UNOMUR was established to monitor the border between Uganda and Rwanda and verify that no military assistance was being provided across it. While the tragic turn of events in Rwanda in April 1994 prevented UNOMUR from fully implementing its mandate, the Mission played a useful role as a confidence-building mechanism. UNOMUR was officially closed on 21 September 1994
UNAMIR was originally established to help implement the Arusha Peace Agreement signed by the Rwandese parties on 4 August 1993. UNAMIR's mandate and strength were adjusted on a number of occasions in the face of the tragic events of the genocide and the changing situation in the country. UNAMIR's mandate came to an end on 8 March 1996
