The United Nations’ top human rights official is warning the power struggle in South Sudan is tearing the country apart. Thousands have died and more than one million people have fled their homes since clashes erupted between government troops and supporters of the country’s sacked vice president late last year. On Wednesday, Navi Pillay said South Sudan is on the verge of catastrophe.

Navi Pillay: “The country’s leaders, instead of seizing their chance to steer their impoverished and war-battered young nation to stability and greater prosperity, have instead embarked on a personal power struggle that has brought their people to the verge of catastrophe.”
