Iran’s Islamic Revolutionary Guard Corps (IRGC) said on Wednesday that four oil tankers were destroyed after striking naval mines near the Strait of Hormuz, in a claim that could not be independently verified and that named none of the vessels involved. The claim, carried by Iranian state media and reported by Reuters, is the latest threat to Strait of Hormuz tankers and to commercial shipping through one of the world’s most important energy routes, where attacks on tankers have intensified during the war between Iran and the United States.
According to the IRGC statement, the four tankers were trying to use a route south of the Strait of Hormuz that Iran has declared prohibited for navigation when they hit mines. The corps said the tankers were still ablaze and that two other vessels had been seized for violating shipping restrictions. No further details were given.

What Iran claimed about the Strait of Hormuz tankers
The IRGC statement, reported on Wednesday 4 November, said the four tankers struck naval mines while attempting to cross a passage south of the Strait of Hormuz that Iranian authorities have declared prohibited. The corps said the vessels caught fire and remained ablaze, and that two additional vessels had been detained for violating shipping restrictions.
Iranian state media carried the statement, and the claim was also reported by Anadolu Agency. In the same statement, the IRGC further claimed that its air defences had shot down a US-made MQ-9 Reaper drone over the Strait of Hormuz in the early hours of Wednesday. That claim, too, was made without supporting evidence in the reports.
What remains unverified
The claims could not be independently verified, and key details remain missing. The IRGC statement gave no names, flags, owners, ports of departure or destinations for the four tankers, and no information about their crews or the extent of any damage beyond the claim that the vessels were on fire.
No advisory from the United Kingdom Maritime Trade Operations (UKMTO) confirming four mine strikes or fires had been reported, and neither US Central Command nor any flag state, insurer or shipping tracker had confirmed the loss of vessels to mines. Until such confirmation appears, the destruction of the four tankers should be treated as a claim by the Iranian military, not as an established fact.
Separate tanker attack confirmed off Oman
Separately, UKMTO confirmed on 3 November that a tanker was struck by two unidentified projectiles in its engine room at around 1900 UTC, about 14 nautical miles north-east of Lima, Oman. The vessel’s company security officer reported the strike, and UKMTO said there were no reported casualties or environmental impacts at the time of its warning.
Shipping reports identified the vessel as the Barbados-flagged very large crude carrier Grit, which had reportedly been placed on an Iranian blacklist earlier in the week. The identity of those responsible for that attack has not been independently established, and projectiles are not mines — the Oman incident is distinct from the mine-strike claim made a day later.
The confirmed Oman strike followed a fatal attack on an Indian-crewed vessel near Oman on 2 November, in which one Indian sailor was killed and 13 others were rescued. India has since called for stronger international action to protect civilian vessels and seafarers in conflict-affected waters.
Why the Strait of Hormuz matters
The Strait of Hormuz, the narrow waterway between Iran and Oman at the mouth of the Gulf, is one of the world’s most important energy shipping routes, and shipping through it has been severely disrupted since the war between the United States and Israel on one side and Iran on the other began on 28 February. Tehran has declared the strait closed, while the United States has imposed a naval blockade on Iran.
Maritime security firm DIAPLOUS warned in a 3 November assessment of an elevated risk of renewed US–Iran military escalation during 3–6 November, citing recent military developments, continued attacks against merchant shipping and unresolved diplomatic tensions. It advised operators to reassess planned transits and monitor UKMTO advisories, while noting that its assessment was a risk outlook rather than confirmation that further hostilities would occur.

What happens next
Attention now turns to whether any maritime authority, flag state or shipping company confirms the IRGC’s account, names a vessel, or reports a crew casualty or an oil spill. Without that confirmation, the claim stands as an assertion in an information war running alongside a real shooting war — one in which merchant crews, not only warships, are paying the price. Watan News will update this story as verified information emerges.
