The Rwandan genocide
A plane crash on 6 April 1994, set off a wave of killing in Rwanda which lasted 100 days.
Almost a million Tutsis and moderate Hutus lost their lives.
Jean-Francois Gisimba survived that time and helped hundreds of others who had taken refuge in the family-run orphanage to stay alive as well.
