Beirut, Lebanon ? A rights group reported Thursday for the first time that Hezbollah fired cluster bombs at civilian areas in northern Israel during their summer war, although the number of strikes was a fraction of what Israel dropped on Lebanon.

Human Rights Watch said in a report that three Israeli civilians were injured when at least two cluster munitions landed July 25 between three homes in the Galilee village of Maghar.

The New York-based group and the United Nations have accused Israel of firing as many as 4 million cluster munitions into Lebanon, leaving unexploded ordnance that still threatens Lebanese civilians. Since the Israel-Hezbollah war ended Aug. 14, these duds have killed 20 Lebanese civilians and wounded 120 others, most of them children.
