Last week there was a six-year-old boy wandering in the street, with either autism or post-traumatic stress disorder, and he was screaming. It sounds awful, but somebody had tied him to a tree. The International Committee of the Red Cross talked to the combatants, and it was arranged for an ambulance crew from the Palestinian Red Crescent Society to go to rescue him. But when they went to save the child the crew was attacked and the driver shot dead.Another time I was at a hospital dealing with 180 casualties who came in. A Palestinian doctor there was in tears, sobbing uncontrollably. He told me he had been called over from another hospital in the middle of the night because of an attack.One of the casualties was a girl, about 19 or 20, who had lost her baby and sister. This surgeon amputated her right leg, performed a vascular bypass graft, shortened her femur, and fixed up her abdomen. He was crying because she was his sister.There is terrible human suffering here. It needs to stop.
