The Sahel region is witnessing a dangerous escalation in conflict as jihadist militant groups broaden their reach from traditional strongholds into coastal West Africa. This expansion is not only intensifying violence but also triggering economic warfare strategies designed to cripple regional governments and disrupt daily life.
Key statistics from 2025
- Over 10,000 fatalities recorded in Burkina Faso, Mali, and Niger due to political violence between January and November 2025.
- 30 foreign nationals kidnapped in Mali (22 cases) and Niger (8 cases) by militant factions.
- Benin experienced nearly 70% more fatalities in the first 11 months of 2025 compared to the same period in 2024.
Militant groups escalate campaigns in central Sahel
In 2025, militant organizations such as Jama’at Nusrat al-Islam wal-Muslimin (JNIM) and the Islamic State Sahel Province (ISSP) have significantly expanded their operations across Mali, Burkina Faso, and Niger. Their tactics now extend into Benin, Niger, and Nigeria’s border regions, where they are establishing new conflict zones.
Economic warfare has emerged as a deliberate strategy employed by these groups to destabilize governments and undermine regional stability. In Mali, JNIM implemented a comprehensive fuel and transport blockade targeting Kayes and Nioro du Sahel, disrupting trade routes between Bamako and surrounding regions. This resulted in severe fuel shortages and dramatic price increases nationwide, directly impacting civilians and government credibility.
Burkina Faso has faced relentless JNIM offensives targeting both military forces and civilian defense groups like the Volunteers for the Defense of the Homeland (VDP). In May 2025, militants briefly seized control of Djibo and Diapaga, demonstrating unprecedented military capabilities. September brought one of the deadliest attacks on Burkinabé forces when JNIM ambushed a military convoy near Koubel-Alpha in Soum province, killing approximately 90 soldiers.
While Niger has experienced less intense violence compared to its neighbors, militant activity has spread to southern Dosso and northern Agadez regions. ISSP has intensified attacks on critical infrastructure, particularly the Benin-Niger oil pipeline in Dosso and Tahoua regions. The October kidnapping of an American citizen in Niamey highlighted the growing threat to urban centers previously considered secure.
Both JNIM and ISSP have launched coordinated kidnapping campaigns targeting foreign nationals, particularly in Mali and Niger. JNIM’s strategy focuses on industrial facilities, mining operations, and transit routes, while ISSP has broadened its targets to include high-value Western nationals, often outsourcing abductions to criminal networks.
New conflict frontline emerges in West Africa’s tri-border region
The Benin-Niger-Nigeria borderlands have become a critical flashpoint where Sahelian and Nigerian militant factions are consolidating their presence. This development is transforming the region into a unified conflict zone with implications for both Sahelian and coastal West African security.
Throughout 2025, JNIM has intensified cross-border operations from eastern Burkina Faso into northern Benin, resulting in the deadliest year on record for the country. By mid-year, the group had advanced further south into the Borgou department along the Nigerian border, marking a significant southward expansion beyond traditional northern strongholds. JNIM claimed its first attack in Nigeria in late October, signaling the group’s evolving operational reach.
Meanwhile, ISSP has strengthened its foothold in southwestern Niger, advancing toward Gaya near the Benin border while maintaining operations in Nigeria’s Sokoto and Kebbi states. The group has systematically attacked villages, security outposts, and critical infrastructure along the Niger-Nigeria border. Both Sahelian factions have now established operational zones in northwestern and western Nigeria, creating a contiguous conflict zone from Mali to western Nigeria.
This merging of previously distinct conflict theaters represents a turning point in regional security. Groups including JNIM, ISSP, Ansaru, Mahmuda, Islamic State West Africa Province factions, and bandit elements are increasingly operating in shared spaces along these borders. As their areas of operation converge, new patterns of violence and group interactions are likely to emerge in 2026.
Sahelian military regimes face mounting internal and external pressures
Military-led governments in the central Sahel are struggling to maintain control as militant groups erode state authority across vast territories. In Mali, JNIM’s fuel blockade continues to cripple the economy and daily life, while in Burkina Faso, years of military attrition have left defense forces overstretched.
JNIM’s temporary capture of major towns in Burkina Faso demonstrates the group’s strategic evolution and potential to threaten regional capitals like Fada N’Gourma. The combination of heavy military losses, territorial reductions, and economic disruption is creating fertile ground for internal dissent and potential coup attempts against incumbent military regimes.
Across the region, militant groups now contest sovereignty over rural territories where they enforce alternative governance systems, tax local populations, and control access to essential services. Their influence is expanding toward major urban centers once considered secure. ISSP’s incursions into Ayorou, Tillabéri, and even Niamey illustrate that no area remains beyond militant reach.
Local defense groups that have been central to counter-insurgency efforts are increasingly compromised. In Mali, many Dozo militias have either been disarmed or forced into alliances with JNIM, leaving communities dependent on militant-imposed security arrangements. In Burkina Faso, the VDP has suffered significant losses and remains primarily defensive, limiting the state’s territorial recovery capabilities.
Russia’s military partnership with Sahelian states has produced limited results since replacing the Wagner Group with Africa Corps. While Africa Corps has provided some support in securing fuel convoys and critical routes in southern Mali, broader security challenges persist. This partnership is expected to remain crucial in 2026 as juntas struggle to maintain control over major transit routes and urban centers amid escalating militant pressure.
The convergence of sustained militant offensives, weakened local defense forces, and declining state legitimacy creates significant risks of political destabilization in the central Sahel. If current trends continue, 2026 may witness deeper political fragmentation and territorial division across the central Sahel and its southern borders.
