The Jihadist Expansion towards the Gulf of Guinea: JNIM's Offensive Marks a Strategic Turning Point

On March 7, 2026, a coordinated attack carried out by Jama'at Nusrat al-Islam wal-Muslimin (JNIM) against two military posts in northern Benin resulted in 15 deaths among Beninese security forces and five injuries. This offensive, which struck the locality of Kofono near the Nigerien border, represents much more than a mere isolated incident: it embodies a major geostrategic transformation in the Sahel, that of the gradual migration of jihadist groups from the Sahelian areas to the coastal states of West Africa.

The Kofono attack illustrates the methodical strategy deployed by JNIM for several months. The al-Qaeda-affiliated group, which traditionally operates in the Sahelo-Saharan band covering Mali, Burkina Faso, and Niger, has gradually expanded its operational range southward. This expansion is not coincidental but responds to a well-established operational logic: faced with the increasing pressure from government forces in central Sahel and the intensification of military operations conducted by the Malian and Burkinabe armies – which eliminated more than 100 jihadist fighters between February 21 and March 6, 2026 – JNIM is seeking new sanctuaries and new areas of influence.

Benin now finds itself on the front line of this expansion. Between February 21 and March 7, 2026, JNIM conducted at least three significant attacks against Beninese military installations along the border with Burkina Faso. This intensification of operations reveals a capacity for planning and coordination that worries regional security analysts. The group demonstrates a deep knowledge of the terrain, mastery of cross-border movement routes, and the ability to strike protected military targets, indicating a level of sophisticated intelligence.

JNIM's offensive is part of a broader regional context marked by the reconfiguration of military and political alliances in the Sahel. The formation of the Sahel States Alliance (AES) in September 2023, grouping Mali, Burkina Faso, and Niger after their withdrawal from the Economic Community of West African States (ECOWAS), has created a security vacuum in border areas. Regional military cooperation mechanisms, notably the G5 Sahel and the Multinational Joint Task Force, have lost effectiveness, compromising the right to cross-border pursuit, joint military operations, and intelligence sharing between states.

This regional fragmentation directly benefits jihadist groups. JNIM methodically exploits the gaps created by the weakening of security cooperation. The group no longer hesitates to cross national borders, organizing rapid raids before retreating to sanctuary areas located in neighboring countries. This cross-border "hit-and-run" tactic significantly complicates the response of security forces, who can no longer rely on effective regional coordination.

Alongside JNIM's expansion, the Islamic State in the Greater Sahara (EIGS) also maintains an active presence in the region. On March 6, 2026, EIGS militants attacked JNIM positions in the Sebba region of Burkina Faso, causing several deaths among al-Qaeda-affiliated fighters. This inter-jihadist rivalry adds an additional layer of complexity to the regional security landscape, with both groups vying for territorial control and the allegiance of local populations.

In Nigeria, the situation is experiencing a dramatic escalation. Between March 8 and 10, 2026, the Islamic State in West Africa (ISWAP) and factions affiliated with Boko Haram conducted at least six simultaneous attacks across the states of Borno and Yobe, as well as in the Lake Chad basin. On February 3, 2026, the Lakurawa group, affiliated with the Islamic State, attacked the villages of Nuku and Woro in Kwara State after residents refused to accept the imposition of Sharia law, killing at least 162 people. These massacres illustrate the growing brutality of jihadist groups and their determination to impose their ideology through terror.

The most concerning aspect of this evolution lies in the emergence of what analysts now refer to as an "insurgency corridor" extending from the Sahel to the coastal states of the Gulf of Guinea. Ghana, Côte d'Ivoire, and Benin are now directly threatened by this jihadist wave. JNIM even conducted its first known attack on Nigerian territory in October 2025, killing a soldier and seizing ammunition and cash in Kwara State, thus demonstrating its ability to project its firepower well beyond its traditional operational zone.

In the face of this growing threat, international responses are multiplying but remain fragmented. The United States, which had significantly reduced its military presence in the Sahel after successive coups in Mali, Burkina Faso, and Niger, is now attempting a diplomatic and security return to the region. An American delegation visited Bamako in early February 2026, and negotiations are underway to allow the resumption of American surveillance drone flights over Malian territory. Washington has also lifted sanctions against several Malian officials, signaling a willingness for pragmatic re-engagement despite political tensions.

France, for its part, maintains a military presence in Benin, fueling a regional debate on the relevance of security partnerships with former colonial powers. At a consultative conference on regional cooperation and security held in Ghana on January 29 and 30, 2026, policymakers and security officials emphasized the need for enhanced coordination to counter the jihadist threat, but political divisions between AES and ECOWAS states complicate any joint initiative.

The European Union recently signed a security partnership pact with Ghana on March 11, 2026, as part of a strategy to strengthen the capacities of coastal states in the face of the migration of the jihadist threat southward. Ghanaian President John Mahama has been praised for his efforts to bring the three secessionist countries back into ECOWAS to strengthen regional integration, but the prospects for reconciliation remain uncertain.

China is also taking advantage of this geopolitical upheaval to expand its military footprint in Africa. Beijing is now providing defense systems to several countries in the region, including Senegal, Ghana, Mali, and Burkina Faso, filling the void left by the partial withdrawal of traditional Western partners. This growing Chinese presence is altering regional power balances and introducing new actors into the Sahelian security equation.

The March 7, 2026 attack on Beninese military positions is therefore not an isolated event but a symptom of a profound strategic reconfiguration in the Sahel and West Africa. JNIM and other jihadist groups active in the region demonstrate remarkable adaptability, exploiting political divisions, institutional weaknesses, and social fractures to extend their territorial grip. Without a coordinated regional response and a genuine political will for reconciliation between AES and ECOWAS states, the "insurgency corridor" risks extending even further south, directly threatening the stability of the entire West Africa region.
