For more than 15 years, the extremist group Al Shabaab has been fighting a bloody insurgency in Somalia. They are one of the world’s most dangerous terrorist organisations - responsible for killing hundreds of people including innocent civilians. Our Africa correspondent, Jamal Osman, is the first journalist that has been allowed to film the group in years, speaking to one of the group’s leaders about why they continue to kill and hurt fellow Muslims in Somalia. Today, Kiran talks to Jamal about whether Al Shabaab is changing its tactics to appeal to a wider base - and whether the West is paying enough attention to these types of groups as Africa becomes the frontline of Islamic terrorism in the world.
