Iran’s IRGC Navy said it struck the LPG tanker NV Sunshine as it attempted to transit through an "unauthorized route" south of the Strait of Hormuz, causing a major fire in its engine room and propulsion system.

It warned that companies cooperating with the U.S. would face sanctions and that vessels using "unauthorized routes" would be pursued and punished throughout the region, not just in the Strait of Hormuz.
