Hezbollah has pounded northern Israel with 140 rockets, a day after the militant group’s leader vowed to retaliate against Israel for a mass bombing attack, the Israeli military and the militant group said.

Iran's U.N. envoy warned the country had the "right to take all necessary measures to respond to this egregious violation."

As tensions remained high Friday between Hezbollah and Israel, international leaders called for both sides to seek paths to de-escalate the conflict.
