GAZA — Israeli air strikes launched before dawn on Tuesday killed two Palestinians and destroyed much of one of Gaza's tallest apartment and office buildings, setting off huge explosions and wounding 20 people, Palestinian health officials said. Israel had no immediate comment on the attacks that took place as Egyptian mediators stepped up efforts to achieve an elusive cease-fire to end seven weeks of fighting.
Palestinian officials said 70 families lived in the 13-story building, which was listing to one side after the blasts. The structure also housed offices and a shopping complex. Hundreds of neighbors in surrounding homes were also evacuating to avoid being hurt if the structure collapses, witnesses said. Fatalities were averted by warnings issued to residents to vacate the premises and two non-explosive warning missiles fired by drones.
