The U.S. president had warned that Iranian power plants would be destroyed if Tehran failed to “fully open” the Strait of Hormuz to all shipping within 48 hours, setting a deadline of around 7:44 p.m. EDT (2344 GMT) on Monday. His comments sparked threats of retaliation from Iran’s Revolutionary Guards, which said they would attack Israel’s power plants and those supplying U.S. bases across the Gulf region if Trump followed through with his threat to “obliterate” Iran’s power network.
