Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy says two oil tankers exploded and caught fire after striking naval mines while attempting to cross the Strait of Hormuz using what Tehran described as an unauthorised route. The force accused the vessels of switching off their radar and positioning systems in an attempt to make the passage without being detected, adding another flashpoint to the growing confrontation over control of one of the world’s most important energy shipping corridors.

In a statement carried by Iranian state media on Saturday, November 14, the IRGC Navy said the tankers were “secretly” attempting to transit the southern part of the strait when they struck mines. The statement said one of the vessels was a supertanker, but did not disclose either ship’s name, flag, ownership, cargo destination or the extent of the damage. The claims were reported by AFP via Channel NewsAsia and Reuters.

Iran Says Tankers Ignored Its Navigation Restrictions

Tehran has increasingly asserted authority over vessel movements through the Strait of Hormuz since the war with the United States began in February 2026. Iranian authorities say ships must coordinate with their maritime traffic control system and follow routes approved by them. The IRGC Navy warned shipowners and shipping companies against attempting to pass through the waterway without authorisation.

The accusation that the tankers disabled tracking and positioning equipment is significant because commercial vessels normally use identification and tracking systems to communicate their identity, position and movement to other ships and maritime authorities. Turning those systems off can make a vessel harder to monitor and may increase navigational and collision risks in a crowded or dangerous shipping lane. However, Iran has not publicly supplied independently verified evidence establishing the identity or actions of the two vessels.

Reports Point To Three Tanker Incidents On Saturday

The two incidents announced by the IRGC were not the only tanker-related report from Iran on Saturday. The country’s conventional navy separately said another tanker caught fire and was forced to stop after striking a mine in what it described as a prohibited and unsafe area east of the strait. That vessel was also alleged to have switched off its tracking and identification systems.

As a result, Iranian navy statements described three tanker incidents in total on Saturday: two attributed to the IRGC Navy in the southern passage and a separate incident attributed to the regular navy farther east. The authorities did not identify the vessels or provide confirmed casualty figures. Dawn’s report from AFP and Free Malaysia Today also detailed the three reported incidents.

Independent Verification Remains A Key Question

The claims have not been independently established. Reuters reported that it could not immediately verify the Iranian account of the latest mine incidents. The Rudaw report also noted that the United Kingdom Maritime Trade Operations (UKMTO), which monitors maritime security incidents in the region, had not reported the alleged mine explosions at the time of its report, although it had recorded other incidents in the waterway during the week.

There is also a broader dispute over the safety and status of shipping routes through the strait. Iran says vessels must use routes it authorises, while the United States has said it has cleared the main shipping routes of mines. Those competing positions leave commercial operators navigating a highly uncertain security environment, where a route considered acceptable by one side may be treated as restricted by the other.

Why The Strait Of Hormuz Matters To Global Energy Markets

The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. It is a critical route for crude oil, petroleum products and liquefied natural gas moving from major Gulf producers to international markets. Any sustained disruption can force shipping companies to reconsider routes, raise insurance and freight costs, delay deliveries and add volatility to energy prices.

The latest reports arrive amid a wider pattern of attacks, explosions and maritime restrictions since the conflict began. Reuters reported earlier this week that Iran had blamed explosions involving additional tankers on vessels ignoring warnings and entering areas it considers restricted. In some incidents, maritime authorities have described ships being struck by unidentified projectiles rather than confirming Iran’s explanation that mines were responsible.

Shipping Companies Face Rising Risks

For shipowners, the immediate challenge is determining whether a safe and legally acceptable passage is available. Operators must weigh the risk of mines or other attacks against the commercial cost of delaying voyages or seeking alternative routes. Tankers may also face higher war-risk insurance premiums, additional security requirements and closer scrutiny of their tracking systems and voyage plans.

The latest Iranian statements do not establish who owns the tankers, where they were registered or whether their crews were injured. Those details, along with independent confirmation of the reported mine strikes, will be important in assessing the scale and consequences of the incidents.

For now, the reported explosions underline how the struggle over the Strait of Hormuz has become both a military and economic pressure point. With Iran enforcing its own restrictions and the United States maintaining a naval blockade against Iranian ports, the safety of commercial shipping remains closely tied to the wider conflict and the prospects for diplomatic de-escalation.
