UN Secretary General Ban Ki-moon arrived in the Rwandan capital of Kigali on Tuesday with the intention of discussing with the government the controversial report on alleged human rights violations involving Rwanda in the Democratic Republic of Congo, dpa reported. Ban was to meet with Rwandan's President Paul Kagame on Wednesday. Kagame has threatened to withdraw 3,500 Rwandan troops in the UN peacekeeping operation in Sudan's Darfur region if the report were to be made public. "The secretary general decided to visit Kigali to speak directly with the Rwandan president and other government officials about their concern regarding the Democratic Republic of the Congo Human Rights mapping report compiled by the Office of the High Commissioner for Human Rights" in Geneva, the UN said in New York. Ban met with Rwanda's Foreign Minister Louise Mushikiwabo after arriving in Kigali. He was accompanied by Roger Meece, the UN special representative in Congo, Alain Le Roy, chief of the UN peacekeeping operations, and Ivan Simonovic, the assistant secretary general for human rights. Ban was to return to New York on Thursday. Navi Pillay, the UN High Commissioner for Human Rights, last week postponed publication of the report for one month following Kagame's protests and after it was leaked to the French daily Le Monde. News services picked up the Le Monde story. The Geneva organization said the report - called Mapping Exercise, documenting the most serious human rights violations in Congo between 1993 and 2003 - will be made public on October 1. The report documents the killings of Hutus in Congo by Tutsi rebels operating in Congo to avenge the massacre in 1994 of an estimated 800,000 Tutsi and moderate Hutus in Rwanda under the then Hutu-government in Kigali. "Following requests, we have decided to give concerned states a further month to comment on the draft," Pillay said in Geneva last week. "And I have offered to publish any such comments alongside the report itself on 1 October, if they so wish." The leaked report angered Kagame, who won re-election for a new presidential term in Rwanda last week. He blasted Western governments for linking his government in the killing in Congo.
