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

Iran has launched more missiles at Israel early Monday morning, according to the Israel Defense Forces. Warning sirens were activated in several areas of the country, including Tel Aviv and Jerusalem. The IDF said the Israeli Air Force was working to "intercept and strike where necessary to eliminate the threat."

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.
