The Joint Maritime Information Center said that the U.S. has established an “enhanced security area” to the south of usual shipping routes to support transit.
It said vessels should consider routing via Oman territorial waters as usual routes should be considered “extremely hazardous due the presence of mines that have not been fully surveyed and mitigated.”
Iran’s Navy shared a new map of what it said was the area of the strait under its control, though it was not clear whether this represented any change.
The map shows a line between Iran’s Qeshm island and the United Arab Emirates’ Umm al Quwain emirate. In the east, the area stops at a line between Iran’s Mount Mobarak and the U.A.E.’s Fujairah.via FARS

Maritime movements that are inconsistent with Tehran’s “declared principles” will face serious risks, said Hossein Mohebbi, a spokesman for Iran’s Revolutionary Guard. “Violating vessels will be stopped with full force,” he said, according to the semi-official ISNA news agency.
Any American interference in the strait will be considered a “violation of the ceasefire” currently in place between Tehran and Washington, warned Ebrahim Azizi, the head of parliament’s National Security and Foreign Policy Committee, in a post on X late Sunday.
Hundreds of ships and thousands of crew members have been stranded in the area since Iran launched attacks and threatened shipping in the wake of the joint U.S.-Israeli assault more than two months ago.
Many of them are running low on food and other necessities, Trump said, calling his move to free them up a “humanitarian gesture” by the U.S.
Two ships were attacked in the strait this weekend, the British military’s United Kingdom Maritime Trade Operations Center said.
Trump’s announcement was done without industry coordination, leaving shipping companies scrambling for details, industry figures said.
