Sudan Conflict: Drone Warfare, External Support and Chemical Weapons Allegations

High
BOTTOM LINE

Civilian harm from RSF and SAF long-range drone operations is very likely to increase over the next 30 days, particularly in South Kordofan, North Kordofan and East Darfur. Foreign support networks are very likely to remain available to the RSF, while pressure for a nationwide arms embargo is likely to intensify but adoption is unlikely in the next 1-3 months.

KEY JUDGMENTS
  • Civilian casualties and infrastructure damage from RSF and SAF long-range drone operations are very likely to increase over the next 30 days, especially in Kalogi, South Kordofan, El Obeid, North Kordofan, and Ad-Da'ein, East Darfur. The reported RSF strikes in Kalogi killed 114 people, including about 60 children; SAF strikes in Ad-Da'ein killed at least 70 people and destroyed a major hospital; and repeated RSF attacks damaged vital infrastructure in El Obeid. (high)
  • Foreign support is very likely to remain available to the RSF over the next 1-3 months, while SAF access to foreign-supplied drone capabilities is likely to continue. Reporting identifies up to 2,000 former Colombian military contractors operating advanced weapons alongside RSF units in Darfur and Kordofan, networks using routes through Chad, southeastern Libya and Bosaso, and Chinese CH-95 drones for the RSF alongside Turkish Bayraktar Akıncı drones and YIHA-III loitering munitions for the SAF. The evidence identifies individuals, entities and networks operating from or through these locations, not direct UAE government direction, and the UAE denies providing support. (medium)
  • The SAF likely developed and stockpiled a chlorine-weapons programme by October 2024, but there is a roughly even chance that it used those weapons in attacks; the use allegation remains unresolved. Major-media investigations describe a July 2024 prototype test, nearly 300 manufactured munitions by October 2024 and a reported stockpile at Merowe, while the United States concluded that Sudan used chemical weapons. Sudan's military denies developing or using them, and a Sudanese investigative committee reported no evidence of contamination. The precise stockpile and use figures remain thinly corroborated. (medium)
  • US and UN-backed pressure to constrain arms flows and extend the Darfur arms embargo across Sudan is likely to intensify over the next 1-3 months, but adoption of a nationwide UN arms embargo is unlikely during that period. The United States is pressing for a resolution covering the whole country, the UN Fact-Finding Mission has urged the same extension, and the UK-led coalition has called for an end to external support. Russia rejected the US proposal in August, creating a direct obstacle to adoption. (medium)
  • Humanitarian conditions in Sudan, including North Darfur, South Kordofan, North Kordofan and Khartoum, are very likely to worsen over the next 30 days. UN reporting puts displacement above 11 million and acute food insecurity at around 20 million people, while other reporting places total displacement as high as about 14 million. The differing totals reduce confidence in the exact scale but do not materially change the assessment of continued deterioration. (high)

Sudan Conflict: Drone Warfare, External Support and Chemical Weapons Allegations

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-09-07 22:05Z · Overall confidence: HIGH

BLUF

Civilian harm from RSF and SAF long-range drone operations is very likely to increase over the next 30 days, particularly in South Kordofan, North Kordofan and East Darfur. Foreign support networks are very likely to remain available to the RSF, while pressure for a nationwide arms embargo is likely to intensify but adoption is unlikely in the next 1-3 months.

Executive summary

Current reporting documents severe civilian harm from RSF strikes in Kalogi, South Kordofan, which killed 114 people including about 60 children, and SAF strikes on Ad-Da'ein Teaching Hospital in East Darfur, which killed at least 70 people. Repeated RSF drone attacks have also damaged water, electricity and fuel infrastructure in El Obeid, North Kordofan. UN and official reporting attributes continued battlefield capability to foreign weapons, personnel and logistics networks, while new major-media investigations provide additional detail on an alleged SAF chlorine-weapons programme. The programme's development is better supported than claims that the SAF used the weapons, which remain directly contested by Sudan's military and an official investigative committee.

