Syrian children try to stay warm near an open fire in front of their unheated tents in a refugee camp in the town of Harmanli, Bulgaria, Thursday, Nov. 21, 2013. Thousands of Syrian and other refugees from the Middle East, Asia and Africa, who find enough courage to make a dangerous journey from their war-ravaged states, often end up in the crammed settlements in the Balkans, including Bulgaria, Greece or Serbia, after being caught on the borders of wealthy Western European nations for attempting to cross illegally.
