Iran Reports More Hormuz Mine Strikes and Warns US Warships

The latest escalation began with Iranian claims that naval mines had stopped tankers crossing the Strait of Hormuz. On October 20, The Hindu reported that Iranian forces had repeatedly targeted ships using a southern route close to the Omani coast.

The initial accounts differed on the number involved. Notícias ao Minuto reported an Iranian claim concerning two tankers, while Middle East Eye reported an IRGC claim that three had been halted. The supplied reports do not establish whether these accounts described the same incidents.

The threat was also becoming more destructive. Bloomberg reported on October 20 that Iranian attacks were hitting more ships and causing more severe damage than earlier in the conflict, putting regional energy flows at fresh risk.

On October 21, the confrontation extended beyond tankers. A senior IRGC official warned that undersea internet cables in the Strait of Hormuz would be targeted if Iran's infrastructure was attacked, according to Mehr News (English).

The same day, Amwaj Media reported that the US said it had imposed a naval blockade targeting vessels travelling to and from Iran's southern ports. The move came during a tenuous truce and prompted Iranian threats of retaliation.

On October 22, Iran said seven oil tankers had caught fire or been damaged overnight after attacks or mine strikes, according to Associated Press. A more detailed Iranian account, carried by IRNA English, said four ships were hit and caught fire while transferring oil in the northern Persian Gulf, with three other vessels suffering incidents.

Those claims were not independently confirmed, according to Global News. Al Jazeera reported that the US dismissed the IRGC's claims as an attempt to increase oil prices ahead of US elections.

On October 23, Middle East Eye reported a further IRGC claim that two supertankers had struck mines while attempting to use an unauthorised route south of the strait. An account from Mehr News (English), dated October 24 in its summary, said the ships were disabled and their crews abandoned them.

The latest tanker claims remain unverified, according to Mint. They add to Iran's assertions of control over passage through the strait, but the available coverage does not independently establish the full number of damaged vessels or the extent of their damage.

On October 24, Major General Ali Abdollahi, Chief of the General Staff of Iran's Armed Forces, said Iran would never allow US warships to re-enter the Persian Gulf, according to IRNA English. This was a warning, not a reported new encounter with US vessels.

The attacks have not yet translated into a clear collapse in regional oil shipments. Bloomberg reported on October 21 that Middle Eastern oil flows were near prewar levels despite more frequent and damaging attacks. Middle East Eye reported that ship-to-ship transfers and transits through the Red Sea were helping sustain exports.

Independent confirmation of the latest mine strikes remains a key gap, including the condition of the two supertankers and their crews. Whether oil shipments continue to hold up will also help show how much practical disruption the attacks are causing.

The other immediate risk is a wider military response. Iran has tied its threat against undersea cables to attacks on its infrastructure, while its latest warning seeks to bar US warships from the Gulf. The supplied coverage does not establish whether either threat will be carried out.
