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.

An already fragile ceasefire between Israel and the Lebanese militant group Hezbollah appeared to be on shakier ground after rockets fired from Lebanon into northern Israel triggered Israeli airstrikes in the suburbs of Beirut.

Israel said on Friday it will enforce a ceasefire in Lebanon everywhere in the country, after rocket fire prompted it to bomb Beirut for the first time during the fragile four-month-old truce with Hezbollah.
