Iranian military forces claim that four oil tankers struck naval mines and caught fire while attempting to navigate the Strait of Hormuz, escalating concerns over maritime security and the safety of global energy shipments.
Iran’s armed forces reported Thursday, October 29, that four oil tankers caught fire after allegedly striking naval mines while attempting to navigate the strategically important Strait of Hormuz.
According to statements carried by Iranian state media, the Islamic Revolutionary Guard Corps (IRGC) Navy initially reported that three oil tankers exploded and caught fire within a 24-hour period while attempting to pass through what Tehran described as an unauthorized southern shipping route.
The IRGC alleged that the vessels had switched off their radar and navigation systems and ignored warnings from Iranian naval forces. It said the ships were subsequently disabled and abandoned along the southern shores of the strait.
Later Thursday, Iran’s army reported a fourth incident involving another tanker east of the Strait of Hormuz. The vessel was reportedly damaged and caught fire after striking naval mines while operating in an area designated by Iran as restricted and dangerous.
Iranian authorities did not immediately identify the vessels, their national flags, or the extent of the damage. Details about possible injuries or casualties also remained unclear.
Dispute Over Safe Shipping Routes
The incidents have intensified an ongoing dispute between Tehran and Washington over which shipping routes commercial vessels can safely use to navigate the Strait of Hormuz.
Iran considers the southern corridor, near the Omani coast, an unauthorized route and maintains that vessels must follow shipping routes approved by its authorities.
The United States, meanwhile, has encouraged commercial shipping operators to use the southern passage. US Central Command (CENTCOM) previously maintained that mines had been cleared from primary transit routes through the waterway.
Hossein Mohebi, an IRGC spokesperson, challenged Washington’s assertions, demanding independent evidence to support its claims that the shipping lanes had been cleared of naval mines.
The United Kingdom Maritime Trade Operations (UKMTO) also reported separate maritime security incidents in the area. These included a vessel that caught fire and sank, as well as a tanker struck by an unidentified projectile while completing an outbound transit of the strait.
The British maritime agency’s reports did not independently establish that the vessels had struck mines.
Strategic Importance of the Strait of Hormuz
The Strait of Hormuz is one of the world’s most critical maritime energy corridors, connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea.
Approximately one-fifth of global oil consumption normally passes through the waterway, making disruptions particularly significant for international energy markets and shipping operations.
Since the outbreak of the war on February 28, Iran has severely restricted maritime traffic through the strait. The United States has also imposed a blockade on Iranian ports and supported efforts to facilitate commercial shipping through the region.
The latest reported tanker incidents raise further questions about the safety of commercial vessels and the effectiveness of efforts to restore normal maritime traffic.
As of October 30, independent confirmation of Iran’s claim that all four tankers caught fire after striking naval mines remained unavailable.
