They are obscene. I have an officer in the camp counting the bodies. You ought to be ashamed. This situation is rotten and terrible. They are killing children. You are in absolute control of the area and therefore responsible for that area," that Draper's second call was first information about massacre and that he passed information on to Sharon's office, that the IDF claimed Phalange entered camps from north and not through IDF lines, that he passed his and Draper's reports to Ariel Kenet and David Kimche; Lt. Col.
