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.

Onlookers gathered on Saturday at a central Tel Aviv residential building next door to Israel’s defense headquarters that was damaged after it took a hit from what appeared to be shrapnel from an overnight missile barrage from Iran.

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