TEHRAN, Iran -- An Iranian news agency says a diving support ship has sunk in the Persian Gulf and 13 people, including eight foreigners, are missing.
The semiofficial ISNA news agency said Friday that the vessel, the Koosha 1, went down some 15 miles off Iran's coast Thursday afternoon.
It says the 13 people still missing include six divers who were trapped underwater in a diving chamber with a limited oxygen supply. They were helping install offshore oil platforms.
The agency says some 60 people have been rescued, and the foreign workers on the ship were Ukrainian and Indian.
Calls to Dubai-based Dulam International that is leading the rescue operation were not immediately returned.
The vessel sank after leaving the offshore oil platforms near the South Pars gas field.
