Following years of ethnic strife between the Hutu majority and Tutsi minority, tensions escalated immediately after the plane of president Habyarimana was shot down on April 6, 1994. The Tutsi were designated scapegoat by Hutu extremists and subjected to a systematic and barbaric genocide. Within a hundred days, approximately 800.000 Tutsi and moderate Hutu were slaughtered. The killings only grinded to a halt when the Rwandan Patriotic Front (RPF), a Tutsi rebel militia, seized the last stronghold of the regime on July 17 that same year.
