Former mayor of Kivumu, Kibuye prefecture in Rwanda, Grégoire Ndahimana today pleaded not guilty to all the charges brought against him by the Prosecutor. He entered the plea during his initial appearance before Judge Khalida Rachid Khan. Ndahimana was one of the thirteen fugitives who are still at large.

On 10 June 2001, he was indicted by the Tribunal and had been on the run since that time. He is charged with four counts of genocide; or in the alternative, complicity in genocide; conspiracy to commit genocide, and crimes against humanity for extermination.

According to the indictment, Ndahimana is alleged to have been, on or between the dates of 6 April 1994 and 20 April 1994, in Kivumu commune, responsible for killing or causing serious bodily or mental harm to members of the Tutsi population. He is alleged to have planned the massacres of members of the population of mostly tutsi ethnic group who had sought refuge at the Nyange Parish, jointly with Father Athanase Seromba (sentenced to 15 years in the first instance and to imprisonment for the remainder of his life after dismissal of his appeal) and Fulgence Kayishema (still at large).

Ndahimana, 57, was arrested on 10 August 2009 at Kachuga Camp in North Kivu, Democratic Republic of Congo (DRC) during a combined operation by the ICTR, the United Nations Mission in the DRC (MONUC) and the DRC law enforcement agencies. He was transferred to the United Nations Detention Facility in Arusha on 21 September 2009.
