A displaced Palestinian boy, who fled his family's house, looks up as he stays with his family at a United Nations-run school in Gaza City November 20, 2012. From the sandy expanses of the northern Gaza Strip, Palestinian families are fleeing their homes destroyed by airstrikes, but refuse to blame the Hamas rocket crews who draw Israeli fire.
