On Saturday (May 30, 2026), Iran's Khatam al-Anbiya Headquarters announced that all ships and oil tankers transiting the Strait of Hormuz must strictly follow maritime routes designated by Tehran and obtain prior clearance from the Islamic Revolutionary Guard Corps (IRGC) Navy. In an official statement, the headquarters warned that any violation of these transit regulations would pose a severe risk to navigational security. It further emphasized that any military intervention by foreign vessels in the management of the strait would make them direct targets. The statement affirmed that the Iranian Armed Forces are managing the strait with full authority, signaling an intensification of security measures in one of the world's most critical strategic corridors for global energy trade.
