Yesterday's attacks by the Israeli Air Force in Gaza City—the most densely populated piece of land on the face of the earth—indiscriminately destroyed medical and governmental buildings, homes, and other civilian infrastructure. By this morning, about 300 Palestinians, many of whom were women, children, and civil police and traffic officers (so-called Hamas “security forces”) were killed and at least 900 injured. We and many others around the world are concerned about reports from Israel that these attacks may be only the opening fanfare of a sustained military campaign that will, inevitably, create even more casualties for an already besieged people.
