The UN Security Council will vote Monday on a resolution endorsing US President Donald Trump’s comprehensive Gaza ceasefire plan, diplomats said Saturday, as Washington warned of a “real human cost” if the body doesn’t back the proposal.

US Ambassador to the UN Mike Waltz said failure to endorse the plan, which would deliver Gaza to an International Stabilization Force (ISF) and an apolitical Palestinian administration overseen by a Trump-chaired Board of Peace, amounted to support for Hamas and for war.

“Any refusal to back this resolution is a vote either for the continued reign of Hamas terrorists or for the return to war with Israel, condemning the region and its people to perpetual conflict,” wrote Waltz in the Washington Post on Friday.

“Every departure from this path, be it by those who wish to play political games or to re-litigate the past, will come with a real human cost,” Waltz wrote.

Last week, the US officially launched negotiations within the 15-member Security Council on a draft resolution that would follow up on Israel and Hamas’s October 9 ceasefire-hostage agreement.

That agreement has seen Israel stage an initial withdrawal in Gaza and Hamas release the last 20 living hostages abducted in its onslaught in southern Israel on October 7, 2023, which sparked the war in Gaza, as well as the remains of 25 out of 28 deceased hostages still in Gaza when the deal was reached.

A draft of the proposed Security Council resolution, which was obtained and verified by The Times of Israel last week, included the entirety of Trump’s 20-point plan, which Prime Minister Benjamin Netanyahu also endorsed in a joint press conference with the president in September.

The draft authorized member states working with the Board of Peace to “establish a temporary International Stabilization Force,” and indicated the board’s mandate would run through the end of 2027. Countries that expressed willingness to contribute troops to the ISF have said they would need a UN resolution enshrining the force.

The ceasefire plan included in the draft also says that, as Gaza is demilitarized and rebuilt and the West Bank-based Palestinian Authority “faithfully” reforms itself, “the conditions may finally be in place for a credible pathway to Palestinian self-determination and statehood.”

Diplomatic sources have noted there are some questions about the US text, particularly regarding the absence of a monitoring mechanism by the Council, the role of the PA and specifics of the ISF’s mandate.

In a joint statement arranged by the US on Friday, multiple countries working toward an end to the Gaza conflict voiced backing for Washington’s UN Security Council resolution.

The statement, supported by Qatar, Egypt, the United Arab Emirates, Saudi Arabia, Indonesia, Pakistan, Jordan and Turkey, noted that the process “offers a pathway to Palestinian self-determination and statehood.”

Friday’s joint statement appeared to go further than the text of the plan by not leaving the question of a political horizon up for debate, possibly meeting a demand by signatories to the statement.

Despite the language of the 20-point plan, Trump has gone on the record in recent weeks saying that he hasn’t even decided whether he’ll back a two-state solution. The Israeli government is vehemently opposed to the two-state framework.

Friday’s statement also came as the US was said to be pressing Saudi Arabia to normalize ties with Israel. As a condition for moving forward on establishing official relations, Riyadh has insisted that Israel commit to Palestinian statehood.

Meanwhile, Russia — a veto-wielding member of the UN Security Council — circulated a competing draft resolution to council members that does not authorize the creation of a board of peace or the immediate deployment of an international force in Gaza, according to the text seen Friday by AFP.

The Russian version welcomes “the initiative that led to the ceasefire,” but does not name Trump. It also only calls on the UN secretary-general to submit a report that addresses the possibilities of deploying an international stabilization force in war-ravaged Gaza.

The Russian UN mission said in a statement that its alternative proposal differed by recognizing the principle of a “two-state solution for the Israeli-Palestinian settlement.”

“Unfortunately, these provisions were not given due regard in the US draft,” it said.

UN: Heavy rains make Gaza ‘even more desperate’

Meanwhile, Gaza was hit by heavy rain over the weekend as the first major storm hit the area.

UNRWA, the UN agency for Palestinian refugees, said in a statement on X that the rain in Gaza was “making conditions even more desperate.”

“Families [are] taking shelter anywhere they can, including in makeshift tents. Shelter supplies are urgently needed,” said the statement. “UNRWA has those supplies to help people get through winter. Let us bring them in.”

The UN and Israel have long accused each other of impeding the delivery of aid in Gaza.

The UN Office for the Coordination of Humanitarian Affairs (OCHA) said Friday that it distributed some 1,000 new tents in Gaza on Thursday, as well as winter clothes, about 7,000 blankets and 15,000 tarpaulins over the past week in preparation for winter.
