Although Iran maintains that its nuclear program is for peaceful energy purposes, Israel has long seen it as a threat. Israeli strikes have hit three of Iran’s nuclear facilities — Natanz, Isfahan and Fordow. Little damage appears visible in satellite imagery of Fordow.

Roughly 140 miles south of Tehran, Natanz is considered Iran’s main center for uranium enrichment, and it was a prime target of the Israeli strikes. The damage to it appeared to be severe. It is only partially underground and was recently reinforced.
