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.

Israel is attempting a risky strategy, increasing the intensity of its attacks in an attempt to force Hezbollah to back down, while raising the chances of an aggressive response that devolves into a land war.
