AN unofficial report alleging Rwandan strongman Paul Kagame’s involvement in the 1994 assassination of his country’s president has been found in United Nations files, a UN source said on Monday. The source says “the so-called report” had been written by Michael Hourigan, a former investigator for the international Rwandan war-crimes tribunal in Arusha, and was not an official UN document. But, he says, it had been forwarded to the tribunal on the orders of UN Secretary General Kofi Annan “so that if the matter is raised before the tribunal, the appropriate authority can decide whether to use it” The report alleges that three Rwandan informants were part of an elite strike team lead by Kagame, that shot down the plane of president Juvenal Habyarimana in 1994, sparking the Rwandan genocide in which an estimated 500000 people, most of them Tutsis, were slaughtered.
