Iran’s IRGC Mines Ignite Tankers Amid Escalating Strait of Hormuz Crisis

Core Incident: Mines Strike Tankers
On October 17 the Islamic Revolutionary Guard Corps (IRGC) navy announced that two oil tankers caught fire after striking naval mines it had laid in the southern Strait of Hormuz. The IRGC said the vessels were using an “illegal route” and that the explosions set the ships ablaze and halted their progress. State media reported that one tanker carried roughly 2 million barrels of crude oil and that the second was left immobilised after the blast.
Background & Context
The Strait of Hormuz has been a focal point of the conflict that began on February 28 when the United States and Israel launched a war against Iran. Tehran has maintained a shipping corridor inside its territorial waters, imposing tolls that the International Maritime Organization (IMO) and Washington deem inconsistent with international law. The IMO-approved traffic separation scheme, adopted in 1968, remains the only recognized route for trans-it vessels.
Data & Statistics
- UK Maritime Trade Operations (UKMTO) recorded 254 commercial transits in the week to October 14, about 70 % below pre-conflict levels.
- In the seven days to October 16, UKMTO counted 12 vessels attacked, the highest weekly total it has tracked.
- An October 18 advisory maintained a “severe” threat assessment and warned of further attacks.
- IMO Secretary-General Arsenio Domínguez said roughly 6,000 seafarers have been stranded in the strait since the war began.
- Oil flows fell to 2.9 million barrels on October 11, the lowest figure of the month, after earlier averaging 15.5 million barrels a day in the region.
Official Statements & Responses
The IMO warned that sea mines continue to endanger navigation and that verification of cleared routes is hampered by the ongoing conflict. Domínguez emphasized that only the 1968-approved route appears on official charts and that its safety cannot be guaranteed while mines remain.
Iranian Foreign Minister Abbas Araqchi reiterated that Tehran’s seven-day proposal to the United States remains on the table and accused Washington of lacking honesty.
Foreign Ministry spokesperson Esmail Baghaei warned that any U.S. attack on the Iranian-controlled Kuh Kalang would be met with retaliation.
On-the-Ground Reports
UKMTO reported an incident 121 nautical miles east of Duqm, Oman, involving an oil tanker and military forces, with no damage or casualties. A Dutch-flagged tug (IMO 9345506) was struck by two projectiles near the Musandam Peninsula; one crew member suffered minor injuries but the vessel continued its voyage.
Conflicting Reports & Gaps
Sources differ on the total number of vessels hit. Fox News cited 24 ships attacked over roughly two weeks, while UKMTO’s data for October 5-11 recorded 12 attacks, and the Guardian noted that the exact count of ships struck by mines versus shelling remains disputed. No independent verification has been provided for the video of a burning supertanker shown by Fars news agency.
What’s Next
Negotiations continue over Tehran’s seven-day proposal, which Iran says remains on the table pending an “honest” U.S. response. The IMO indicated it will review communications protocols after Iran’s allegation that the U.S. used the VHF Channel 16 distress frequency for intimidation.
