In Mali, the economic siege imposed by the Jama’at Nusrat al-Islam wal-Muslimin (JNIM), an al-Qaeda-affiliated jihadist coalition, has escalated into a full-blown blockade. Over the past weekend, at least a dozen passenger buses were set ablaze along the critical Ségou-Bamako corridor, the primary supply route feeding the capital from the eastern regions. Simultaneously, key electrical infrastructure linked to the Manantali hydroelectric dam in Kayes was deliberately targeted and damaged. While Malian armed forces continue counteroffensives across multiple fronts, the economic stranglehold shows no signs of easing.

Manantali: the dam at the heart of a war of attrition

The assault on Manantali’s power transmission lines is far from a random act. Operated under a trilateral agreement between Mali, Mauritania, and Senegal within the Organisation for the Development of the Senegal River (OMVS), the dam is a cornerstone of Mali’s urban electricity grid. By striking these lifelines, JNIM is no longer merely targeting military positions—it is dismantling the backbone of the nation’s economy, where power outages instantly cripple public services, businesses, and industries.

This tactic is part of a broader, weeks-long campaign that has also seen systematic attacks on fuel convoys entering from Senegal and Côte d’Ivoire. The jihadists are weaponizing fuel shortages to destabilize the transitional government led by General Assimi Goïta, betting on public frustration to erode confidence in Bamako’s leadership. The capital, once insulated from the worst of the conflict, now stands at the center of a grinding war of exhaustion.

Army response and fragile relief in supply chains

In response, the Malian military claims to have intensified ground and aerial operations across several regions. Recent days have seen military escorts successfully escorting hundreds of fuel tankers into Bamako, temporarily easing the pressure at gas stations. Yet this respite remains fragile: each convoy demands substantial resources, and the long-term securing of national highways appears unattainable in the short term.

The Malian Armed Forces (FAMa) are also caught in a pincer movement. In central and western zones, JNIM continues to ambush civilians and destroy infrastructure. Further north, in the Kidal region, tensions remain frozen in a tense stalemate, with fresh clashes likely as rebel factions under the Permanent Strategic Framework intensify their resistance. The government in Bamako now navigates two separate fronts, with dwindling manpower and matériel.

Regional fallout from Mali’s blockade

The blockade’s ripple effects extend well beyond Mali’s borders. Neighbouring economies—particularly those of Senegal, Mauritania, and Côte d’Ivoire—are growing increasingly alarmed as West African trade corridors continue to degrade. Slowing goods flows are straining ports in Dakar and Abidjan, where a significant share of transit once served Mali and its Sahel hinterland. The Sahel States Confederation, comprising Mali, Burkina Faso, and Niger, is struggling to coordinate a unified response to the jihadists’ economic warfare campaign.

The assault on Manantali also raises urgent questions about shared regional infrastructure. Further damage could directly disrupt electricity supplies to Senegal and Mauritania, turning a Malian crisis into a continental concern. External partners—including development lenders and military suppliers—now face a delicate balancing act: supporting Bamako’s sovereignty while safeguarding critical transboundary infrastructure.

On the ground, the gap between the army’s operational claims and the harsh reality of a besieged capital underscores the unprecedented nature of this conflict phase. JNIM is no longer just contesting territory—it is attempting to suffocate an entire state.
