Crimes committed by Rwanda's army and Congolese rebels in Congo during the 1990s could be classified as genocide, a leaked draft U.N. report says, a charge that will stir tensions between Kigali and the U.N., according to dpa. A Congo expert said diplomats were wrangling over whether to include the highly sensitive genocide accusation in the final version of the document, according to Reuters. The report details crimes committed in the former Belgian colony between 1993 and 2003, a period that saw the fall of dictator Mobutu Sese Seko and a five-year conflict involving six foreign armies, including Rwanda's Tutsi-led force. Millions of people died, most from hunger and disease rather than violence. After quashing the 1994 genocide of 800,000 Tutsis in Rwanda, Kigali's army invaded Congo, ostensibly to hunt down Hutu fighters who had taken part in the killings and then fled into the east of Congo, known then as Zaire. In the process, Rwandan forces swept the Congolese AFDL rebels of Laurent Kabila to power in Congo. Both forces have been accused of a string of rights abuses against Hutu soldiers and civilians across the country. "The systematic and widespread attacks (against Hutus in Congo) described ... reveal a number of damning elements that, if proven before a competent court, could be classified as crimes of genocide," said the report, seen by Reuters on Thursday. "The extensive use of edged weapons ... and the systematic massacres of survivors after (Hutu) camps had been taken show that the numerous deaths cannot be attributed to the hazards of war or seen as equating to collateral damage." A spokesman for the U.N.'s High Commissioner for Human Rights (UNHCHR), which drafted the 545-page report, said the leaked document was a draft, and had some errors.
