U.S. Hits Iranian Oil Hub as Trump Issues Ultimatum Over Hormuz Blockade

The conflict between the United States and Iran escalated sharply on April 7, 2026, as President Donald Trump issued a final ultimatum to Tehran. Trump warned that unless the Strait of Hormuz is reopened by 8 p.m. Eastern Time, the U.S. will destroy all remaining Iranian bridges and power plants. This threat followed fresh U.S. airstrikes on Kharg Island—which handles approximately 80% of Iran's crude oil exports—and coordinated Israeli strikes on railway hubs and transport infrastructure in major cities including Mashhad and Tabriz. In response, the Islamic Revolutionary Guard Corps (IRGC) announced a 'new phase' of military operations, pledging to utilize Fateh and Kheibar Shekan missiles to target Israeli and American interests. On the ground, Iranian civilians have reportedly begun forming human chains around power stations to deter further strikes. Tensions are further complicated by a diplomatic memo citing U.S. and Israeli intelligence which suggests that Iran's Supreme Leader, Mojtaba Khamenei, is currently incapacitated and receiving medical care in Qom. While President Trump confirmed that 'active' negotiations for a war-ending deal are ongoing, he expressed pessimism regarding Iranian compliance before the evening deadline. U.S. officials are also reportedly discussing the possibility of a ground occupation to break the maritime blockade. These developments occur amid a deteriorating humanitarian situation, with at least 18 civilians reported killed in recent strikes and nationwide transport networks largely paralyzed.
