(CNN) -- The human rights group Amnesty International is calling on the United Nations to impose an arms embargo on Israel and the Palestinians, saying both sides used weapons supplied from abroad to carry out attacks on civilians during their three-week conflict in Gaza. Palestinian children make coffee behind a bullet and rocket riddled wall in Rafah, Gaza, on January 24, 2009. The London-based group issued a 38-page report Sunday night that detailed "evidence of war crimes and other serious violations of international law by all parties." Israeli forces used white phosphorus and other weapons supplied by the United States, killing hundreds of civilians and destroying homes, the group said.
