The United States Central Command (CENTCOM) says it has launched a “heavy wave of strikes against Iran”, following Iranian missile attacks on US forces a day earlier. The strikes came hours after US President Donald Trump promised to hit Iran, “very hard”, after it targeted a base in Jordan where US troops are stationed. Reporting from Tehran, Al Jazeera’s Resul Serdar said these latest strikes are “concentrated in Iran’s southern provinces, particularly those along the Gulf and the Strait of Hormuz”, similar to the US attacks during a recent 13-day campaign. A deputy security minister in Khuzestan province told Iran’s state broadcaster IRIB that US forces targeted “some locations in Abadan”. Earlier, Iran rejected an Omani proposal on co-managing shipping routes through the strait.
