The grandfather (C) of three Palestinian children from the Al-Rifi family, who medics said were killed in an Israeli air strike, cries outside a hospital morgue in Gaza City August 21, 2014. Israel killed three senior Hamas commanders in an air strike on the Gaza Strip on Thursday, the clearest signal yet that Israel is intent on eliminating the group's military leadership after a failed attempt on the life of its top commander this week. As well as the Hamas commanders killed, Palestinian medics reported 19 other deaths on Thursday, including three children.
