Iran has announced the full closure of the Strait of Hormuz, a move that sharply escalates tensions in the region and raises serious concerns about global energy supplies.
In a statement issued late Saturday, the naval wing of the Islamic Revolutionary Guard Corps (IRGC) confirmed that all previously designated safe shipping corridors through the strait have been suspended. It warned that any vessel attempting to pass through without authorization could be treated as a target.
Tehran said the decision was taken in response to ongoing US naval restrictions on Iranian ports. Iranian officials argue that the blockade violates a ceasefire understanding between the two countries and insist the strait will remain closed until the restrictions are lifted.
The announcement marks a clear shift from Friday’s position, when Iran had allowed limited passage for ships under strict conditions, including prior coordination and payment of transit fees. That arrangement has now been withdrawn.
The escalation follows reports of attacks on two vessels near the Strait of Hormuz and along the coast of Oman earlier on Saturday, with at least one incident reportedly involving Iranian gunboats.
The Strait of Hormuz is one of the world’s most critical energy routes, carrying nearly 20 percent of global oil and gas exports. Analysts warn that a prolonged shutdown could disrupt global markets and drive up fuel prices worldwide.
