After being silent for many months, Boko Haram has rolled out a new video.
The militant group in the video released on social media deny recent successes claimed by the Nigerian military.
A masked person clad in military outfit and flanked by well-armed fighters said they are still operating in the Sambisa forest.
They also promised to counter any attack by the army.
The person who appeared in the video was not the group leader Abubakar Shekau and he did not introduce himself or make any reference to Shekau.
