The IRGC closed the Strait of Hormuz after firing a warning shot at a commercial vessel that ignored orders to take an approved route, disabling the ship with fire and engine damage — a real escalation confirmed by Al Jazeera, Axios, NPR, and Fox News. The U.S. responded with a new wave of airstrikes against Iranian targets, continuing a cycle of tit-for-tat strikes that has consumed most of a failed 60-day negotiation window Trump opened in late April. The closure threatens roughly 21% of global oil shipments and drives energy prices higher, while both sides are now striking infrastructure deeper inside each other's territory — raising the risk of either an accidental strike on a third-party facility or intentional expansion beyond military targets.
