UN Panel Finds 'Reasonable Grounds' US Committed War Crimes in Iran War, Same Day Russia and China Veto Sanctions Monitoring

Since Iran routed its war-ending terms to Washington through Qatar this week, the diplomatic track and the accountability track have started moving on separate, colliding paths ahead of the UN General Assembly session opening next week in New York.

On Thursday, the UN's Independent International Fact-Finding Mission on Iran said there are "reasonable grounds" to believe US forces "committed the war crime of launching indiscriminate attacks resulting in the loss of life or injury to civilians or damage to civilian objects," according to CNBC Africa. The mission pointed to a Tomahawk missile strike on a primary school in the city of Minab that killed more than 150 people, and a separate strike on what it called a "clearly identifiable sports complex and residential area" that killed 22 civilians.

The panel said the school itself was the intended target, not collateral damage from a strike on a nearby Revolutionary Guard compound, and that it found no evidence the school was being used for military purposes.

The same mission also found Iran committed "crimes against humanity," per CNBC Africa's reporting, a detail that got far less attention than the US findings in the coverage that followed.

Washington rejected the report outright. A State Department official told CNBC Africa the US does not give credibility to the findings, arguing the UN body "pushes anti-American rhetoric and antisemitism" and "appeases repressive regimes." White House spokesperson Anna Kelly went further, telling the Associated Press: "The only party in this conflict that has committed war crimes is the Iranian regime."

The US withdrew from the UN Human Rights Council in February 2025 by executive order, with Trump officials at the time saying the council and related bodies act against American interests. That history is the backbone of Washington's argument that this mission can't be trusted as a neutral arbiter. Whether that's a fair read of this specific fact-finding panel or a blanket dismissal of an unfavorable finding is a genuinely open question the sources don't resolve. No independent US investigation, court proceeding, or charge has been announced in response to the mission's findings.

The Sanctions Fight at the Security Council

On a parallel track, Russia and China used their veto power at the UN Security Council on Thursday to block a US-drafted resolution that would have extended UN monitoring of Iran sanctions for another year, according to Breitbart. The sanctions trace back to the "snapback" mechanism France, Germany and the UK triggered in September 2025 under the original Obama-era nuclear deal, after the three European powers said Iran had "repeatedly breached its commitments."

The resolution would have passed 11-2 with two abstentions if not for the vetoes. US representative Jennifer Locetta said the council "loses its principal source of impartial, evidence-based reporting on sanctions violations," calling it a monitoring gap. The underlying sanctions stay on the books. What's gone is the independent panel of experts that tracked whether Iran is actually complying, which Russia and China had already been undercutting by voting down nominees to staff it.

The UN General Assembly Backdrop

All of this lands as Gulf states push for an opening to slow the war down. Suzanne Maloney of the Brookings Institution told Bloomberg that disruptions to Saudi Arabia's East-West pipeline and other regional infrastructure are adding pressure on Gulf economies to get the conflict off an active-combat footing.

China is positioning itself as a possible bridge. Chinese Foreign Minister Wang Yi told Iranian Foreign Minister Abbas Araghchi in Beijing on Wednesday that China is ready to play a "constructive role" and urged both sides to rebuild their negotiating channel, according to Fox News citing Iran International. China has not offered to formally mediate.

The US has approved travel for Iran's UN delegation, expected to include President Masoud Pezeshkian and Araghchi, though a State Department spokesperson said the delegation will face travel restrictions and is barred from buying luxury goods while in the US, CNBC Africa reported. Ambassador Mike Waltz said Trump will use his General Assembly address to argue Iran must be kept from a nuclear weapon and to touch on the administration's 20-point Gaza plan, and that Trump will separately meet with leaders from six Gulf Arab countries.

Meanwhile the war itself hasn't paused for the diplomacy. A tanker was hit by what the UK Maritime Trade Operations Centre called an "unknown projectile" in the Strait of Hormuz on Friday, causing a fire that was extinguished with no reported casualties. South Korean President Lee Jae Myung said Friday his country will not deploy troops to the strait, telling reporters Seoul will "carry out the minimum necessary activities" to protect its own shipping and nothing more.

Whether the UN session produces an actual US-Iran-Gulf meeting, as an MS NOW report cited by CNBC Africa suggested could happen around the General Assembly, remains unconfirmed. So does whether the war crimes finding leads anywhere beyond the diplomatic sparring it's already triggered.
