Leader of the Nigerian militant group Boko Haram, Abubakar Shekau, has committed suicide, rival Islamist militants said in an audio recording.
In an audio obtained by news agencies, the Islamic State, said Shekau died detonating explosives on himself after a battle between the two groups.
Shekau was reported dead last month and has been reported killed before.
Neither Boko Haram nor the Nigerian government has confirmed his death.
In the undated audio recording, a voice thought to be that of Iswap leader Abu Musab al-Barnawi said Shekau “killed himself instantly by detonating an explosive”.
Iswap fighters hunted down the warlord and offered him the chance to repent and join them, al-Barnawi said.
“Shekau preferred to be humiliated in the afterlife than getting humiliated on earth,” he said.
