The situation worsened when the first elected Burundian president, Melchior Ndadaye, a Hutu, was assassinated by the Burundian Tutsi-dominated army in October 1993. In Burundi, a fierce civil war then erupted between Tutsi and Hutu following the army's massacre. This conflict spilled over the border into Rwanda and destabilized the fragile Rwandan accords. Tutsi-Hutu tensions rapidly intensified. Although the UN sent a peacekeeping force named the United Nations Assistance Mission for Rwanda (UNAMIR), it was underfunded, under-staffed, and largely ineffective in the face of a two country civil-war. The UN denied Lieutenant-General Roméo Dallaire's request for additional troops and changes to the rules of engagement to prevent the coming genocide.
