BLUF

SAF and RSF long-range drone attacks are very likely to continue across Kordofan, Blue Nile and Darfur over the next 30 days, while humanitarian conditions are very likely to worsen as IOM supplies approach depletion at the end of September and WFP warns of near-term scale-back. Ground control remains contested: the SAF reports reopened approaches to El Obeid and plans to target five Darfur cities, while the RSF and SPLM-N report gains in Blue Nile and the RSF surrounds El Obeid.

Executive summary

The conflict remains active across Darfur, Kordofan and Blue Nile. The UN fact-finding mission reports that both the SAF and RSF are expanding long-range drone use beyond traditional front lines, with recent strikes displacing thousands in Blue Nile, North Darfur and West Darfur. The SAF is signalling an offensive towards El Fasher, Ed Daein, Nyala, El Geneina and Zalingei, but RSF and SPLM-N advances in Blue Nile and the RSF's encirclement of El Obeid present competing battlefield trends. Humanitarian agencies warn of acute funding and supply failures, while diplomatic pressure is increasing around accountability and a proposed nationwide arms embargo.

Change from previous assessment

Since the 14 September brief, the assessment adds reported RSF and SPLM-N gains in Blue Nile, RSF drone attacks across Ed Damazin, and the SAF's stated reopening of routes towards Al-Rahad, Dilling and Kadougli. Confidence in continued drone activity and humanitarian deterioration remains high, while the near-term humanitarian warning has sharpened because IOM now places supply depletion at the end of September and WFP warns of scale-back within weeks. The assessment of a SAF advance towards the major Darfur cities remains medium confidence because the principal operational claims still lack independent confirmation. The nationwide embargo assessment remains unlikely before 9 October, and the chlorine-weapons assessment remains low confidence.

Key judgments

1. SAF and RSF long-range drone operations are very likely to continue over the next 30 days, keeping civilians and infrastructure exposed in Kalogie, El Obeid, Ed Damazin, Blue Nile, North Darfur and West Darfur. The UN fact-finding mission documents increasing use by both forces beyond traditional front lines. Recent reporting attributes 114 deaths, including 60 children, to RSF strikes in Kalogie, at least 70 deaths to SAF attacks on Ad-Da'ein Teaching Hospital, and repeated RSF damage to water and energy infrastructure in El Obeid. (Confidence: high · ASSESSED)

• I&W: Confirmation: independently corroborated SAF or RSF drone strikes are reported in Kalogie, El Obeid, Ed Damazin, Blue Nile, North Darfur or West Darfur. (0-14 days)
• I&W: Break: no independently corroborated long-range drone strike by either force occurs for 14 consecutive days, accompanied by evidence of a sustained operational halt. (0-14 days)

2. Ground fighting around El Obeid, Blue Nile and the approaches to Darfur is likely to intensify over the next 1-3 months, but there is a roughly even chance that the SAF enters any of the five named Darfur cities. Yasser Al-Atta states that the SAF has reopened routes through Al-Rahad, Dilling and Kadougli and will soon target El Fasher, Ed Daein, Nyala, El Geneina and Zalingei. In contrast, the RSF and SPLM-N report capturing Madal Abiqo, Beli Bong and Kambarda in Blue Nile and moving towards Ed Damazin, while the RSF surrounds El Obeid. The SAF's operational claims lack independent confirmation. (Confidence: medium · ASSESSED)

• I&W: Confirmation: independently verified SAF ground movement beyond Al-Rahad, Dilling or Kadougli towards El Fasher, Ed Daein, Nyala, El Geneina or Zalingei is reported. (0-3 months)
• I&W: Break: the RSF and SPLM-N retain their reported Blue Nile gains, the RSF maintains pressure on El Obeid, and no independently confirmed SAF advance towards a named Darfur city occurs. (0-3 months)

3. Humanitarian conditions are very likely to worsen across Kordofan and Darfur over the next 30 days. IOM warns that shelter, sanitation and emergency household supplies will run out by the end of September, WFP warns of operational scale-back within weeks, and aid in Tawila is limited to half rations despite reaching nearly the entire displaced population. More than 665,000 displaced people at Daba Naira camp in Tawila face famine, shelter shortages and diseases including cholera. The direction of deterioration is strongly corroborated, although displacement totals vary between approximately 8.6 million internally displaced, more than six million internally displaced and roughly 14 million displaced overall. (Confidence: high · ASSESSED)

• I&W: Confirmation: IOM reports depletion of shelter, sanitation or household relief stocks by the end of September, or WFP announces reduced rations or a reduction in coverage. (0-30 days)
• I&W: Break: new funding and access keep WFP assistance at roughly 4 to 5 million people per month and prevent the reported end-September IOM supply shortfall. (0-30 days)

4. International pressure on the SAF and RSF is very likely to intensify, while a nationwide UN arms embargo covering both forces before 9 October is unlikely. The UN fact-finding mission has found reasonable grounds to believe that both sides committed serious violations that may amount to war crimes. The United States is pressing to extend the embargo across Sudan, but the reported vote arithmetic remains contested and opposition from the A3, China, Pakistan and Russia is documented. The exact timing of the sanctions vote is also unresolved between reporting that places it on 11 September and reporting that places it on 14 September. (Confidence: medium · ASSESSED)

