With Hungary's border with Croatia closed, thousands of refugees and migrants are instead making their way to Slovenia.
More than 12,000 refugees and migrants have crossed into Slovenia since Wednesday, as hundreds of thousands of people fleeing war and poverty make their way to northern Europe before winter. Freezing temperatures, wind and rain have made the journey increasingly difficult.
One photo, captured Thursday by Getty Images photographer Jeff J. Mitchell, shows a police officer escorting a group of refugees and migrants across the border from Croatia into Slovenia, holding the hand of a young girl.
The Huffington Post's Sophia Jones recently traveled with Syrian refugees for three weeks as they crossed seven countries. Read her account here.
