The US and Iran’s rival blockades of the Strait of Hormuz have become a “test of wills”, says BBC’s Chief International correspondent Lyse Doucet.
Earlier this month, US forces announced they would intercept or turn back vessels travelling to or from Iran’s coast.
Iran calls the blockade “piracy”, and its top negotiator, Mohammad Bagher Ghalibaf, has said reopening the strait is “not possible” while the US maintains its naval blockade.
Lyse Doucet is reporting from Tehran on condition that none of her material is used on the BBC’s Persian Service. These restrictions apply to all international media organisations operating in Iran.
