Israel’s military headquarters were struck after Iran’s Islamic Republic unleashed a barrage of missiles on central Tel Aviv late Friday night, causing “significant damage” to the Jewish state’s equivalent of the Pentagon.

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.

Israeli citizens were ordered to head to bomb shelters on Friday night amid retaliatory missile strikes from Iran.
