The Ikiza (translated variously from Kirundi as the Catastrophe, Great Calamity) or the Ubwicanyi (Killings) was a series of mass killings—often characterised as a genocide—which were committed in Burundi in 1972 by the Tutsi-dominated army and government against the Hutus who lived in the country. Conservative estimates place the death toll of the event between 100,000 and 150,000 killed, while some estimates of the death toll go as high as 300,000.
