Members of the UN Security Council failed to reach a consensus Thursday on a bid by Palestinians for full UN membership, meaning the longshot effort is now likely headed for a more formal council vote.

The Palestinians, who have had observer status at the world body since 2012, have lobbied for years to gain full membership, which would amount to recognition of Palestinian statehood.

Any request to become a UN member state must first pass through the Security Council — where Israel’s ally the United States wields a veto — and then be endorsed by the General Assembly.

In light of Israel’s offensive in Gaza, Palestinians revived a 2011 UN membership application last week, prompting the Security Council to launch a formal review process. This included the ad hoc committee that failed to reach consensus Thursday and was composed of the council’s member states.
