Sudan Conflict: Drone Warfare, External Support and Civilian Risk

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-09-06 22:09Z · Overall confidence: HIGH

BLUF

Civilian harm in Darfur and Kordofan is very likely to increase over the next 30 days as SAF, RSF and SPLM-N operations continue. The new UN findings strengthen the assessment that external personnel, weapons and logistics are sustaining the RSF, while allegations of an SAF chlorine-weapons programme add a contested but high-impact risk.

Executive summary

Recent reporting documents RSF drone strikes in Kalogi, SAF strikes in Ad-Da'ein and SPLM-N attacks in Debi, Luwairi and Dilling, confirming that civilians remain exposed across South Kordofan and Darfur. A UN fact-finding mission identified up to 2,000 former Colombian military contractors with the RSF and described supply routes through Chad, southeastern Libya and Bosaso. The UAE rejects allegations of state support to the RSF, leaving direct government responsibility unresolved. Investigative reporting and a US finding support allegations that the SAF developed and used chlorine munitions, but the SAF denies the allegations and the OPCW clarification process remains under way.

Change from previous assessment

Since the 5 September 2026 brief, the assessment has added a new, contested chemical-weapons judgment concerning the SAF and raised confidence in the persistence of external support networks because the UN findings now detail up to 2,000 former Colombian military contractors, transit routes and foreign-supplied systems. The civilian-harm judgment is now focused more sharply on recent drone strikes in Kalogi and Ad-Da'ein, alongside attacks in Debi, Luwairi and Dilling. The prior judgments on humanitarian deterioration and possible cross-border escalation remain, but confidence in cross-border escalation is lower because the current evidence remains thin and attribution is contested.

Key judgments

1. Additional civilian casualties in Sudan are very likely over the next 30 days, with the highest immediate risk in South Kordofan and East Darfur. The UN mission and major media reporting documented RSF drone strikes that killed 114 people, including about 60 children, in Kalogi and SAF strikes that killed at least 70 people and destroyed a hospital in Ad-Da'ein. Recent SPLM-N attacks in Debi, Luwairi and Dilling add a ground and artillery threat. Confidence is high because the main incidents are corroborated across multilateral, major-media and local reporting, although attribution and casualty totals for the South Kordofan attacks remain less settled. (Confidence: high · ASSESSED)

• I&W: Confirm: within 0-14 days, independently reported RSF, SAF or SPLM-N strikes in Kalogi, Ad-Da'ein, Debi, Luwairi or Dilling cause civilian casualties or damage medical infrastructure. (0-14 days)
• I&W: Break: within 0-14 days, local medical and major-media reporting records no new civilian casualties or casualty influxes from those five locations. (0-14 days)

2. RSF access to foreign personnel, weapons and logistics is very likely to remain available over the next 1-3 months, sustaining its use of advanced systems; SAF access to foreign-supplied drone capabilities is also likely to continue. The UN mission documented up to 2,000 former Colombian military contractors operating combat drones, artillery and advanced weapons with RSF units in Darfur and Kordofan, alongside routes through Chad, southeastern Libya and Bosaso. Reporting also identifies Chinese CH-95 drones with the RSF and Turkish and Iranian assistance linked to SAF drone capabilities. Confidence is high for the existence of external support networks, but lower for the role of specific governments. (Confidence: high · ASSESSED)

• I&W: Confirm: within 1-3 months, credible reporting identifies new foreign personnel, weapons deliveries or CH-95 operations with RSF units, or continued foreign-supplied drone use by the SAF. (1-3 months)
• I&W: Break: within 1-3 months, the UN or another reliable investigation documents closure of the identified transit routes and no new foreign personnel or weapons reaching the RSF. (1-3 months)

3. The direct responsibility of the UAE government for RSF support remains unresolved. The UN mission identified entities and intermediaries operating from the UAE among networks moving personnel, weapons, training and logistics to the RSF, while the UAE denies providing military, financial, political or logistical support and says it has not supplied weapons to any party since April 2023. Confidence is medium because the evidence supports UAE-linked networks but does not directly establish government direction or control, and the official denial is a material contradiction. (Confidence: medium · ASSESSED)

• I&W: Confirm: within 1-3 months, an official investigation identifies UAE government officials, state-controlled entities or official facilities directing or financing RSF transfers. (1-3 months)
• I&W: Break: within 1-3 months, the UN mission withdraws or materially qualifies its findings on UAE-linked networks and independent reporting finds no UAE-based facilitation. (1-3 months)

4. The SAF likely developed and stockpiled chlorine munitions by October 2024, but whether it used them remains unresolved. Investigative reporting describes a chlorine-weapons programme, nearly 300 manufactured munitions and up to 290 weapons stockpiled at Merowe, with 106 reportedly used; the United States has separately concluded that Sudan used chemical weapons. The SAF denies developing or using them, and the OPCW clarification process remains under way. Confidence is medium because the allegations are supported by multiple reports and a US finding, but the public evidence is limited and the attribution is directly contested. (Confidence: medium · ASSESSED)

