The new year began in Europe with predictions of a long, harsh winter and a number of countries tightening their border to control the influx of refugees. This has left many in a state of limbo, braving the elements. But it hasn't stopped the thousands fleeing violence, persecution and the search for a better life from reaching Europe's doorstep. Refugees continue to arrive by foot, over land and by sea. And for Syrian refugees and internally displaced, this begins a fifth winter, facing extreme hardship as the conflict rages on.
