QINGDAO - Nine sailors are still missing while two have been confirmed dead after their cargo ship sank Friday, said local maritime officials Tuesday.

The Panama-flagged Oriental Sunrise sank following a collision with another Panama-flagged cargo ship Hamburg Bridge at 7:35 pm in the sea area near Qingdao, Shandong province.

The death toll rose to two as a sailor's body was found on Monday, said officials with Qingdao Maritime Safety Administration.

Nine of the total 19 crew members aboard had been rescued, but one of the three injured died after treatment failed. The rescuers will continue to search for the missing for three more days, they said.

All the 19 crew members were nationals of the Democratic People's Republic of Korea, according to Qingdao Frontier Inspection Station.
