In a statement issued on Thursday, the IRGC’s naval forces said the four vessels targeted on Wednesday were involved in what Iran described as the illegal transfer of oil. The attacks reportedly set the ships ablaze, although the statement provided no detailed information about their identities, ownership or the extent of the damage.
The Iranian military also reported that three additional vessels had been caught in mine explosions west of the Strait of Hormuz. Details about the circumstances of those incidents, including whether anyone was injured or killed, were not immediately available.
The claims could not be independently verified from the information provided, and further details about the incidents remain unclear.
Iran warns US over military activities
The IRGC used its statement to issue a warning to the United States, threatening larger-scale attacks against American military bases in the region if Washington continued what Tehran described as provocative activities.
The warning comes amid heightened tensions between Iran and the United States, with the Strait of Hormuz once again emerging as a potential flashpoint in the wider conflict.
According to the report, attacks in the strategically important waterway have occurred regularly since joint US-Israeli strikes against Iran on 28 February. The latest incidents add to concerns over the safety of commercial shipping and the potential disruption of international energy supplies.
Neither the full circumstances surrounding Wednesday’s reported attacks nor the US response to the IRGC’s latest warning were detailed in the account.
A vital route for global energy supplies
The Strait of Hormuz is one of the world’s most important maritime passages for energy shipments. Connecting the Persian Gulf with the Gulf of Oman and the wider Arabian Sea, it serves as a major export route for crude oil and liquefied natural gas from several Gulf producers.
Saudi Arabia, Iraq, Kuwait, the United Arab Emirates and Qatar are among the countries whose energy exports rely on maritime routes in the region. Any prolonged disruption to shipping through the strait could therefore have consequences far beyond the Middle East.
Military attacks, mine explosions and threats to commercial vessels can force shipping companies to reassess the risks of operating in the area. Rising security concerns may also increase insurance premiums and transport costs, while delays or interruptions to energy shipments could place upward pressure on international oil prices.
For countries that depend heavily on imported fuel, sustained disruption could translate into higher import bills and additional pressure on domestic energy markets. The extent of any such impact would depend on the duration and severity of the disruption, as well as developments in the wider international oil market.
Diplomatic efforts failed to prevent renewed confrontation
The report said the United States and Iran signed a memorandum of understanding in June in an effort to end the conflict and reopen the Strait of Hormuz. The arrangement was also expected to pave the way for discussions on Iran’s nuclear programme.
However, the understanding collapsed after a short period, and the two countries became embroiled in renewed confrontation over the strategic waterway.
The failure of the diplomatic initiative has raised fresh questions about the prospects for de-escalation. Although negotiations had offered a possible route towards reducing tensions, the latest reported attacks suggest that the security situation remains volatile.
The Strait of Hormuz is particularly sensitive because even a limited incident can prompt concerns about the safety of vessels travelling through the narrow passage. A sustained escalation could affect shipping schedules, energy exports and confidence in the security of regional trade routes.
For now, important details surrounding the reported incidents remain unconfirmed, including the names of the seven vessels, the scale of the damage and the precise circumstances of the alleged attacks. Further information will be needed to establish the full impact of the incidents.
The immediate concern is whether the latest developments will lead to further military action or renewed diplomatic efforts. With the waterway playing a central role in global energy trade, any prolonged escalation could carry significant economic and security implications well beyond the region.
