The UN peacekeeping force, UNAMIR, was in Rwanda during the genocide, but its Chapter VI mandate rendered it powerless to intervene militarily. Efforts by General Dallaire to broker peace were unsuccessful, and most of UNAMIR's Rwandan staff were killed in the early days of the genocide, severely limiting its ability to operate. Its most significant contribution was to provide refuge for thousands of Tutsi and moderate Hutu at its headquarters in Amahoro Stadium, as well as other secure UN sites, and to assist with the evacuation of foreign nationals. The Belgian Government, which had been one of the largest troop contributors to UNAMIR, pulled out in mid-April following the deaths of its ten soldiers protecting Prime Minister Uwilingiliyimana. In mid-May the UN conceded that "acts of genocide may have been committed", and agreed to reinforcement. The new soldiers started arriving in June, and following the end of the genocide in July they stayed to maintain security and stability, until the termination of their mission in 1996. Fifteen UN soldiers were killed in Rwanda between April and July 1994, including the ten Belgians, three Ghanaians, an Uruguayan, and Senegalese Mbaye Diagne who risked his life repeatedly to save Rwandans.
