Iran has claimed that its fast-attack speedboats were deployed to chase down a Royal Navy destroyer in the Persian Gulf this week. In video footage posted by the Iranian Revolutionary Guard (IRGC), the Type-45 destroyer is allegedly being pursued by Iranian gunboats. The video reveals a warship sailing in the distance while a group of smaller boats armed with machine guns follow behind at some distance.
However, viewers on social media quickly disputed the claim that the ship identified in the video was not HMS Duncan.
It is now believed that the IRGC mistook a UAE Baynunah-class ship for a British navy ship.
Conflict News Worldwide, which tweeted the video, posted a correction of the clip.
CNW tweeted: "IRGC obviously have an information failure as they thought it was a British vessel, looks like they chased a random warship instead."

Another intelligence account that posted the video tweeted: "Claims of harassing a British warship are nonsense. This is not HMS Duncan or Montrose.
"All it shows is a boat struggling to keep up with a warship, almost certainly a UAE Baynunah class corvette."
HMS Duncan has been in the Strait of Hormuz for the past few weeks amid ongoing tensions between Britain and Iran.
The HMS Duncan's deployment to the Strait was accelerated amid a growing hostility between the two powers.
Royal Navy vessels are guarding all British shipping sailing through the vital waterway after the illegal seizure of the tanker Stena Impero by Iran last month.
HMS Duncan is in the Persian Gulf alonside HMS Montrose, whose captain Commander William King confirmed they have had at least 85 run-ins with Iran.
Speaking on BBC Radio 4, Commander King said: “I've had 85 interactions with Iranian forces over the last 27 days - so that gives you some idea of the intensity.

“The Iranians seem to be keen to test our resolve, test our reactions, most of that time.
"We're on guard. We're ready to react. I’ve got 215 in my team who are highly trained and relishing the professional opportunities of being slightly under threat represents.”
It comes after claims that an Iranian bomb boat was found in the path of the HMS Duncan as it arrived in the Gulf in July.
It was spotted by Saudi forces near to the destroyer's route after Iran said Britain was "playing a dangerous game" by sending the destroyer.
