JERUSALEM (AP) – An Israeli airstrike on a house in Gaza City has killed at least seven Palestinians. The airstrike early Saturday in the western part of Gaza City recorded the highest number of fatalities in a single hit. The militant group Hamas reported the number is likely to rise as efforts to recover casualties from under the rubble of the house on the edge of Shati refugee camp are still ongoing. There is no immediate update from the Health Ministry. A resident nearby says Israeli warplanes dropped at least three bombs on the three-story house without warning its residents in advance. Shortly afterward, Hamas said it fired a salvo of rockets at southern Israel in response to the airstrike.
