Rwandans and others sitting in the stands hold candles as part of a candlelit vigil during a memorial service held at Amahoro stadium in the capital Kigali on Sunday. Rwanda is commemorating the 25th anniversary of when the country descended into an orgy of violence in which some 800,000 Tutsis and moderate Hutus were massacred by the majority Hutu population over a 100-day period in what was the worst genocide in recent history.
