Lebanon’s Hezbollah has launched more than 100 rockets across a wider and deeper area of northern Israel, with some landing near the city of Haifa, as the sides appear to be heading for all-out war. The overnight rocket barrage set off air raid sirens across northern Israel, sending thousands of people scrambling into shelters.

Over two days, pagers and walkie-talkies used by Hezbollah detonated, wounding and even crippling some fighters, but also maiming civilians connected to the group’s social branches and killing at least two children.

The leader of Hezbollah says this week’s deadly attacks on the group’s communications devices were a “severe blow” that crossed a “red line.”
