On Thursday, 29 October 2026, a small boat attached two limpet mines to the Panama-flagged tanker Louise 1 in the Strait of Hormuz, causing an engine-room fire and temporarily disabling her. The crew was safe, there was no environmental impact, the fire was extinguished, and the vessel continued to its next port.
On Friday morning, 30 October, Iran’s Revolutionary Guards Navy said two oil tankers were stopped south of Hormuz after ignoring radio warnings and using what Iran called an unauthorised route. Iran’s Army Navy separately said it destroyed an enemy unmanned surface vessel in the eastern Strait early Friday, and that two tankers with tracking systems off hit sea mines, were damaged and caught fire.
On Thursday evening, Yemen’s Iran-aligned Houthis claimed six missile and drone operations against Saudi Arabia: Ras Tanura refinery, Aramco Abqaiq, Rabigh refinery, King Khalid International Airport in Riyadh, King Fahd International Airport in Dammam, and a military mobilisation headquarters in Najran.
Oil spiked on the news. Brent was 115.74 dollars at 0122 GMT on Friday, 30 October, with WTI at 102.72 dollars, and later Friday Brent was reported up 2.3 percent to 117.56 dollars by 1150 GMT.
Why the story travels is that this is the first successful limpet-mine attack in Hormuz since the United States war with Iran began in February 2026, a September attempt did not detonate, plus a claimed direct hit on a United States vessel, simultaneous claimed strikes on Saudi Arabia’s biggest refinery and two international airports, and oil over 115 dollars, a direct hit on United States petrol prices days before the 3 November midterms.
What is confirmed is the Louise 1 limpet-mine attack, engine-room fire, crew safe, and first successful limpet use since February, according to Reuters, three maritime security sources and UK Maritime Trade Operations. The Iranian statements themselves are confirmed, and the Houthi claim of six attacks, plus Saudi coalition confirmation of only two Riyadh intercepts, with shrapnel wounding one Saudi citizen in Riyadh, are confirmed as statements.
What is not confirmed is that the destroyed unmanned vessel was American, or that the United States military confirmed any loss. Reuters explicitly said there was no immediate confirmation from the United States military. Who planted the Louise 1 limpet mines was not immediately clear, and Saudi authorities did not confirm five of the six Houthi targets. Sources also differ on tanker count, two versus three, so this article does not merge those counts into one confirmed total. No United States retaliatory strikes have been confirmed in these sources.
