Genocidaires

Génocidaires (, "those who commit genocide") are those guilty of the mass killings of the 1994 Rwandan Genocide, in which close to a million Rwandans, primarily Tutsis, were murdered by their Hutu neighbors. In the aftermath of the genocide, those guilty of organizing and leading the genocide were put on trial at the International Criminal Tribunal for Rwanda. Those guilty of lesser crimes—participation, profiting through seizing Tutsi property, etc.—were put on trial in gacaca courts.

The term is also used more broadly to refer to any perpetrator of genocide.
