A HAILSTORM has caused hundreds of cluster bombs to explode in south Lebanon, the National News Agency said.
The cluster bombs were dropped by Israel during its war with Hezbollah guerrillas last year.
The hailstones, as big as walnuts, fell in a number of valleys in south Lebanon, the agency said.
When cluster bombs burst, they spread bomblets over the ground and vegetation.
Air- or ground-launched, the bombs often fail to explode on impact.
Cluster bombs have killed 30 people since the war. Dozens more have been wounded.
