The Sahel Under Pressure: Jihadist Escalation and Security Restructuring in West Africa (March 2026)

West Africa is going through an unprecedented period of security turbulence. The first months of 2026 have highlighted a qualitative and quantitative evolution of the threats posed by jihadist armed groups, while regional security architectures are under considerable centrifugal pressures. Between the Alliance of Sahel States (AES), which is consolidating its sovereignist bloc, and ECOWAS, which is trying to reactivate its collective defense mechanisms, the future of the entire sub-region is at stake across several simultaneous theaters.

The attack on January 29, 2026, against the Dori Hamani International Airport in Niamey is undoubtedly the most symbolic event of this escalation. About thirty fighters from the Islamic State Sahel Province (ISSP) launched a coordinated assault using armed drones, light weapons, and mortars against this critical infrastructure, which houses both Nigerien military drone operations and the AES headquarters. The attack, lasting two hours, was ultimately repelled — all assailants were killed or captured — but its symbolic impact is considerable. As highlighted by analysts from African Security Analysis, the assault represents a notable operational escalation by the ISSP, aimed not only at neutralizing military capabilities but also at demonstrating the vulnerability of state power centers.

In Burkina Faso, the situation is deteriorating in a particularly alarming manner. According to the SITE Intelligence group, JNIM (Jamaat Nusrat al-Islam wal-Muslimin, affiliated with Al-Qaeda) conducted over 500 attacks on Burkinabè territory during the year 2025 alone. In February 2026, a series of coordinated offensives was launched across the eastern and northern regions, illustrating the group's ability to move quickly over vast territories. The deadliest attack in this sequence occurred in mid-February in the commune of Titao, in the Northern region, where 80 soldiers and members of the supporting militias — the Volunteers for the Defense of the Homeland (VDP) — were killed. It is now estimated that armed groups control or contest up to 60% of Burkinabè territory, gradually encircling the capital Ouagadougou. The mobility of security forces is seriously hindered by improvised explosive devices (IEDs) and nighttime ambushes on logistical routes.

In Mali, JNIM launched an unprecedented economic siege operation in September 2025 by systematically intercepting fuel convoys coming from Côte d'Ivoire and Senegal. At the height of the crisis, a dozen fuel trucks were set on fire in a single day at the Senegalese border. The resulting fuel shortage partially paralyzed the capital Bamako for several months, affecting transportation, generators, and essential services. At the beginning of 2026, JNIM loosened its grip without any official explanation — a tactical decision that leaves observers perplexed and can be interpreted as a deliberate show of strength: the group proved it could suffocate a capital and chooses sovereignly when to relieve the pressure.

In terms of alliances and strategic partnerships, the Sahelian landscape has profoundly evolved since the break between the military juntas of Mali, Burkina Faso, and Niger with ECOWAS in January 2025. About 2,000 fighters from the Russian Africa Corps — a structure inherited from the Wagner group, now formally integrated into the Russian state apparatus — are deployed in these three countries. This Russian presence partially replaces the unraveled Western partnerships but has so far not demonstrated its ability to reverse the jihadist dynamic. Operations by the Malian Armed Forces (FAMa) and the Africa Corps have indeed eliminated more than 100 fighters between February 21 and March 6, 2026, according to official reports, but these tactical gains struggle to translate into measurable strategic progress.

In the face of this degradation, ECOWAS decided during a meeting of chiefs of staff in Freetown (Sierra Leone) to activate the mechanism of its Standby Force (ESF, ECOWAS Standby Force). The plan provides for the initial deployment of 2,000 soldiers by the end of 2026 to contain the expansion of armed groups, which now threaten coastal states. Indeed, JNIM attacked two military posts in Benin at the border with Burkina Faso during the February-March 2026 period — a first that clearly signals the geographical extension of the threat towards the Gulf of Guinea. Togo and Benin are under increasing pressure, with their northern regions serving as transit and recruitment zones for insurgents.

However, two major obstacles compromise the effectiveness of the ECOWAS mechanism. On one hand, funding remains problematic: the exit of the three AES countries from ECOWAS has reduced the budgetary contributions of the bloc. On the other hand, the political dimension of the crisis — the diplomatic break between coastal states and Sahelian juntas — complicates any operational coordination. States like Senegal and Ghana are playing a mediating role and have appointed special envoys, but the military leaders of the AES have so far ignored these openings. The Global Terrorism Index places the Sahel as the epicenter of global terrorism for the third consecutive year, and essential mechanisms such as cross-border pursuit rights, intelligence sharing, or combating illicit financing remain blocked by political disputes.

The increasing use of drones by jihadist groups may be the most concerning factor for Sahelian military staffs. The attack in Niamey demonstrated that the ISSP now possesses asymmetric aerial capabilities, albeit rudimentary, but sufficient to threaten protected infrastructures. During a confrontation in March 2026 in Burkina Faso, fighters seized a drone belonging to pro-Al-Qaeda militants — a sign that these technologies circulate freely among rival actors. A report from Al Jazeera in February 2026 documented how these low-cost, high-impact drones significantly complicate conventional counter-insurgency strategies. Responding to this emerging aerial threat would require significant investments in electronic warfare and anti-drone systems — capabilities that Sahelian armies are currently largely lacking.

In conclusion, the security trajectory of the Sahel in the first quarter of 2026 outlines a scenario of structural degradation that military operations alone cannot reverse. Jihadist pressure is simultaneously intensifying on several capitals, armed groups are refining their hybrid tactics, and the fragmentation of the regional security architecture leaves critical unprotected spaces. A truly effective response would require, as highlighted by Beverly Ochieng of Control Risks, not only a military response but a comprehensive operation integrating social interventions to curb the influence of these groups and their recruitment capacity. In the absence of such an integrated approach, the civilian populations of the Sahel continue to pay the heaviest price for a crisis whose resolution still seems distant.
