The atrocities unleashed on Sudan¡¯s El-Fasher last October were a ¡°preventable human rights catastrophe,¡± the U.N. human rights chief said Monday, warning they now risked being repeated in Kordofan.

Giving the U.N. Human Rights Council an update on the situation in El-Fasher, Volker Turk decried the horrific scenes after the paramilitary Rapid Support Forces (RSF) unleashed a ¡°wave of intense violence,¡± following 18 months of brutal siege.

¡°Thousands of people were killed in a matter of days, and tens of thousands fled in terror,¡± he said, stressing the need to ¡°hold those responsible accountable, and to make sure this never happens again.¡±
