On the Stena Impero, he said the vessel is currently at the Bandar Shahid Bahonar, which is a short distance from Iran's Bandar Abbas port.
"Vessel 'Stena Impero' currently stationed at Bandar Shahid Bahonar, a short distance from Bandar Abbas port. Our Ambassador has conveyed all crew are on board and safe. Just spoke to our Ambassador in Tehran. Confirmed that consular access to 18 Indian nationals on board 'Stena Impero' was sought on 20 July," Muraleedharan stated.
Britain and Iran have been locked in a bitter row ever since super tanker GraceA1 carrying Iranian crude oil was seized by the British marines in the Strait of Gibraltar on suspicion of violating the EU sanctions against Syria.
In retaliation, Iran on Friday seized the British-flagged Stena Impero, which has Indians, Russians, Latvians and Filipinos working as crew.
