The disputed leader of Boko Haram has said he is still in charge of Nigeria’s militant Islamist group despite a statement by so-called Islamic State that he had been replaced.
Abubakar Shekau denounced the IS declaration that Abu Musab al-Barnawi was now leader.
Shekau accused al-Barnawi of trying to stage a coup against him.
Boko Haram is fighting to overthrow Nigeria’s government and establish an Islamic State in the north.
In the last 18 months it has lost most of the territory it had controlled after being pushed back by an offensive by the forces of Nigeria and its neighbours.
Shekau was last heard from in an audio message last August, saying he was alive and had not been replaced – an IS video released in April said the same.
In a 10-minute audio message in both Arabic and Hausa, Shekau appeared to distance Boko Haram from IS, but still called its leader Abu Bakr al-Baghdadi “caliph”.
