Fasher, the capital of North Darfur state, in what the United Nations chief called a “terrible escalation” in the conflict.

The paramilitary group RSF has been going door to door to find and kill non-Arabs in El-Fasher, the city in Sudan’s Darfur region they recently captured, and dumping the dead in piles. The scale of massacres is such that piles of bodies and pools of blood are visible in satellite imagery.

Sudan's RSF paramilitary forces reportedly launch an attack on the army's last stronghold in Darfur, where tens of thousands of civilians are trapped.

More than two years after the start of Sudan's civil war, the nation's military has ceded nearly all of Darfur to a paramilitary group in an effort to prevent more death and destruction there.
