Boko Haram's leader Abubakar Shekau killed himself in a fight against rival jihadist fighters from the Islamic State West Africa Province (Iswap) according to audio AFP obtained from the group Sunday, two weeks after reports emerged that he had died.
His death marks a major shift in Nigeria's 12-year-old jihadist insurgency that has killed more than 40,000 people and displaced around two million in the northeast.
