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 launched an attack on Lebanon’s capital for the first time since a cease-fire ended the latest Israel-Hezbollah war in November. Associated Press reporters in Beirut heard a loud boom and witnessed smoke rising from an area in the city’s southern suburbs that Israel’s military had vowed to strike.

First airstrikes on Lebanese capital since ceasefire announced in November; one rocket intercepted, second failed to cross border; Hezbollah says it is not behind rocket attack
