In 1997, the International Criminal Tribunal for Rwanda – an international court established by the UN in 1994 to judge people responsible for the genocide – indicted Kabuga for his role.
It was set up to perform the remaining functions of both the Rwanda tribunal and the International Criminal Tribunal for the former Yugoslavia.
The International Criminal Court was set up to hear cases of crimes against humanity, genocide, and aggression crimes.
From my experience working in Rwanda, Rwandans perceive international-based justice as aiding the conscience of the international community, which failed to intervene before or during the genocide.
The original warrant for his arrest was issued by the now-dissolved International Criminal Tribunal for Rwanda.
