Iran's Revolutionary Guards say two oil tankers hit mines in Strait of Hormuz

Iran's Islamic Revolutionary Guard Corps (IRGC) Navy said on Saturday that two oil tankers had caught fire after hitting naval mines while crossing the Strait of Hormuz. Iran's official news agency IRNA reported the statement. Al Jazeera and Reuters both carried it.

The statement is confirmed. The incident itself is not. Both outlets trace the account to the same source, the IRGC via IRNA. The reports reviewed by Vocemundi include no confirmation from ship operators, flag states, UKMTO, the International Maritime Organization (IMO) or other maritime monitors.

The reports do not include the tankers' names, flags, owners or operators, or where their cargo came from. According to Al Jazeera, this information was not immediately available. The reports also do not describe casualties, rescue efforts, damage or any oil spill. They do not give the precise location or time, and they do not say who laid the mines.

Context

According to Al Jazeera, attacks around the waterway have surged over the past two weeks. Al Jazeera cited security firm Vanguard, the IMO and UKMTO as reporting that six vessels were attacked in or near the strait on the previous Sunday. That was the most in a single day since the war began. Maritime monitors also reported two tankers struck in Gulf waters off Saudi Arabia on Friday, Al Jazeera said.

Kpler data cited by Al Jazeera show nearly 20.8 million barrels of oil passed through the strait on 8 October, but only 2.9 million on 11 October. Before the war, about one-fifth of global oil consumption used the route, according to Al Jazeera.

Al Jazeera reported that Iran took control of the strait after the US-Israeli war on the country began in late February. Since then, Tehran has demanded that ships seek its authorisation before transiting. The United States has imposed a naval counter-blockade on Iranian oil exports, and tougher sanctions on Iran were imposed last month, Al Jazeera said. It also reported that the disruption has pushed up global energy prices and inflation.

What is unclear

The IRGC said both tankers caught fire. It also said one tanker attempted the crossing while the second was left immobilised. The reports do not explain how these accounts fit together. They also do not establish whether these tankers are linked to other recent incidents: the two tankers Iran's army said caught fire on Thursday and Friday in its "prohibited zone" in the Gulf of Oman, or the two tankers struck off Saudi Arabia on Friday.

What each side says

• IRGC (via IRNA): Each tanker carried about two million barrels of crude oil. The first strike caused an explosion and a "fierce fire"; the second tanker was engulfed "in a massive blaze". The IRGC said one tanker tried to cross "with US support".
• IRNA: The vessels had switched off their positioning and radar systems and tried to use a route not authorised by Iran.
• Rear Admiral Ali Azmaei, IRGC naval commander: Earlier this week, he warned that any vessel deactivating its navigation systems would be considered "hostile".
• Iran: It says it is stepping up strikes in response to the US blockade of its ports and last month's tougher sanctions.
• United States: The reports do not include a US response to the IRGC claim. In an interview with Newsmax on Thursday, President Donald Trump ruled out using a nuclear weapon against Iran, saying "I wouldn't use nuclear". He said he was not considering ground troops and believes a deal to end the war will be reached after the 3 November US midterm elections.

Analysis

If independently confirmed, mine strikes would mark a further risk for shipping in a waterway where traffic has already fallen sharply, according to Kpler data cited by Al Jazeera. For now, the account rests on a single origin: a statement by a party to the conflict. Confirmation or denial from shipowners, flag states or maritime monitors would clarify what happened. Several scenarios remain open. The claim could be verified, contested or left unresolved. Separately, Iran's stated link between its strikes and the US blockade, and President Trump's stated expectation of a deal after the US midterms, suggest pressure and diplomacy may continue in parallel. Neither outcome is certain.