• I&W: Confirm: within 0-3 months, the OPCW publishes findings or additional independent evidence corroborates chlorine-munition production, the Merowe stockpile or use by SAF units. (0-3 months)
• I&W: Break: within 0-3 months, the OPCW clarification process rejects the reported evidence and no independent source corroborates production or use. (0-3 months)

5. Humanitarian conditions in Darfur and Kordofan are very likely to worsen over the next 30 days. International organisations report more than 100,000 people facing displacement in the two regions, while around 21 million people across Sudan require food assistance. New attacks in South Kordofan, civilian flight from Debi and detention of civilians accused of supporting the SAF in West Darfur add to the pressure. Confidence is medium because the direction of travel is supported by recent reporting, but displacement and casualty estimates use different methods and dates. (Confidence: medium · ASSESSED)

• I&W: Confirm: within 0-30 days, new reporting records displacement from Debi, Luwairi, Dilling, Kalogi, Ad-Da'ein, El-Fasher or West Darfur above the current estimate of 100,000 people. (0-30 days)
• I&W: Break: within 0-30 days, humanitarian reporting records no new displacement from those locations and documents sustained access to food assistance for affected communities. (0-30 days)

6. 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 war remains unlikely. Reporting records US condemnation of SAF airstrikes inside Chad, a SAF-attributed drone strike near the Ethiopian border and unresolved allegations of support from Ethiopian territory. Confidence is low because the cross-border evidence is thin, relies substantially on local reporting and includes contested attribution. (Confidence: low · ASSESSED)

• I&W: Confirm: within 1-3 months, a new SAF strike on Chadian territory, a Chadian retaliatory action or a verified military incident near the Ethiopian border is reported. (1-3 months)
• I&W: Break: within 1-3 months, no new cross-border incident occurs and reliable reporting directly revises the attribution of the reported SAF strikes. (1-3 months)

Outlook & scenarios

Continued attritional fighting and civilian harm (70%)

SAF, RSF and SPLM-N continue fighting in Kordofan and Darfur through October 2026. Further drone and artillery attacks in Kalogi, Ad-Da'ein, Debi, Luwairi and Dilling produce civilian casualties, while RSF attacks continue to pressure essential infrastructure in El Obeid. This is the most likely path.

External support persists despite diplomatic pressure (55%)

Foreign personnel, weapons and logistics continue reaching the RSF through routes involving Chad, southeastern Libya and Bosaso, while foreign-supplied systems sustain SAF drone operations. UN, US and UAE calls for nationwide arms restrictions and targeted sanctions intensify, but the identified networks adapt rather than stop.

Limited cross-border spillover (30%)

An unlikely but plausible path is a new SAF incident in Chad or near the Ethiopian border that prompts diplomatic condemnation without producing a broader regional war. The conflict remains concentrated inside Sudan, but external support allegations continue to raise regional tensions.

Chemical-weapons evidence reaches a decisive threshold (15%)

A low-probability, high-impact wildcard is convergence between OPCW clarification, the US finding and additional evidence on SAF chlorine-munition production or use. Such a finding would place further pressure on the SAF and increase demands for international accountability.

Recommendations

1. Prioritise near-term collection on Kalogi, Ad-Da'ein, Debi, Luwairi, Dilling and El Obeid. Cross-check satellite imagery, local medical reporting, SAF and RSF statements, and multilateral reporting before revising casualty or attribution assessments.
2. Separate evidence of UAE-linked logistics from evidence of UAE government direction. Track official responses and investigative findings involving the UAE, Colombia, Chad, Libya, Somalia and Ethiopia.
3. Maintain a dedicated chemical-weapons watchlist covering Merowe, reported chlorine stockpiles, the OPCW clarification process, US sanctions activity and further SAF denials or admissions.
4. Use a consistent humanitarian baseline in future reporting. Distinguish the estimate of more than 100,000 people facing displacement in Darfur and Kordofan from the estimate of around 21 million people requiring food assistance across Sudan.
5. Flag any confirmed SAF strike on Chadian territory, Chadian retaliation or military activity near the Ethiopian border for immediate regional-risk review.

Confidence & uncertainty

Overall confidence is high because the principal developments are supported by a UN fact-finding mission, multilateral reporting, major media and local medical reporting, with repeated agreement on recent strikes, foreign support networks and humanitarian pressure. The main uncertainties concern direct UAE government responsibility, the final attribution and scale of the alleged SAF chemical-weapons use, inconsistent casualty and displacement estimates, and the limited evidence for future cross-border escalation.
