The UK Maritime Trade Operations organization said a vessel in the waters of Oman caught fire.

Based on the agency’s alert, reports of the incident were received on Sunday night by military authorities, and the cause of the fire has not yet been confirmed. The agency advised ships to transit with caution and report any suspicious activity.

The location of the incident was announced as the northernmost point of the Musandam Peninsula in Oman, at the mouth of the Strait of Hormuz.

The Islamic Revolutionary Guard Corps previously, in a statement, claimed that late last night two oil tankers that intended to enter the southern route of the Strait of Hormuz had exploded.

The Islamic Revolutionary Guard Corps claimed that late last night two oil tankers that intended to enter the southern route of the Strait of Hormuz exploded and were prevented from continuing their journey.

Based on the IRGC public relations statement, the two oil tankers were entering that route “by provocation and coercion” from the U.S. Army. The statement did not mention the names of the ships, their nationality, or the status of the crew.

In the same statement, the IRGC said that as long as the U.S. attacks in the region continue, this route would not be safe for even “a drop of oil and gas,” and the U.S. Army should be prepared for “punitive operations.”
