Israeli air strikes on the densely populated urban areas of the Gaza Strip had by Thursday evening killed 109 Palestinians, among them 28 children, and had wounded 621 persons. The Israeli Air Force deliberately destroyed some of Gaza’s taller buildings, alleging that the ruling Hamas party had offices in them. They gave advance warning so that families could leave their homes. But the huge bombs falling on a civilian city inevitably did damage also to nearby buildings and have left families homeless. Flying glass and debris injured noncombatants.
