ATTENTION EDITORS – VISUAL COVERAGE OF SCENES OF INJURY OR DEATH A Rwandan boy covers his face from the stench of dead bodies in this July 19, 1994 file photo. April 7, 2014 marks the 20th anniversary of the Rwanda genocide which killed 800,000 people. The three-month killing spree in 1994 by Hutu extremists targeted ethnic Tutsis, but moderate Hutus were also caught in the wave of violence that followed the fatal downing of a plane carrying Rwandan President Juvenal Habyarimana.
