Iran Makes Sweeping Strait of Hormuz Power Move as US-Iran Gulf Tensions Deepen

Iran has expanded its claimed military oversight around the Strait of Hormuz, escalating tensions in the Gulf as the US intensifies maritime operations and regional diplomatic efforts continue.

Tehran unveils expanded military control claims over strategic waters while tanker incidents, US operations and diplomacy intensify pressure across the Gulf

A new flashpoint has emerged in the Gulf after Iran announced a significant expansion of the maritime zone it says falls under its military supervision around the Strait of Hormuz, one of the world's most critical energy and trade routes.

The announcement comes at a highly sensitive moment marked by increasing confrontations at sea, diplomatic maneuvering, and uncertainty surrounding relations between Tehran and Washington.

According to a newly released map from Iran's recently established Persian Gulf Strait Authority, Iranian armed forces now claim oversight across more than 22,000 square kilometres (8,800 square miles) in and around the strategic waterway.

The designated area stretches beyond Iranian waters and overlaps with maritime areas associated with Oman and the United Arab Emirates, adding another layer of tension to already fragile regional relations.

Iranian officials also indicated that ships crossing the strait would now need approval and coordination through the new authority before proceeding through the passage.

The announcement immediately drew criticism from Gulf states.

Anwar Gargash, diplomatic adviser to the UAE president, rejected Tehran's position and accused Iran of attempting to create a new regional reality following military setbacks.

He said efforts aimed at controlling the Strait of Hormuz or interfering with UAE maritime rights amounted to "nothing but fragments of dreams."

For years, the United States and several Gulf partners have opposed attempts by Iran to establish unilateral control over the strategic route. Washington has repeatedly instructed vessels operating in the region not to follow Iranian restrictions.

The Strait of Hormuz carries enormous geopolitical significance because it serves as one of the world's main channels for energy exports and international shipping traffic. Any instability in the area has the potential to create ripple effects across global markets.

International maritime rules under the United Nations Convention on the Law of the Sea provide ships with rights of passage through foreign territorial waters, although Iran has not formally ratified the agreement.

Adding to growing concerns, media outlets linked to Iran's Islamic Revolutionary Guard Corps released video footage this week claiming to show what they described as a "punishment" strike targeting a tanker moving through the strait.

Analysis reportedly matched features of the vessel shown in the footage with Barakah, a Liberian-flagged tanker whose operators said it had been hit by unidentified projectiles earlier this month.

The maritime tensions unfolded alongside another major development in nearby waters.

US Central Command said American forces boarded an Iran-bound oil tanker identified as Celestial Sea in the Gulf of Oman after suspecting it of violating the US blockade involving Iranian ports.

Video released by the military showed marines descending from helicopters onto the vessel during the operation.

According to maritime risk management company Vanguard, the vessel was later released after inspections were completed and the crew was instructed to alter its route.

Shipping data later showed Celestial Sea listing Oman's port of Duqm as its destination.

US Central Command also stated that since blockade measures began on 13 April, American forces have redirected 94 commercial vessels and disabled four ships.

At the same time, diplomatic activity continues behind the scenes.

US President Donald Trump said earlier this week that he postponed a planned military operation against Iran after Gulf leaders requested additional time for negotiations.

According to Trump, leaders from Qatar, Saudi Arabia and the United Arab Emirates urged restraint as talks progressed.

Meanwhile, Pakistan's military chief Asim Munir is reportedly in Tehran for discussions intended to support mediation efforts between Iran and the United States.

Iranian officials have also confirmed that proposals from Washington aimed at ending the conflict are currently under review.

Despite signs of diplomacy, Trump indicated military action remains an option if negotiations fail.

"Believe me, if we don't get the right answers, it goes very quickly. We're all ready to go," he said.

As military positioning and diplomatic efforts continue simultaneously, the Strait of Hormuz once again finds itself at the center of a high-stakes geopolitical contest with global consequences.
