A United Nations report on Israel's war on Gaza says war crimes were committed by both sides in the conflict.

But most of the criticism was directed at Israel's conduct. Richard Goldstone, the judge leading the investigation, said Israel had used excessive force and deliberately targeted Palestinian civilians.

On behalf of the UN's Human Rights Council, the investigators collected evidence, testimonies and even satellite imagery to get an idea of whether Israel or Palestinian factions were in breach of international humanitarian law.
