Nigeria and Niger Retreat — JNIM and ISSP Exploit the Security Fracture in 2026

In Katsina and Sokoto, in northern Nigeria, the threat no longer comes solely from local armed groups. Incursions attributed to Jama’at Nusrat al-Islam wal-Muslimin (JNIM) and the Sahelian province of the Islamic State (ISSP) are now appearing in a border area where military cooperation has diminished at the very moment when jihadist groups seek to move down towards the coastal states. This shift is less spectacular than a city takeover, but it is operationally more significant: it transforms a 1,608-kilometer border into a series of exploitable corridors.
The available elements do not allow for attributing each attack to a single chain of command. Nigerian authorities must also manage banditry, kidnappings, cattle theft, and community conflicts. However, this uncertainty should not be confused with the absence of a trend. JNIM and ISSP are testing the same weaknesses as local groups: poorly monitored secondary roads, compartmentalized intelligence, and populations caught between multiple authorities.
A Border That Has Become a Political Problem
Since the coup in Niger in 2023, relations with Abuja have deteriorated. The rift deepened when Niamey, along with Burkina Faso and Mali, left the Economic Community of West African States (ECOWAS) and withdrew from the Multinational Joint Task Force (MNJTF), which combats armed organizations around Lake Chad. These decisions do not eliminate ground contacts: Nigerian Chief of Staff Olufemi Oluyede indicated in May that the two armies were still cooperating along the border. However, they make this cooperation less regular, less institutionalized, and more difficult to plan.
The Africa Defense Forum described the current paradox in September 2026: officers continue to talk, and units can still coordinate occasionally, while the regional political frameworks that facilitated this coordination have disintegrated. The crisis is therefore not a complete closure of the border. It is worse for a planner: it is a border that is open in places, but without a reliable common procedure when a column, an informant, or an armed group crosses it.
Jihadism Exploits the Spaces Between Institutions
On the ground, JNIM and ISSP do not need to officially control a Nigerian district. They simply need to use rural areas as relays, recruit from marginalized communities, and subcontract certain tasks to criminal networks. In the northwest, conflicts related to cattle and kidnapping economies already provide intermediaries, guides, and sources of funding. The group that then brings doctrine, weapons, or propaganda capability can remain invisible while increasing violence.
The northeast follows a different logic. Boko Haram and the Islamic State in West Africa (ISWAP) maintain their own structures there, particularly in the states of Borno and Yobe. Reports of personnel movement between Islamic State factions still need to be verified. However, they are consistent with the geography of the theater: the Lake Chad basin offers routes, markets, and sanctuaries different from those of the Niger–Katsina–Sokoto corridor. For the insurgents, these spaces are not separated by administrative borders. For the general staffs, they still are.
The Trap of the Abuja–AES Face-off
The rhetorical dispute exacerbates the problem. When President Bola Tinubu stated in July that insecurity in the countries of the Sahel States Alliance (AES) was also degrading Nigeria's security, AES authorities rejected this interpretation and summoned the Nigerian chargé d'affaires in Burkina Faso. Their argument is politically defensible: the juntas refuse to be portrayed as the source of all regional ills. But, on the ground, the quarrel diverts attention from the useful question: which unit can pursue a group after it crosses from one side to the other?
Sahelian governments and Abuja do not need to share a political vision to share an alert, an aerial photograph, or a list of stolen vehicles. They need simple, reversible mechanisms that are protected from political publicity. Without this, each army tends to defend its national narrative instead of closing the tactical corridor. This is precisely the environment in which jihadist organizations thrive.
What This Changes for Operations
Nigeria's priority should not be to uniformly militarize the entire border. A line of 1,608 kilometers cannot be secured with isolated posts. Resources must be concentrated on crossing routes, markets, and water points that connect banditry areas to jihadist spaces. Units must also be able to quickly transmit an alert to their Nigerian counterparts, even when the diplomatic relationship is cold. Human intelligence will be crucial: a drone can spot a column, but it will not always indicate why it is heading towards a specific community.
For Niamey, the risk is the opposite. Denouncing Nigerian interference may mobilize public opinion, but it does not replace patrols or local coordination. An attack attributed to JNIM or ISSP in northern Nigeria will not necessarily remain a Nigerian problem: its preparations, recruiters, and supplies may be located in Niger. The refusal to acknowledge this operational depth offers armed groups free maneuverability.
The next alert may not be an offensive against a capital. It could take the more mundane form of a series of kidnappings on a road, an attack on a border market, or an armed group that changes its name after crossing the border. This is how the degradation of an operational theater is measured: when political maps remain stable, but tactical routes become continuous.

JNIM and ISSP exploit security fractures along the Nigeria-Niger border in 2026, conducting incursions into Katsina and Sokoto. The border has transformed into exploitable corridors for jihadist activities, as local authorities struggle with banditry and community conflicts. Cooperation between Nigerian and Nigerien forces has decreased since the 2023 coup, complicating efforts to address the rising threat.
- JNIM and ISSP are conducting incursions into Nigeria from Niger.
- The border has become a series of exploitable corridors for jihadist groups.
- Nigeria's military cooperation with Niger has diminished since the 2023 coup.
- Local authorities are overwhelmed by banditry, kidnappings, and community conflicts.
- The jihadist groups are recruiting from marginalized communities.
