Iran’s main military command, Khatam al-Anbiya Central Headquarters, said Thursday that no vessel can safely transit the Strait of Hormuz without permission from Iranian authorities, local media reported.

A spokesman for the headquarters rejected US claims that ships were passing normally through the strategic waterway, saying the strait remained under the “complete management and control” of Iran. He said commercial ships and tankers would require the permission and supervision of Iranian armed forces to transit safely.

Iranian Foreign Minister Sayed Abbas Aragchi also accused the US of miscalculating its strategy toward Iran, particularly over the Strait of Hormuz. In a post on X, he warned that what he called “fake intelligence” could lead to further miscalculations.

The Iranian statements came after US President Donald Trump claimed on Wednesday that the United States had “total control” over the Strait of Hormuz and indicated that Washington intended to maintain its position there.

Trump also described the US naval blockade as a “wall of steel,” saying Iran had no ability to challenge it. However, he did not provide operational details about the blockade, including how long it would remain in place or what conditions would lead to its termination.

The Strait of Hormuz is one of the world’s most strategically important waterways and a major route for global energy shipments. The competing claims by Tehran and Washington have heightened concerns over shipping security and the potential impact on international trade and energy markets.

The latest developments come amid continuing tensions between Iran and the United States, with control and access to the Strait of Hormuz emerging as a major point of contention.
