The ordnance that exploded on schoolchildren hiking in the Ramim Ridge area in northern Israel is believed by the military to be a submunition from a Hezbollah rocket. During the war in recent years, Hezbollah launched several Grad rockets containing dozens of BRB1-type submunitions at northern Israel. The rockets spread the submunitions over wide areas, and often do not explode on impact. One of the schoolchildren is believed to have picked up a submunition during a hike along the Naftali Mountains Forest scenic route and put it in his backpack. Several minutes later, the submunition exploded, according to a preliminary probe by authorities. The blast killed a teenager and wounded 19 others, including two in serious condition and three in moderate condition.
