The coordinated offensive of April 25 in Mali: when insurgents rewrite the rules of the Sahelian game

On April 25, 2026, Mali was struck by a wave of simultaneous attacks of unprecedented recent scale, jointly carried out by jihadist groups affiliated with Al-Qaeda and separatist Tuareg rebels. These coordinated strikes, which reportedly resulted in the death of the Malian Minister of Defense according to the New York Times, are not just another episode in a conflict that has lasted over a decade. They reveal a profound transformation in the nature of the insurgency in the Sahel, a strategic mutation that redefines the parameters of regional security as a whole.

For a long time, the counter-insurgency strategy in Mali was based on a fundamental assumption: the fragmentation of armed groups. The northern Tuareg separatists pursued territorial objectives linked to their identity and historical grievances, while jihadist factions followed transnational ideological goals. These differences, far from being superficial, created real frictions between the groups, which sometimes clashed directly for control of territories, resources, and local influence. This structural division provided the Malian state and its international partners — notably France with Operation Barkhane and the G5 Sahel Joint Force — an opportunity to exploit. The strategy was to combine targeted military pressure with efforts to deepen internal rivalries, encourage defections, and arm local militias.

What occurred on April 25 suggests that this dynamic has radically changed. The insurgent groups demonstrated an unprecedented pragmatism, capable of overcoming their ideological differences to strike together at a common enemy: the Malian state. This is not a formal alliance or a doctrinal unification, but rather a flexible operational coordination, where simultaneous attacks on multiple fronts — using mobile units to evade military responses and relying on local intelligence — allowed for a multiplication of the strategic effect beyond what each group could have achieved alone. This evolution is all the more concerning as it occurs in a context of weakening state capabilities, with its effective presence diminishing in vast portions of the national territory.

The scope of this attack far exceeds the Malian framework. The assassination of a sitting Minister of Defense constitutes a blow to both the operational command capabilities and the psychological legitimacy of the ruling junta. The message is clear: the insurgents are no longer limited to peripheral areas; they can reach the highest echelons of the state's security apparatus. In a country governed by a military regime resulting from a coup d'état, whose legitimacy rests precisely on the promise of restoring security, such a failure strikes a severe blow to the implicit social contract between the ruling military and the population.

It is important to place these events in the broader context of the geopolitical reconfiguration of the Sahel. The Alliance of Sahel States (AES), formed by Mali, Burkina Faso, and Niger after their withdrawal from ECOWAS on January 29, 2025, launched in December 2025 a Unified Force initially comprising 5,000 personnel, increased to 6,000 in February 2026 and placed under the command of Burkinabè General Daouda Traoré, with headquarters in Niamey. Unlike the defunct G5 Sahel Joint Force, whose battalions were confined to designated geographical sectors with a right of pursuit limited to a radius of 100 kilometers on either side of the borders, the AES force has full operational authority over all three territories, allowing it to deploy and move troops without prior approval from national staffs. Funding relies on national mechanisms — Burkina Faso's Patriotic Support Fund, Niger's Homeland Safeguard Solidarity Fund, and Mali's Basic Infrastructure Support Fund — rather than on Western donors, a major structural difference aimed at preserving the strategic autonomy of the three juntas.

However, the expected results have yet to materialize. Violence has actually increased in the three countries since they came under military control between 2022 and 2023. Burkina Faso, ranked as the most affected country in the world by terrorism according to the latest Global Terrorism Index, illustrates this paradoxical dynamic: since Captain Ibrahim Traoré came to power in 2022, terrorist groups have killed approximately 87% more civilians than in the three previous years, and operate with relative freedom over up to 80% of the territory. Government forces, for their part, are reported to have killed up to 132% more civilians than before, according to a report by the Atlantic Council published in February 2026. In Niger, the ISSP carried out an attack on Niamey airport — the capital where the AES force is headquartered — on January 29, using drones for the first time in the country, according to ACLED. In Mali, JNIM has maintained a blockade of fuel supplies on Bamako for several months, economically suffocating the capital.

Meanwhile, ECOWAS continues its own security ambitions. The organization announced the deployment in 2026 of a Rapid Deployment Force of 1,650 personnel, the first component of a 5,000-strong ECOWAS Standby Force, which also serves as a West African brigade for the African Union Standby Force. The logistical depot in Lungi, Sierra Leone, estimated to be over 90% operational, is the centerpiece of this architecture. The planned integration of artificial intelligence and ISR drones for predictive analysis of insurgent movements reflects a desire for modernization. The projected annual budget of $2.5 billion relies on a self-financing model promoted by Nigerian President Bola Tinubu, requiring member states to prioritize the allocation of internal resources before seeking external partnerships.

Nevertheless, significant obstacles remain. A previous regional counter-terrorism strategy adopted in 2013 remained a dead letter due to lack of funding and political will. The specific financial commitments of member states remain inconsistent, with some preferring to fund national initiatives rather than contribute to a regional common pot. Most importantly, the split between the AES and ECOWAS creates an institutional duality that fragments the West African security response at a time when coordination is most needed.

The confrontation between these two parallel architectures — the AES Unified Force on one side, the ECOWAS RDF on the other — risks opening security vacuums that armed groups will exploit. The insurgents' ability to coordinate their actions across borders, as demonstrated by the April 25 offensive, starkly contrasts with the institutional division of the states attempting to combat them. Illicit supply networks for weapons, motorcycles, fuel, and drones cross multiple borders, as highlighted by analysts from the Institute for Security Studies, making any strictly national or structurally fragmented response inadequate.

The humanitarian situation continues to deteriorate. Massive displacements of civilian populations, limited access to food, healthcare, and education, and the growing vulnerability of rural communities create the exact conditions that fuel recruitment by armed groups. Instability in the Sahel is no longer just a regional issue: it affects global trade routes, migration patterns, and geopolitical dynamics on a global scale.

What is at stake in Mali today goes beyond the framework of a national conflict. It is a competition between two visions of regional security — one driven by sovereignist juntas supported by non-Western partnerships, the other by a regional organization seeking to maintain a collective architecture — against an adversary that has understood that pragmatic coordination takes precedence over ideology. As long as this lesson is not internalized by the states in the region, the initiative will remain with the insurgents.
