Lieutenant-Colonel Nsengiyumva is facing eleven counts charging with conspiracy to commit genocide, genocide, complicity in genocide, direct and public incitement to commit genocide, crimes against humanity for murder, extermination, rape, persecution and other inhumane acts.

The accused is alleged to have conspired with others to work out a plan with the intent to exterminate the civilian Tutsi population and eliminate members of the opposition. The components of this plan consisted of, among other things, recourse to hatred and ethnic violence, training and distribution of weapons to militiamen as well as the preparation of lists of people to be eliminated. Nsengiyumva and his group are alleged to have organised, ordered and participated in the massacres perpetrated against the Tutsi population and moderate Hutus.

Nsengiyumva was arrested on 27 March 1996 in Cameroon and was transferred to the UN Detention Facility in Arusha on 23 January 1997. He made his initial appearance before the Tribunal on 19 February 1997 and pleaded not guilty to all the charges preferred against him.

Major Ntabakuze and Brigadier-General Kabiligi are facing ten counts in a joint indictment charging them with genocide, conspiracy to commit genocide, genocide, complicity in genocide, direct and public incitement to commit genocide, crimes against humanity for murder, extermination, rape, persecution and other inhumane acts.
