Iran's health minister reported 18 killed and 108 wounded that day, including victims of a strike on a wedding in Sirik. Trump said Iran 'will be hit again at a much harder and higher level' and that he preferred 'almost total control of the Hormuz Strait' to negotiations. The House voted 220–204 on September 15 to end US hostilities; on September 24 the Senate rejected the House measure 49–50 — the 14th Senate war powers vote since February. On September 26 Trump rejected an Iranian seven-day roadmap to reopen the strait and end the war, saying Iran was 'losing so badly.'","summary":"September 2026 saw the US resume heavy strikes on Iran, Trump threaten to strike 'much harder,' Congress come within one Senate vote of ordering an end to unauthorized hostilities, and Trump reject an Iranian truce proposal — leaving a seven-month war with no congressional authorization and no exit.","category":"military-overreach","severity":"critical","ongoing":true,"sources":[{"url":"https://www.stripes.com/theaters/middle_east/2026-09-01/us-forces-strike-iran-targets-22721692.html","title":"US forces strike IRGC targets in Iran, CENTCOM says","publisher":"Stars and Stripes"},{"url":"https://www.aljazeera.com/news/2026/9/1/us-military-says-launching-new-attacks-on-iran","title":"Iran claims attacks on Bahrain, Jordan, Iraq after US strikes kill 11","publisher":"Al Jazeera"},{"url":"https://www.nbcnews.com/world/iran/us-launched-large-powerful-strikes-iran-trump-says-rcna595581","title":"Tehran targets U.S. allies in Gulf after U.S. launched 'large and powerful' strikes on Iran","publisher":"NBC News"},{"url":"https://www.militarytimes.com/news/your-military/2026/09/03/iran-war-escalation-raises-concern-over-civilian-death-toll/","title":"Iran war escalation raises concern over civilian death toll","publisher":"Military Times / Reuters"},{"url":"https://www.aljazeera.com/news/2026/9/16/us-house-votes-to-end-iran-war-7-republicans-join-in-favour","title":"US House votes to end Iran war, 7 Republicans join in favour","publisher":"Al Jazeera"},{"url":"https://www.cbsnews.com/news/senate-iran-war-powers-resolution-vote/","title":"Iran war powers measure falls short in Senate, despite new GOP support","publisher":"CBS News"},{"url":"https://www.stripes.com/theaters/us/2026-09-24/senate-votes-down-resolution-iran-war-22954545.html","title":"Senate votes down attempt to halt Iran war","publisher":"Stars and Stripes"},{"url":"https://www.aljazeera.com/news/2026/9/27/better-deal-whats-behind-trumps-rejection-of-irans-truce-offer","title":"'Better deal': What's behind Trump's rejection of Iran's truce offer?","publisher":"Al Jazeera"}],"draft":false,"status":"published","tags":["Iran war","war powers","Strait of Hormuz","Congress","ceasefire","Larak Island"],"relatedEntries":["iran-war-sirik-wedding-strike","iran-war-ceasefire-collapse-july2026","iran-war-crime-of-aggression","iran-war-naval-blockade","strait-of-hormuz-crisis"],"timeline":[{"date":"2026-08-30","title":"US strikes Larak Island","summary":"The US strikes Larak Island in the Strait of Hormuz; Iran fires ballistic missiles and drones at bases hosting US forces the next day, saying it is retaliating (Stars and Stripes)."},{"date":"2026-09-01","title":"'Large and powerful' strikes on Iran's coast","summary":"CENTCOM strikes air defense sites, radar systems, maritime assets, mine-laying capabilities and communications sites in Sirik, Konarak, Bandar Abbas, Jask, Asaluyeh, Ahvaz and Qeshm.
