U.S. forces struck Iranian rocket launchers near Larak Island to prevent Islamic Revolutionary Guard Corps forces from deploying sea mines into the Strait of Hormuz, a U.S. official said. The official said the launchers were observed preparing to fire rockets carrying mines into the waterway, and that the U.S. military had completed clearing mines from international shipping routes the previous week. The latest account describes the operation as the first U.S. military action in a month, while an earlier report identified it as the first known strike in Iran since late July, when President Trump paused a two-week campaign. Iranian semiofficial outlets reported explosions near Larak Island, while the IRGC said several fighters and compatriots were killed or wounded and warned that the aggressor would be punished. Tasnim News Agency previously reported that a drone carried out the strike, killing two people and wounding two others. The attack came days after the Trump administration said it would prioritize economic pressure and threats against entities doing business with Tehran rather than military action. The shift follows concerns about depleted U.S. munitions stockpiles and the effect of a prolonged war on military readiness. Iran says the conflict has caused $270 billion in direct and indirect damage, while U.S. and Israeli strikes have severely damaged Iran's navy, air force and government leadership structure. Iran continues to use missiles and drones to threaten vessels in the strait, through which about 20% of the world's oil normally passes. Trump has said the waterway is open and that 24 vessels crossed last week, but that was far below the roughly 130 vessels that passed daily before the war. A U.S.-overseen multinational coalition said commercial traffic remained at reduced levels, while the United Kingdom Maritime Trade Organization said an unidentified projectile struck a tanker north of Khasab, Oman, with no reported casualties or environmental damage.
