Palestinian boy, who fled his family's house following Israeli offensive, sleeps as he takes refuge inside a classroom at a United Nations-run school in Jabaliya refugee camp in the northern Gaza Strip
A Palestinian boy, who fled his family's house following Israeli offensive, sleeps as he takes refuge inside a classroom at a United Nations-run school in Jabaliya refugee camp in the northern Gaza Strip July 31, 2014. The United Nations in Gaza is struggling to withstand a flood of almost a quarter of a million refugees into shelters that have repeatedly come under Israeli fire. Eight U.N. employees have been killed since Israel launched its offensive on July 8 after rocket fire from Gaza intensified. U.N. shelters have been bombed by Israel on six separate occasions, including in another shelling of a U.N. shelter last week that killed 15 people. Israel said its forces had come under fire from the vicinity of the school on Wednesday and responded. It denies targeting civilians and says militants use innocents as human shields and their neighbourhoods as firing positions.
