This week, we visit refugee camps close to Mosul to find out what life was like under "IS". We meet up with young black Germans and asked them how it was growing up in Germany. We talk to a Chilean who has spent years looking for her biological parents. And we have a look on how the German football coach Jürgen Klopp has been embraced by the English.
