Following Habyarimana's death, a military committee led by Colonel Théoneste Bagosora took immediate control of the country. Under the committee's direction, the Hutu militia Interahamwe and the Presidential Guard began to kill Hutu and Tutsi opposition politicians and other prominent Tutsi figures; within 24 hours they had killed all moderate leaders, including Prime Minister Agathe Uwilingiyimana. The killers then began targeting the entire Tutsi population, as well as moderate Hutu, beginning the Rwandan genocide. Over the course of approximately 100 days, an estimated 500,000 to 800,000 Tutsi and moderate Hutu were murdered.
