Sudan Conflict: South Kordofan Escalation and External Support

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-09-05 22:08Z · Overall confidence: HIGH

BLUF

Fresh attacks in Debi, Luwairi and Dilling in South Kordofan, alongside SAF, RSF and SPLM-N activity in Blue Nile, make continued civilian harm and displacement very likely over the next 30 days. UN reporting indicates that foreign networks are sustaining RSF capabilities, but direct UAE responsibility and current control of Al-Kurmuk remain unresolved.

Executive summary

The conflict is showing fresh pressure in South Kordofan and Blue Nile. Reports on 3 to 5 September said SPLM-N attacks in Debi, Luwairi and Dilling killed at least 26 people and injured dozens, including civilians, while SAF, RSF and SPLM-N forces continued military activity near the Ethiopian border. The UN fact-finding mission has documented foreign fighters and supply networks supporting the RSF, including routes through Chad, southeastern Libya and Bosaso. Humanitarian conditions remain severe, with around 21 million people requiring food assistance, more than 100,000 facing displacement in Darfur and Kordofan, and humanitarian workers estimating more than 200,000 conflict-related deaths. The main uncertainties are the attribution of external support, the current status of Al-Kurmuk and RSF-held bases near Ed Damazin, and the reliability of varying casualty and displacement estimates.

Change from previous assessment

Since the 4 September brief, the assessment gives greater weight to South Kordofan as an active civilian-harm front after reported SPLM-N attacks in Debi, Luwairi and Dilling. Blue Nile is now treated as a distinct area of unresolved territorial control and continuing military pressure, rather than only as background to regional escalation. The cross-border warning is retained at roughly even chance, with confidence raised from low to medium because reporting now includes US condemnation of SAF airstrikes inside Chad and continuing Sudan-Ethiopia accusations. The judgments on RSF external support, humanitarian deterioration, international pressure and Darfur civilian protection are retained, with the UAE attribution caveat made more explicit.

Key judgments

1. The RSF is very likely to retain access to foreign personnel, training, weapons and logistics over the next 1-3 months. The UN mission reported up to 2,000 former Colombian army contractors operating with RSF units in Darfur and Kordofan, and identified networks linked to Colombia and the UAE using routes through Chad, southeastern Libya and Bosaso to move people and weapons. This does not establish direct UAE government responsibility, which remains disputed by the UAE mission in Geneva. (Confidence: medium · ASSESSED)

• I&W: Confirm: reporting identifies additional Colombian contractors, recruitment activity, weapons deliveries or logistics movement through Chad, southeastern Libya or Bosaso. (0-3 months)
• I&W: Break: the UN mission or independent reporting documents a sustained halt in the identified routes and no new RSF foreign personnel or materiel. (1-3 months)

2. Further attacks in South Kordofan are very likely over the next 30 days, while military pressure involving the SAF, RSF and SPLM-N in Blue Nile is likely to persist. Multiple reports attributed the deaths in Debi, Luwairi and Dilling to SPLM-N forces, while separate reporting recorded SAF reinforcements and RSF territorial claims near the Ethiopian border. (Confidence: high · ASSESSED)

• I&W: Confirm: SPLM-N conducts another artillery or ground attack in Dilling, Debi or Luwairi that causes civilian casualties. (0-14 days)
• I&W: Break: reporting records no further attacks and no additional SAF, RSF or SPLM-N reinforcement in South Kordofan or Blue Nile. (0-30 days)

3. Humanitarian conditions in Darfur and Kordofan are very likely to worsen over the next 30 days. International organisations report that more than 100,000 people face displacement in the two regions, while around 21 million people across Sudan require food assistance. Humanitarian workers estimate more than 200,000 deaths and more than 12 million displaced people. Exact totals remain uncertain because the estimates use different dates, definitions and methods. (Confidence: medium · ASSESSED)

• I&W: Confirm: international organisations report new displacement from Darfur or Kordofan, or an increase above the current estimate of more than 100,000 people facing displacement. (0-30 days)
• I&W: Break: humanitarian organisations verify sustained reductions in displacement and restored access to affected communities in Darfur and Kordofan. (1-3 months)

4. A further cross-border military incident involving the SAF and Chad has a roughly even chance over the next 1-3 months, while a broader regional conflict remains unlikely. Reporting attributes a recent border strike that killed 12 people to the Sudanese army, Chad and the United States condemned SAF airstrikes inside Chad, and Sudan and Ethiopia exchanged accusations over support to hostile forces. The evidence remains thin and the attribution of the border strike is contested. (Confidence: medium · ASSESSED)

• I&W: Confirm: Chad or the United States reports another SAF-attributed strike inside Chad that causes deaths, or Chad conducts a military response. (1-3 months)
• I&W: Break: Sudan and Chad reduce their public accusations and no cross-border strike or military response is reported. (1-3 months)