Change from previous assessment

Since the prior brief, new UN Fact-Finding Mission reporting strengthens the assessment that long-range drone warfare by both the RSF and SAF is extending civilian risk beyond traditional front lines. Confidence in continued civilian harm remains high. The chemical-weapons assessment is more detailed: confidence in SAF programme development is strengthened by the new dossier reporting, while confidence in actual use remains medium because Sudan's military and investigative committee continue to deny it. The current brief adds a judgment that pressure for a nationwide arms embargo is likely to intensify but that adoption is unlikely in the next 1-3 months. No prior judgment is retired.

Key judgments

  1. Civilian casualties and infrastructure damage from RSF and SAF long-range drone operations are very likely to increase over the next 30 days, especially in Kalogi, South Kordofan, El Obeid, North Kordofan, and Ad-Da'ein, East Darfur. The reported RSF strikes in Kalogi killed 114 people, including about 60 children; SAF strikes in Ad-Da'ein killed at least 70 people and destroyed a major hospital; and repeated RSF attacks damaged vital infrastructure in El Obeid. (Confidence: high · ASSESSED)
  • I&W: Confirmation: within 0-14 days, independently corroborated reporting records another RSF drone strike on civilian sites or water, energy or fuel infrastructure in Kalogi or El Obeid, or another SAF strike causing civilian deaths or hospital damage in Ad-Da'ein. (0-14 days)
  • I&W: Break: reporting records 14 consecutive days without a long-range RSF or SAF drone strike, new civilian casualties or additional infrastructure damage in the named locations. (0-14 days)
  1. Foreign support is very likely to remain available to the RSF over the next 1-3 months, while SAF access to foreign-supplied drone capabilities is likely to continue. Reporting identifies up to 2,000 former Colombian military contractors operating advanced weapons alongside RSF units in Darfur and Kordofan, networks using routes through Chad, southeastern Libya and Bosaso, and Chinese CH-95 drones for the RSF alongside Turkish Bayraktar Akıncı drones and YIHA-III loitering munitions for the SAF. The evidence identifies individuals, entities and networks operating from or through these locations, not direct UAE government direction, and the UAE denies providing support. (Confidence: medium · ASSESSED)
  • I&W: Confirmation: within 1-3 months, reporting identifies new foreign personnel, additional CH-95 or other advanced strike-drone activity, or renewed movement of weapons and supplies through Chad, southeastern Libya or Bosaso to RSF-held areas. (1-3 months)
  • I&W: Break: credible reporting documents sustained closure of the named transit routes and no new foreign personnel, weapons or drone systems reaching either force during the period. (1-3 months)
  1. The SAF likely developed and stockpiled a chlorine-weapons programme by October 2024, but there is a roughly even chance that it used those weapons in attacks; the use allegation remains unresolved. Major-media investigations describe a July 2024 prototype test, nearly 300 manufactured munitions by October 2024 and a reported stockpile at Merowe, while the United States concluded that Sudan used chemical weapons. Sudan's military denies developing or using them, and a Sudanese investigative committee reported no evidence of contamination. The precise stockpile and use figures remain thinly corroborated. (Confidence: medium · ASSESSED)
  • I&W: Confirmation: within 0-14 days, an independently verifiable forensic finding identifies chlorine residues in samples, victims or materials linked to the alleged chemical incident at Al Jaili in Bahri. (0-14 days)
  • I&W: Break: independently verifiable testing from the alleged incident produces no chlorine-related evidence and establishes a different cause for the reported breathing difficulties and deaths. (0-14 days)
  1. US and UN-backed pressure to constrain arms flows and extend the Darfur arms embargo across Sudan is likely to intensify over the next 1-3 months, but adoption of a nationwide UN arms embargo is unlikely during that period. The United States is pressing for a resolution covering the whole country, the UN Fact-Finding Mission has urged the same extension, and the UK-led coalition has called for an end to external support. Russia rejected the US proposal in August, creating a direct obstacle to adoption. (Confidence: medium · ASSESSED)
  • I&W: Confirmation: within 1-3 months, the United States or the UN Fact-Finding Mission sponsors a formal Security Council vote or a further public initiative to extend the embargo nationwide. (1-3 months)
  • I&W: Confirmation of continued blockage: Russia or another Security Council member publicly rejects or blocks a nationwide embargo proposal without an adopted resolution. (1-3 months)
  1. Humanitarian conditions in Sudan, including North Darfur, South Kordofan, North Kordofan and Khartoum, are very likely to worsen over the next 30 days. UN reporting puts displacement above 11 million and acute food insecurity at around 20 million people, while other reporting places total displacement as high as about 14 million. The differing totals reduce confidence in the exact scale but do not materially change the assessment of continued deterioration. (Confidence: high · ASSESSED)
  • I&W: Confirmation: within 0-14 days, UN or humanitarian reporting records additional displacement from North Darfur or South Kordofan, further damage to the Khartoum Teaching Hospital, Ophthalmology Hospital or Dental Hospital, or new access constraints in North Kordofan. (0-14 days)
  • I&W: Break: reporting records no additional displacement or hospital damage for 14 days and confirms restored access to essential services in the named locations. (0-14 days)

