In this file video grab made on January 15, 2018 from a video released the same day by Islamist militants group Boko Haram shows Boko Haram factional leader Abubakar Shekau holding a heavy machine gun. 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 on June 6, 2021, 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.
Boko Haram has not yet officially commented on the death of their leader while the Nigerian army said it was investigating the claim.
