UNITED NATIONS (AP) — Russia and China on Friday vetoed a U.S.-sponsored United Nations resolution supporting “an immediate and sustained cease-fire” in the Israel-Hamas war in Gaza, calling the measure ambiguous and saying it was not the direct demand to end the fighting that much of the world seeks.

The vote in the Security Council became another showdown involving world powers that are locked in tense disputes elsewhere, with the United States taking criticism for not being tough enough against its ally Israel, whose ongoing military offensive has created a dire humanitarian crisis for the 2.3 million Palestinians in Gaza.

A key issue was the unusual language that said the Security Council “determines the imperative of an immediate and sustained cease-fire.” The phrasing was not a straightforward “demand” or “call” to halt hostilities.

The resolution reflected a shift by the United States, which has found itself at odds with much of the world as even allies of Israel push for an unconditional end to fighting.

In previous resolutions, the U.S. has closely intertwined calls for a cease-fire with demands for the release of Israeli hostages in Gaza. This resolution, using wording that’s open to interpretation, continued to link the two issues, but not as firmly.

Before the vote, Russian U.N. Ambassador Vassily Nebenzia said Moscow supports an immediate cease-fire, but he criticized the diluted language, which he called philosophical wording that does not belong in a U.N. resolution.

He accused U.S. Secretary of State Antony Blinken and U.S. Ambassador Linda Thomas-Greenfield of “deliberately misleading the international community.”

“This was some kind of an empty rhetorical exercise,” Nebenzia said. “The American product is exceedingly politicized, the sole purpose of which is to help to play to the voters, to throw them a bone in the form of some kind of a mention of a cease-fire in Gaza … and to ensure the impunity of Israel, whose crimes in the draft are not even assessed.”
