Sudan’s warring parties rejected a call by U.N. experts to deploy an international force to protect civilians from the devastating civil war which erupted last April. A U.N. fact-finding mission reported “harrowing” human rights abuses committed by both the Sudanese army and the paramilitary Rapid Support Forces. The World Health Organization’s Tedros Adhanom Ghebreyesus visited Port Sudan over the weekend.

Tedros Adhanom Ghebreyesus: “According to available data, the Sudanese conflict has so far killed more than 20,000 people — this is an underestimate, by the way — displaced over 10 million people inside the country and forced another 2 million to flee to neighboring countries. This is the largest internal displacement of people in the world today. The scale of the emergency is shocking, and, as is, the insufficient action being taken to curtail the conflict and respond to the suffering it’s causing.”

This comes as new video has emerged from Sudan showing the aftermath of an ethnically motivated massacre by RSF fighters in Darfur’s Kassab camp and the town of Kutum last year. The attack killed an estimated 73 people. The RSF have been accused of many other deadly attacks on Black Sudanese communities.
