Refugees walk past others resting on the ground at the border station between Serbia and Hungary near Horgos, Serbia, Wednesday, Sept. 16, 2015. Small groups of migrants continued to sneak into Hungary on Wednesday, a day after the country sealed its border with Serbia and began arresting people trying to breach the razor-wire barrier, while a first group arrived in Croatia seeking another way into the European Union.
