The Expansion of JNIM Beyond the Sahel: A Changing Strategic Threat to West Africa

The security configuration in West Africa is undergoing a profound transformation as Jama'at Nusrat al-Islam wal-Muslimin (JNIM), the jihadist coalition affiliated with al-Qaeda, intensifies its operational pressure beyond its traditional strongholds in the central Sahel. Operational data from January 2026 confirms that the group is not in a phase of decline or containment, but is instead pursuing a deliberate strategy of gradual expansion that places the entire coastal region on alert.

According to the strategic analysis published this week by regional security experts, JNIM demonstrates a remarkable ability to regenerate its operational tempo after short periods of relative normalization. The increase in the volume of attacks in January 2026, combined with the systematic targeting of regular armed forces, auxiliary militias, and foreign security partners, underscores the institutional resilience of the movement. This dynamic fits within a doctrine of institutional attrition rather than episodic escalation, aimed at degrading state mobility and undermining local security architectures.

The International Crisis Group, in a report published on February 21, highlights the strategic dilemma facing JNIM in its expansion into coastal countries. While the group has demonstrated its ability to project power beyond the borders of Mali, Burkina Faso, and Niger, it shows some hesitation regarding the establishment of a lasting presence in these new territories. This tactical caution reflects the logistical and political challenges of establishing a foothold in forested areas, which are very different from the Sahelian spaces where the movement has built its base.

The border regions between Benin, Niger, and Nigeria are gradually emerging as a strategic point for armed groups from the Sahel and northern Nigeria. JNIM and the Islamic State in the Greater Sahara (EIGS) are strengthening their presence in these areas, creating a territorial network that connects previously isolated spaces. The W-Arly-Pendjari complex, which spans Niger, Burkina Faso, and Benin, illustrates this dynamic of using remote protected spaces as rear bases for cross-border operations.

The extension of JNIM's operations westward into Niger, combined with ongoing incursions into Benin and Togo, suggests an expansion of the operational horizon aimed at stretching state response capabilities and exploiting cross-border depth rather than seeking immediate territorial conquest. This approach closely aligns with al-Qaeda's regional doctrine, which prioritizes longevity, local entrenchment, and political relevance over spectacular mass attacks.

Alongside these security developments, the regional political environment is experiencing significant reconfigurations. The Alliance of Sahel States, comprising Mali, Burkina Faso, and Niger under military leadership, continues its institutional solidification projects, notably with the introduction of a common visa and a Sahelian currency. These initiatives aim to strengthen the autonomy of the bloc in the face of the Economic Community of West African States (ECOWAS), from which these three countries have withdrawn.

Guinea, on the other hand, marks a return to ECOWAS following the electoral victory of General-President Mamadi Doumbouya earlier this year. The presence of Nick Checker, the highest official of the Africa Bureau of the U.S. State Department, at Doumbouya's inauguration, followed by his visit to Bamako, signals the Trump administration's intention to re-engage in this area. Washington's return to the Sahel could reshape the regional landscape by reconnecting Sahelians with the West and potentially altering the course of local counter-terrorism efforts.

The renewed attention on the Guinean president likely stems from the projection of rapid economic growth for the country in 2026, with expected growth rates exceeding 10%. Guinea possesses one of the largest bauxite reserves in the world as well as largely untapped iron reserves, making it a strategic economic partner in a context of competition for access to critical resources.

In the face of jihadist expansion, ECOWAS announced last September the planned deployment of 1,650 personnel in 2026 as part of a Rapid Deployment Force. This initiative represents an attempt to reaffirm regional capacity to manage security crises without excessive dependence on external actors. However, the effectiveness of this force will largely depend on rebuilding trust between coastal and Sahelian countries, which has been seriously eroded by the rise of military regimes in the Sahel in recent years.

The flows of displaced populations from the Sahel to Côte d'Ivoire, Guinea, Mauritania, and Senegal place border communities under increasing pressure. The heightened vulnerability to cross-border attacks from militant Islamist groups also risks destabilizing local communities and the governments of these countries. This humanitarian dimension of the crisis underscores the urgency of a coordinated regional approach that goes beyond purely military security responses.

The International Crisis Group recommends that regional authorities keep in mind that the fight against jihadist groups requires effective inter-state cooperation, possible only if coastal and Sahelian countries rebuild the trust undermined by the rise of military regimes. The report also suggests that states explore the possibilities of agreements with jihadists aimed at reducing levels of violence, a controversial approach that has shown some results in other insurgency contexts.

The threat level remains classified as high, with an upward trajectory characterized by gradual expansion and consolidation rather than spikes of volatility. The primary risk areas include Mali, Burkina Faso, and western Niger, with emerging pressure towards Benin and Togo. The time horizon of this threat extends over three to six months, with a medium to high level of confidence in these projections.

What distinguishes the current approach of JNIM from that of other jihadist groups is its ability to exploit chronic governance deficits, socio-economic vulnerability, and uneven state presence. These structural conditions, long evident in northern Mali and historically exploited by autonomist and separatist movements, continue to be the main enabling factors for armed mobilization. In this context, jihadist recruitment is less a function of massive ideological adherence than of the ability to convert local grievance systems into mechanisms of compliance, protection, and mobilization.

Where the state is absent, predatory, or inconsistent, armed actors capable of imposing order, resolving conflicts, and regulating daily life retain a decisive advantage. This dynamic, widely documented in the international analytical and academic literature on Sahelian insurgencies, remains central to understanding the sustainability and expansion of JNIM.

The African Union summit held last weekend in Addis Ababa saw leaders discussing these pressing issues despite an official theme centered on water and sanitation. Mahmoud Ali Youssouf, chairperson of the African Union Commission, issued a clear warning: "From Sudan to the Sahel, to the east of the Democratic Republic of the Congo, in Somalia and elsewhere, our peoples continue to pay the heavy price of instability."

As international actors make security commitments to countries like the DRC, it can be expected that regional African organizations will assert their determination to ensure the security of their populations, wary of foreign troops or even private militias occupying African soil. The year 2026 thus represents a historic opportunity for Africa to carve out its role in the emerging global order, including in managing geopolitical turbulence.

The persistence and scale of JNIM's activity point to a structurally embedded threat environment. The trajectory is better described as gradual expansion and consolidation, not as spikes of volatility, justifying sustained vigilance and adaptive countermeasures rather than short-term crisis responses. Regional authorities and their international partners will need to demonstrate a nuanced understanding of local dynamics and a capacity for strategic adaptation to effectively contain this evolving threat.
