US Navy Fires on Iranian Ship — Marines Board & Seize

U.S. Navy warships opened fire on an Iranian vessel in the Persian Gulf on April 16, 2026, after it refused to heed warnings and attempted to breach the American naval blockade of the Strait of Hormuz. Following a brief exchange of fire that disabled the ship, U.S. Marines from the 31st Marine Expeditionary Unit conducted a rapid boarding operation, seizing the vessel and its crew.
