The United States and Iran traded military strikes after Washington on Friday accused Tehran of attacking a cargo ship, jeopardising a fragile ceasefire as diplomats struggle to contain the Middle East war. US Central Command said the American strikes, against Iranian missile and drone storage sites and coastal radar positions, were a response to “unwarranted aggression against commercial shipping by Iranian forces” that “clearly violated the ceasefire”. It described the operation as “a powerful response to yesterday’s attack on a commercial ship that was transiting the Strait of Hormuz”.
