When Nigeria's militant Islamist group Boko Haram abducted more than 200 girls from a school in Chibok in April 2014, the world woke up to the brutality and strength of its insurgency. Since it launched military operations in 2009 to create an Islamic state, the group has seized vast amounts of territory in the north-east of the country and caused a humanitarian crisis affecting some three million people, according to the country's officials. In the run-up to Nigeria's elections on 14 February, Boko Haram has stepped up its attacks. There are also added fears that those living in areas controlled by the group will be unable to vote. There are many factors that have enabled the rise of Islamic militancy in the country, but the blame for some falls on the Nigerian army. Three expert witnesses offer their insight as to whether this is correct, for the BBC World Service's The Inquiry. "These are young men whose ages range between 21 and 24. "They joined the army with little or no training. They were rerouted to the battlefront without arms and ammunition, or adequate weapons." They were also frustrated, he explains, by "lack of payment of their salary and operational allowances, lack of adequate weapons and general neglect which were not attended to". This frustration spilled over, he says, when 10 of their comrades "were killed in what the soldiers believed were avoidable circumstances". This coincided with the visit of the division's General Officer Commanding. "In revolt, [some of] the soldiers protested and shot at his car," he explained. "The authorities decided to charge them for mutiny. Of course, they were tried and convicted and sentenced to death." Just a few months later, the army had a more serious mutiny on its hands after Boko Haram killed 23 soldiers and wounded 182 by invading one of Nigeria's military camps in July 2014. As a result, some soldiers refused to fight again until they received improved weaponry, given that promises had been made to adequately supply them in future. When the improved ammunition later arrived, says Mr Falana, these same soldiers fought "gallantly" - but nevertheless found themselves "arrested and charged before a court martial for mutiny" for their earlier actions.
