United Nations Security Council resolution 1012 , adopted unanimously on 28 August 1995 , after considering the situation in Burundi , the Council established an international inquiry over the assassination of President Melchior Ndadaye during a military coup in October 1993 . On 21 October 1993 , Burundi 's first democratically elected Hutu president , Melchior Ndadaye , was assassinated by Tutsi extremists . As a result of the murder , violence broke out between the two groups , and an estimated 50,000 to 100,000 people died within a year . In 1994 , Ndadaye 's successor Cyprien Ntaryamira was assassinated in the same plane crash with Rwandan President Juvenal Habyarimana . This act marked the beginning of the Rwandan Genocide , while in Burundi , the death of Ntaryamira exacerbated the violence and unrest , although there was no general massacre . Sylvestre Ntibantunganya was installed to a 4-year presidency on 8 April , but the security situation further declined . The influx of hundreds of thousands of Rwandan refugees and the activities of armed Hutu and Tutsi groups further destabilised the regime . After considering a report from a fact-finding mission to Burundi , the Council noted that an international committee would play a role in the investigation of the coup in 1993 and the subsequent massacre . The inquiry was a recommendation of the Secretary-General Boutros Boutros-Ghali and the Government of Burundi itself had called for its establishment and the massacres to be termed '' genocide '' . Violations of international humanitarian law had been committed in Burundi and the country 's judicial system had to be strengthened . There was also serious concern about the resumption of radio broadcasts that called for ethnic hatred , and those responsible for violations would be held responsible
