An explosion involving unexploded ordnance killed a student and injured 24 others during a school trip in northern Israel on Monday, raising fears in Lebanon of a possible retaliation.
The Israeli military, which dispatched helicopters to the scene, said an initial review showed the blast was likely caused by an unexploded munition from Hezbollah.
The explosive, which was probably a cluster bomb from a round of fighting three years ago, went off in the hands of a student who picked it up, Israeli police said.
