After Dioura, can the AES really turn the tide against jihadist insurgents?

The Sahel’s security landscape is shifting in ways that are hard to ignore. In Mali, Burkina Faso, and Niger, the promise of reclaiming territory from jihadist groups is colliding with a stark reality: attacks are multiplying, and the forces tasked with stopping them — including Russian partners — are struggling to deliver. The Dioura assault in central Mali, followed by fresh operations against military positions, raises a pressing question: does the Alliance of Sahel States (AES) have a viable path forward, or is it caught in a strategic dead end?

The Dioura attack and its aftermath

On September 10, the military camp at Dioura in central Mali was hit by a major offensive claimed by Jama’at Nusrat al-Islam wal-Muslimin (JNIM), an al-Qaeda affiliate. The death toll climbed in the days that followed. Military, security, and local sources indicated that at least 100 Malian soldiers and five members of Russia’s Africa Corps were killed. Malian authorities have not released an official figure. JNIM claimed an even higher toll — 150 dead and 93 captured — numbers that cannot be independently verified.

The scale of the losses is not the only concern. Images released by the jihadist group showed a substantial cache of weapons, ammunition, and vehicles seized at Dioura. The Malian army site was effectively turned into a supply source for JNIM fighters. This ability to temporarily overrun a military position and loot its equipment points to deeper difficulties facing Malian forces on the ground.

Pressure mounts near Bamako

Dioura is not an isolated incident. In the days that followed, JNIM stepped up operations against military installations in central Mali. Attacks targeted Konna and the Sévaré area, home to key Malian military infrastructure and Africa Corps personnel.

In Sévaré, kamikaze drones struck the zone where Russian helicopters and Turkish Bayraktar armed drones are stationed. The symbolism is hard to miss: the attack hit infrastructure meant to give Malian forces and their Russian partners a technological edge.

The threat is also creeping closer to the capital. After several offensives against Malian positions earlier in 2026, JNIM continues to show it can strike strategic routes and infrastructure near Bamako. This shift matters: the challenge is no longer just defending remote rural areas, but protecting the country’s main political, military, and economic centers.

Africa Corps: rebranding, but are results improving?

Since French forces and the UN mission withdrew, Bamako has deepened its military partnership with Moscow. The Africa Corps, under the direct control of Russia’s Ministry of Defense, has gradually taken over from Wagner in Mali. Its troop numbers are estimated by some sources at several thousand.

The cooperation was supposed to strengthen Malian military capacity, help retake territory, and fight jihadist groups and armed movements more effectively. But recent events raise a central question: is the Russian presence actually improving security?

The setbacks of 2026 offer at least grounds for debate. In April, a coordinated offensive by JNIM and the Azawad Liberation Front (FLA) struck several Malian towns and military positions. In July, an ambush near Anéfis inflicted further losses on Malian forces and their Russian partners. Analysts have since pointed to the limits of the Africa Corps against a jihadist strategy built on mobility, attrition, and coordinated attacks.

Dioura reinforces a question that goes beyond Mali: can a foreign force, even with air power and drones, compensate for the structural weaknesses of a national army facing an insurgency rooted in the territory?

A crisis that crosses borders

The problem affects the entire AES. Burkina Faso and Niger are also grappling with persistent activity by armed jihadist groups. According to the Africa Center for Strategic Studies, violence linked to militant Islamist groups has reached exceptionally high levels in the Sahel, with thousands of deaths recorded in recent years. JNIM alone accounts for a major share of deaths linked to militant violence in the region.

The Institute for Security Studies also estimates that evolving tactics and alliances among armed groups pose a growing challenge for Mali, Burkina Faso, and Niger. The organization calls for more concrete regional cooperation among the three countries.

The AES, created precisely to strengthen defense and security cooperation among its members, now faces a contradiction. While its leaders present the alliance as a sovereign response to the region’s security difficulties, jihadist groups continue to demonstrate their ability to exploit gaps in military arrangements.

Measuring effectiveness beyond firepower

Questioning the effectiveness of the Africa Corps does not mean Russian forces are incapable of conducting operations. They have aircraft, helicopters, drones, and intelligence capabilities that can inflict losses on armed groups. But the steady stream of attacks against Malian forces shows these assets alone are not enough to reverse the conflict’s momentum.

More troubling still, some operations attributed to the Africa Corps have sparked serious accusations regarding civilians. Human Rights Watch alleges that airstrikes in June in Kyrnia, in the Mopti region, killed eight civilians, including three children. The organization also accuses Africa Corps fighters of killing nine civilians in Bombori in July. These accusations are contested in their interpretation and must be placed in the context of operations against armed groups, but they fuel criticism of the methods used.

Yet in an asymmetric war, firepower is only one part of the response. Protecting populations, local intelligence, sustained territorial control, securing roads, and preventing armed groups from reconstituting are just as decisive.

The AES security gamble under scrutiny

Dioura is more than a tactical defeat. The attack comes after months of jihadist offensives and at a time when Bamako is heavily invested in its partnership with Moscow.

For AES governments, the challenge now is to prove their security model can deliver lasting results. But the succession of attacks in Mali, Burkina Faso, and Niger shows the jihadist threat remains deeply entrenched.

The Africa Corps has reshaped the AES military setup, but it has not eliminated the threat. In Mali, the attacks on Dioura, Sévaré, and areas near Bamako brutally remind of this reality.

The true measure of the AES security strategy will not be the number of weapons delivered, strikes carried out, or fighters announced as neutralized. It will be the ability of states to durably protect their soldiers and populations, secure their territories, and prevent armed groups from seizing the initiative. On that front, recent events show the challenge remains wide open.
