Footage from a cruise ship left stranded after it started experiencing engine failure shows the dramatic moment passengers were told something was wrong.
Hundreds of passengers have been evacuated from the Viking Sky cruise which ran into difficulties off Norway's western coast on Saturday.
A rescue mission was launched with helicopters and boats sent to remove people from the ship which had set up anchor in Hustadsvika Bay.
By Sunday morning, it was reported that 400 passengers of the 1,300 on board had been evacuated. Officials have confirmed 16 people were injured - three of which had been seriously injured.
Footage from the ship has been released showing the moment the emergency alarm sounded with worried passengers looking on.
Several people are seen glancing around anxiously as the seriousness of the incident becomes clear, and people are told to sit down.
A male crew member is seen telling people: "Please just remain seated."
Another female worker can be heard saying: "Everybody sit. Please stay seated."
At that point an automated message cuts in over the tannoy. Before the video comes to an end, the message says: "This is the general emergency signal."
Derek and Esther Browne from Hampshire were aboard the ship and have been speaking about the "frightening" experience of being airlifted from the vessell.
Mr Browne told BBC Radio 5 Live's Stephen Nolan: "We had a few people on stretchers, several with cuts, two with broken limbs, but fortunately we were alright. We were airlifted onto the helicopter which was quite a frightening experience."

He added: "I'd never been in a helicopter before, there were a lot of high winds, hovering overhead and the winchman came down and we were then collected up and so I shut my eyes as we arrived into the helicopter and there were 15 of us for about a 20-minute ride."
The ship was visiting the Norwegian towns and cities of Narvik, Alta, Tromso, Bodo and Stavanger before its scheduled arrival in Tilbury in Essex on Tuesday.
A spokeswoman for Viking Cruises said: "The ship is proceeding on its own power and a tugboat is on site. The evacuation is proceeding with all necessary caution.
"A small number of non-life threatening injuries have been reported. Guests are being accommodated in local hotels when they arrive back on shore, and Viking will arrange for return flights for all guests."
A spokeswoman for the Foreign Office said: "We are in touch with Norwegian authorities and stand ready to help any British people who require our assistance".
