In this Monday, Oct. 21, 2013 photo, Jordanian youths play on a hill on the outskirts of Zarqa, Jordan’s industrial center where thousands of Syrian refugees are living, northeast of the capital Amman. More than 420,000 Syrian refugees have settled in Jordan’s cities, struggling for survival on U.N. foods stamps and straining the meager resources of a country that absorbed millions of exiles from the region’s hotspots in the past.
