Iran's state broadcaster has aired a video showing for the first time the 23-member crew of the British-flagged ship seized by Iran.
In the video aired on Monday, the Stena Impero crew is seen dressed in red uniforms and seated around a table onboard the vessel as an unidentified Iranian man is heard thanking them for their cooperation. A cameraman is heard telling them not to look at the camera.
It wasn't clear if the crew was under duress to take part in the filming.
Other shots show a man checking on the ship, the crew sharing a laugh and talking next to a coffee machine inside the ship. The crew's chefs are seen preparing food. Another video, also released by Iran's state broadcaster, shows Iran's flag hoisted on the ship's bridge.
The ship was seized Friday in the Strait of Hormuz. None of the crew are British nationals but are mostly Indian and also Filipino, Russian and Latvian nationals.
Meanwhile in one of her last days as British Prime Minister, Theresa May has chaired an emergency security session to discuss how to respond to Iran's actions.
The meeting of security ministers and officials on Monday discussed how to secure shipping in the sensitive region, which is vital to the world's oil supply.
Britain is considering a number of options to raise the pressure on Iran but officials say military operations are not being considered at the moment.