5. International pressure to restrict external support is very likely to intensify over the next 1-3 months, but disruption of the identified RSF supply routes is unlikely in that period. The UN mission and the US have called for wider arms restrictions and targeted sanctions, while the UN has described networks operating across Colombia, the UAE, Chad, Libya, Somalia and Ethiopia. Current reporting documents proposals and allegations, not enforcement that has interrupted the routes. (Confidence: medium · ASSESSED)

• I&W: Confirm: the UN Security Council adopts a nationwide arms embargo or targeted sanctions linked to the Sudan conflict. (1-3 months)
• I&W: Break: authorities document interdictions or sustained closures affecting transfers through Chad, southeastern Libya or Bosaso. (1-3 months)

6. Severe civilian-protection risks in El Fasher, Zamzam and West Darfur are very likely to persist over the next 1-3 months. The UN mission documented killings, abuses displaying hallmarks of genocide and violations linked to RSF operations around Zamzam and El Fasher, while current reporting records detention of civilians accused of supporting the SAF in West Darfur and El Geneina. The strongest evidence concerns past abuses, so the timing of new incidents remains insufficiently reported. (Confidence: medium · ASSESSED)

• I&W: Confirm: new reports document detention, killings or attacks against civilians in El Geneina, West Darfur, El Fasher or around Zamzam. (0-3 months)
• I&W: Break: UN or international organisations verify no new abuses in these locations and sustained improvement in civilian access and protection. (1-3 months)

7. Fighting around Al-Kurmuk and Ed Damazin is likely to continue over the next 30 days, but current control of Al-Kurmuk and two military bases southeast of Ed Damazin is unresolved. The governor of Blue Nile described the security situation as under control, while the RSF announced control of Al-Kurmuk and the two bases. This contradiction lowers confidence in the territorial picture. (Confidence: medium · ASSESSED)

• I&W: Confirm: independent reporting verifies RSF control of Al-Kurmuk or the two bases and records further fighting near Ed Damazin. (0-30 days)
• I&W: Break: independent reporting establishes one force's control of the disputed positions and records no further clashes around Al-Kurmuk or Ed Damazin. (0-30 days)

Outlook & scenarios

Continued multi-front attrition (65%)

The SAF, RSF and SPLM-N continue fighting in South Kordofan and Blue Nile while RSF support routes remain active. Civilian deaths, displacement and food-assistance needs rise in Darfur and Kordofan. External pressure produces further statements and proposals but no verified interruption of the routes.

Blue Nile and border escalation (25%)

Fighting around Al-Kurmuk and Ed Damazin expands towards the Ethiopian border, followed by another SAF-Chad incident. The conflict acquires a stronger regional dimension, while competing claims over territorial control remain unresolved.

External pressure begins to constrain support (15%)

The UN Security Council adopts nationwide arms restrictions or targeted sanctions, and states along the reported routes act against transfers. RSF access to foreign personnel, weapons or logistics narrows, although fighting and civilian harm continue inside Sudan.

Wildcard: sustained interstate confrontation (8%)

Another SAF or RSF-linked cross-border strike prompts retaliation by Chad or Ethiopia. Sudan's conflict develops into sustained interstate confrontation, with sharper risks to civilians and humanitarian access.

Recommendations

1. Prioritise collection on Debi, Luwairi and Dilling, including confirmation of SPLM-N involvement, civilian casualty figures and any further artillery or ground attacks.
2. Track SAF, RSF and SPLM-N deployments around Al-Kurmuk and Ed Damazin separately from public claims of territorial control. Require independent confirmation before treating either side's claims as established.
3. Monitor the Sudan-Chad border, southeastern Libya, Bosaso and the Ethiopia-Sudan border for evidence of personnel, weapons or logistics movement. Separate reporting on private networks from allegations of direct government involvement.
4. Maintain separate casualty and displacement series for Darfur, Kordofan and Sudan as a whole. Record the reporting date, geographic coverage and estimation method before comparing figures.
5. Prioritise reporting on detention and attacks against civilians in El Geneina, West Darfur, El Fasher and Zamzam, with particular attention to incidents following changes in territorial control.
6. Track UN Security Council action on a nationwide arms embargo and targeted sanctions, then assess whether any decision produces documented interdictions or route closures rather than treating diplomatic proposals as operational disruption.

Confidence & uncertainty

Overall confidence is high because the principal developments are supported by repeated reporting from the UN fact-finding mission, wire services and major-media accounts. The South Kordofan attacks, humanitarian pressures and external-support networks have multiple supporting reports. Confidence is lower for specific attribution of UAE involvement, the current status of Al-Kurmuk and Ed Damazin, the scale of total conflict deaths and the likelihood of another cross-border incident. The discrepancy over the exact release date of the UN report does not materially affect its reported findings.
