While Tutsi remained in control of Burundi , the conflict resulted in genocide in Rwanda as well . A Tutsi rebel group , the Rwandan Patriotic Front , invaded Rwanda from Uganda , which started a civil war against Rwanda 's Hutu government in 1990 . A peace agreement was signed , but violence erupted again , culminating in the Rwandan genocide of 1994 , when Hutu extremists killed an estimated 800,000 Rwandans , mostly Tutsis
