An Israeli air strike on a car in the Gaza Strip killed one Palestinian on Wednesday hours after a rocket struck Israel without causing casualties, medics said. There was no immediate word on the identity of the man killed in the strike in the central Deir al-Balah district of the territory. On Tuesday evening, an Israeli air strike on Gaza killed a militant and wounded a father and his two sons, Palestinian medical sources and a militant group said. The strike, east of the central city of Khan Yunis, killed Popular Resistance Committees (PRC) member Khaled Sahmud, 24, and came after militants fired a mortar round to push back an "Israeli incursion," the group said in a statement. On Monday night, warplanes bombed a suspected weapons manufacturing site in the central Gaza Strip after a rocket was fired. The new mortar and rocket fire and retaliatory air strikes have come despite a ceasefire that came into force after a spasm of violence that followed a militant attack in Eilat on August 18, which left eight Israelis dead. Israel responded with a series of air strikes on Gaza, killing 27 Palestinians, and militant groups in the coastal enclave fired dozens of rockets into the Jewish state.
