The US concentrated its attack on Fordow, an enrichment plant built hundreds of feet underground. Aerial photos give important clues about what damage the “bunker-buster” bombs may have caused.

The strikes appear to have blocked entrances leading and destroyed some buildings, per newly released satellite images.

Three nuclear facilities were targeted - Fordo, Natanz and Isfahan, the US said. During a Pentagon briefing, Caine said bombers set off from the US on an 18-hour flight, with some heading west into the Pacific as a "decoy", while the main strike package made up of the seven B-2 bombers proceeded into Iran.
