Tensions have been rising along the Poland-Belarus border, with thousands of migrants caught in the middle, with nowhere to go. We talk to Crystal van Leeuwen, the global co-ordinator of emergency response with Médecins Sans Frontières, about what she saw at the border recently; and discuss the politics behind the crisis with Yauheni Andreichyk, chief editor with Voices from Belarus; and Felix Krawatzek, a senior researcher at the Centre for East European and International Studies in Berlin.
