Palestinians inspect the rubble of a mosque, which witnesses said was hit by an Israeli air strike, in Beit Hanoun in the northern Gaza Strip August 25, 2014. Israel's Prime Minister Benjamin Netanyahu warned Palestinian civilians on Sunday to leave immediately any site where militants are operating, one day after Israel flattened a 13-storey apartment block in Gaza. Palestinian health officials say 2,115 people, most of them civilians and more than 400 of them children, have been killed in the Gaza Strip since July 8, when Israel launched an offensive with the declared aim of ending Palestinian rocket fire into its territory. Sixty-four Israeli soldiers and four civilians in Israel have been killed. Photo by Ashraf Amra
