Asari Dokubo, a former militant leader, has threatened to kill Nnamdi Kanu, the leader of the Indigenous People of Biafra, IPOB.
Dokubo vowed to murder Kanu with his bare hands within the courtroom.
In response to rumors that some IPOB militants had beaten him up, the former head of the disbanded Movement for the Emancipation of the Niger-Delta made the warning.
Dismissing such claims, Dokubo said the day such happens, he will practically go to court and eliminate the IPOB leader personally.
In a video shared on his Facebook page, Dokubo described such claims as falsehood.
“You can think o, You can talk, but the day you attempt all these your lies that you are lying, I will practically go and kill Nnamdi Kanu even in the court, even with Nigerian Military and all the Nigerian security agencies around.
“I will not send anybody, I will practically go there and kill him with my own hands,” he threatened.
The Niger Delta warlord and Kanu have experienced a frosty relationship over the years.
Kanu is facing charges bordering on terrorism before Justice Binta Nyako-led Federal High Court, Abuja.
