In this edition we head to Iraq, where the operation to retake Mosul from the Islamic State group is well under way. Those fighting to liberate the country's second city include the regular army, the Kurdish peshmerga, and a broader US-led coalition providing air support. However our colleagues at France 2 met with another group taking part in the operation: civilian medics from the US who have travelled to Iraq at their own expense to help with the war effort. A programme prepared by Patrick Lovett and Elom Marcel Toble.
