The MAG Corps informed B'Tselem today that it has closed the Military Police investigation file in the complaint into the killing of 21 members of the a-Samuni family in the Gaza Strip. The file was closed without taking any measures against those responsible. In response, Adv. Yael Stein, B'Tselem's head of research, said: it is unacceptable that no one is found responsible for an action of the army that led to the killing of 21 uninvolved civilians, inside the building they entered under soldiers' orders, even if this was not done deliberately. The way the army has exempted itself of responsibility for this event, even if only to acknowledge its severity and clarify its circumstances, is intolerable.
