JERUSALEM—Prime Minister Benjamin Netanyahu said the new war plan approved by Israel’s security cabinet includes dismantling Hamas in Gaza’s central refugee camps in addition to Gaza City, a broadening that comes as he faces criticism internationally for expanding the war and from the far-right wing his coalition for not going far enough.

The Israeli military “will prepare for taking control of Gaza City while distributing humanitarian assistance to the civilian population outside the combat zones,” Prime Minister Benjamin Netanyahu’s office said.
