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.

The Israeli military said Iran launched retaliatory strikes throughout the night. This followed a major Israeli attack on Friday, targeting Iran's nuclear facilities and killing top military leaders.

Israeli fighter jets have been seen armed with inexpensive glide bombs. Air superiority means it doesn't need to expend costly stand-off missiles.
