The 15-member council is due to vote at 3pm on Friday in New York on a draft resolution that recommends to the 193-member UN General Assembly that "the state of Palestine be admitted to membership of the United Nations," diplomats said.

A council resolution needs at least nine votes in favour and no vetoes by the United States, United Kingdom, France, Russia or China to pass.

Diplomats say the measure could have the support of up to 13 council members, which would force the US to use its veto.

Council member Algeria, which put forward the draft resolution, had requested a vote for Thursday afternoon to coincide with a Security Council meeting on the Middle East, which is due to be attended by several ministers.

The United States has said that establishing an independent Palestinian state should happen through direct negotiations between the parties and not at the United Nations.

"We do not see that doing a resolution in the Security Council will necessarily get us to a place where we can find ... a two-state solution moving forward," US ambassador to the UN Linda Thomas-Greenfield said on Wednesday.

The Palestinians are currently a non-member observer state, a de facto recognition of statehood that was granted by the 193-member UN General Assembly in 2012.

But an application to become a full UN member needs to be approved by the Security Council and then at least two-thirds of the General Assembly.

The UN Security Council has long endorsed a vision of two states living side by side within secure and recognised borders.

Palestinians want a state in the West Bank, east Jerusalem and Gaza Strip, all territory captured by Israel in 1967.

Little progress has been made on achieving Palestinian statehood since the signing of the Oslo Accords between Israel and the Palestinian Authority in the early 1990s.

The Palestinian push for full UN membership comes six months into a war between Israel and Palestinian Hamas militants in Gaza, and as Israel is expanding settlements in the occupied West Bank.

Israel's UN ambassador Gilad Erdan said earlier this month that "whoever supports recognising a Palestinian state at such a time not only gives a prize to terror but also backs unilateral steps which are contradictory to the agreed-upon principle of direct negotiations".

A Security Council committee on the admission of new members - made up of all 15 council members - met twice last week to discuss the Palestinian application and agreed to a report on the issue on Tuesday.

"Regarding the issue of whether the application met all the criteria for membership ... the Committee was unable to make a unanimous recommendation to the Security Council," the report said, adding that "differing views were expressed."

UN membership is open to "peace-loving states" that accept the obligations in the founding UN charter and are able and willing to carry them out.

Hamas fighters triggered the war in Gaza by attacking southern Israel on October 7, killing 1200 people and capturing 253 hostages according to Israeli tallies.

Inside Gaza, Israel has launched a massive air and ground assault, with nearly 34,000 people confirmed killed, according to Palestinian medics, and thousands of others feared dead, still lost among the ruins.

Apart from a single week of ceasefire in November when around half of the hostages were freed, diplomats have so far failed to hammer out terms for a truce.

This month, Israel abruptly pulled most of its troops out of southern Gaza, site of most of the heaviest fighting since the start of the year.

Fighting in recent days has been focused in central Gaza, in the Nuseirat camp north of Deir al-Balah, one of the few areas that Israeli troops have yet to storm.
