Boko Haram terrorists have announced a new leader. The new leader Abu Musab al-Barnawi replaces the eccentric Abubakar Shekau.


In a video clip released in January 2015, Mr al-Barnawi described himself as the spokesman for Boko Haram. This was before the Nigeria-based jihadist group pledged allegiance to IS. 

Now IS says he has replaced Mr Shekau, who has not made a verified appearance in propaganda production since August 2015.
