Iran’s Revolutionary Guard announced on Friday, March 27, 2026, that ships linked to the United States, Israel, and their allies will not be allowed to pass through the Strait of Hormuz. In a statement, the force said three vessels from different countries attempted to cross the strait but turned back after receiving warnings from Iranian naval units. The Guard declared the waterway completely closed and warned that any attempt to violate the restriction would face severe action.

According to the statement, Iran’s ban extends beyond US and Israeli ships to include those from any nation that supports or maintains friendly relations with them. The Revolutionary Guard also said that such ships will not be permitted to enter or leave any ports associated with Iran’s jurisdiction. The announcement underscores heightened tensions in the region, with Iran asserting control over one of the world’s most strategic maritime routes.

The statement did not specify how long the closure would remain in effect or whether exceptions might be made for humanitarian or commercial purposes.
