REGION: East Africa / Sudan
El Fasher, the capital of North Darfur and the last major Sudanese Armed Forces (SAF) stronghold in western Sudan, is now in its third week of a intensifying siege by the Rapid Support Forces (RSF), amid mounting evidence of war crimes, mass civilian displacement, and accelerating regional spillover that threatens to draw neighboring Chad and the UAE further into the conflict.
The RSF launched a full-scale assault on El Fasher on May 1, 2026, breaching the city’s outer defenses after months of incremental encirclement. The Sudanese Armed Forces, under General al-Burhan’s command, has defended the city with mechanized infantry and artillery, but intelligence assessments from the UN Mission in Sudan (UNMIS) indicate that resupply corridors have been largely severed since mid-April. The UN Office for the Coordination of Humanitarian Affairs (OCHA) estimates that more than 800,000 civilians remain trapped inside the city, with food stocks sufficient for fewer than three weeks under current distribution rates.
The UN High Commissioner for Human Rights, Volker Türk, stated on May 14 that RSF forces had committed widespread violations amounting to war crimes during the assault, including targeted attacks on civilian infrastructure, sexual violence, and the arbitrary detention of local tribal leaders aligned with the SAF. The International Criminal Court (ICC) prosecutor has publicly indicated that evidence gathered from open-source reporting and UN human rights monitors is being assessed for potential charges against RSF commander Mohamed Hamdan Dagalo (known as Hemedti).
Humanitarian access to El Fasher remains severely restricted. The World Food Programme (WFP) reported on May 16 that only 12 of 41 planned aid convoys had reached the city since the siege began, with the remaining convoys blocked at RSF checkpoints. The International Committee of the Red Cross (ICRC) has called for an immediate ceasefire to allow medical evacuations of wounded civilians, citing overwhelmed hospitals receiving up to 200 casualties per day.
The siege has also accelerated regional geopolitical spillover. Chad, which shares a 1,400-kilometer border with Sudan’s Darfur region, has reinforced its military presence along the frontier and, according to diplomatic sources cited by Reuters on May 17, has evacuated UAE diplomatic personnel from N’Djamena following intelligence assessments of heightened threat exposure. The UAE, which has deep financial ties to the RSF and has previously been accused by the UN Panel of Experts of providing weapons and logistical support to the force, denied any role in the escalation and called for an emergency African Union summit on Sudan’s crisis.
Sudan’s neighboring states are increasingly divided along proxy lines. Egypt has quietly reinforced its intelligence-sharing arrangement with the SAF, while the UAE’s long-standing relationship with the RSF has positioned it as the most influential external actor in the conflict’s trajectory. The African Union’s failure to pass a binding ceasefire resolution in April has left the UN Security Council as the primary diplomatic forum, though persistent divisions between council members on Sudan policy have limited actionable outcomes.
The siege of El Fasher represents a critical inflection point in Sudan’s broader civil war, which erupted in April 2023 following power-sharing disputes between the SAF and the RSF. The city’s fall would effectively consolidate RSF control over all of Darfur, a region that has already experienced mass atrocities attributed to RSF forces in 2023. The humanitarian consequences of a prolonged siege, combined with the active deterioration of Chad’s border stability, underscore the conflict’s transformation from a bilateral power struggle into a region-defining humanitarian and security crisis requiring urgent international diplomatic engagement.
The UN Security Council is scheduled to hold a closed-door consultation on Sudan on May 22, 2026. Diplomatic sources indicate that France and the United Kingdom are circulating a draft resolution demanding an immediate cessation of hostilities, the opening of humanitarian corridors, and the deployment of a UN monitoring mission to Darfur. The outcome of those discussions will be closely watched by regional actors and humanitarian organizations operating inside Sudan.
