NEW YORK — The UN Security Council has called for an "immediate ceasefire" in Gaza, after the US did not veto the measure in a shift from its previous position.

It also demanded the immediate and unconditional release of all hostages.

It is the first time the council has called for a ceasefire since the war began in October after several failed attempts.

The move by the US signals growing divergence between it and its ally Israel over Israel's offensive in Gaza.

In an unusually strong rebuke, a statement from Israeli Prime Minister Benjamin Netanyahu's office said the US had "abandoned" its previous position which had directly linked a ceasefire to a hostage release.

"Regrettably, the United States did not veto the new resolution," it said.

The statement said this harmed efforts to release hostages by giving Hamas hope it could use international pressure on Israel to achieve a ceasefire without freeing the captives.

It also said Netanyahu had decided to cancel meetings between an Israeli delegation and US officials in Washington that were scheduled for this week.

Israel's defense minister said Israel would not stop the war in Gaza while hostages were still being held there.

The Palestinian representative to the UN, Riyad Mansour, welcomed the resolution but said it was overdue.

"It has taken six months, over 100,000 Palestinians killed and maimed, two million displaced, and famine, for this council to finally demand an immediate ceasefire," Mansour said.

Hamas, the Palestinian Islamist group which governs Gaza and which triggered the war with an unprecedented attack on Israel on Oct. 7, also welcomed the resolution.

It said it was ready "to engage in an immediate prisoner exchange process that leads to the release of prisoners on both sides".

The group has made any hostage release conditional on the release by Israel of Palestinians held in Israeli prisons.

In the Security Council vote on Monday, the US abstained, while the remaining 14 members voted in favor.

The US had previously blocked resolutions calling for a ceasefire, saying such a move would be wrong while delicate negotiations for a truce and hostage releases were continuing between Israel and Hamas.

But on Thursday it tabled its own draft, which for the first time called for a ceasefire, marking a hardening of its stance towards Israel.

US National Security Council spokesman John Kirby said the US' decision to let the resolution pass did not mean a "shift in our policy".

He said the US backed a ceasefire but did not vote in favor of the resolution because the text did not condemn Hamas.

UN Secretary General Antonio Guterres said the resolution "must be implemented" to secure a ceasefire and the "immediate and unconditional release of all hostages".

Mark Lyall-Grant, who was the UK ambassador to the UN from 2009 to 2015, told BBC Radio 4 PM that the resolution meant Israel was now "under an obligation, essentially, to stop its military campaign for the next 15 days".

He added that the text was legally binding on Israel but not on Hamas, as the Palestinian group is not a state.

The US had previously been accused of using its power of veto to shield Israel at the UN.

However, it has become increasingly critical of Israel over the escalating death toll in Gaza, where more than 32,000 people — mainly women and children — have been killed by Israel's bombardment, according to the territory's Hamas-run Health Ministry.

The US has also pressed Israel to do more to get aid delivered to Gaza, where it says the entire population is suffering severe levels of acute food insecurity.

The UN has accused Israel of obstructing aid; Israel has blamed the UN, accusing it of failing to carry out distributions.

The war broke out after Hamas gunmen burst through the border and attacked Israeli communities, killing about 1,200 people, according to Israeli tallies, and taking 253 into Gaza as hostages.

Of those taken, 130 remain unaccounted for following a series of releases, rescues and recovery of bodies. — BBC
