In this Monday, July 14, 2014 photo, young Palestinian girl Fulla Attar, 10, rests in a classroom of the New Gaza Boys United Nations school, where dozens of families have sought refuge after fleeing their home in fear of Israeli airstrikes. 20 U.N. schools took in more than 17,000 displaced Gazans, many of them children, after Saturday's warnings by Israel that civilians must clear out of northern Gaza.