• I&W: Confirmation: the UN Security Council formally tables or adopts an embargo covering all Sudanese territory and both the SAF and RSF before 9 October. (0-30 days)
• I&W: Break: the Council records only a technical extension of the Darfur measures to 9 October and no confirmed support for expanding the embargo nationwide. (0-30 days)

5. RSF cross-border support networks are likely to remain available over the next 1-3 months, but direct UAE state responsibility remains unproven. UN investigators report support from individuals and entities in the UAE, Chad, southeastern Libya and Puntland, while other reporting identifies wider alleged support networks involving Ethiopia, Eritrea, Colombia and Somalia. The UAE denies arming the RSF, and claims that RSF drones launched from Assosa and other Ethiopian airfields remain single-source reporting. (Confidence: medium · ASSESSED)

• I&W: Confirmation: independently corroborated imagery, logistics reporting or official records link RSF drone activity or vehicle movements to Assosa, Chad, southeastern Libya, Puntland or UAE-linked entities. (1-3 months)
• I&W: Break: credible reporting documents interruption of the named support routes and no new independently corroborated evidence of external assistance reaches the RSF. (1-3 months)

6. There is a roughly even chance that the leaked records describe a genuine SAF chlorine-munitions programme, but the supplied reporting does not independently establish production, stockpiling or use. The New York Times and Washington Post report documents alleging that the SAF built, tested, stockpiled about 300 chlorine bombs and used them at Garri base and the Jaili refinery in 2024. Separate reporting describes plans to obtain chlorine from a civilian water-treatment facility, while the SAF denies developing or using chemical weapons. This judgment rests on conflicting and partly single-source reporting and therefore carries low confidence. (Confidence: low · ASSESSED)

• I&W: Confirmation: independent authentication of the leaked records is accompanied by forensic or physical evidence of chlorine munitions at Garri base or the Jaili refinery. (0-3 months)
• I&W: Break: forensic or document review invalidates the records or establishes that the reported chlorine was limited to civilian water-treatment use without weaponisation. (0-3 months)

Outlook & scenarios

Protracted drone warfare and aid contraction (55%)

This is the likely path over the next 30 days. SAF and RSF drone strikes continue across Kordofan, Blue Nile and Darfur, while IOM relief stocks approach depletion and WFP reduces coverage or rations. El Obeid, Tawila and displaced populations in North and West Darfur face the greatest immediate pressure.

SAF westward pressure, contained by RSF and SPLM-N resistance (25%)

The SAF sustains movement through Al-Rahad, Dilling and Kadougli and increases pressure towards El Fasher, Ed Daein, Nyala, El Geneina and Zalingei. The RSF retains its encirclement of El Obeid, while the RSF and SPLM-N hold Blue Nile gains and contest movement towards Ed Damazin. The result is a wider front without a confirmed SAF breakthrough into the major Darfur cities.

Diplomatic containment without a nationwide embargo (15%)

The UN Security Council maintains a short technical sanctions rollover centred on Darfur, while the United States, the UK, UN officials and other governments continue accountability and ceasefire pressure. The SAF and RSF continue fighting despite calls for an immediate ceasefire.

Verified chemical-weapons use or programme (5%)

Independent authentication of the chlorine records and physical evidence from Garri or the Jaili refinery confirms the SAF allegation. This would sharply raise accountability pressure and humanitarian protection concerns, while the broader battlefield remains active.

Recommendations

1. Prioritise collection on drone activity in Kalogie, El Obeid, Ed Damazin, Blue Nile, North Darfur and West Darfur over the next 14 days. Separate confirmed attribution from claims based only on local reporting.
2. Track the Al-Rahad, Dilling and Kadougli route, the approaches to El Obeid and the SAF's stated objectives of El Fasher, Ed Daein, Nyala, El Geneina and Zalingei. Treat statements from Yasser Al-Atta as operational intent until independently verified.
3. Use the end of September as the main humanitarian warning date. Monitor IOM stocks, WFP ration levels and access at Tawila and Daba Naira, and update planning assumptions if WFP reduces its 4 to 5 million monthly reach.
4. Verify the UN Security Council record and distinguish the one-month Darfur rollover from the proposed nationwide embargo. Monitor confirmed vote commitments rather than relying on reported assessments of member intentions.
5. Maintain a dedicated collection requirement on RSF external support routes through Chad, southeastern Libya, Puntland, UAE-linked networks and Assosa. Do not treat alleged UAE state responsibility as established without independent corroboration.
6. Keep the SAF chlorine allegation at low confidence. Seek independent authentication of the leaked records and separate evidence of a programme from evidence of actual production, stockpiling or use.

Confidence & uncertainty

Overall confidence is high for the broad assessment because UN, official government, major media and humanitarian reporting independently corroborate the expansion of drone warfare, civilian harm, battlefield activity and humanitarian strain. The main uncertainties concern attribution of some strikes, the reliability of SAF operational claims, inconsistent displacement totals, the outcome and timing of a nationwide arms embargo vote, alleged foreign support routes and the unresolved chlorine-weapons allegations.
