In November 1959, Tutsis tried to assassinate Kayibanda. Rumors of the death of Hutu politician Dominique Mbonyumutwa at the hands of Tutsis, who had beaten him, set off a violent retaliation, called the wind of destruction. Hutus killed an estimated 20,000 to 100,000 Tutsi; thousands more, including the Mwami, fled to neighboring Uganda before Belgian commandos arrived to quell the violence. Tutsi leaders accused the Belgians of abetting the Hutus. A UN special commission reported racism reminiscent of "Nazism" against the Tutsi minorities, and discriminatory actions by the government and Belgian authorities.
