Newsweek talked to gunmen who admitted using a hospital for firing at Israel:
One of the most notorious incidents during the war was the Jan. 15 shelling of the Palestinian Red Crescent Society buildings in the downtown Tal-al Hawa part of Gaza City, followed by a shell hitting their Al Quds Hospital next door; the subsequent fire forced all 500 patients to be evacuated . . . In the Tal-al Hawa neighborhood nearby, however, Talal Safadi, an official in the leftist Palestinian People's Party, said that resistance fighters were firing from positions all around the hospital. He shrugged that off, having a bigger beef with Hamas. "They failed to win the battle."
