The UN Human Rights Council on Friday demanded a halt in all arms sales to Israel, , which has killed more than 33,000 people.
The resolution — which passed with 28 of the council's 47 member states voting in favour, six opposed and 13 abstaining — marked the first time the United Nations' top rights body has taken a position on the bloodiest-ever war to beset the besieged Palestinian territory.
Meirav Eilon Shahar, Israel's ambassador to the UN in Geneva, slammed the resolution as "a stain for the Human Rights Council and for the UN as a whole".
The strongly worded text called on countries to "cease the sale, transfer and diversion of arms, munitions and other military equipment to Israel... to prevent further violations of international humanitarian law and violations and abuses of human rights".
It stressed that the International Court of Justice ruled in January "that there is a plausible risk of genocide" in Gaza.
Friday's resolution, which was brought forward by Pakistan on behalf of all Organisation of Islamic Cooperation (OIC) member states except Albania, also called for "an immediate ceasefire" and "for immediate emergency humanitarian access and assistance".
'Stop this genocide'
"We need you all to wake up and stop this genocide, a genocide televised around the world," Palestinian ambassador Ibrahim Mohammad Khraishi told the council before the vote.
Shahar meanwhile told council members that "a vote yes is a vote for Hamas".
Key ally, Washington, heeded Israel's call to vote no, as did Germany, Argentina, Bulgaria, Malawi and Paraguay.
US ambassador Michele Taylor agreed that "far too many civilians have been killed in this conflict and that every civilian death is a tragedy", acknowledging that "Israel has not done enough to mitigate civilian harm".
But she said Washington could not support the text, which she said contained "many problematic elements", including its failure to specifically condemn Hamas and its 7 October attacks.
Friday's vote came after the UN Security Council in New York last week also finally passed a resolution calling for a ceasefire, thanks to an abstention from Washington.
The 7 October attack, in which 1,200 people were killed and more than 240 taken hostage, was a significant escalation in the long-standing conflict between Israel and Hamas.
Since then, Israel's relentless military assault has killed at least 33,091 people, according to the health ministry in Gaza.
While the rights council resolution did not name Hamas, it did condemn the firing of rockets at Israeli civilian areas and demanded "the immediate release of all remaining hostages".
The text, which was revised late on Thursday removing several references to genocide, continued to express "grave concern at statements by Israeli officials amounting to incitement to genocide".
It warned in particular "against any large-scale military operations in the city of Rafah" in the south of the densely populated Gaza Strip, where well over one million civilians are sheltering, warning of "devastating humanitarian consequences".
The resolution also condemned "the use of starvation of civilians as a method of warfare in Gaza", where the UN has warned that famine is looming.
It called on UN war crimes investigators — tasked with probing the rights situation in the Occupied Palestinian territories even before October 7 — to look into all "direct and indirect transfer or sale of arms, munitions, parts, components and dual use items to Israel ... and "analyse the legal consequences of these transfers".
