Israel said on Friday it will strike anywhere in Lebanon it sees a threat, after rocket fire prompted it to bomb Beirut for the first time during the fragile four-month-old truce with Hezbollah. It was the second time rockets had been launched at Israel from Lebanon since the November ceasefire -- the first was last Saturday -- and the second time Iran-backed Hezbollah denied involvement.

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.
