The navy of Iran's Islamic Revolutionary Guard Corps (IRGC) announced on Friday, 9 October that its forces had struck a 'giant' liquefied petroleum gas (LPG) carrier, identified as NV Sunshine, as it attempted to cross the Strait of Hormuz through what the IRGC described as an 'illegal' southern route. The strike caused a fire in the vessel's engine room and propulsion system, according to a statement published on the IRGC's official outlet Sepah News.

Details of the Strike

The IRGC Navy stated that the NV Sunshine, a large LPG-carrying vessel, was targeted after it allegedly attempted to transit the strait via an unauthorised corridor. Following the strike, the ship reportedly caught fire in its engine room and propulsion system, though the statement did not provide details on casualties or the extent of structural damage.

Notably, this incident marks a fresh escalation in maritime tensions around one of the world's most strategically critical chokepoints, through which roughly 20% of global oil and energy shipments transit annually.

IRGC's Warning to Shipping Companies

The IRGC issued a stark warning to international shipping and insurance companies, threatening sanctions and 'punitive measures' against any vessel belonging to companies that, in its words, allow themselves to be 'deceived by the United States.' The statement held the US military directly responsible for the incident, alleging that Washington orchestrates such escalations through interventions, manipulation of shipping and insurance firms, and the payment of what it characterised as 'massive bribes.'

The IRGC further declared that future enforcement against vessels using unauthorised routes will not be confined to the Strait of Hormuz — any offending ship could be 'pursued, and definitely punished' anywhere in the region. The corps also asserted it maintains 'full control' of the strait and vowed to prevent what it termed 'aggressive' foreign military presence in the area.

Iran-US Diplomacy Continues in Parallel

Even as the maritime confrontation intensified, Iranian President Masoud Pezeshkian signalled Tehran's continued willingness to engage diplomatically with Washington. Speaking on Thursday at a meeting with Russian President Vladimir Putin in Turkmenbashi, Turkmenistan, Pezeshkian acknowledged that the United States had attacked Iran twice during previous rounds of talks, but said Tehran would not walk away from negotiations.

According to a statement issued by his office, Pezeshkian said: 'We are negotiating. However, whenever we engage in dialogue with the United States, they attack again. Nevertheless, we will not abandon the negotiating table and dialogue.'

He added that Iran had submitted proposals to which the US had responded with counter-proposals, and that Tehran had revised its position. He indicated the two sides plan to 'sit down and conclude them through the existing mediators' once the revisions are finalised.

Regional and Global Implications

The Strait of Hormuz remains a pressure point of acute strategic consequence — any sustained disruption would rattle global energy markets and shipping insurance costs. This incident follows a pattern of IRGC vessel seizures and confrontations in the strait, which have intensified amid broader Iran-US tensions over Tehran's nuclear programme and regional influence. The latest strike signals that the IRGC is prepared to extend its enforcement posture well beyond the strait itself, raising the risk calculus for commercial shipping across the entire Persian Gulf and Arabian Sea corridor.

How international maritime bodies, the US Navy, and affected shipping firms respond in the coming days will determine whether this remains an isolated confrontation or the opening of a new phase of maritime pressure.