Outlook & scenarios

Attritional drone war and worsening civilian harm (55%)

The RSF continues strikes around Kalogi and El Obeid while the SAF continues long-range operations affecting East Darfur and other areas beyond traditional front lines. Civilian deaths, hospital damage and disruption to water, electricity and fuel supplies increase. External personnel and equipment remain available to both forces.

International pressure without an enforceable nationwide embargo (25%)

The United States, the UK and UN-linked investigators sustain public pressure for an arms embargo covering all of Sudan and for an end to external support. Russia or another Security Council member blocks progress, leaving the Darfur embargo in place without a nationwide measure.

Chemical-weapons dispute escalates (15%)

Further scrutiny of the alleged SAF chlorine programme, including the Merowe stockpile and the reported Al Jaili incident, increases pressure for accountability. The United States maintains its conclusion that chemical weapons were used, while Sudan's military and its investigative committee continue to deny the allegation.

Cross-border escalation involving Chad (5%)

A further incident linked to SAF activity near Chad or to RSF support routes through neighbouring territory produces a sharper interstate dispute. The episode disrupts existing movement and supply networks and widens the conflict's diplomatic consequences.

Recommendations

  1. Prioritise daily geolocated monitoring of RSF and SAF drone activity around Kalogi, El Obeid and Ad-Da'ein. Record civilian casualties, hospital damage and effects on water, electricity and fuel infrastructure in a single incident ledger.
  2. Maintain separate attribution lines for UAE-linked individuals and entities, Colombia-based networks and the governments of those countries. Track personnel, weapons and supplies moving through Chad, southeastern Libya and Bosaso without treating network activity as proof of direct government direction.
  3. Assess the chemical-weapons issue on two tracks: treat SAF programme development as the stronger finding, while keeping alleged use unresolved until independent physical or forensic evidence is available. Preserve the distinction between the US conclusion, major-media investigations, Sudan's denial and the Sudanese committee's finding.
  4. Monitor the UN Security Council process for a nationwide arms embargo, including formal sponsorship, voting steps and further Russian opposition. Prepare reporting that distinguishes a US proposal, UN Fact-Finding Mission advocacy and any adopted measure.
  5. Use the UN displacement and food-insecurity figures as the primary humanitarian baseline, while retaining the reported higher displacement estimate as an uncertainty range. Prioritise early warning for additional displacement from North Darfur and South Kordofan and further damage to the three named Khartoum hospitals.

Confidence & uncertainty

Overall confidence is high because the central findings are corroborated by UN and other multilateral reporting, official government statements, and multiple major-media investigations. The RSF and SAF drone attacks, civilian harm, displacement and foreign support networks are supported by more than one reliable source stream. The main uncertainties concern the exact displacement total, the extent of direct UAE government involvement, the precise scale of the SAF chemical-weapons programme and whether the SAF used chlorine weapons.
