(Washington Post) The United Nations’ top human rights official charged Friday that Sudan established, armed and supported Arab militias that allegedly expelled more than a million villagers in Sudan’s Darfur province and killed thousands. Sudanese forces and the Janjaweed militias engaged in “a reign of terror” that “may constitute war crimes and or crimes against humanity,” Bertrand G. Ramcharan, the acting U.N. high commissioner for human rights, wrote in a 16-page report on Darfur. Sudan’s U.N. ambassador, Elfatih Erwa, denied that his government armed the militias, insisting that any government killings of civilians were the accidental byproduct of a civil war that flared up in Darfur last year. The U.N. report echoed some of the key findings of a report issued Wednesday by the New York-based group Human Rights Watch. That report charged the Sudanese government with committing “ethnic cleansing,” but Ramcharan did not use the term in his report, citing the lack of an internationally recognized definition. Ramcharan, who briefed the U.N. Security Council on the U.N. mission’s findings, called for the deployment of human rights monitors in Darfur and the establishment of an international commission of inquiry to probe violations, a possible prelude to war crimes prosecution. James Morris, the American executive director of the U.N. World Food Program, also called on Sudan to meet its commitment to provide access to humanitarian relief officials in Darfur.
