Iranian-linked reports say forces stopped an oil tanker at the Strait of Hormuz on Thursday, a fresh sign that Tehran’s latest closure claim is being enforced even as President Donald Trump says a U.S.-Iran agreement may be close.
The development does not prove that a peace deal has collapsed. It does show why the Strait of Hormuz remains the hardest and most dangerous part of any settlement: one side is promising a reopening after signatures, while the other is still warning ships not to move without permission.
Iranian forces reportedly stopped a tanker
The Guardian reported that Iranian state media, citing the Revolutionary Guard, said forces confronted a “violating vessel” trying to pass through the Strait of Hormuz. The vessel was described as an oil tanker and was forced to comply with what Iranian-linked reporting called a traffic prohibition law after a warning from the Guard.
The same live coverage said Iranian media also reported sounds of explosions near Sirik and Bandar Abbas, though later Iranian reporting cast some of the sounds as linked to maritime military activity rather than confirmed strikes on land.
Iran International also reported, citing Iranian state media, that explosion sounds near Sirik were connected to a confrontation with a “violating vessel” attempting to pass through Hormuz. Its update said the tanker was later made to comply after an IRGC Navy warning.
The timing is the story
The tanker report landed hours after Trump said a deal with Iran could be signed “very soon,” possibly over the weekend in Europe. Trump also said the Strait of Hormuz would open as soon as the agreement was signed.
That claim is still contested. The Associated Press reported that Trump called off new military strikes on Iran after claiming progress in negotiations, but Iranian officials had not confirmed a final agreement. AP noted that Trump has repeatedly said a deal was close during the conflict without one being completed.
The Guardian reported that Iran’s foreign ministry said no final decision had been made, even though large parts of the text may have been discussed. Iranian officials also said Tehran would not compromise on its red lines.
Hormuz is still the pressure point
Earlier Thursday, List25 covered Iran’s announcement that Hormuz was closed and Washington’s rejection of that claim. The new angle now is enforcement: Iranian-linked outlets are saying a tanker was actually stopped after entering or approaching the restricted area without coordination.
That distinction matters. A closure notice can be disputed in statements. A tanker confrontation creates a practical test for shipowners, insurers, oil buyers, and governments trying to determine whether any transit through the world’s most important energy chokepoint is still possible.
The United States is also enforcing its own blockade of Iranian ports. AP and Guardian reporting have detailed recent U.S. strikes on vessels Washington accused of violating that blockade, including attacks involving Indian-crewed tankers. That has turned both sides’ maritime pressure campaigns into a direct risk for commercial crews.
A deal may still be possible, but the sea lane is not open
The immediate takeaway is narrow but important. Trump is presenting the diplomacy as close to a signing, while Iranian officials are withholding public confirmation and Iranian-linked reports say forces are still blocking unauthorized tanker movement in Hormuz.
Until there is a signed agreement and a verified reopening process, the strait remains a live military and economic flashpoint. A single tanker encounter can move oil markets, complicate diplomacy, and raise the risk of another strike-for-strike escalation before negotiators finish the document Trump says is nearly done.
