulk carrier, while the ​Alsu, ‌owned by Ozpulathane Deniz Tasimaciligi, ​operates as ⁠a chemical tanker.

The search and rescue operation was still under way, the governor’s office statement said.
