Iran's ambassador to the United Kingdom, Hamid Baeidinejad, warned the U.K. on Sunday against escalating tensions following Tehran's seizure of a British-flagged oil tanker, the Stena Impero, in the Strait of Hormuz on Friday. Baeidinejad said British political voices calling for action were "quite dangerous and unwise at a sensitive time in the region," adding that "Iran is firm and ready for different scenarios." In a recording of radio exchanges between a British Royal Navy frigate and Iranian armed forces vessels, the Iranian forces can be heard telling a ship, likely the Stena Impero, "if you obey you will be safe," while the British navy tells the ship that its passage must not be impeded. Tehran said the Stena Impero crew was in "good health."
