Displaced Palestinian children rest at the Abu Hussien UN school in the Jabalia refugee camp in the northern Gaza Strip after the area was hit earlier in the morning by Israeli shelling on July 30, 2014. Israeli bombardments early on July 30 killed "dozens" of Palestinians in Gaza, including at least 16 at a UN school, medics said, on day 23 of the Israel-Hamas conflict. Photo by Ashraf Amra
