The results of the army's investigation into the killing of the 7 aid workers in Gaza showed "that incident should not have happened" and is "against operational standards" "The attack - it is explained - is a serious error which derives from a serious shortcoming due to incorrect identification, errors in decisions and an attack contrary to operational standards", says the IDF. The IDF will "hold up those responsible" for the attack on the World Central Kitchen (Wck), says the Chief of Staff.
