GENEVA - A British-flagged oil tanker detained by Iran was not carrying any cargo, the head of the Ports and Maritime Organisation in Iran's southern Hormozgan province said on Saturday, according to the ISNA news agency.
The 23 crew members of the ship may be interviewed on technical matters, Allahmorad Afifipour added.
"If necessary, and at the request of judicial authorities, the crew may be summoned for technical and specialist interviews," ISNA quoted Afifipour as saying.
