Iran's IRGC strikes tanker in Strait of Hormuz and threatens wider maritime attacks

Iran's Revolutionary Guard said on Friday that it set an oil tanker ablaze in the Strait of Hormuz and warned that future action against vessels it considers to be violating rules would not be limited to the narrow waterway. The force said it targeted the engine room and propulsion system of the MV Sun Shine, which it identified as belonging to Natwit, after the ship tried to use what it described as an unauthorised route through the southern part of the strait. The attack caused a fire on board, according to the statement.

The Guard also said it would pursue and punish any ship using routes it deems unauthorised anywhere in the wider region, and said companies it accuses of co-operating with the United States would be sanctioned and their vessels targeted. In the same statement, it blamed the US military for the incidents and accused Washington of interfering in shipping and insurance decisions. Separately, Tehran's Friday prayer leader said the strait would remain closed until Iran's conditions were fully met, adding that the country's military readiness had improved and its strategy had shifted from defence to offence.

Maritime security agencies reported two further strikes on commercial ships in the Persian Gulf on the same day, adding to concern over traffic through one of the world's most sensitive shipping corridors. US Central Command said it had cleared the strait's main shipping lanes, removed naval mines from principal transit routes and declared them open to vessels not in violation of US maritime sanctions against Iran. The competing claims underline the uncertainty facing ship operators, insurers and regional authorities as they assess whether the latest incidents will affect traffic through the waterway.

The Strait of Hormuz is a strategic chokepoint for global energy shipments, and any confirmed attack there can quickly affect shipping costs, insurance premiums and market confidence. The latest claims come amid a wider dispute over Iran's control of the strait and its response to foreign military presence in the area. They also follow a period of heightened tension in maritime transport, with repeated warnings from Tehran that it will respond decisively to what it sees as hostile interference.

What remains unclear is the extent of damage to the MV Sun Shine, whether there were any casualties, and who was behind the additional strikes reported in the Persian Gulf. It is also not yet clear how shipping companies will adjust routes or whether the latest threats will lead to further disruption beyond the strait. The next developments to watch are any confirmation from the vessel's owner, maritime authorities or regional militaries, and whether the situation prompts a broader escalation at sea.

Iran's Revolutionary Guards said they struck an LPG carrier attempting to pass through the Strait of Hormuz by what they described as an illegal route. In a statement carried by state media, the Guards said the vessel, named NV Sunshine, was owned by NatWit and was hit a few hours earlier south of the strait. The claim adds a new maritime security flashpoint to an already tense dispute over access to one of the world's most important shipping lanes.

The statement said Iranian forces had taken control of the administration of the strait, reinforcing earlier warnings from Tehran that it was prepared to tighten its grip on the waterway. The incident was linked by Iranian officials to wider conflict and diplomacy in the region, where negotiations have been deadlocked for months. President Masoud Pezeshkian said earlier on Friday that peace talks would only work without pressure and threats, and that negotiations conducted under force were not genuine talks.

The Strait of Hormuz is a narrow passage through which a large share of Gulf energy exports normally moves, making it strategically significant for oil and gas markets as well as for commercial shipping. Any confirmed strike on a tanker there raises the risk of disruption, higher insurance costs and further caution among ship operators. The latest claim also comes after recent reports of attacks on ships in the same area and renewed concern that maritime access is becoming part of the wider confrontation.

The broader backdrop is a seven-month conflict that has already seen military action, failed indirect talks and repeated warnings over Iran's nuclear programme. The supporting material says the United States and Iran agreed a memorandum of understanding in June, but that later attacks on ships in the strait prompted a resumption of US military operations. Recent indirect discussions on the sidelines of the UN General Assembly did not produce a breakthrough, leaving the diplomatic track stalled while tensions at sea continued.

Iranian officials have also tied the dispute to sanctions, regional trade and energy security, arguing that pressure on Tehran affects the wider economy. Pezeshkian said sanctions would harm regional trade, connectivity, energy and order, while also accusing the US of using negotiations as cover for attack. Those remarks underline why the strait matters beyond the immediate incident: it is both a shipping corridor and a pressure point in the wider standoff.

What remains unclear is whether the NV Sunshine was damaged, whether there were any casualties, and how much traffic is still moving through the strait. It is also not clear how other states or shipping operators will respond to the claim, or whether the latest strike will affect the already fragile diplomatic channel. The next developments to watch are any confirmation from the vessel's owner or maritime authorities, any change in shipping patterns, and whether the incident prompts a new round of pressure or retaliation.
