The Islamic Revolutionary Guard Corps targeted tankers traversing the southern Omani corridor during a series of naval engagements over the weekend. The IRGC-affiliated Fars News Agency claims 19 vessels were struck for taking unauthorized routes, with 12 attacks occurring on Friday and seven on Saturday. A U.S. official told Axios that zero ships were hit over the last two days, a discrepancy that observers have called an unusually wide spread in conflict reporting. Iran utilized cruise missiles, attack drones, and speedboats armed with guided rockets and machine guns to engage shipping.

Daily crossings for large commodity vessels through the waterway have fallen to as few as 2 ships, down from approximately 125 per day before the war. U.S. Ambassador to the UN Mike Waltz said a record 146 countries have joined the U.S. in condemning Tehran's actions as violations of international law. These attacks coincide with reports that Iran is laying naval mines in the strait after Donald Trump rejected a ceasefire and negotiation proposal.
