This harrowing report from Amnesty International details abuses by human rights by armed groups in Iraq saying amongst other things that Many of these killings by armed groups, in Amnesty Internationals view, constitute war crimes or crimes against humanity. As such, there is an obligation on both the Iraqi government and the international community at large to ensure that the perpetrators of these crimes are identified and brought to justice. There can be no excuse for such abuses; international humanitarian law clearly distinguishes certain acts as crimes irrespective of the causes of a conflict or the grounds on which the contending parties justify their involvement.
