Boko Haram Expands the Front in Nigeria — 170 Dead Announce the Borgu-Kainji Corridor in 2026

Kaiama, Kwara State. In February, around 170 people were killed in the villages of Woro and Nuku, following an attack attributed to the Sadiku branch of Jama’atu Ahlis-Sunna Lidda’Awati Wal-Jihad, better known as Boko Haram. A few days later, the localities of Konkoso, Tunga-Makeri, and Pissa, in Niger State, were also struck. The distance between these incidents is not just geographical. It outlines a violence axis through the forests of Borgu and the Kainji Lake National Park, extending to the borders of Benin and Niger.

This is not a new battle around Lake Chad. It is more dangerous for another reason. A jihadist network that learns to operate in terrain where the state is almost absent can open a route to southwestern Nigeria, far from the traditional maps of the insurgency.

A Front That Moves Faster Than the Army

The Institute for Security Studies describes a series of massacres, kidnappings, and improvised explosive devices along the Borgu-Kainji axis. The area includes the territories of Borgu and Agwara in Niger State, Kaiama and Baruten in Kwara, as well as Bagudo, Yauri, Zuru, and Ngaski in Kebbi. These are names of districts, not front lines. For the fighters, these are forest corridors, secondary tracks, rivers, and markets where they can resupply without being seen.

Violence involving jihadist groups is reported to have increased by 86% between 2024 and 2025, while the death toll rose by 262%. These figures must be handled with caution: data collection is uneven, and authorities do not always publish a verifiable toll. But on the ground, the trend is consistent. Mass kidnappings in Kebbi and Niger, followed by attacks on villages in Kwara, show a tactical continuity that cannot be explained by mere banditry.

The government of Bola Tinubu launched Operation Savannah Shield and deployed a battalion to Kaiama. This is an understandable reaction, but it remains tied to a fixed point. However, a mobile group does not need to hold Kaiama to control the route connecting Kaiama to Kainji Park. It only needs to blow up a vehicle on Luma Road, tax loggers and miners, and then disappear into an area where the police, army, and administration do not communicate.

The Lake Chad Model Without the Lake

The danger is the reproduction of a known model. In the Lake Chad basin, factions of Boko Haram have survived by combining sanctuaries, extortion, kidnappings, and control of waterways. Borgu-Kainji offers a land version of the same equation: poorly governed forests, porous borders, and rural communities far from public services.

Kainji Lake National Park is particularly useful to a group that wants to hide, stockpile weapons, and recruit. The forest tracks allow them to bypass major routes. Niger and Benin offer cross-border passages. Revenues from timber, artisanal gold mining, ransoms, and taxes imposed on villages can finance a campaign without a commander needing a permanent base.

The ISS also reports the presence or influence of several actors: JAS-Sadiku, Lakurawa, Ansaru-Mahmuda, and a branch linked to Al-Qaeda, sometimes referred to as JNIM or JNIN when operating towards northern Benin. Not every attack should be turned into evidence of a coalition. Local alliances can be temporary, opportunistic, and motivated by access to weapons or routes. But this plurality complicates intelligence work tremendously. An army can defeat a camp and leave intact the network that supplies it with fuel, guides, and recruits.

Jihadist Competition Gains the Western Front

This expansion fits into a regional dynamic. The Africa Defense Forum reports that JNIM and the Islamic State's Sahel Province, or ISSP, have clashed multiple times in the tripartite area of Burkina Faso-Mali-Niger. According to ACLED, the two organizations have engaged in about 320 battles since 2019, causing over 2,200 deaths among their fighters. Since April 2026, this competition has extended towards Tillabéri, Dosso, and the Nigerian state of Kebbi.

The operational consequence is simple: groups are no longer just seeking to survive against government forces. They are competing for the same populations, the same traffics, and the same routes. JNIM may want to gain access to communities and trade corridors. ISSP may prioritize coercion and massacres to quickly impose its authority. Boko Haram factions, on the other hand, retain an ancient knowledge of the networks in the northeast. In western Nigeria, these skills may intersect with already established criminal groups.

The ACLED analysis estimates that the use of drones by JNIM has increased from a single reported attack in 2023 to over 80 in 2025. This figure does not mean that armed drones will dominate Borgu tomorrow. It rather indicates a technological threshold crossed: reconnaissance, propaganda, and convoy observation are becoming accessible to groups that have neither aviation nor military satellite networks. In a region where the army already lacks human intelligence, a few commercial devices may suffice to make an ambush more profitable.

The Test of Savannah Shield

The effective response will not be a punitive operation limited to Kaiama. It must cover the entire axis, with units capable of staying long enough to protect communities and rebuild local intelligence. Nigerian forces will also need to track the flows of timber, gold, and ransoms, as a jihadist column does not move without money.

Cooperation with Benin and Niger will be essential, even if political relations with Niamey remain poor. A closed border on paper does not block a forest track. Coordinated patrols, data sharing, and teams capable of verifying village alerts will have more effect than an announcement of additional deployment.

On the ground, the decisive indicator will not be the number of raids announced by Abuja, but the ability of residents to return to the road, the market, and the fields without paying twice for their security.

Nigeria still has a narrow window. If Savannah Shield remains a response to each attack, Sadiku-JAS and its rivals will have time to turn Kainji into a sanctuary. The next alert may not come from a major assault, but from a series of mines on a secondary road, a kidnapping of schoolchildren, or the disappearance of a police station. This is how a theater of operations establishes itself: through small cuts, until the day the map stops showing what the state actually controls.
