The resolution, on which Algeria also voted no and Guyana abstained, called for an immediate and sustained ceasefire lasting roughly six weeks that would protect civilians and allow for the delivery of humanitarian assistance.

Eleven members of the 15-member council voted for the resolution.

The resolution reflected a toughening of Washington's stance toward Israel. Earlier in the five-month-old war, the U.S. was averse to the word ceasefire and vetoed measures that included calls for an immediate ceasefire.

"The vast majority of this council voted in favor of this resolution, but unfortunately Russia and China decided to exercise its veto," U.S. Ambassador to the United Nations Linda Thomas-Greenfield told the Security Council.

'CYNICAL' AND 'PETTY,' U.S. SAYS

She accused Russia and China of vetoing the resolution for "cynical" and "petty" reasons. She said they opposed it simply because it was penned by the U.S. and criticized both countries for not condemning Hamas's Oct. 7 attack on Israel.

"For all the fiery rhetoric, we all know that Russia and China are not doing anything diplomatically to advance a lasting peace or to meaningfully contribute to the humanitarian response effort," she told the council after the vote.

The U.S. has wanted any Security Council support for a ceasefire to be linked to the release of hostages held by Hamas in Gaza. Palestinian Hamas fighters killed 1,200 people and took 253 captive in their Oct. 7 attack, according to Israeli tallies.

Nearly 32,000 Palestinians have been killed in Israel's subsequent offensive in the Gaza Strip, according to health authorities in the Hamas-ruled enclave.

Russia's ambassador to the U.N., Vassily Nebenzia, said the resolution was "exceedingly politicized" and contained an effective green light for Israel to mount a military operation in Rafah, a city on the southern tip of the Gaza Strip where more than half of its 2.3 million residents have been sheltering in makeshift tents.

"This would free the hands of Israel and it would result in all of Gaza and its entire population having to face destruction, devastation, or expulsion," Nebenzia told the meeting.

He said a number of non-permanent members of the Security Council had drafted an alternative resolution and said there was no reason for members not to support it.

China's U.N. ambassador Zhang Jun said the text proposed by the U.S. was unbalanced and criticized it for not clearly stating its opposition to a planned military operation by Israel in Rafah in southern Gaza which he said could lead to severe consequences. He said Beijing also supported the alternative.

But Thomas-Greenfield said that measure fell short.

"In its current form, that text fails to support sensitive diplomacy in the region. Worse ... it could actually give Hamas an excuse to walk away from the deal on the table," she said.

The U.S. resolution had backed talks under way being brokered by the U.S., Egypt and Qatar over a ceasefire.

CEASEFIRE FOR MONTH OF RAMADAN

A diplomat said the alternative resolution drafted by the 10 elected members of the Security Council under Mozambique's coordination could be brought forward for a vote as soon as Friday.

That resolution, a copy of which was seen by Reuters, demands an immediate ceasefire for the Muslim holy month of Ramadan now under way, the release of all hostages and an expanded flow of humanitarian assistance to Gaza.

French President Emmanuel Macron said on Friday that his country would work with Jordan and the United Arab Emirates to persuade Russia and China to back yet another alternative resolution at the United Nations for a ceasefire in Gaza.

Washington previously vetoed three draft resolutions, two of which would have demanded an immediate ceasefire.
