Iran’s IRGC says mines hit four oil tankers in the Strait of Hormuz

Situation Overview

On 4 November 2026, Iran’s Islamic Revolutionary Guard Corps (IRGC) said in a statement that mines in the Strait of Hormuz caused four oil tankers to be destroyed in the southern part of the strait and that they were still burning. The IRGC also said two other vessels were stopped and claimed the downing of an American MQ-9 drone. In a separate statement, the IRGC described the tankers as having intended to transit through a “forbidden route” south of the Strait of Hormuz. The claims follow recent Iranian media reports citing IRGC and Iranian army statements about incidents involving ships transiting the strait and mines allegedly laid in the waterway. The next concrete items to watch are further IRGC updates on the status of the stopped vessels and any official responses from the United States regarding the claimed MQ-9 downing.

Geopolitical Implications

1. 01

   Claims of mines and drone losses in the Strait of Hormuz heighten perceived risk to shipping amid Iran–US maritime tensions.
