Boko Haram leader calls himself 'invincible' but also tired

MAIDUGURI, Nigeria – The leader of Boko Haram says he's still in control of an important territory that the Nigerian military says it has seized back from the extremist group.

In the 10-minute video released Wednesday, Abubakar Shekau says his militants weren't defeated in the Sambisa forest of northeastern Nigeria.

Shekau tells the camera "if you have killed us, why are we still alive?"

At one point the head of Boko Haram calls himself "invincible" and vows to continue his fight to establish an Islamic caliphate. At the very end though, he also makes clear: "I am tired of this calamity; it is better I die and go to rest in paradise."

It wasn't immediately clear when or where the video was made.
