Iran announced it had launched some 100 missiles and vowed further retaliation for sweeping attacks on its military and nuclear infrastructure.

A volley of missiles launched by Iran killed eight people and injured nearly 100 in Israel on Monday as the conflict between the two countries entered its fourth day.

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.
