Intelligence services are checking the authenticity of a video which Islamic State said showed its leader Abu Bakr al-Baghdadi, but if real it would reinforce that fact that the group is still active, France's defense minister said on Tuesday. 'The video of al-Baghdadi - the Caliph without a caliphate - is to be considered with caution at this stage. French services are analyzing it,' Florence Parly said on Twitter. 'If this video is authentic, it confirms what we have repeated: Daesh (Islamic State) has no territory, but Daesh has not disappeared.'
