Report of the International Commission of Inquiry on Darfur to the United Nations Secretary-General Pursuant to Security Council Resolution 1564 of 18 September 2004, January 25, 2005. Excerpt from the executive summary:

Based on a thorough analysis of the information gathered in the course of its investigations, the Commission established that the Government of the Sudan and the Janjaweed are responsible for serious violations of international human rights and humanitarian law amounting to crimes under international law. In particular, the Commission found that Government forces and militias conducted indiscriminate attacks, including killing of civilians, torture, enforced disappearances, destruction of villages, rape and other forms of sexual violence, pillaging and forced displacement, hroughout Darfur. These acts were conducted on a widespread and systematic basis, and therefore may amount to crimes against humanity. The extensive destruction and displacement have resulted in a loss of livelihood and means of survival for countless women, men and children. In addition to the large scale attacks, many people have been arrested and detained, and many have been held incommunicado for prolonged periods and tortured. The vast majority of the victims of all of these violations have been from the Fur, Zaghawa, Massalit, Jebel, Aranga and other so-called 'African' tribes….

The Commission concluded that the Government of the Sudan has not pursued a policy of genocide. Arguably, two elements of genocide might be deduced from the gross violations of human rights perpetrated by Government forces and the militias under their control. These two elements are, first, the actus reus consisting of killing, or causing serious bodily or mental harm, or deliberately inflicting conditions of life likely to bring about physical destruction; and, second, on the basis of a subjective standard, the existence of a protected group being targeted by the authors of criminal conduct. However, the crucial element of genocidal intent appears to be missing, at least as far as the central Government authorities are concerned. Generally speaking the policy of attacking, killing and forcibly displacing members of some tribes does not evince a specific intent to annihilate, in whole or in part, a group distinguished on racial, ethnic, national or religious grounds. Rather, it would seem that those who planned and organized attacks on villages pursued the intent to drive the victims from their homes, primarily for purposes of counter-insurgency warfare.
