On April 29, there was an outbreak of violence in the south of the country, also the base of the Hima, where bands of roving Hutu committed atrocities against Tutsi civilians. All civilian and military authorities in the city of Bururi were killed and the insurgents then seized the armories in the towns of Rumonge and Nyanza-Lac. They then attempted to kill every Tutsi they could, as well as some Hutu who refused to participate in the rebellion, before retreating to Vyanda, near Bururi, and proclaiming a "Republic of Martyazo." Somewhere from 800 to 1200 people were killed.
