Comrades of slain 20-year-old Israeli Staff Sergeant Moshe Melako of the Golani Brigade, who was killed the previous day during fighting with of Palestinian militants in the Gaza Strip, on July 21, 2014 mourn during his funeral at the Mt. Herzel military cemetery in Jerusalem. With 18 soldiers killed in Gaza, the highest military casualty toll in eight years, Israel is in mourning, but has vowed to pursue its mission against Hamas militants. The toll has been far higher on the Palestinian side, where more than 500 have been killed since Operation Protective Edge began on July 8, most of them civilians, a spokesman for Gaza's emergency services said.
