The return of tens of thousands of Nigerians to their homes in north-east Nigeria – homes from which they escaped as a result of Boko Haram insurgency — been delayed by persistent fears that the Islamist terrorist group has not been defeated, proclamations to the contrary by the Nigerian military notwithstanding. In any event, many villages have been destroyed either by Boko Haram or by the heavy-handed Nigerian military, so many of the displaced Nigerians have no homes to which to return. Boko Haram may have been weakened by the military campaign, but it is still capable of launching deadly attacks, as was underlined on Monday when twin suicide bombings killed two people at a university in Maiduguri. The city is the provincial capital of Nigeria’s north-east Borno state, the epicenter of Boko Harams seven-year campaign to create a regional Islamic caliphate.
