In this Friday, April 4, 2014 photo, Syrian girls play in an unofficial refugee camp on the outskirts of Amman, Jordan. The camp has fewer than 100 tents, some of them using UNHCR tents from the sprawling Zaatari refugee camp, near the Syrian border and others made of rice and flour sacks. The site has no electricity and no water. Activists come to donate water containers, and the residents feed off the electricity from the factory or the nearby wholesale vegetable market. Some of the refugees have already set up satellite dishes. (AP Photo/Khalil Hamra)

Life in this sprawling camp, Zaatari, is only getting harder for 130,000 residents, most of them fleeing fighting in south Syria. Security has become hard to control. Earlier this month, an angry mob of refugees attacked Jordanian police, throwing rocks, prompting police to fire tear gas, and there were reports of live ammunition in fighting that left one refugee dead and 28 police wounded. The angry protests were sparked after police detained a family of refugees and a driver who tried to smuggle them out of the camp.(AP Photo/Khalil Hamra)
