Juvénal Habyarimana
On 6 April 1994, he was killed when his airplane was shot down close to Kigali. It was also carrying the President of Burundi, Cyprien Ntaryamira. His assassination caused tensions between Hutus and Tutsis to worsen, and helped start the Rwandan Genocide. Within 100 days, somewhere between 800,000 and 1 million Rwandans were massacred.
