‘This is the last warning:’ Iran radioes U.S. during Strait of Hormuz de-mining effort | 12 April 2026 | After the U.S. military launched operations to de-mine the Strait of Hormuz, the Islamic Revolutionary Guard Corps (IRGC) Navy reportedly warned an American destroyer in the passageway. “This is the last warning. This is the last warning,” the Iranian forces radioed to one of the two U.S. destroyers in the strait, according to the Wall Street Journal. “Passage in accordance with international law. No challenge is intended to you, and I intend to abide by rules of our government’s cease-fire,” the U.S. ship responded, referring to the temporary pause in hostilities between the two sides. The U.S. has reached out to U.S. Central Command (Centcom) for comment on the reported radio message. The IRGC Navy, meanwhile, denied Saturday that U.S. ships passed through the Strait.
