JERUSALEM/BEIRUT: The Israeli military launched a wave of airstrikes against Hezbollah positions across Lebanon on Monday, marking a sharp escalation following the group's first rocket barrage since the onset of joint US-Israeli operations against Iran.

Explosions rocked the southern suburbs of Beirut, a known Hezbollah stronghold, shortly after the IDF reported multiple projectiles crossing from Lebanese territory.

While Israeli air defenses intercepted at least one launch and others fell in open areas, the exchange shattered the relative quiet maintained since a 2024 US-brokered ceasefire.

Hezbollah claimed responsibility for the initial launches, signaling a shift in its stance after previously expressing only "solidarity" with Tehran on Saturday.

The IDF confirmed no injuries or significant damage from the incoming fire but emphasized that the retaliatory strikes aim to neutralize further threats from the Iran-backed group, which remains significantly weakened from the 2024 conflict.
