The U.S. State Department announced Friday it will deny and revoke visas for Palestinian leadership ahead of next month’s United Nations General Assembly in New York.

The State Department did not specify in a press release which Palestinian officials will be barred from traveling to the United States. But in the past, top Palestinian leaders — including Palestinian Authority President Mahmoud Abbas — have traveled to New York for the U.N. General Assembly.

“Before they can be taken seriously as partners for peace, the PA and [Palestine Liberation Organization] must repudiate terrorism, lawfare campaigns at the [International Criminal Court] and [International Court of Justice], and the pursuit of unilateral recognition of statehood,” State Department Principal Deputy Spokesperson Tommy Pigott said in a statement Friday.

He added that the U.S. “remains open to re-engagement should the PA/PLO demonstrably take concrete steps to return to constructive engagement.”

The release noted that State will continue issuing visas for Palestinian diplomats staffing the Palestinian Authority mission before the United Nations, in alignment with a treaty governing the U.N. headquarters in New York.

This agreement has allowed U.S. adversaries, namely Iran and North Korea, to maintain staffed missions in New York to represent their interests before the U.N. even if their governments do not have diplomatic relations with Washington.

But government officials outside of those missions could still see their travel to New York blocked.

Riyad Mansour, the Palestinian ambassador to the U.N., said Friday, “We will see exactly what it means and how it applies to any of our delegation, and we will respond accordingly.”

Spokesperson Farhan Aziz Haq said the United Nations is following up with the State Department on the announcement.

The decision comes as Israel faces mounting pressure from several U.S. allies to address the humanitarian crisis in Gaza.

And the announced visa revocations are the latest reprisal against Palestinian leadership amid a push led by U.S. allies to recognize a Palestinian state during this year’s United Nations High-Level Week, when world leaders gather in New York to kick off the ensuing year’s business at the international forum.

France, Australia and the United Kingdom are among the major U.S. allies now backing Palestinian statehood in light of Israel’s ongoing war against militant group Hamas in the Gaza Strip.

The effort is not expected to succeed since the U.S. has veto power at the United Nations Security Council and can block any bid for Palestine to be recognized as a full voting member of the United Nations, but it could prove to be a symbolic rebuke of the Trump administration.

The State Department last month announced sanctions against two groups, the Palestine Liberation Organization and Palestinian Authority; the groups are the main governing and political forces acting on behalf of Palestinians in the West Bank and recognized as the representatives of Palestinian interests at global fora. The sanctions were issued under similar pretenses that the groups had ties to terrorism.

Critics have previously slammed those moves as retaliation for the push for Palestinian statehood and as attempts from Washington to undermine what could be an embarrassing moment for the Trump administration in New York next month.

President Donald Trump will address the U.N. General Assembly on Sept. 23, White House press secretary Karoline Leavitt said Thursday. The Trump administration has resisted calls to recognize a Palestinian state ahead of the General Assembly.
