Most of the nearly 300 girls kidnapped from a school in northern Nigeria last year are still missing. Their plight temporarily brought global focus to a hideous insurgency that seems to produce new horrors every day.

More than 17,000 people have died and a million have been displaced in the Nigerian army’s six-year fight with Boko Haram. The army has been rocked by mutinies – including in the division created to fight the militants - and soldiers in other parts of the country have been dismissed for refusing orders to fight in the north. Meanwhile, human rights groups say the army can be nearly as brutal to civilians as the militants are. And in a sign of apparent growing impatience, Nigeria's neighbours have begun sending their own armies against Boko Haram. So this week we ask, Is the Nigerian Army Failing?

The soldiers, all members of the 111th Special Forces Battalion, all pleaded not guilty in court. They are also accused of refusing to deploy in August to recapture the towns of Yelwa, Bellabulini and Dambo in Borno state from Boko Haram, according to the charge sheet. Credit: AFP/Getty Images)
