BLUF

Mali and Burkina Faso remain extreme‑risk operating environments, while credible OSINT on unexploded Russian‑made submunitions after Malian strikes raises legal exposure for Bamako and points to deepening Russian support. JNIM’s entrenchment in northern Benin, with mounting deaths and displacement, shows the insurgency’s southward reach; NASA VIIRS hotspots in Mali require corroboration and do not on their own evidence combat.

Executive summary

Official travel and aviation warnings depict Mali as a do‑not‑travel theatre with high threats from terrorism, kidnapping and violent crime, frequent protests, limited medical care, and U.S. personnel restricted to Bamako. NASA recorded 35 VIIRS thermal alerts over Mali on 23 June within a defined bounding box, but NASA itself notes such detections record heat, not cause. Bellingcat‑linked reporting geolocated unexploded Russian‑made ShOAB‑0.5 submunitions at Tadjmart after Malian Armed Forces announced strikes on 17 May; Mali is a Convention on Cluster Munitions signatory, and Russia’s Africa Corps is supporting Malian operations. In Burkina Faso, the insurgency that began in 2015 has featured mass‑casualty attacks in Ouagadougou and Yirgou and has displaced over two million people, alongside periodic large‑scale army operations. Southward pressure persists: JNIM controls parts of Benin’s W and Pendjari National Parks, eight Beninese soldiers were killed there in February 2022, and reporting cites 350+ killed and 35,000 displaced in northern Benin despite border defences. Strategically, Mali, Niger and Burkina Faso withdrew from ECOWAS on 28 January 2024 and established the Alliance of Sahel States on 6 July 2024, after Mali ended French defence accords in 2022 and Niger demanded French troop withdrawal in July 2023; reporting adds that AES cut military ties with Western powers in 2024 as U.S. presence diminished after the 2023 coup. Humanitarian outlooks warn that the Sahel faces sharpened drought risk amid five consecutive years of worsening food insecurity.

Change from previous assessment

New developments since the prior brief: NASA recorded 35 VIIRS hotspots over Mali on 23 June and reiterated that thermal alerts alone do not evidence combat; OSINT on unexploded Russian‑made ShOAB‑0.5 bomblets near Tadjmart remains salient in light of Malian strikes announced on 17 May and reported Russian Africa Corps support; and the coastal spillover picture is sharpened by corroborated reporting on JNIM control in Benin’s W and Pendjari parks with associated fatalities and displacement. The AES political trajectory is restated with timeline anchors on ECOWAS withdrawal, AES establishment, and the severing of Western defence ties. Core risk lines for Mali and Burkina Faso are unchanged. Initial assessment of this topic was issued previously; confidence levels are maintained.

Key judgments

1. Mali almost certainly remains an extreme‑risk operating environment this quarter, with a Do Not Travel advisory citing crime, terrorism and kidnapping, frequent demonstrations, FAA aviation warnings, limited medical care, and U.S. personnel barred from travel outside Bamako. (Confidence: high · ASSESSED)

• I&W: U.S. travel advisory for Mali remains at Do Not Travel or is tightened, and FAA extends or updates its Mali NOTAM. (0-3 months)
• I&W: U.S. mission in Bamako lifts the outside‑Bamako travel ban for official staff. (1-3 months)

2. It is very likely that Malian operations in northern Mali involved or left behind Russian‑made ShOAB‑0.5 submunitions near Tadjmart after strikes announced on 17 May, which would expose Bamako to legal and reputational risk as a Convention on Cluster Munitions signatory; Russia’s Africa Corps is supporting Malian forces. (Confidence: medium · ASSESSED)

• I&W: Additional geolocated imagery or physical documentation of ShOAB‑0.5 bomblets at sites south of Aguelhok linked to May air operations. (0-14 days)
• I&W: Authoritative technical assessment attributing the remnants to a non‑state cache accident rather than delivery by FAMa aircraft. (1-3 months)

3. Burkina Faso almost certainly remains a high‑threat theatre, reflected in a long‑running insurgency since 2015, mass‑casualty attacks in Ouagadougou and Yirgou, and over two million displaced, alongside periodic large‑scale counter‑operations by the Burkinabé Army. (Confidence: high · ASSESSED)

• I&W: Sustained reporting of complex attacks or high‑fatality incidents in Ouagadougou or key provincial centres. (1-3 months)
• I&W: Verified reductions in attack tempo and documented returns of internally displaced persons to origin communes. (3-6 months)

4. Militant pressure very likely continues to push south into Benin’s borderlands, with JNIM controlling parts of W and Pendjari National Parks and a death toll exceeding 350 and 35,000 displaced since late 2021, despite Benin’s border defence works. (Confidence: medium · ASSESSED)

• I&W: New JNIM attacks south of park confines or along the Alibori corridor with reported security‑force fatalities. (0-3 months)
• I&W: Documented dismantlement of militant positions and re‑opening of park zones to civilian movement under state control. (1-3 months)

5. The AES juntas are likely to entrench separation from Western security partners through 2026, given ECOWAS withdrawal on 28 January 2024, the AES’ establishment on 6 July 2024, Mali’s 2022 termination of defence accords with France, Niger’s July 2023 demand for French troop withdrawal, and reporting that the AES cut military ties with Western powers in 2024 as U.S. presence diminished after the 2023 coup. (Confidence: medium · ASSESSED)

