Palestinian children, wounded during fighting between Israeli forces and Hamas militants near a compound housing a U.N. school in Beit Hanoun, in the northern Gaza Strip, are treated as they lie on the floor of an emergency room at the Kamal Adwan hospital in Beit Lahiya, Thursday, July 24, 2014. Israel acknowledged that troops fired a mortar shell that hit the courtyard of a U.N. school in Gaza last week, but said aerial footage shows the yard was empty at the time and that the shell could not have killed anyone. It also stated that shell was not fired at the school intentionally.
