The United States said navy destroyers and US-flagged merchant ships sailed through the Strait of Hormuz on Monday, a transit Tehran’s forces framed as a direct violation of its warnings.
US Central Command said the two US-flagged merchant vessels "successfully transited through the Strait of Hormuz" after what Iranian state media called an exchange in which Iran’s military reported it had hit a US destroyer — a claim the US military denied.
The Iranian military said the Army Navy "issued a warning and fired warning shots along the route of the hostile enemy destroyers" and that the destroyers "turned off their radars before approaching the strait and were detected immediately after reactivating them." It also said the destroyers received a radio warning "regarding the dangers of violating the ceasefire" and that an explicit warning was sent saying "any attempt to enter the Strait of Hormuz would be considered a violation of the ceasefire and would be met with a response from naval forces." The statement added: "This is a serious warning... the Strait of Hormuz remains closed."
In Washington, the US military denied Iranian state media’s report that a US warship had been struck. The public dispute followed comments by former President Donald Trump, who said the US military would "guide" ships through the Strait of Hormuz after helping stranded vessels move out of the shipping lane.
The immediate numbers underline why the confrontation matters: an estimated 20,000 seafarers on roughly 2,000 ships have been affected since the conflict began on February 28, when the war started, according to tracking and maritime industry estimates. The Strait of Hormuz is a crucial shipping passage and a major transport route for oil, gas and fertiliser, and interruptions there ripple through global trade.
The competing accounts are sharp and specific. Iranian state media reported that its forces had hit a US destroyer trying to enter the strait, while the US military categorically denied any of its vessels had been struck. US Central Command’s statement that the merchant vessels "successfully transited through the Strait of Hormuz" stands at odds with Iran’s depiction of shots fired in the path of those same ships.
Questions about independent confirmation remain. A popular vessel-tracking service did not show vessels matching the description of the two US-flagged merchant vessels at the time the tracking tool was checked, but maritime experts note that vessels can turn off AIS transmissions and may also spoof their positions on tracking platforms, complicating outside verification.
There is an operational gap between the sides’ public positions that creates real risk. Iran says any ship wanting to cross the Strait will need its permission; the United States has committed to escorting and protecting ships that it considers free to navigate. Those mutually exclusive stances — permission versus passage — mean a routine transit can quickly become a flashpoint if warnings are ignored or interpreted as violations.
The most consequential near-term question is whether these dueling rules of the road will produce a real military clash. Both sides have already signalled readiness to enforce their claims: Iran with warnings, fired shots and public pronouncements that the strait "remains closed," and the United States by directing naval assets to shepherd vessels and publicly denying any losses when Tehran said a destroyer had been hit.
Absent a negotiated, verifiable arrangement on who controls access, the pattern of contested transits is likely to continue. That will leave merchant crews, whose movement and safety have been upended for weeks, exposed to the confusion and danger created by overlapping claims over one of the world’s busiest passages.
