Boko Haram insurgency

The Boko Haram insurgency began in 2009, when the jihadist rebel group Boko Haram started an armed rebellion against the government of Nigeria. In 2012, tensions within Boko Haram resulted in gradual split of the group between Salafist conservative faction led by Abu Usmatul al-Ansari, and the more dominant, violent faction led by Abubakar Shekau. By 2015, part of the group split into al-Qaeda affiliated Ansaru, and Shekau's faction became ISIL's West Africa branch.
