LONDON/DUBAI (Reuters) - An Iranian Revolutionary Guards commander threatened on Friday to seize a British ship in retaliation for the capture of an Iranian supertanker by Royal Marines in Gibraltar.
"If Britain does not release the Iranian oil tanker, it is the authorities' duty to seize a British oil tanker," Mohsen Rezai said on Twitter.
