TEHRAN, April 18, 2026 Iran has abruptly reversed its position on the Strait of Hormuz, warning vessels against movement in the Persian Gulf and threatening to target those approaching the critical waterway, just a day after declaring it fully open to commercial traffic.
IRGC Issues Stark Warning
The Islamic Revolutionary Guard Corps (IRGC) military command spokesman issued a sharp warning, stating that the Strait of Hormuz would remain under "strict control" unless the U.S. ends restrictions on Iranian vessels. The statement, reported by Tehran’s Fars News Agency, emphasized that the waterway’s status would not change until the U.S. allows "complete freedom of movement for vessels from Iranian origin to destination and from destination to Iranian origin."
The IRGC further escalated tensions by declaring that any vessel moving from anchorage in the Persian Gulf or the Sea of Oman would be considered "cooperation with the enemy." "We warn that no vessel of any kind should move from its anchorage in the Persian Gulf and the Sea of Oman, and approaching the Strait of Hormuz will be considered cooperation with the enemy, and the offending vessel will be targeted," the statement said.
US Naval Blockade Remains in Place
The sudden shift in Iran’s stance comes just a day after Tehran announced the Strait of Hormuz was fully open to commercial shipping. U.S. President Donald Trump welcomed the initial announcement but reaffirmed that the U.S. naval blockade of Iranian ports along the strait "is going to remain."
