For those who wonder if Hamas really does operate underneath the Al-Shifa hospital, here’s an account from Taghreed El-Khodary and Ethan Bronner of the New York Times, back in 2008:
At Shifa Hospital on Monday, armed Hamas militants in civilian clothes roved the halls. Asked their function, they said they were providing security. But there was internal bloodletting under way.
In the fourth-floor orthopedic section, a woman in her late twenties asked a militant to let her see Saleh Hajoj, her 32-year-old husband. She was turned away and left the hospital. Fifteen minutes later, Hajoj was carried out of his room by young men pretending to transfer him to another hospital section. As he lay on the stretcher, he was shot in the left side of the head. A bit of brain emerged on the other side of his skull.
