The leader of Lebanon’s Hezbollah group has warned that if Israel’s attacks on Lebanon continue and the Lebanese state does not act to stop them, the group will eventually resort to other alternatives.

Israel launched an airstrike on Beirut for the first time since a U.S.-backed cease-fire took effect in November, amid growing frustrations among some American officials about the Lebanese government’s slow progress in disarming Hezbollah in the country’s south.

Israel on Friday carried out its first major airstrike on Beirut's southern suburbs in months, retaliating for an earlier rocket launch from Lebanon in the most serious test of a shaky ceasefire deal agreed in November.
