An investigation is under way after three people were killed in a fire on the luxury cruise ship Oceania Insignia in St Lucia.
The cruise line has confirmed that the victims were a crew member and two contractors.
"We extend our deepest condolences to their families during this very difficult time," it said in a statement.
According to local newswires, the victims suffered severe burns.
St Lucia News Online said a 42-year-old male is also under observation at hospital for mild respiratory depression caused by smoke inhalation.
According to the authorities, the fire started in one of the ship’s four engines and fire crews were called at around 9.25am on Thursday morning.
The 656 passengers were evacuated safely and the rest of the cruise was cancelled.
The Insignia was on a 10-day trip and was due to arrive in Miami on December 17.
The cruise line said all passengers would be fully refunded and charter flights would fly them to Miami, where they would be accommodated before being flown back to their departure airports.
