JERUSALEM — Prime Minister Benjamin Netanyahu on Tuesday vowed to press ahead with Israel’s offensive and blasted a U.N. Security Council resolution calling for a pause in the fighting, saying it had emboldened Hamas to reject a separate proposal for a cease-fire and hostage release.

As the war in Gaza grinds through a sixth month, each side has publicly insisted that its idea of victory is in reach and rejected international efforts to stem the bloodshed.

Netanyahu has said Israel can achieve its aims of dismantling Hamas and returning scores of hostages if it expands its ground offensive to the southern city of Rafah, where over half of Gaza’s population has sought refuge, many in crowded tent camps.

Hamas has said it will hold onto the hostages until Israel agrees to a more permanent cease-fire, withdraws its forces from Gaza, and releases hundreds of Palestinian prisoners, including top militants. It said late Monday that it has rejected a recent proposal that fell short of those demands — which, if fulfilled, would allow it to claim an extremely costly victory.

Israel Won’t Surrender to ‘Hamas’ Delusional Demands’: Netanyahu

Netanyahu said in a statement that the announcement “proved clearly that Hamas is not interested in continuing negotiations toward a deal and served as unfortunate testimony to the damage of the Security Council decision.”

“Israel will not surrender to Hamas’ delusional demands and will continue to act to achieve all the goals of the war: releasing all the hostages, destroying Hamas’ military and governing capabilities and ensuring that Gaza will never again be a threat to Israel.”

The war has killed over 32,000 Palestinians, according to Gaza’s Health Ministry, which does not distinguish between civilians and combatants in its tally but says women and children make up about two-thirds of those killed. The fighting has left much of the Gaza Strip in ruins, displaced most its residents and driven a third of its population of 2.3 million to the brink of famine.

An Israeli strike late Monday on a residential building in Rafah where three displaced families were sheltering killed at least 16 people, including nine children and four women, according to hospital records and relatives of the deceased. An Associated Press reporter saw the bodies arrive at a hospital.

UN Resolution Passes Cease-Fire Resolution

On Monday, the Security Council finally managed to pass a resolution calling for a cease-fire as the United States abstained instead of vetoing the measure, angering Israel in a major escalation of tensions between the two close allies. The resolution calls for the release of all hostages held in Gaza but did not condition the cease-fire on it.

Israeli Foreign Minister Israel Katz told Army Radio on Tuesday that the resolution had emboldened Hamas by signaling that international pressure would end the war without it having to make any concessions.

“The message delivered to Hamas yesterday … is that you don’t have to hurry,” Katz said.

The war began on Oct. 7, when Hamas-led militants stormed across the border and attacked communities in southern Israel, killing some 1,200 people, mostly civilians, and abducting around 250 others. It is still believed to be holding about 100 hostages and the remains of 30 others, after most of the rest were freed in November in exchange for the release of Palestinian prisoners.

The United States, Qatar, and Egypt have spent several weeks trying to negotiate another cease-fire and hostage release, but those efforts appeared to have stalled.
