[...] the residents of Shijaiyah, who've spent two weeks sleeping on floors in crowded U.N. shelters and relatives' homes, can't return home for good. [...] what was meant to be a three-day cease-fire, starting Friday, quickly unraveled over heavy clashes in southern Gaza during which an Israeli soldier was believed captured and at least 35 Palestinians were killed. Israeli troops have been combing the area for entry points to Hamas military tunnels, some with exits in Israel. Abul Qumbus blamed Hamas for his losses, saying the Islamic militants — who seized Gaza in 2007 — are sacrificing the territory's civilians for their militant ideology. Others in the neighborhood said they support the continued Hamas rocket fire on Israel and the group's stated aim to keep fighting until Israel and Egypt have lifted a seven-year-old border blockade of Gaza. "Israel is responsible" for the devastation, said Suleiman Abul Qumbus, 40, a distant relative of Bassem, sitting with other men under a tree in an open area next to his family's damaged four-story home.
