Explosion and Fierce Fire

Iran's Islamic Revolutionary Guard Corps (IRGC) announced on Saturday (17/10/2026) that a supertanker carrying more than 2 million barrels of crude oil caught fire after striking a naval mine in the Strait of Hormuz.

According to an IRGC Navy statement carried by Iranian state media (Sepah News), the vessel crossed the strategic waterway through an 'unauthorized route' in violation of Iranian maritime regulations, triggering a 'massive explosion' and a 'fierce fire'. Iran's Fars news agency posted a video appearing to show the vessel ablaze.

The IRGC accused the tanker of deliberately switching off its GPS and radar to deceive Iranian authorities. The exact location and crew status were not disclosed; the circumstances have not been independently verified, according to AFP and Reuters.

Tehran's Warning, Rejected by Washington

The IRGC Navy warned all shipping that the Strait of Hormuz is 'closed' under Iran's sovereign decisions: the consequence of defying its regulations is 'burning in the fire'. The strait normally carries about 25 percent of the world's seaborne oil trade.

Washington firmly rejects the IRGC's control claims. US Central Command (CENTCOM) chief Admiral Brad Cooper said on Friday that US forces and allies are protecting vessels transiting the strait: 'The Strait of Hormuz is controlled by the United States and our regional partners, not Iran.'

Backdrop: The Iran-Israel-US War

The incident comes amid the US-Israeli war against Iran, which is said to have begun in late February. Mining and attacks on shipping in the strait have kept rising, sharply cutting the number of vessels transiting compared with pre-conflict levels.
