Iran Conflict — 2026-09-18 (AM)
A UN-backed inquiry has found reasonable grounds that the United States committed war crimes in its strikes on Iran, hardening international scrutiny just as US President Donald Trump says he faces a “big decision” on the war after a tanker was hit in the Strait of Hormuz overnight. On the diplomatic front, Russia and China blocked renewal of UN monitoring of Iran’s nuclear program, while Tehran’s isolation deepened through expelled diplomats and suspended flights, and Yemen’s Houthi-Saudi frontline pushed further into Marib.
UN inquiry: US strikes on Iran, including a school, may be war crimes
Headline. The Independent International Fact-Finding Mission on Iran said it found “reasonable grounds” to believe the United States committed war crimes during its conflict with the Islamic Republic, citing mistakes that killed more than a hundred children in a strike on a school that investigators said “went beyond negligence,” plus a separate strike the same day that killed a reported 22 civilians. Al Jazeera reported a related finding on a strike on Minab, and the mission also said Iranian authorities separately committed crimes against humanity in their crackdown on recent protests, and that civilians in Iran have suffered serious human rights violations under their own government throughout the war.
Trump weighs ‘big decision’ as tanker hit in Hormuz
Headline. Trump said he now faces a “big decision” on whether to “annihilate” Iran’s leadership, warning that “anything could happen,” after a tanker was struck in the Strait of Hormuz, according to Al Jazeera’s rolling live coverage of the war. The remarks land the same day the UN inquiry’s war-crimes findings became public, adding pressure on Washington even as Trump signals further escalation remains on the table.
Russia and China veto renewal of UN Iran nuclear monitoring
Headline. Russia and China vetoed a US-backed bid to renew UN Security Council monitoring of Iran’s nuclear program, ending the Council’s watchdog panel on Iran sanctions. The New York Times said the split underscored how far world powers remain from Washington on its pressure campaign against Tehran, deepening the diplomatic rift over how to handle Iran’s nuclear file as the broader war continues.
Yemen’s war intensifies as Houthis push on Marib, deny targeting Mecca
Headline. Clashes between Iranian-backed Houthi fighters and Saudi-backed government forces have intensified near the oil-rich Marib province, the New York Times reported, as the Houthi militia advances on one of the last major government strongholds in northern Yemen. Houthi leader Abdul Malik al-Houthi separately denied his forces were targeting Mecca and vowed to protect the holy city, while Al Jazeera reported a surge in Yemeni refugees fleeing to Djibouti, which has appealed to the international community for humanitarian assistance as thousands flee the fighting.
Oil markets give up forecasting an endgame as Houthi strikes continue
Headline. JPMorgan’s oil team has abandoned trying to forecast when the Iran war will end, CNBC reported, after assuming at the war’s outset that economic redlines would force Trump into an agreement to reopen the Strait of Hormuz — a threshold Trump has since blown past. Oil prices nonetheless fell on Friday as additional Saudi crude supplies eased disruption fears, even as fresh Houthi strikes continued to threaten regional shipping.
Iran’s isolation deepens: diplomat expelled, flights suspended
Headline. Iran gave a Swedish diplomat 48 hours to leave Tehran in a retaliatory expulsion, accusing Stockholm of bowing to outside pressure, while Mahan Air said it would halt flights to neighbouring countries just over a week after the United States imposed sweeping sanctions on Iran’s aviation industry, the New York Times reported. In a partial counterpoint, the US approved visas for senior Iranian officials to attend the UN General Assembly, though Al Jazeera noted Iran’s delegation will be smaller this year amid travel restrictions and limits on luxury goods purchases.
