“So, the soldiers that sometimes capture some of the weapons will see better, but the weapons they use, the ammunition they use, sometimes they even have more ammunition than our soldiers.

Boko Haram emerged in the early 2000s in Borno State, but became a major security threat after its leader, Mohammed Yusuf, was killed in police custody in 2009.

The group escalated its violent campaign against the Nigerian state, including bombings, mass abductions and attacks on military and civilian targets.

In 2012, at the height of Boko Haram’s violence, reports surfaced that the sect named Buhari among respected northern leaders they trusted to mediate between them and the government.

Buhari, however, publicly rejected the offer at the time, accusing the Jonathan administration of trying to drag his name into the crisis for political reasons.
