Iran claims attack on U.S. vessel in Strait of Hormuz; U.S. rejects claim

11 Sep 2026·3 min read

On Sunday, Iran reported that it had attacked an unmanned U.S. vessel attempting to enter a restricted area in the Strait of Hormuz, according to Marine Insight. The claim came as tensions between the two nations escalated following recent military confrontations involving missile attacks and counterstrikes.

Iran's claims

Iran stated that it had attacked an unmanned U.S. vessel operating in a restricted area of the Strait of Hormuz, indicating that such entry was not permitted under Iranian maritime laws. The incident followed the U.S. military’s attack on three Iranian oil tankers and subsequent missile strikes against American warships.

Iranian parliament speaker Mohammad Bagher Qalibaf warned that Iran's response to U.S. actions would be "faster, heavier and more painful," signaling a potential shift in Iran's stance towards the United States. Additionally, Iran is reportedly planning to establish an “exclusion zone” near the Strait of Hormuz, as announced by Mohsen Rezaei, head of Iran’s Supreme National Security Council.

Rezaei stated during a televised interview that the new exclusion zone would target vessels deemed to be attempting to pass through the waterway. However, details about the implementation and enforcement mechanisms remain unclear at this time.

The U.S. response

In contrast, Capt. Tim Hawkins from U.S. Central Command dismissed Iran's claims outright, calling them a “total lie.” He asserted that the U.S. military had not been attacked as reported by Iran and stressed the importance of international cooperation in maintaining peace and security in the region.

U.S. forces have reportedly responded to Iran’s alleged attacks on five Iranian oil tankers with their own strikes, targeting two US ships and eight vessels in the Strait of Hormuz. The U.S. military claimed that incoming missiles were stopped by defensive systems without causing any damage to its vessels. Despite this, the Iranian military stated significant damage was inflicted.

A statement from Iran’s Public Relations Unit of the Islamic Revolutionary Guard Corps highlighted that the control and surveillance of the Strait of Hormuz fall under the jurisdiction of naval forces within the organization. This assertion underscores the ongoing territorial dispute between the two countries over maritime sovereignty in the area.

Global implications

The escalating tensions have raised concerns about potential disruptions to global oil supplies, as the Strait of Hormuz is a critical transit route for about 20% of the world’s seaborne crude oil. Any disruption could significantly impact energy markets and international trade flows.

Ship operators navigating through this area are advised to exercise heightened vigilance and adhere strictly to established maritime laws and guidelines, ensuring they do not enter restricted areas unless explicitly permitted by relevant authorities. The incident highlights the need for improved communication channels between regional powers to prevent misinterpretations and further escalation of conflicts.

What this means for operators

The ongoing tensions in the Strait of Hormuz present significant risks for maritime trade, particularly for ships carrying goods through this vital waterway. Operators must remain aware of any changes in navigational restrictions or enforcement actions by local authorities to avoid potentially hazardous situations.

In addition, heightened security measures and increased vigilance are recommended as a precautionary measure against potential acts of aggression. Ship operators should maintain close communication with their insurers and legal advisors to navigate the complex political landscape while ensuring compliance with international maritime regulations.
