Rajan Datar talks to Mansur Liman, editor of the BBC's Hausa service and Behrouz Afagh, Head of BBC Asia Pacific region, about the language being used in the media to describe Boko Haram. They discuss whether words like 'Islamist' is an appropriate term to describe a group that are engaging in criminal activities outside of Islamic teaching.