• I&W: AES or national announcements rejecting renewed Western training, basing or joint operations. (1-6 months)
• I&W: Publicised agreements with France, the EU or the United States restoring military cooperation or basing rights. (1-6 months)

6. NASA FIRMS detections over Mali, including 35 VIIRS hotspots on 23 June with 14 high‑confidence alerts within 13.87,-4.79 to 18.87,0.21, almost certainly do not by themselves evidence combat activity and require independent corroboration. (Confidence: high · ASSESSED)

• I&W: Time‑and‑location matched ground reporting or official communiqués confirming strikes or clashes at specific hotspot coordinates. (0-14 days)
• I&W: Attribution of the same hotspots to wildfires or industrial activity by local authorities or credible observers. (0-14 days)

7. Humanitarian stress across the Sahel is likely to intensify seasonally this year, with five consecutive years of worsening food insecurity and FAO flagging the Sahel as among the sharpest drought‑risk zones. (Confidence: medium · ASSESSED)

• I&W: New UN or government reporting of IPC phase deterioration in Mali, Burkina Faso or Niger during the lean season. (1-3 months)
• I&W: Observed above‑normal rainfall and improved market access metrics lowering acute food insecurity classifications. (1-3 months)

Outlook & scenarios

Hardline AES alignment and insurgent resilience persist (60%)

Mali, Niger and Burkina Faso maintain distance from Western partners under the AES framework while insurgent violence endures in Burkina Faso and along key corridors. Mali’s operating environment stays extreme‑risk with sustained terrorism and kidnapping threats and continued movement and aviation restrictions. Burkina Faso experiences recurrent high‑fatality attacks and displacement pressures, with periodic army offensives failing to deliver durable security gains.

Coastal rim degradation centred on Benin’s parks belt (40%)

JNIM consolidates control nodes in W and Pendjari National Parks and extends activity south and east along Alibori, producing additional security‑force fatalities and displacement. Benin’s border defence works blunt but do not halt incursions, raising cross‑border friction with Burkina Faso and complicating humanitarian access.

Cluster‑munitions backlash constrains Bamako diplomatically (25%)

Further documentation of unexploded submunitions near Tadjmart linked to May air operations prompts intensified international scrutiny of Mali’s conduct as a Convention on Cluster Munitions signatory. Legal and reputational costs rise for Bamako, complicating external financing and narrow security cooperation, while Moscow’s embedded support to Malian forces deepens.

Recommendations

1. Treat Mali as non‑permissive. Defer non‑essential travel, enforce strict movement control in Bamako, and plan medical evacuation and alternate communications assuming limited local care and police response.
2. For any air operations planning or overflight near Mali, review current FAA notices and route around published risk areas. Maintain a real‑time aviation risk feed into ops rooms.
3. Use NASA FIRMS VIIRS hotspots as cues only. Corroborate with time‑matched local reporting, satellite imagery, and official communiqués before inferring combat activity.
4. Task OSINT and geospatial teams to archive, geolocate and chain‑of‑custody all imagery of submunitions in northern Mali. Prepare a legal brief on Convention on Cluster Munitions exposure for counterpart engagements with Malian authorities.
5. Prioritise monitoring of Benin’s W and Pendjari National Parks and the Alibori corridor for new JNIM incidents. Update route security matrices for teams transiting northern Benin and neighbouring Burkinabé border areas.
6. Maintain a live tracker of AES political and defence statements, especially on foreign training or basing. Flag any openings or reversals promptly to decision‑makers.
7. Pre‑position analytical coverage on drought and food insecurity indicators for Mali, Burkina Faso and Niger. Map likely lean‑season hotspots to inform contingency planning and partner outreach.

Confidence & uncertainty

Overall confidence is high because core judgments rest on multiple, mutually reinforcing official sources and reputable reporting: U.S. Department of State travel and risk advisories, FAA aviation notices, NASA FIRMS technical data and guidance, and UN‑linked and major‑media OSINT on conflict dynamics. Where assessments extend beyond direct reporting, such as legal exposure from submunitions findings or the trajectory of AES alignment, confidence is set to medium and explicitly caveated. Remaining uncertainties include battlefield attribution of specific thermal detections, the chain‑of‑custody and provenance of ordnance remnants in northern Mali, and the pace of AES policy shifts.

Alternative analysis (red cell)

On the cluster‑munitions allegation (judgment_index 1), while reports and a geolocation exist, the available evidence is primarily medium‑admiralty and lacks forensic linkage, chain‑of‑custody, and multiple independent corroborations tying the bomblets to the Malian May 17 strikes; therefore it is plausible the bomblets’ presence does not conclusively demonstrate Mali delivered Russian ShOAB‑0.5 submunitions. On Benin (judgment_index 3), documented attacks, casualties, and displacement show severe insecurity, but the dataset does not definitively establish durable territorial control by JNIM over parts of the parks — a cautious reading is that militants exert an operational presence producing episodic control rather than continuous governance.
