The U.S. said they were not involved in the attack. Israel and Hezbollah exchanged strikes along the Israel-Lebanon border as Hezbollah's leader Hassan Nasrallah vowed retaliation for attacks earlier this week on his group’s communication devices. “The enemy will face a severe and fair punishment from where they expect and don’t expect,” Nasrallah said. The leader of Hezbollah said Thursday the mass bombing attack on the group’s communications devices in Lebanon and Syria was a “severe blow” and said Israel had crossed a “red line.” But he vowed the group would emerge stronger and continue its daily strikes into northern Israel. As Hassan Nasrallah spoke in a televised speech from an unknown location, Hezbollah and the Israeli military traded new strikes over the border. Israeli war planes flew low over Beirut and broke the sound barrier, scattering birds and prompting people in houses and offices to quickly open windows to prevent them from shattering. Fears are rising that 11 months of exchanges of fire between the two sides will escalate into all-out war, particularly after this week's unprecedented bombings, which detonated hundreds of pagers and walkie- talkies used by Hezbollah.
