Rwanda's genocide erupted 10 years ago, with a savagery and thoroughness that shocked the international community. In just 100 days, an estimated 500,000 to 800,000 Tutsis were killed. The killing was particularly efficient in the remote western province of Kibuye, where 22-year-old Immaculee Ilibagiza lived with her Tutsi family. Now a UN employee in New York, Ilibagiza shares with RFE/RL a personal tale about the genocide.
