The Sahel Facing an Unprecedented Terrorist Escalation: The Alliance of Sahel States Confronted with Its Strategic Limits

The bold attack on Diori Hamani International Airport in Niamey on January 29, 2026, marks a worrying turning point in the security dynamics of the central Sahel. Thirty fighters from the Islamic State Province in the Sahel (ISSP) carried out a coordinated assault for two hours against the strategic infrastructure that houses both Nigerien military drone operations and the headquarters of the Sahel States Alliance (AES). While all assailants were neutralized, the attack achieved its main objective: to demonstrate that terrorist groups remain capable of striking at the very heart of Sahelian capitals, despite the intensification of counter-terrorism operations.

This nighttime offensive against Niamey is part of a sequence of terrorist escalation that deeply questions the promises made by the military juntas in power in Bamako, Ouagadougou, and Niamey. Since their rise to power through successive coups between 2020 and 2023, these regimes have justified their legitimacy by their supposed ability to suppress the jihadist insurgency where their democratic predecessors had failed. However, the facts testify to a very different reality: the terrorist threat has never been as geographically extensive or as bold in its operational methods.

In Mali, the capital Bamako lived for three months, between September 2025 and early 2026, under the grip of a fuel supply blockade orchestrated by Jama'at Nusrat al-Islam wal-Muslimin (JNIM), the Al-Qaeda-affiliated organization that remains the most structured jihadist actor in the region. JNIM fighters systematically intercepted and burned fuel convoys coming from Côte d'Ivoire and Senegal, paralyzing the Malian economy and sowing panic among the capital's population. In a particularly spectacular incident, a dozen tankers coming from Senegal were reduced to ashes. While the group mysteriously eased its blockade in early 2026 without official explanation, the psychological impact remains profound. "And tomorrow?" wonders Aissata, an employee at a supermarket in Bamako. "What will happen if the blockade returns or if the terrorist group decides to attack the market or any infrastructure in the city?"

The situation in Burkina Faso presents an even more alarming picture. According to the SITE Intelligence Group, JNIM conducted over 500 attacks there in 2025, consolidating its grip on nearly 60% of the national territory. The capital Ouagadougou thus finds itself de facto surrounded by jihadist influence zones. In the Central-North, East, and Sahel regions, nighttime attacks on military supply lines and the systematic use of improvised explosive devices have forced the armed forces and the Volunteers for the Defense of the Homeland (VDP) militias to retreat into a restricted defensive perimeter around their bases. This attrition strategy bore fruit in February 2026 in Titao, in the north of the country, where JNIM launched a deadly attack killing 80 soldiers and militia members as well as at least 20 civilians. The assailants simultaneously targeted a military camp, a local market, and the communication infrastructure in the area.

In the face of this deteriorating security situation, the Sahel States Alliance, created in September 2023 as a mutual defense pact before transforming into a confederation in July 2024, struggles to demonstrate its operational effectiveness. In January 2026, the AES officially commissioned a joint military force of 5,000 men intended to conduct cross-border operations against terrorist groups. This initiative comes after the de facto collapse of the G5 Sahel, a regional mechanism that benefited from significant French support, and the withdrawal of the three countries from the Economic Community of West African States (ECOWAS).

However, analysts remain skeptical about this force's ability to reverse the trend. "The juntas seem to have no response to the terrorist expansion, just like their counterparts in Niger and Burkina Faso," confides a lecturer at the University of Legal and Political Sciences in Bamako, who requested anonymity for fear of reprisals. The Malian armed forces are stretched to the extreme by persistent terrorist attacks and weakened by defections to JNIM, a phenomenon that reflects the erosion of state legitimacy in rural areas.

The geopolitical realignment undertaken by the three Sahelian juntas further complicates the security equation. After breaking their military partnerships with Western powers and expelling the French forces conducting Operation Barkhane, Bamako, Ouagadougou, and Niamey have turned to Russia. Mercenaries from the Wagner Group, now renamed "Africa Corps" under more direct Russian state control, have replaced Western contingents. However, human rights defense organizations and researchers specializing in the Sahel report a troubling continuity: the same joint operations with national armed forces, similar patterns of disappearances and executions of civilians, and an opaque use of military bases and equipment.

At the same time, ECOWAS is trying to maintain its relevance in a fragmented regional landscape. The ECOWAS Commissioner for Political Affairs, Peace, and Security, Abdel-Fatau Musah, announced in September 2025 the deployment in 2026 of a Rapid Deployment Force of 1,650 personnel. While this initiative is symbolically welcome, it appears largely insufficient to reverse the short-term insecurity dynamic, especially as ECOWAS faces a chronic lack of dedicated financial resources.

The strategic analysis of JNIM reveals an organization that deliberately prioritizes institutional attrition over episodic escalation. Its operations aim to degrade state mobility, erode local security architectures, and exert sustained pressure on economically and politically significant corridors. This approach, aligned with Al-Qaeda's regional doctrine, prioritizes longevity, local anchoring, and political relevance over spectacular mass attacks. The constant use of propaganda in local languages and the rapid attribution of claims reinforce its posture as a durable insurgent actor seeking to normalize its de facto authority and compel populations to cope with its presence.

Despite their extensive control over the Burkinabè countryside, terrorist groups lack the manpower and firepower necessary to conquer Ouagadougou, according to analysts Djiby Sow and Hassan Koné from the South African Institute of Strategic Studies. However, this tactical assessment obscures the fundamental strategic question: to what extent can a state maintain its sovereignty when it controls only 40% of its territory?

The Sahel is undergoing a profound reconfiguration of its security architectures, marked by the failure of militarized counter-terrorism models, the fragmentation of regional alliances, and the emergence of a governance vacuum increasingly exploited by jihadist actors. The gradual extension of JNIM's operations into western Niger and the early indicators of spillover into Benin and Togo suggest an expansion of the operational horizon aimed at stretching state response capacities rather than seeking immediate territorial conquest. This strategy of gradual expansion and consolidation, rather than peaks of volatility, requires sustained vigilance and adaptive countermeasures in the long term. The challenge for Sahelian states and their international partners now lies in recognizing that the exclusively military approach has reached its limits and that an integrated strategy, combining local governance, economic development, and security, remains the only viable path to breaking the cycle of violence engulfing the region.
