The Sahel region is witnessing a dangerous escalation in economic warfare as militant groups extend their reach beyond traditional strongholds, reshaping conflict dynamics across West Africa. Once confined to the arid expanses of the central Sahel, violent extremist organizations are now penetrating coastal nations, creating a volatile corridor from Mali to Nigeria. This strategic shift threatens regional stability and demands urgent international attention.
Militant groups intensify campaigns in central Sahel
In 2025, Jama’at Nusrat al-Islam wal-Muslimin (JNIM) and the Islamic State Sahel Province (ISSP) significantly expanded operations across Mali, Burkina Faso, and Niger. These groups have adopted economic warfare tactics to undermine state authority and disrupt civilian life. In Mali, JNIM implemented a fuel and transport embargo targeting key cities like Kayes and Nioro du Sahel, cutting off critical trade routes from Bamako. The blockade triggered severe fuel shortages and price surges nationwide, crippling the economy and eroding public trust in the military regime. Violence in Kayes, Sikasso, and Segou reached unprecedented levels, with monthly fatalities hitting record highs since data collection began in 1997.
Burkina Faso faced similar challenges as JNIM launched sustained offensives against government forces and civilian defense groups. In May, militants briefly seized control of Djibo and Diapaga, demonstrating alarming tactical advancements. September saw one of the deadliest attacks on the country’s military in Soum province, where 90 soldiers were killed in a devastating ambush. These operations highlight JNIM’s growing military capabilities and its intent to destabilize regional governments by targeting economic lifelines and territorial control.
Niger’s vulnerability grows as militancy spreads
While Niger has avoided the scale of violence seen in neighboring countries, it remains increasingly exposed to militant activities. Conflict zones now extend into southern Dosso and northern Agadez, while ISSP has intensified attacks on critical infrastructure, particularly the Benin-Niger oil pipeline in the Dosso and Tahoua regions. The October abduction of an American citizen in Niamey underscored the militants’ ability to penetrate urban centers previously considered secure, signaling a dangerous expansion of their operational reach.
Both JNIM and ISSP have escalated kidnapping campaigns targeting foreigners, particularly in Mali and Niger. ACLED data reveals a 70% surge in fatalities in Benin compared to 2024, with militants focusing on industrial sites, mining operations, and transit corridors. ISSP has adopted a broader strategy, targeting Western nationals and outsourcing abductions to criminal networks, further complicating counter-terrorism efforts.
Coastal West Africa emerges as new conflict frontier
The consolidation of militant activity in the Benin, Niger, and Nigeria borderlands represents a critical turning point. JNIM and ISSP have transformed this tri-border region into a major conflict zone with implications for both the Sahel and coastal West Africa. Northern Benin experienced its deadliest year on record as JNIM launched cross-border operations from eastern Burkina Faso, culminating in the killing of over 50 soldiers in Park W. By mid-2025, the group had advanced further south into the Borgou department, marking a significant southward expansion beyond traditional northern strongholds.
ISSP has reinforced its presence in southwestern Niger, moving closer to the Benin border city of Gaya while continuing operations in Nigeria’s Sokoto and Kebbi states. The group’s activities now extend into northwestern and western Nigeria, where it has attacked villages, security posts, and critical infrastructure. This convergence of Sahelian and Nigerian militant factions signals the merging of previously distinct conflict theaters into a single, interconnected battleground stretching from Mali to western Nigeria.
The increasing overlap among groups like JNIM, ISSP, Ansaru, and local bandit factions creates a complex web of violence. As these organizations expand into shared territories, their interactions are likely to generate new patterns of conflict and collaboration, further destabilizing the region.
Regional instability threatens military regimes
The military-led governments of the central Sahel face mounting internal and external pressures. In Mali, the fuel embargo continues to devastate the economy, while JNIM’s sieges and blockades expose deep structural weaknesses in state control. Burkina Faso’s army and civilian defense forces are overstretched, with JNIM’s temporary capture of major towns demonstrating both the group’s strategic evolution and the state’s inability to protect key population centers. Continued military losses and territorial erosion risk triggering internal dissent and political instability, potentially setting off a domino effect across the region.
State authority is steadily eroding as militant groups contest sovereignty over vast rural territories. They impose their own social order, tax local populations, and control access to livelihoods. Even major population centers once considered safe are now within militant reach, as evidenced by ISSP’s incursions into Ayorou, Tillaberi, and Niamey. The weakening of local self-defense groups, including Dozo militias in Mali and the Volunteers for the Defense of the Homeland (VDP) in Burkina Faso, further exacerbates the crisis. Many Dozo groups have been disarmed or forced into agreements with JNIM, leaving communities dependent on militant-enforced security arrangements.
International partnerships have provided limited support. The transition from Wagner Group to Africa Corps has left large areas vulnerable, though recent deployments have focused on securing fuel convoys and supply routes in southern Mali. While this assistance may help maintain control over major transit corridors, broader security challenges persist. The combination of sustained militant pressure, weakened local forces, and declining state legitimacy creates a high-risk environment for political destabilization in 2026.
Key statistics: conflict escalation in 2025
- Over 10,000 deaths recorded in Burkina Faso, Mali, and Niger from January to November 2025 due to political violence
- 30 foreign nationals kidnapped in Mali (22) and Niger (8) during the same period
- Nearly 70% increase in fatalities in Benin compared to the first 11 months of 2024
The evolving conflict landscape demands a coordinated regional response. As militant groups expand their operations and economic warfare tactics intensify, the risk of deeper political instability and territorial fragmentation grows. The coming year will be critical in determining whether West Africa’s coastal nations can resist the spread of Sahelian militancy or succumb to its expanding influence.
