"First came an explosion in the street outside. Then the sound of a single rifle bullet slicing through the sky in a sharp crack and into the apartment directly above the home of Raed Abu Saif, the same apartment into which his young daughter Safa had just gone. It was Saturday afternoon, about 4pm. Abu Saif hurried upstairs and found, lying on the floor of the front room, Safa, aged 12. There was a hole in her chest where the bullet had entered and a hole in her back where it had exited. It took her three hours to die."
