A U.S. official said that six American warplanes dropped a dozen 30,000-pound bunker-busters on the Fordo nuclear site, and that Navy submarines fired 30 cruise missiles at the Natanz and Isfahan sites. One B-2 bomber also dropped two bunker-busters on Natanz, the official said.

It was an unprecedented attack years in the making, with some last-minute misdirection meant to give the operation a powerful element of surprise.

Iran's military launched dozens of missiles into Israel on Saturday night after President Donald Trump ordered U.S. airstrikes against three Iranian nuclear sites at Fordow, Natanz and Isfahan. Trump and other world leaders have called on Iran to come to the negotiating table.
