An Israeli airstrike targeted and destroyed a high-rise building in Gaza City that housed offices of The Associated Press and other media outlets hours after another Israeli air raid on a densely populated refugee camp killed at least 10 Palestinians from an extended family, mostly children, on Saturday. The strike on the high-rise came nearly an hour after the military ordered people to evacuate the 12-story building, which also housed Al-Jazeera, other offices and residential apartments.
