The Revolutionary Guards say two oil tankers caught fire after hitting a mine in the Strait of Hormuz.
The IRGC's navy says two oil tankers caught fire after hitting naval mines in the Strait of Hormuz and exploding.
The statement of the Revolutionary Guards reads: "During the last few hours, two oil tankers in the unauthorized southern passage of the Strait of Hormuz suffered a massive explosion after hitting a naval mine."
The Revolutionary Guards say that these tankers intended to "secretly" pass through the Strait of Hormuz by turning off their identification and location systems.
The BBC has yet to independently confirm the report.
Meanwhile, the British Maritime Operations Center announced on Sunday the report by Indian shipping authorities of a ground attack on an oil tanker in the Strait of Hormuz area.
According to this report, the tanker was the target of a ground attack while passing through the Persian Gulf to the east, before entering the Strait of Hormuz.
Both Iran and the US claim to control the Strait of Hormuz. The Iranian authorities constantly warn that the only safe route through the Strait of Hormuz is the route they have determined.
