Iran’s Islamic Revolutionary Guard Corps (IRGC) warned on May 9 that it would retaliate against any further U.S. military operations targeting Iranian commercial vessels.

“Any attack on Iranian tankers and commercial vessels will result in a heavy attack against one of the American centers in the region and enemy ships,” the IRGC Navy said in a statement shared through state media.
