Sheikh Dr. Nizar Rayyan - one of the most prominent leaders of Hamas in Gaza - was killed in an air strike in the Gaza Strip, the first such attack in its six-day-old offensive. The air strike killed Nizar Rayyan along with nine other people, including his wife and three children, Hamas said. Another 25 people were wounded. Israeli security sources reported that the house was also used as an arms cache, a communications headquarters and concealed a tunnel opening. It was Dr. Rayyan, who cynically initiated to use the Palestinian civil population as a human shield to protect Hamas’ targets and homes against Israeli air strikes, knowing the sensitivity of the Israeli army in avoiding civilian casualties. Hamas used this fact in their terrorist build up of infrastructure during the recent temporary cease fire.
