Satellite photos show the aftermath of U.S. strikes that dropped 30,000-pound "bunker-buster" bombs on Iran's Fordo nuclear facility and hit the Natanz and Isfahan sites.

Iran’s army chief has warned that the US strikes on Iranian nuclear sites have given Tehran a “free hand” to "act against US interests and its army."Tehran said the American attack on its nuclear sites would have “everlasting consequences” and vowed to keep “all options” open to defend the country.

Iran has two known underground nuclear enrichment sites, the one Israel attacked on the first day of its assault at Natanz, and another at Fordo. Both sit south of Tehran in central Iran, but Fordo has long been the Iranian nuclear facility of most concern to international monitors and experts.
