Hezbollah launched more than 100 rockets early Sunday across a wider and deeper area of northern Israel, with some landing near the city of Haifa, as Israel launched hundreds of strikes on Lebanon. The sides appeared to be spiralling toward all-out war following months of escalating tensions.

The rocket barrage overnight set off air raid sirens across northern Israel, sending thousands of people scrambling into shelters. The Israeli military said that rockets had been fired “toward civilian areas”, pointing to a possible escalation after previous barrages had mainly been aimed at military targets.
