Media reported earlier in the day that a group of Iranians boarded the vessel. In the alleged recording of communications between Asphalt Princess and the UAE coastguard, a crew member said that there were five or six Iranians on board, according to the London-based Argus Media.
"Armed Iranians stormed the vessel ... and tried to take it back to Iran but the crew scuppered the engines, so that is why it was shown bobbing in the water. Then US and Omani warships turned up and the Iranians got into some boats and went off," the source told The Times, adding that the crew were safe.
The Iranian embassy in the United Kingdom has said that Iran had no confirmation of any new incidents in the Gulf of Oman.
Less than a week before the Asphalt Princess incident, an Israel-managed oil tanker was subjected to a drone attack off Oman, which resulted in the death of two security guards. Israel, the United Kingdom and the United States all levelled charges against Tehran.
Iran dismissed allegations of its involvement in the incidents, saying that "no shred" of evidence has been presented.
