Coastal West Africa — JNIM's Southern Expansion
Also known as: The Sahel spills south; Gulf of Guinea jihadist threat; coastal spillover
JNIM's expansion from its Sahelian heartland into Benin, Togo and Côte d'Ivoire is one of the most significant jihadist strategic developments of 2022–2026. The coastal states are better resourced than the AES states but share the same structural vulnerabilities.
Background
The expansion of JNIM — al-Qaeda's West African franchise — from its Sahelian heartland in Mali, Burkina Faso and Niger southward into Benin, Togo, Côte d'Ivoire and potentially Ghana, Senegal and Guinea represents one of the most significant jihadist strategic developments of 2022–2026. For more than a decade analysts warned that the Sahelian crisis would eventually reach the Gulf of Guinea; by 2024–2025 that prediction had become operational reality.
Benin and Togo have been most directly affected. In Benin, JNIM has operated in the northern Pendjari and Atakora regions since approximately 2019, attacking gendarmes and security forces, kidnapping foreign tourists in Pendjari National Park, and establishing community infiltration where state presence is thin. Benin's government has deployed forces in the north and pursued a dual military-development strategy, but the security situation has deteriorated significantly since 2022. In Togo, JNIM attacks in the northern Savanes region — bordering Burkina Faso's Sahel and Est regions — led to a state of emergency in 2022 that has been repeatedly extended; a March 2025 ambush killed 16 Togolese soldiers, the most lethal single attack in the country's modern history.
In Côte d'Ivoire, JNIM has conducted incursions into the Comoé National Park area and the Bounkani and Tchologo regions bordering Burkina Faso. The government has responded with military operations and investment in northern development programmes, but the underlying vulnerabilities — poor governance of the north, Fulani community grievances and proximity to jihadist-controlled areas of Burkina Faso — remain. JNIM's stated ambition to reach the Gulf of Guinea gives the coastal expansion a strategic rather than merely opportunistic character.
Main Actors
- JNIM (Jama'at Nasr al-Islam wal Muslimin)
- Al-Qaeda's West African franchise, expanding south from Burkina Faso through the tri-border areas into the coastal states. Combines attacks on security forces with community infiltration and the provision of alternative governance.
- Benin
- Confronting JNIM in the Pendjari and Atakora regions since 2019 with a dual military-development strategy; security has deteriorated significantly since 2022.
- Togo
- Under a state of emergency in the Savanes region since 2022. A March 2025 JNIM ambush killed 16 soldiers, the most lethal single attack in Togo's modern history.
- Côte d'Ivoire
- Facing JNIM incursions in the Comoé National Park area and the Bounkani and Tchologo regions; responding with military operations and northern development investment.
- ECOWAS and Gulf of Guinea partners
- Coordinating a coastal security framework established in 2023 covering Ghana, Togo, Benin and Côte d'Ivoire, with support from international partners.
Drivers
- JNIM's strategic ambition to reach the Gulf of Guinea, giving the expansion a deliberate rather than opportunistic character
- Marginalised northern communities and thin state presence in border districts of Benin, Togo and Côte d'Ivoire
- Fulani pastoralist grievances and friction over land, water and transhumance corridors
- Spillover pressure from jihadist-controlled territory in Burkina Faso, including refugee flows and cross-border sanctuary
- Porous protected-area borders (Pendjari, W, Comoé) that provide sanctuary and infiltration routes
Timeline
2019
JNIM kidnaps French tourists in Benin's Pendjari National Park — the first clear evidence of operational presence in the coastal states.
2020–2021
JNIM attacks on security forces in northern Benin intensify; first JNIM attacks in Togo's Savanes region.
2022
Togo declares a state of emergency in Savanes; JNIM incursions near Côte d'Ivoire's border with Burkina Faso increase.
2023
JNIM attacks in northern Benin kill security forces; a Gulf of Guinea coastal security framework covering Ghana, Togo, Benin and Côte d'Ivoire is established.
March 2025
JNIM ambush kills 16 Togolese soldiers in the Savanes region — the most lethal single attack in Togo's modern history.
2025–2026
Intelligence assessments confirm JNIM community infiltration in parts of northern Benin and Togo; Ghana and Senegal conduct preventive deployments; JNIM's April 2026 Mali offensive demonstrates growing national-level strategic capability.
Humanitarian Impact
Displacement in northern Benin, Togo's Savanes region and northern Côte d'Ivoire has grown steadily since 2022, compounded by refugee inflows from Burkina Faso. Attacks on security posts, kidnappings and JNIM pressure on rural communities have curtailed farming, transhumance and cross-border trade, while school and clinic closures in border districts replicate the early pattern seen in the Sahel.
Peace Efforts
- Gulf of Guinea coastal security framework (2023–present): ECOWAS-linked coordination between Ghana, Togo, Benin and Côte d'Ivoire on intelligence sharing and border security.
- Accra Initiative: regional cooperation mechanism for information exchange, joint operations and training among coastal and Sahelian states.
- National prevention strategies: Benin and Côte d'Ivoire combine military deployment with northern development investment aimed at pre-empting community alignment with JNIM.
Current Situation
As of mid-2026, the coastal expansion is the most analytically significant new frontier of the Sahel jihadist crisis. The coastal states are better resourced, more economically developed and institutionally stronger than the Sahelian AES states — but they face the same structural vulnerabilities: marginalised northern communities, thin state presence in border areas, Fulani pastoralist grievances and religious education networks. The window for effective prevention is narrow; once JNIM has established community governance infrastructure in northern Benin and Togo, dislodging it becomes vastly more difficult.
Outlook
High and rising. The coastal states' greater resources give them a genuine preventive opportunity the AES states did not have by the time they recognised the threat. Whether that window is used effectively — through sustained military pressure, genuine community development investment, and engagement with marginalised communities before JNIM can offer them an alternative governance structure — will determine whether the Gulf of Guinea becomes the Sahel's next crisis.
