A woman has died and four people have been injured after a "rogue wave" struck the Viking Polaris luxury cruise ship in the Atlantic Ocean during its Antarctic Explorer Cruise.
The Viking Polaris was struck by the wave at 10:40pm on Wednesday as it sailed towards the Argentinian resort town of Ushuaia as part of its Antarctic Explorer cruise.
The cruise operator said the vessel arrived at its destination in Ushuaia the same afternoon without further problems, they added that the ship "sustained limited damage".
A spokesperson for Viking said: "It is with great sadness that we confirm a guest passed away following the incident.
"We have notified the guest's family and shared our deepest sympathies."
According to the Associated Press, the deceased passenger was a 62-year-old American woman.
The woman was struck by broken glass when the wave shattered the cabin's windows.
Medical staff on board the ship treated the four other passengers who suffered injuries during the incident.
The Viking Polaris had only been launched earlier this year and was advertised as a luxury vessel offering the very best facilities with a capacity for 378 passengers and 256 crew members.
Viking confirmed that an investigation has been launched and classed it as a "rogue wave incident".
A rogue wave is usually defined as a wave that is two times the significant wave height of the area.
The significant wave height is the average of the highest one-third of waves - so a rogue wave is a log bigger than the others.
The vessel's next scheduled departure has been cancelled by Viking.
