Nigeria's northwest and central border regions have transformed into a convergence zone for Sahelian and local jihadist groups, raising alarms about a widening insurgency corridor that threatens to destabilize West Africa. The area, known as the Kebbi-Kainji-Borgu triangle, spans the Nigerian states of Kebbi, Sokoto, Niger, and parts of Kwara, extending into Niger's Dosso region and Benin's Alibori department. This vast, poorly governed territory hosts a mix of homegrown jihadist factions—such as the Sadiku-led faction of Boko Haram, Ansaru, and the Mahmudawa group—alongside criminal gangs referred to locally as bandits, collectively numbering in the hundreds of thousands and responsible for raids, killings, and mass displacement.
