Sudan Kordofan Corridor: Army Seizes al-Mazroub, UN Split on Sanctions

by

Fighting along the Sudan Kordofan corridor remains one of the decisive fronts in Sudan’s fourth year of civil war. The three Kordofan states sit between the army-held centre and east and the Rapid Support Forces’ grip on Darfur, and both sides treat the region as the logistics hinge that links those zones. On Oct. 2, the Sudanese Armed Forces said they had retaken al-Mazroub in North Kordofan, an RSF stronghold the army described as central to cutting paramilitary supply lines.

The claim lands amid a wider pattern: drone strikes on towns and aid routes, siege-like pressure on El Obeid, and a United Nations Security Council still split over whether to expand the Darfur-centred arms embargo. Our earlier coverage of Sudan’s war in Kordofan and the absence of talks sketched the stalemate; the corridor fight now shows how control of roads and junctions can matter as much as any single city.

Why the Sudan Kordofan corridor matters

Al Jazeera’s Oct. 1 mapping report described Kordofan as the corridor linking Sudan’s east and west. North, West and South Kordofan together recorded about 2,876 attacks from the start of the war in April 2023 through mid-September 2026, or roughly one in five of all recorded attacks nationwide, according to an Al Jazeera analysis of Armed Conflict Location and Event Data figures. North Kordofan alone accounted for 1,205 of those incidents, with Sheikan locality — home to the commercial hub of El Obeid — the single densest hotspot.

El Obeid links central Sudan with Darfur. Whoever holds the approaches around it can threaten the other’s rear areas or choke civilian movement. The International Organization for Migration has warned that the city, which shelters hundreds of thousands including tens of thousands of displaced people, faces the risk of a larger assault even as drone strikes and shortages of water and medicine continue. Security Council Report’s October 2026 forecast noted that the army has held the reopened Khartoum–El Obeid corridor and towns retaken in late July, while the RSF has kept contesting that route and striking El Obeid from the air.

Al-Mazroub and the push to cut RSF supply lines

In a Friday statement reported by Al Jazeera and Anadolu on Oct. 2, the Sudanese Armed Forces said fierce battles around al-Mazroub produced casualties among RSF fighters and heavy combat-vehicle losses. An army source told Al Jazeera the town had been the RSF’s largest stronghold in North Kordofan. Special Forces spokesman Mohammed Deidan told Anadolu that al-Mazroub links North and West Kordofan and that seizing it advanced the goal of severing RSF supply lines.

Independent confirmation of every battlefield claim remains difficult in a war where both sides issue victory statements and journalists face severe access limits. What is clearer is the strategic logic: if the army can hold a belt of towns between Darfur and the centre, the RSF’s ability to move fighters, fuel and drones eastward shrinks. The reverse is also true. RSF pressure on El Obeid and drone attacks on markets, colleges and food convoys aim to keep the corridor contested even when ground advances stall.

South Kordofan remains more fragmented. Localities such as Dilling and Kadugli have seen concentrated fighting, and the RSF-aligned Sudan People’s Liberation Movement-North faction adds another armed actor. A late-September accusation by the Sudan Doctors Network that SPLM-North artillery hit Dilling illustrated how ethnic and factional layers complicate any single “two-army” framing of the war.

Humanitarian pressure and UN sanctions deadlock

Security Council Report’s October forecast described El Obeid under siege-like conditions, with worsening water shortages, a cholera outbreak and mounting reports of sexual violence. Across Sudan, the World Food Programme has called the crisis the world’s largest hunger and displacement emergency, with roughly 20 million people in acute hunger and hundreds of thousands at the most extreme starvation classification. Underfunding has forced warnings of further scale-backs.

Drone strikes have hit civilians and aid operations. WFP condemned a late-August strike on food trucks outside Dilling that destroyed more than 50 metric tons of food. Separate strikes have killed civilians near courthouses and petrol stations. Those patterns sit alongside Blue Nile fighting, where an RSF/SPLM-North alliance’s gains around Kurmuk and Ed Damazin have raised concerns about cross-border supply routes and regional spillover — a theme also present in our report on a Sudan Blue Nile drone incident near the Ethiopian border.

On the diplomatic track, the Council extended the 1591 sanctions regime with a short technical rollover in mid-September after members failed to agree on a U.S.-backed draft that would have expanded the arms embargo beyond Darfur, applied it more evenly to all parties, and covered drones more explicitly. China and Russia resisted broadening the regime; African members pressed for a narrower renewal. October’s expected vote on a further extension left the same split in place: Washington and several European allies argue the Darfur-only framework is outdated, while others warn that wider coercive measures could worsen fragmentation.

What to watch next

Three indicators will show whether the Sudan Kordofan corridor fight is shifting the war or merely relocating it. First is whether the army can consolidate al-Mazroub and nearby junctions without losing El Obeid’s approaches to renewed RSF drone and ground pressure. Second is whether aid agencies can keep food and medical supplies moving through North Kordofan as winter approaches. Third is whether Security Council members produce anything beyond another short rollover when they revisit the sanctions mandate.

Mediation efforts by the Secretary-General’s personal envoy and the Quintet of African, Arab, European and UN actors have continued without a breakthrough. A U.S.-backed humanitarian truce proposal has met resistance in Khartoum, and divisions inside the Quad of Egypt, Saudi Arabia, the UAE and the United States have complicated outside leverage. For civilians along the corridor, those talks matter less than whether the next convoy reaches El Obeid intact.
