Who is a refugee?

In the aftermath of World War One, as Turkey filled with refugees fleeing a brutal civil war, the first refugee camps appeared and the international community stepped in to appoint the first High Commissioner for Refugees. In this first episode Katy Long hears stories from refugees and those who work to support them from Rwanda, Germany and Russia, as she examines how refugee crises begin, and who is considered a refugee.
