DUBAI - Iran's Islamic Revolutionary Guard Corps (IRGC) have intercepted a Togo-flagged, UAE-managed products tanker carrying 1,500 tons of marine gas oil, British security firm Ambrey said on Monday.

The vessel had loaded marine gas oil off the coast of Iraq and was destined for UAE's Sharjah when it was intercepted on Sunday 61 nautical miles southwest of Iran's port of Bushehr, Ambrey said.

Ambrey added that the incident is unlikely to be politically motivated and is not assessed as a 'war' event.

The interception was likely a counter-smuggling operation by the IRGC, as the vessel's "trading behaviour was consistent with previous IRGC target profile", Ambrey said.

Iran, which has some of the world's cheapest fuel prices due to heavy subsidies and the plunge in the value of its currency, has been fighting rampant fuel smuggling by land to neighbouring countries and by sea to Gulf Arab states.

No further information was provided regarding the fate of the vessel.
