Reaching the capital once, and the garrisons repeatedly.
Tillabéri was the deadliest region of the central Sahel in 2025. Islamic State Sahel attacked Niamey's airport on 29 January 2026, its first operation in the capital, and in April 2026 mounted nine attacks on security forces that killed at least thirty-five personnel. The August 2026 mutineers included troops from Ouallam, Téra and Dosso. JNIM and Islamic State Sahel contest Tillabéri and Dosso between themselves. No attack on the Arlit road, the oil pipeline or a mining site has been identified in 2026, and the Benin border remains closed.
Latest reviewBaseline
Opened by the Watch & Activity monitoring expansion pass, which found Niger's own pressure system recorded as a campaign, two key events and a mutiny with no standing question. Baseline is the position after the August 2026 mutiny: one attack in the capital, sustained attacks on the western garrisons, no attack on the export infrastructure identified.
Why it matters
Niger's war is fought by a different organisation with a different object from Mali's, and reading it through the Malian questions hides both. The measure of Islamic State Sahel's pressure is not the death toll in Tillabéri, which the module holds at structural level, but where the attacks land: a garrison overrun and not reoccupied, a strike on the capital's approaches that recurs, or an attack on the uranium and oil infrastructure that pays for the state. The August mutiny showed the pressure reaching the capital by a second route — through the army's own losses — which is why this question and the regime-consolidation question name each other.
Observables7 named · “met” describes evidence, not success
01Test
An attack in the Niamey region
Any attack attributed to Islamic State Sahel or JNIM within the Niamey region, dated — the airport attack is the precedent; a second is the pattern.
02Test
A Tillabéri or Tahoua garrison overrun and not reoccupied
A base taken with its garrison withdrawn or destroyed, and whether the army returns to it within the month — the reach-to-hold distinction at garrison scale.
03Test
An attack on the oil pipeline, the Arlit road or a mining site
The pipeline to Benin, convoys on the Arlit road or a uranium site attacked — the observable that moves pressure onto the state's revenue.
04Test
A documented JNIM–Islamic State clash inside Niger
The two organisations fighting each other in Tillabéri or Dosso, reported by either's channels or by independent outlets — the seam that decides who holds the pressure.
05Test
Monthly attacks on security forces against the 2025 baseline
Event-data counts of attacks on military and security forces in western Niger, read monthly; a month above April 2026's nine is the marker, a week is not.
06Test
A further episode in the capital originating in the western garrisons
Mutiny, refusal or protest traced to Tillabéri units — the route by which the pressure reached Niamey in August, watched for recurrence and recorded in full on the regime question.
07Test
The Benin border and the pipeline's export status
Reopening, a documented export resumption or a further closure — read with the blockade question, which holds the corridor's economics.
What would change the assessment2 assessment-change conditions · qualitative, as the record states them
A second attack in the Niamey region, a garrison overrun and not reoccupied, or an attack on the pipeline or a mining site, any of which moves the pressure from the western regions onto the state's centre or its revenue.
A quarter without an attack on security forces above the 2025 monthly baseline together with a garrison reoccupied
Assessment effectmoves the reading from reaching to contained.
What remains unknown
- Attack counts rest on event data and armed-group claims; the Nigerien authorities publish casualty figures selectively and independent reporting from Tillabéri is thin.
- The status of the oil export pipeline and of the Arlit convoys is reported irregularly; an absence of reported attacks is a limit on visibility for the infrastructure observable.
Readings the evidence also supports
- The pressure is a JNIM–Islamic State contest for Tillabéri rather than a campaign against the state, in which case the clash observable is the leading one and the capital-approaches observable measures a side effect.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
