(CNN) Iran has released a short video of what it says is the crew of the Stena Impero, the British-flagged tanker that was seized by Iranian forces in the Strait of Hormuz on Friday.

The footage was posted Monday on the website of Iran's semi-official Fars news agency. In what appear to be staged shots, it shows several crew members in various locations around the tanker.

The crew can be seen talking in a meeting room, operating the ship's systems and cooking in the vessel's kitchen. A spokesperson for Stena Bulk, the company that operates the tanker, told CNN that they could not verify the authenticity or the source of the video.
