United Nations officials are warning that extreme insecurity and appalling human rights violations — including mass killings, ethnic violence, and sexual violence — in the Sudanese town of El Fasher, the capital of North Darfur State, have triggered a dramatic surge in people forced to flee and further worsened the country's humanitarian crisis. Despite rising needs, humanitarian operations in North Darfur are on the brink of collapse in the face of severe funding shortages for the Sudan emergency.
