Deadly drone attacks are hitting civilians in Sudan’s Kordofan region, the United Nations has warned. The conflict between Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF) is spreading, causing devastating human suffering. UN Human Rights Chief Volker Turk told the Human Rights Council in Geneva that more violence is expected unless the world acts quickly. He called the situation a “preventable human rights catastrophe.” Turk said RSF forces took over el-Fasher, North Darfur, after an 18-month siege and committed mass killings and other serious crimes. “Responsibility for these atrocity crimes lies squarely with the [RSF] and their allies and supporters,” he said. Fighting has now expanded into central Kordofan. Both sides have used advanced drones, causing over 90 civilian deaths and 142 injuries from late January to early February, Turk reported. Recent drone strikes hit health facilities in South Kordofan, killing 31 people last week, according to the World Health Organization. On February 7, an RSF drone attack hit a vehicle with displaced families, killing at least 24 people, including 8 children, the Sudan Doctors Network said. Attacks on aid convoys and fuel trucks continue in North Kordofan. Turk also highlighted damage to the Merowe Dam and hydroelectric power station caused by RSF drone strikes. “Repeated drone strikes have disrupted power and water supplies to huge numbers of people, with a serious impact on healthcare,” he said. The UN hopes for urgent international efforts to ease the crisis and prevent further bloodshed.
