But this one comes amid reports of a split between some Boko Haram factions and the so-called Islamic State for whom the African group pledged allegiance to a year ago. Analysts say the splintering stems from disagreements over who should lead Boko Haram, which has lost most of its territory in the last year from a campaign by the Nigerian military and other African states.
