The US and Iran have agreed to "stand down" following an exchange of strikes over the past few days, media reports cite a US official as saying. It comes after several attacks in and around the Strait of Hormuz, with both nations accusing each other of violating their ceasefire. The US official told the BBC's US partner CBS News on Sunday that vessels would be able to move through the Gulf waterway "freely", and that talks on a deal to permanently end the war would continue.
