From the ISW report today: Israeli forces fought Palestinian militia fighters near the Square of the Unknown Soldier less than half a kilometer from the al Shifa Hospital complex.[1] A Palestinian journalist reported that the al Qassem Brigades—the military wing of Hamas—ambushed Israeli forces south of the Square of the Unknown Soldier on Shuhada Street.[2] Other Palestinian militia fighters fought Israeli forces on Omar Mukhtar Street, which bounds the square.[3]

If you build your defense in urban environment you are supposed to evacuate the civilians. This is standard for any half competent army.
