Sahel security crisis deepens as AES economic fallout grows

In Mali, Burkina Faso, and Niger, the pledge to reclaim security is colliding with a reality that is becoming harder to hide. A surge in jihadist attacks and setbacks suffered by national forces and their Russian partners are casting doubt on the effectiveness of the Alliance of Sahel States (AES) security strategy. In Mali, the assault on Dioura, followed by fresh operations against military positions, illustrates a threat that the Africa Corps’ presence has not managed to contain.

The economic and social consequences are becoming increasingly tangible. Trade routes are disrupted, markets are shrinking, and civilians are bearing the brunt of a conflict that shows no sign of abating. For businesses and households across the Sahel, the daily cost of insecurity is mounting.

The Dioura attack: a costly blow to Mali’s military and its partners

On September 10, the military camp at Dioura in central Mali was the target of a major offensive claimed by the Group for the Support of Islam and Muslims (JNIM), an Al-Qaeda affiliate. The death toll has risen sharply over the days. According to military, security, and local sources, at least 100 Malian soldiers and five members of the Russian Africa Corps were killed. Malian authorities have not released a final official figure. JNIM claims an even higher toll, with 150 dead and 93 prisoners—figures that cannot be independently verified.

The scale of the losses is not the only concern. Images released by the jihadist group suggest that a significant quantity of weapons, ammunition, and vehicles was seized at Dioura. The Malian army site was reportedly turned into a supply source for JNIM fighters. This ability to temporarily take control of a military position and seize its equipment highlights the difficulties Malian forces face on the ground.

Pressure mounts closer to Bamako

The Dioura affair is not an isolated episode. In the following days, JNIM stepped up operations against military installations in central Mali. Attacks targeted Konna and the Sévaré area, home to important Malian military infrastructure and Africa Corps elements.

In Sévaré, kamikaze drones specifically targeted the zone where Russian helicopters and Turkish Bayraktar armed drones are stationed. This attack is particularly symbolic: it struck infrastructure meant to contribute to the technological superiority of Malian forces and their Russian partners.

The threat is also reaching the outskirts of the capital. After several offensives against Malian positions in 2026, JNIM continues to demonstrate its ability to strike strategic axes and infrastructure near Bamako. This evolution matters: the challenge is no longer just defending remote rural areas, but also protecting the country’s main political, military, and economic centers.

Africa Corps: a rebrand with contested results

Since the withdrawal of French forces and the UN mission, Bamako has chosen to deepen its military partnership with Moscow. The Africa Corps, placed under the direct control of the Russian Ministry of Defense, has gradually taken over from Wagner in Mali. Its troop numbers are estimated by some sources at several thousand men.

This cooperation was supposed to strengthen the Malian authorities’ military capabilities, regain control of territory, and fight jihadist groups and armed movements more effectively. But recent events raise a central question: does the Russian presence actually improve the security situation?

The setbacks of 2026 provide at least grounds for debate. In April, a coordinated offensive by JNIM and the Azawad Liberation Front (FLA) already 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 highlighted the limits of the Africa Corps against a jihadist strategy based on mobility, attrition, and coordinated attacks.

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

A crisis that spills across Mali’s borders

The problem affects the entire AES. Burkina Faso and Niger are also facing persistent jihadist armed group activity. According to the Africa Center for Strategic Studies, violence linked to militant Islamist groups has reached particularly 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 the evolution of armed groups’ tactics and alliances poses 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 with the ambition of strengthening cooperation among its members on defense and security, thus faces a contradiction. While its leaders present their 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

The question of the Africa Corps’ effectiveness 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 multiplication of attacks against Malian forces shows that these means alone are not enough to reverse the conflict’s dynamics.

More worrying still, some operations attributed to the Africa Corps have sparked serious accusations regarding civilian populations. Human Rights Watch claims that airstrikes conducted 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.

In an asymmetric war, however, firepower is only one element of the response. Protecting populations, local intelligence, sustainable control of territories, securing roads, and the ability to prevent armed groups from reconstituting are just as decisive.

The AES security gamble under scrutiny

Dioura is therefore more than a tactical defeat. The attack comes after months of jihadist offensives and as Bamako heavily bets on its partnership with Moscow.

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

The Africa Corps’ presence has changed 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’s effectiveness will not be the number of weapons delivered, strikes carried out, or fighters reported neutralized. It will be measured by the states’ ability to durably protect their soldiers and populations, secure their territories, and prevent armed groups from regaining the initiative. On that front, recent events show the challenge remains whole.
