An Israeli teenager was killed and more than 20 other people injured Monday by a suspected leftover Hezbollah bomb as they hiked near the Lebanese border, officials said.
The Israeli military, which dispatched helicopters to the scene, said an initial review showed the explosion was likely caused by an unexploded munition from Lebanese militant group Hezbollah.
The explosive, which was likely a cluster bomb from a round of fighting three years ago, went off in the hands of a pupil who picked it up, Israeli police said.
Police said that school authorities had received the go-ahead for the outdoor excursion in the region, which Hezbollah has hit in successive rounds of fighting as Israel pounds the Iran-backed group.
