Thank you for the Hamas talking point you regurgitated. Your number comes directly from Hamas and is a propaganda message you voluntarily spread for your ally.
~8500 of that number were active Hamas terrorist combatants, another ~1000 were other terrorist groups that operate in Gaza. But your omission is exactly what they seek with their propaganda that indoctrinates, radicalizes, and ultimately provides more terrorist recruits.
EDIT: Oh and don’t forget about the hospital that Hamas hit with a rocket as they attempted a war-crime against Israel. Those victims are in that number too. ;)
