Hormuz Shipping Threat Remains Severe After Ship Sinkings and Tanker Fire

The latest attacks follow months of Iranian efforts to control passage through the Strait of Hormuz. According to NDTV, the war began in late February with US and Israeli strikes against Tehran. Iran has since claimed control of the strait and regularly targeted ships attempting to transit without its permission.

The pace of attacks has increased sharply. Middle East Eye reported that Iranian missile and drone attacks on shipping in and around the strait reached their highest wartime intensity in the two weeks to October 11.

On October 13, NDTV reported that two ships had been hit by missiles, citing a UK maritime agency. That day, General Ali Ozamaei, Commander of the IRGC Navy, warned that US warships approaching the strait would be sunk, according to Mehr News.

On October 14, the IRGC Navy said a container ship carrying more than 2,500 containers had struck a naval mine, caught fire and sunk south of the strait, IRNA reported. A separate account from Singaporean authorities, reported by the BBC, said the Singapore-flagged GFS Pride sank after being struck by an unknown projectile. All 21 crew members were evacuated. The accounts differ on the weapon involved, so a mine strike should not be treated as established.

Reports of a second ship loss also emerged. Middle East Eye reported on October 14 that the Antigua and Barbuda-flagged Cape Dao had sunk near the strait after a projectile struck it on September 23. That earlier strike date matters: the report does not establish that both ships were attacked during the latest surge.

The attacks coincided with reports of a deliberate change in Iranian strategy. On October 14, The Japan Times cited two senior Iranian officials saying the aim was to keep oil prices high ahead of the US vote. Euronews reported that oil prices rose as fresh attacks fuelled supply concerns.

On October 15, Iran's Army Navy said it had spotted a burning oil tanker attempting to pass through the eastern Strait of Hormuz, according to IRNA. Euronews reported Iran's claim that the unnamed vessel had entered a prohibited zone with its tracking systems disabled. Those reports do not establish what caused the fire.

The UK Maritime Trade Operations centre says the threat to merchant shipping remains "severe" and further attacks are "highly likely", Middle East Eye reported on October 16. That is the latest assessment in the coverage, after the ship losses and reported tanker fire.

Military claims about control remain contested. On October 15, Iran's deputy army coordinator said the strait was closed and transit required coordination, according to Mehr News. US Central Command dismissed Iranian claims of control, Middle East Eye reported. Neither side's statement resolves the immediate safety risk to commercial vessels.

The immediate issue is whether more merchant vessels are struck, given the latest maritime warning. Confirmation of the weapon that sank GFS Pride and the cause of the tanker fire would also help distinguish verified events from Iranian claims.

The geographical reach of further attacks is another concern. NDTV reported on October 14 that Iranian officials described plans to expand operations beyond the strait into the Gulf of Oman and waters farther afield. That is a reported intention, not confirmation that the planned expansion has occurred.
