Sudan’s war is increasingly difficult to understand as a purely domestic contest between the Sudanese Armed Forces and the Rapid Support Forces. By September 2026, United Nations investigators were describing a wider system of foreign recruitment, logistics, weapons and drone capabilities feeding the conflict. The humanitarian emergency is the point where those networks become visible to civilians.
On Sept. 3, the UN Independent International Fact-Finding Mission for Sudan said foreign recruitment and external support networks were strengthening the military capabilities of the warring parties. The mission reported transnational networks that supported the RSF with personnel, training, weapons and logistics, including the deployment of up to 2,000 former Colombian military contractors. It also said there were reasonable grounds to believe the SAF had used foreign-supplied drones in operations that harmed civilians and civilian objects.
The mission’s findings extend earlier concerns documented by UN human-rights mechanisms about foreign military and logistical support, mercenary-related actors and interference in the conflict. The significance is strategic: modern capabilities can move across borders even when front lines inside Sudan remain fragmented. Drones, contractors, supply corridors and financing can prolong a war beyond the capacity of Sudanese civilian institutions to absorb its costs.
Those costs are now heavily concentrated in Kordofan. WFP has called El Obeid a new epicenter of displacement and hunger. On Aug. 30, an aerial attack outside Dilling struck two clearly marked WFP trucks en route to Kadugli. More than 50 metric tons of food were destroyed, enough for 5,800 people for a month. WFP said eight aerial attacks had damaged its premises or disrupted operations since the start of 2026.
The attack is a small piece of a much larger supply problem. About 19.5 million people have faced acute food insecurity at IPC Phase 3 or worse. Analysts projected that as many as 200,000 could be in Catastrophe conditions during the June-to-September lean season. Famine risk was identified in 14 areas through September and expected to persist in 13 areas into January 2027.
Displacement is similarly networked across regions and borders. IOM estimated 8.62 million internally displaced people in July and nearly 4.93 million returnees. UNHCR’s wider crisis portal, combining conflict-linked internal displacement with people outside Sudan, recorded more than 11.29 million forcibly displaced people by Aug. 24. Movements now run in both directions: return toward less active fronts, and renewed flight from emerging ones.
The health system shows how military networks translate into institutional breakdown. WHO reported that 37 percent of health facilities were nonfunctional and about 21 million people lacked needed health services. Since April 2023, it had verified 217 attacks on health care. A new cholera vaccination campaign began in early September in parts of Darfur and West Kordofan, illustrating how war and public-health logistics compete for the same roads and security space.
Humanitarian agencies still operate at a scale few other institutions in Sudan can match. WFP says it reaches more than four million people a month. UNICEF supported screening of 1.43 million children for acute malnutrition in July. Yet funding gaps remain severe and access can be lost abruptly after a strike or road closure.
The strategic question for outside governments is therefore not limited to diplomacy between the two main armed camps. It includes control over the transnational systems that keep sophisticated weapons, personnel and logistics moving while food, medicine and water struggle to reach civilians. Sudan’s humanitarian crisis will remain difficult to contain as long as the military networks are more resilient than the networks sustaining civilian life.
