Iran’s Islamic Revolutionary Guard Corps (IRGC) attacked two supertankers in the Strait of Hormuz after the vessels allegedly ignored repeated warnings. The semi-official Tasnim News reported the incident on Tuesday, citing an IRGC statement. The United Arab Emirates earlier claimed that Iran targeted two of its oil tankers in Omani waters, resulting in the death of at least one Indian sailor. Hours later, the IRGC confirmed responsibility for the attack.

According to Iran’s state broadcaster IRIB, the IRGC said the tankers had turned off their navigation systems and were attempting to move south of Oman’s waters under U.S. direction. The statement added that both ships became disabled following the strikes.

The attack came shortly after the United States reinstated a blockade on Iran in the Strait of Hormuz. U.S. President Donald Trump announced that Washington would charge ships a 20 percent fee to ensure safe passage through the strategic waterway, declaring the U.S. would act as the “guardian” of the strait.
