Fears of renewed ethnic slaughter in the Sudanese region of Darfur have increased, particularly with the looming assault on the city of El Fasher, which is already facing a threat of famine. The U.S. envoy to the United Nations, Linda Thomas-Greenfield, warned of a potential large-scale massacre in the city. The civil war between Sudan’s military and the Rapid Support Forces has caused widespread devastation in the region, creating a massive humanitarian crisis.
