Israel's military says its air force struck sites belonging to Hezbollah in Lebanon. The strikes in Bekaa Valley on Monday night came as Israeli Prime Minister Benjamin Netanyahu vowed to intensify attacks in the latest Israel-Hezbollah war. The Lebanese militant group has been firing fiber optic drones at Israeli forces. Despite a U.S.-brokered ceasefire since April, tensions remain high. A U.S. State Department official says Hezbollah has ignored requests to stop firing. Monday's escalation comes as Lebanese and Israeli officials are set to meet on Friday at the Pentagon to discuss the ceasefire.
