The UN says there is a major humanitarian crisis in northern Iraq: it is more than a week since Iraqis, especially minorities like the Yazidis, fled their homes after jihadists stormed their towns and villages, reportedly killing hundreds. Now thousands are stranded in barren, hot and dry mountainous regions, many have died from dehydration and lack of food. HARDtalk speaks to Masrour Barzani, head of intelligence and security in Iraq's autonomous Kurdish region. Is it the Kurds who can rescue the state of Iraq and how much outside help do they need to defeat the jihadists of the so called Islamic State?
