Reports say the U.S. used 2,000-pound bunker-buster bombs in its latest strike on an Iranian army ammunition depot near Mount Safa in Isfahan, with secondary explosions later rocking one of the country’s largest munitions storage sites. Iran International reported smoke, fire, and repeated blasts at the depot, while citing a Wall Street Journal report that said a U.S. official confirmed the use of a high volume of penetrator munitions in the strike.
