Iran has rescued 29 of the 30 crew members of a UAE-flagged cargo ship that sank in the Gulf amid high winds and rough seas, state media report.
An operation was continuing to find the missing sailor, an emergency response official told Irna news agency.
Two rescue vessels and helicopters were dispatched after the Al Salmy 6 went down about 48km (30 miles) from the port of Assaluyeh on Thursday.
Winds were more than 70km/h (45mph) at the time, the Iranian official said.
The bad weather initially caused the ship to list at a precarious angle, Capt Nizar Qaddoura said, but within hours it was fully submerged.
The crew comprised nationals of Sudan, India, Pakistan, Uganda, Tanzania and Ethiopia, he added.
