Displaced Palestinians sleep on the ground on July 23, 2014 at a UN school in the refugee camp of Jabalia where families fleeing heavy fighting in the besieged Palestinian territory have taken refuge.  A United Nations school sheltering displaced Palestinians in central Gaza came under Israeli fire on July 22 as a team was inspecting damage from a day earlier, a UN official said. UNRWA is sheltering more than 100,000 people at more than 60 of its schools throughout the Gaza Strip.  AFP PHOTO / MOHAMMED ABED        (Photo credit should read MOHAMMED ABED/AFP/Getty Images)
