IRGC Reports Tanker Mine Strikes in Strait of Hormuz

The Islamic Revolutionary Guard Corps (IRGC) Navy reported on October 17, 2026, that two oil tankers carrying approximately 2 million barrels of crude oil caught fire after striking naval mines in the Strait of Hormuz. The IRGC claimed the vessels attempted to transit the strait illegally through deception, disabling their radar and positioning systems with support from the U.S. military. One vessel was left immobilized. These reports follow a surge in maritime attacks that Iran attributes to its response to a United States blockade of Iranian ports and increased sanctions.

Concurrent attacks occurred northeast of Al Jubayl, Saudi Arabia, where two tankers were struck by projectiles on October 16. One vessel was hit by a rocket-propelled grenade from a small boat, while the other was struck by an unidentified projectile; crews were evacuated without casualties. Additionally, the Singapore-flagged GFS Pride and Antigua and Barbuda-flagged Cape Dao sank near the Strait of Hormuz following projectile attacks on October 13 and September 23, respectively.

These incidents have driven Brent crude prices above $110 per barrel. The International Energy Agency warned that a global diesel squeeze will persist through the first half of next year. Iranian officials stated that Tehran is employing new tactics in the waterway to maintain high oil prices and influence U.S. midterm elections. A United Nations official warned that failure to reach a U.S.-Iran agreement on fertilizer transport could trigger a food security crisis in Asia and Africa.
