Iran’s Revolutionary Guard says two tankers caught fire after striking mines in Strait of Hormuz

Situation Overview

On 20 October 2026, Iran’s Islamic Revolutionary Guard Corps (IRGC) said two tankers caught fire and were detained after an explosion of naval mines in the Strait of Hormuz, which it said were laid in response to an “illegal attempt to pass” through the southern strait. The IRGC said the tankers were “infractors” and reiterated that transiting a mined route is illegal, warning that such actions would lead to the destruction of the tankers’ assets. The IRGC also linked the incident to broader hostility, stating that if the United States persists, oil companies would face a higher “price.” Iranian authorities also claimed that other tankers had struck mines in the previous week, bringing the total to eight vessels colliding with mines in the last week, according to the report.
