LONDON (Reuters) - Lebanese guerrilla group Hizbollah committed war crimes in its conflict with Israel by targeting civilians with rockets packed with metal ball bearings, rights group Amnesty International said on Thursday.

It said around a quarter of the nearly 4,000 rockets that Hizbollah launched into Israel during the 34-day war were fired directly into urban areas.

"The scale of Hizbollah's attacks on Israeli cities, towns and villages, the indiscriminate nature of the weapons used and statements from the leadership confirming their intent to target civilians make it all too clear that Hizbollah violated the laws of war," Amnesty's Secretary-General Irene Khan said.
