Fifteen years ago this week, the presidents of Rwanda and Burundi, returning home from peace talks, were killed in a plane crash near the Rwandan capital, Kigali. Those deaths sparked a  killing season in both countries that was particularly brutal in Rwanda.

By June 1994 the Rwandan military - helped by Hutu civilians - had massacred at least 800,000 Tutsis and moderate Hutus -- probably more. What's happened since? A few weeks ago GRITtv spoke to Mary Kayitesi Blewitt, founder of Survivors Fund and Anne Aghion, a filmmaker and documentarian who has spent more than ten years in Rwanda.
