Iran says four oil tankers caught fire after striking naval mines in the Strait of Hormuz, in a claim that directly disputes the United States military’s assertion that key routes through the strategic waterway had been cleared.
Iran’s Islamic Revolutionary Guards Corps (IRGC) said three “violating oil tankers” exploded and caught fire over the previous 24 hours after hitting mines while attempting to pass through what it called the “unauthorised southern route” of the strait. Iran’s army later reported that a fourth tanker had caught fire east of the strait after hitting mines while operating in what Tehran described as a restricted and dangerous area.
The claims were reported on Thursday, a day after the US military said it had cleared key routes through the waterway. The IRGC said the first three vessels had switched off all their radar and navigation systems and had disregarded warnings from its navy.
What Iran is claiming — and what is independently confirmed
The distinction matters. The account of three tankers hitting mines on the southern route comes from the IRGC alone. The Iranian statement did not specify when the incidents occurred or which flags the tankers were flying, and no casualties have been reported by the outlets carrying the claim.
Separately, the British maritime agency UKMTO said it had received a report of a vessel on fire about 25 nautical miles (46 kilometres) northeast of Khasab, Oman, in the strait. That report confirms a vessel fire; it does not confirm the mine cause, the tanker count, or whether the vessel is one of the four Iran described. This article does not merge the two reports into a single incident.
The IRGC used the statement to challenge the US position directly. Its spokesman, Hossein Mohebi, wrote on X: “Prove your Hormuz mine-clearing claim with independent evidence, not statements!” The Guards’ statement added that “the unauthorised route through the Strait of Hormuz is mined, and that vessel owners and crews are responsible for transiting these routes.”
Why the strait matters
The Strait of Hormuz is one of the world’s most important energy chokepoints, normally carrying about one-fifth of global oil consumption. Iran has severely restricted traffic through the waterway since the war began on 28 February, and it considers ships using the southern corridor near the Omani coast unauthorised.
That makes the competing claims consequential for shipping and energy markets: if the southern route is mined, as Iran says, vessels and insurers face a different risk picture than the one presented by the US military’s clearance claim. Neither claim has been independently verified in full, and the gap between them is itself the story.
A wider pattern of Hormuz incidents
The mine-fire claim is the latest in a run of Hormuz shipping incidents reported in recent days, including Iran’s earlier statement that two tankers were stopped south of the strait after ignoring radio warnings. Each incident has arrived with partial information — an Iranian claim, a maritime-agency report, or both — and with key details such as vessel identities and flags still unconfirmed.

What remains unknown
Several questions are still open: the identities and flags of the four tankers, the exact times of the incidents, whether any cargo was lost, whether anyone was hurt, who laid any mines, and whether the southern route remains navigable. Until maritime agencies or vessel operators confirm those details, the mine strikes should be read as an Iranian claim that is partly echoed — but not confirmed — by the UKMTO fire report.
What happens next will depend on verification: further UKMTO advisories, statements from vessel owners or flag states, and any response from US Central Command to the IRGC’s challenge.

FAQ
Did four tankers definitely hit mines in the Strait of Hormuz? Iran says so; UKMTO has confirmed a vessel on fire in the strait but not the mine cause or the count. The mine strikes remain an Iranian claim pending independent verification.
Why does Iran call the route unauthorised? Iran considers ships using the southern corridor near the Omani coast unauthorised, while the US military says it cleared key routes through the waterway. The two positions directly conflict.
Were there casualties? None have been reported by the outlets carrying the claim.
