Family and friends of Maj. Tzafrir Bar-Or, 32, one of 13 solider's who were killed in several separate incidents in Shijaiya on Sunday, mourn during his funeral at the military cemetery in Holon, Monday, July 21, 2014. On Sunday, the first major ground battle in two weeks of Israel-Hamas fighting exacted a steep price, killing scores of Palestinians and more than a dozen Israeli soldiers and forcing thousands of terrified Palestinian civilians to flee their devastated Shijaiyah neighborhood, which Israel says is a major source for rocket fire against its civilians. The 13 Israeli soldiers were killed in Shijaiya, in gun battles and rocket attacks. In the deadliest, Gaza fighters detonated a bomb near an armored personnel carrier, killing seven soldiers inside, the army said. In another incident, three soldiers were killed when they became trapped in a burning building, it said.
