Syrian refugees sleep on railway lines near the train station of Idomeni, northern Greece, on Wednesday, August 12, 2015. Greece is Europe's main entry point for people arriving by sea, as the alternative route from north Africa to Italy has become increasingly dangerous due to fighting in Libya. From Greece, the migrants move north through the Balkans, hoping to gain asylum, preferably in Germany, the Netherlands or Scandinavia. (Photo by Giannis Papanikos/AP Photo)
