Iran on Friday denied it owned the cargo on one of its flagged tankers that was seized following a suspected illicit ship-to-ship (STS) transfer off the coast of Indonesia.

The 300,600-dwt Arman 114 (built 1997), carrying 2m barrels of crude, was held after it was spotted in the North Natuna Sea carrying out an STS operation without the authorities having been notified, according to Indonesia’s maritime security agency Bakamla.
