BANGKOK (AP) — In inserting itself into Israel’s war against Iran, Washington unleashed its massive “bunker-buster” bombs on Iran’s Fordo fuel enrichment plant. Those bombs were widely seen as the best chance of damaging or destroying Fordo, built deep into a mountain and untouched during Israel’s weeklong offensive. A U.S. official, speaking on condition of anonymity to discuss the operation before an official briefing, confirmed their use in Sunday’s attack. The U.S. is the only military capable of dropping the weapons. Israeli leaders had made no secret of their hopes that President Donald Trump would join their week-old war against Iran, though they had also suggested they had backup plans for destroying the site. It remained unclear early Sunday how much damage had been inflicted.
