Refugees wait under the rain for a bus, transferring them to a processing center, in Skala Sikaminias village, on the northeastern Greek island of Lesbos, early Thursday, October 22, 2015. Greece is the main entry point for those fleeing violence at home and seeking a better life in the European Union. More than 500,000 people have arrived so far this year on Greece's eastern islands, paying smugglers to ferry them across from nearby Turkey. (Photo by Santi Palacios/AP Photo)
