Yes, Hamas are firing rockets from the southern areas using the civilians as human shields, this report from one of the southern cities they have evacuated to:
Khan Younis: A Gaza city on its knees, now with a million mouths to feed
And it is not as if this city is safe from harm. It is regularly bombed - it is still in a warzone. Collapsed buildings and piles of rubble litter the streets.
I heard rocket launches from near the hospital, as Hamas continues to strike inside Israel. That is an open invitation for retaliation.
