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.

Israel's military said that at least 106 packages of aid were airdropped Saturday as Italy and Greece joined the multicountry effort for the first time. Footage from Italy's defense ministry showed not only packages being parachuted over Gaza but the dry and devastated landscape below.
