The UN human rights chief also condemned the “preventable human rights disaster” in Sudan’s El Fasher.

The central region of Sudan’s Kordofan state has become the latest frontline in Sudan’s nearly three-year conflict, with deadly drone attacks targeting civilians continuing, the United Nations says.

Speaking at the Human Rights Council in Geneva on Monday, United Nations High Commissioner for Human Rights Volker Turk paints a grim picture of conflict between Sudanese Armed Forces (SAF) and paramilitary forces rapid support force Doctors Without Borders (RSF) plunged the country into widespread bloodshed and humanitarian disaster.

Turk said that unless the international community takes decisive measures to stop the fighting, “we can only foresee the worse to come.” He stressed that failure to take action would lead to greater terror.

Turk also highlighted harrowing survivor testimonies from El Fasher, the capital of North Darfur state, which fell to Doctors Without Borders in October after an 18-month siege. He described atrocities committed by paramilitary forces after they captured cities, including mass killings and other serious violations against civilians.

“Responsibility for these atrocities lies solely with Doctors Without Borders and its allies and supporters,” he said

As Sudan’s devastating civil war spreads from western Darfur to the central Kordofan region, Turk warned that the shift in fighting could bring more serious violations against civilians. He expressed deep concern about the possibility of more serious violations, highlighting the increasing use of “advanced drone weapons systems” by the warring parties.

“Over the past two weeks, joint Sudanese armed forces and allied forces have broken the siege of Kadugli and Dirin,” Turk said. “But drone attacks from both sides have continued, resulting in dozens of civilian casualties.”

Turk’s office documented the deaths of more than 90 civilians and the injury of 142 others in drone strikes carried out by Médecins Sans Frontières and the armed forces between late January and February 6, he said.

The incidents include three attacks on health facilities in South Kordofan state last week that killed 31 people, according to the World Health Organization.

The Sudanese Doctors Network said that on February 7, Doctors Without Borders launched a drone attack in central Sudan and hit a vehicle transporting displaced families, killing at least 24 people, including 8 children.

The latest attack follows a series of drone attacks on humanitarian aid convoys and fuel trucks in North Kordofan state.

The United Nations High Commissioner for Human Rights said he had witnessed first-hand the devastation caused by Médecins Sans Frontières’ attack on the Melovi Dam and its hydroelectric power station in Sudan.

“Repeated drone strikes have disrupted power and water supplies for large numbers of people, with severe consequences for health care,” he said.
