Prime Minister Benjamin Netanyahu warned Palestinian civilians on Sunday to leave immediately any site where militants are operating, one day after Israel flattened a 13-story apartment block in Gaza.
Israeli aircraft fired a non-explosive rocket at the building as a signal to residents to get out before attacking it on Saturday. Seventeen people were wounded in the strike on the structure, which Israel said had housed a Hamas command center.
"I call on the inhabitants of Gaza to evacuate immediately from every site from which Hamas is carrying out terrorist activity. Every one of these places is a target for us," Netanyahu said in public remarks at a cabinet meeting.
With no end in sight to fighting in its seventh week, Netanyahu's tough talk seemed to indicate a move toward bolder strikes against Hamas targets in densely populated neighborhoods, even at the risk of raising more international alarm.
Hours after Netanyahu spoke, a cluster of 10 homes, one belonging to a Hamas member, was destroyed in an air strike in the southern Gaza town of Khan Younis, neighbors said.
