Rwandan genocide: 25 years on, mass graves still being discovered

On Sunday April 7, Rwanda will begin marking 25 years since the devastating genocide. Over the course of just three months in 1994, between 800,000 and one million people were brutally killed. Two and a half decades later, many families have still not found the remains of their loved ones, and mass graves are still being uncovered. For survivors and their families, it’s essential this work continues, as respectful burials help bring some form of closure. Our correspondents report.
