Hezbollah has launched over 100 rockets across a wider and deeper area of northern Israel, with some landing near the city of Haifa, as the sides appeared to be spiraling toward all-out war following months of escalating tensions.

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.

Israel claimed the death of a senior Hezbollah military official after a rare Israeli airstrike on Beirut as the death toll rose Saturday to at least 37 people, with dozens more wounded, shortly after Hezbollah pounded northern Israel with 140 rockets.
