'The Islamic State group has this ability to redeploy or mutate'

Peter Harling is the founder and director of Synaps, an organisation that mentors locally hired analysts and field researchers in Syria and Lebanon. He was previously the Crisis Group's project director for Iraq, Lebanon and Syria. Harling tells us what might happen to the Islamic State (IS) group now that the terror organisation has been largely defeated in Iraq and Syria. He warns that the IS group "is something that people can turn to, based on frustrations of all kinds".
