Later, in response, Hezbollah launched more than 100 rockets, missiles and drones deep into Israel but avoided the center of the country. A video shows a direct hit on Kiryat Bialik, near the city of Haifa.

The death toll from a "targeted attack" by the Israeli military on a Beirut suburb Friday rose to 37, including seven women and three children, Lebanon's health minister said on Saturday, as Israel and the militant group Hezbollah continued to trade strikes. The U.S. also urged Americans in Lebanon to leave the country.

Israel says its strikes will intensify in a campaign that could include further offensive operations against Hezbollah, opening a new war front.
