A crew member takes pictures with a mobile phone on Iranian oil tanker Adrian Darya 1, previously named Grace 1, as it sits anchored after the Supreme Court of the British territory lifted its detention order, in the Strait of Gibraltar, Spain, August 18, 2019.
"The tanker has gone to its destination, the oil has been sold", spokesman Abbas Mousavi told the television station without disclosing whether the crude oil had been delivered.
Early on September 7, USA national-security adviser John Bolton tweeted a satellite image that appeared to show the tanker near the Syrian port city of Tartus.
"We had already announced that we would sell our oil in any way and that acts of sabotage would not affect our plans", he added.
Maritime tracking service TankerTrackers said that as of Sunday night the Adrian Darya was off the coast of Syria's Tartus but had not unloaded the oil.
According to Spain's Foreign Ministry, the United Kingdom had seized the vessel at the request of the USA, which has been trying to trouble Iran's worldwide oil vessels as part of its campaign of economic pressure against the Islamic Republic.
The US vowed on Sunday to impose sanctions on any buyer of the oil.
Also Sunday, a USA official said the United States would continue to impose sanctions on whoever purchased Iran's oil or conducted business with Iran's Revolutionary Guard, and that no oil waivers would be reissued.
The Stena Impero was going through the final legal processes and would be released "soon", spokesman Abbas Mousavi said. To make sure the captain did not mistake the email for a scam, it included an official state department phone number.
"We can't talk, but Iran's not getting any sanctions relief until it stops lying and spreading terror".
A Gibraltar court ordered its release on August 15 despite an 11th-hour U.S. legal bid to keep it in detention. Daily exports could be as little as a couple of hundred thousand barrels, or exceed the 1 million a day shipped during previous sanctions under Trump's predecessor Barack Obama.
Iran has also the UK-Flagged Stena Impero oil tanker in detention for violating global maritime law in the Strait of Hormuz in June.
The official said, "We have no problem with the crew and captain of the ship".
The vessel was detained for six weeks and eventually released following objections from the United States when Gibraltar said it trusted it would not head for any countries under European Union sanctions.
