STOCKHOLM: Seven crew members of a Swedish-owned tanker seized by Iran in July will be released, the chief executive of Stena Bulk that owns the tanker said Wednesday. Stena Bulk CEO Erik Hanell said that Iranian authorities said that the crew members will be released but the date of release is still unknown. The British-flagged tanker has a total crew of 23 on board. Iran’s Islamic Revolutionary Guard Corps seized control of the Stena Impero on July 19 as it was navigating through an international passage in the middle of the Strait of Hormuz, a narrow chokepoint at the entrance of the Gulf. The ship has since been held offshore near Iran’s southern port of Bandar Abbas. Iranian officials have given varying reasons for its seizure and continued detention. But Iranian authorities have denied the seizure of the Stena Impero was a tit-for-tat move after British commandos seized an Iranian oil tanker on July 4 as it passed through Gibraltar’s waters, under suspicion it was breaking EU sanctions on oil deliveries to Syria.
