A new video related to the Boko Haram shows a man claiming to be the Islamist group's leader Abubakar Shekau.
According to News 24, screen grabs of the video show a figure in boots and combat fatigues who looks similar to the man claiming to be Shekau in previous videos.
In the video, the man says in the northern Hausa language that he will only die the day Allah takes his breath.
He says that nothing will kill him until his days are over.
The Nigerian military earlier claimed they had killed a man posing as Boko Haram leader Abubakar Shekau during fighting in the town of Konduga, in Borno state.
The military announced the death of Shekau himself a year ago, saying he was killed in a battle.
