A UN fact-finding mission THIS WEEK determined that evidence of atrocities carried out during the siege and takeover of the Sudanese city of el-Fasher points to genocide. More than 6,000 people were killed in just three days when Sudan's paramilitary Rapid Support Forces seized the city of el-Fasher last year, according to victims and witnesses cited in the UN report. It was one of the most brutal chapters in Sudan's nearly three-year civil war and triggered widespread international outrage.There are now calls for international criminal investigations to ensure accountability for perpetrators and justice for victims, and an end to the arms flow feeding the conflict.The ongoing civil war has killed hundreds of thousands of people, and forced more than 13 million people from their homes.
