Defense Minister Ehud Barak is personally responsible for the deaths of a Palestinian mother and her four children in an IAF strike in Gaza on Monday, said MK Ahmed Tibi (UAL). "What happened in Gaza is a war crime," Tibi told Israel Radio on Tuesday morning. "[Palestinian Authority President Mahmoud] Abbas isn't responsible, the Palestinians are not responsible for these deaths." "Whoever fires a shell from an aircraft into a civilian area of Gaza is responsible for these terrible deaths and Ehud Barak is personally responsible for this terrible killing," he exclaimed. "It seems that recently Barak's hands are contaminated with blood more than any other person in our region," Tibi continued.
