Speaking via video link from Ramallah, Abbas described the visa denial as "punitive and unlawful," noting that Iranian President Masoud Pezeshkian had been allowed to attend the summit in person under US Secret Service protection despite Iran being at war with the United States.
"We call upon the American administration to lift these sanctions and restrictions … rather than punishing the side that has chosen the path of international law and political and diplomatic action in order to guarantee its rights," Abbas said.
The US State Department said the visa was denied in part because the Palestinian Authority, which Abbas leads, had taken "actions to internationalise the Israeli-Palestinian conflict", including through proceedings in international courts.
Abbas urged the international community to stop Israel from undermining the two-state solution, accusing Israel of carrying out a "malicious colonial scheme aimed at making the lives of Palestinians more difficult in their homeland and forcing them to leave it."
He warned delegates against allowing "another Nakba" — the mass displacement of hundreds of thousands of Palestinians during Israel's founding in 1948 — and described a "genocidal war" in Gaza that Israel denies.
This year's UN summit marks a year since a bloc of countries including Australia, the United Kingdom and Canada recognised Palestinian statehood in defiance of US opposition. The UN also adopted the New York Declaration last year, expressing unwavering support for a two-state solution.
Human rights groups have documented rising violence against Palestinians by Israeli settlers in the West Bank, including killings, beatings, and damage to homes and infrastructure. The UN reports that the rate of Palestinian injuries from settler attacks has increased from one every three days in 2020 to more than three per day in 2026.
