Iran issued a fresh warning to Britain and France on Saturday after the two European powers said Oman had agreed to work with them to keep the Strait of Hormuz safe for navigation.
The warning adds a new layer to the Iran crisis because the strait is not just a military flashpoint. It is one of the world’s most important energy routes, and control over how ships pass through it has become a central dispute in talks aimed at stabilizing the region.
Iran pushes back on the European plan
CBS News reported that Iranian Deputy Foreign Minister Kazem Gharibabadi issued what he called a “serious warning” to the United Kingdom and France after they pledged to work with Oman on safe navigation through the Strait of Hormuz.
Gharibabadi said the strait was “not a theater for the military display of extra-regional powers” and warned that Iran would treat outside military activity in the waterway with sensitivity, according to the CBS live report.
The comments followed a joint statement published by the U.K. government on Friday from Prime Minister Keir Starmer and French President Emmanuel Macron. The statement called the Strait of Hormuz “a vital artery for the global economy” and said restoring safe transit for ships of all nations was a matter of global concern.
The statement said Oman had agreed to work with Britain and France to ensure that its sovereign territorial waters are safe for navigation. It also said the U.K. and France stood ready to deploy the wider Multinational Military Mission to support freedom of navigation in the strait.
Hormuz is now the diplomatic pressure point
The escalation comes after Iran separately warned oil tankers and commercial ships to use approved routes in the Strait of Hormuz or face a “forceful response,” according to the Associated Press. That warning sharpened concerns among shipping operators already navigating a fragile pause in fighting and a volatile regional security environment.
The immediate issue is who gets to define safe passage through the narrow waterway. Britain, France, Oman and the United States are emphasizing freedom of navigation and open commercial transit. Iran is signaling that it expects a direct role in managing the route and is warning outside powers not to turn the strait into a military showcase.
That makes the latest warning more than rhetoric. It shows that maritime rules in Hormuz could become one of the hardest parts of any broader U.S.-Iran settlement, especially while nuclear, sanctions and regional-security issues remain unresolved.
Talks remain paused during Khamenei funeral events
The warning also lands during Iran’s dayslong funeral ceremonies for slain former Supreme Leader Ayatollah Ali Khamenei. CBS reported that U.S.-Iran talks are paused during the funeral period, with mediators expected to resume scheduling after the commemorations.
That pause matters because it leaves the Hormuz dispute developing in public while negotiators are offstage. If shipping disruptions continue or European military support becomes more visible, the waterway could quickly become the first major test of whether the current ceasefire diplomacy has any staying power.
For now, the clearest takeaway is this: Oman, Britain and France are trying to frame Hormuz as an international navigation problem, while Tehran is framing it as a regional sovereignty issue. That clash is now moving to the center of the Iran crisis.
