Boko Haram say they are responsible for the deadly attack on Maiduguri on Wednesday, which left many people dead.

A video was released by the group on Sunday and the supposedly dead Abubakar Shekau featured in it.

As usual, the voice in the video spoke in Arabic:

“We have killed those we can and have left with the bounties of war we are displaying now,” said a voice on a video released by Boko Haram on Saturday, showing the group’s fighters among piles of ammunition and other supplies.

“We are hale and hearty, contrary to claims that we have been killed.”

The raid came six months after President Muhammadu Buhari said Boko Haram had "technically" been defeated by a military campaign that had pushed many of the jihadists deep into the remote Sambisa forest, near the border with Cameroon.

But the militants further said: “God has enriched us with the arms and ammunition on display, and we shall deploy such weapons we seized against you… the war is still ongoing.

“As you look for us in the bush, we shall hunt you in the cities… There is no dialogue between us, only fire for fire.”
