Palestinians seek shelter in the garden of the Shifa hospital in Gaza City
A Palestinian girl who fled an Israeli ground offensive and air strikes, stands near makeshift tents in the garden of the Shifa hospital in Gaza City July 31, 2014. Israeli Prime Minister Benjamin Netanyahu, facing international alarm over a rising civilian death toll in Gaza, said on Thursday he would not accept any ceasefire that stopped Israel completing the destruction of militants' infiltration tunnels. Gaza officials say at least 1,394 Palestinians, most of them civilians, have been killed in the battered territory and nearly 7,000 wounded. Fifty-six Israeli soldiers have been killed in Gaza clashes and more than 400 wounded. Three civilians have been killed by Palestinian shelling in Israel. Israel launched its offensive in response to rocket salvoes fired by Gaza's dominant Hamas Islamists and their allies. REUTERS/Finbarr O'Reilly (GAZA - Tags: POLITICS MILITARY CIVIL UNREST CONFLICT)

Palestinian boys, who fled houses following Israeli offensive, play soccer as they take refuge at a United Nations-run school in Jabaliya refugee camp in the northern Gaza Strip
Palestinian boys, who fled houses following Israeli offensive, play soccer as they take refuge 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. REUTERS/Mohammed Salem (GAZA - Tags: POLITICS CIVIL UNREST SOCIETY)
