The Persian Gulf Strait Authority (PGSA), Iran’s new body set up to manage the Strait of Hormuz, has registered its account on X and said any passage through the waterway without permission from it “will be considered illegal”, Al Jazeera reports.

“Navigation within the introduced boundaries of the Strait of Hormuz, which were previously determined by the Armed Forces and authorities of the Islamic Republic of Iran, is contingent upon full coordination with these entities,” its statement says, “and passage without permission will be considered illegal.”
