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-aligned group Hezbollah accused its arch-foe Israel of detonating pagers across Lebanon on Tuesday, a sophisticated operation that followed a series of assassinations of Israel's enemies since the Gaza war erupted on Oct.

Daily exchanges of fire between Hezbollah and Israel have been destructive, disruptive and sometimes deadly. An escalation could risk starting a wider regional conflict.
