The Pentagon announced that “thirteen ‘fast boats’ with the Islamic Revolutionary Guard Corps Navy precariously approached U.S. Navy and Coast Guard vessels that were operating in the Strait of Hormuz. After those ships failed to heed warnings to move away to a safe distance, the U.S. fired warning shots”. A spokesperson asserted that “harassment by the IRGC Navy is not a new phenomenon… this kind of activity is the kind of activity that could lead to somebody getting hurt, and could lead to a real miscalculation in the region, and that doesn’t serve anybody’s interests”. The IRGC Navy asserted that the U.S. was “making false and unrealistic allegations”, and contended that the “Americans must strictly abide by international regulations and the laws of navigation”. The IRGC statement further characterised “the illegal, unprofessional and high-risk behavior of foreign forces, especially the U.S. Navy Fleet, which poses a threat to the maritime security of this sensitive area, as their red line”.
