Hezbollah launched a barrage of 140 rockets into northern Israel on Friday, a day after its leader, Hassan Nasrallah, vowed revenge for a massive Israeli bombing, according to statements from both the Israeli military and Hezbollah.

Hezbollah admits Israel dealt a severe blow with exploding pagers and walkie talkies, but neither side seems to heed U.S. calls to avoid a wider war.

Hezbollah and Israel have traded blows in recent days, as the conflict has escalated with few off-ramps in sight to avoid total war.
