How Gaza’s hospitals became battlegrounds
The IDF released footage on November 13 that it said showed a group of armed men at the entrance of Al-Quds Hospital, at least one of whom appeared to be carrying a rocket-propelled grenade launcher. Israel said in a statement that its forces killed “approximately 21 terrorists” when they returned fire after the militants shot at their tank from the hospital, adding that civilians were seen leaving the hospital during the exchange.
The PRCS condemned Israel’s “false claims” and said no armed individuals were operating in Al-Quds. A video shared by Aburas, the PRCS relief coordinator, showed an Israeli tank firing on Al-Quds from the same location pictured in the IDF footage. The person filming ducked away from the window and a woman could be heard crying in the background.
Hamas being irregular forces may not understand that you can't shoot at people from hospitals or have much control of subunits and the IDF doesnt need much of an excuse to go on the warpath the Red crescent and the UNRWA really have limited options if armed men decide to use their facility's or just pass through that's good enough for the IDF to attack .
