LONDON, England (CNN) -- All passengers and crew aboard a ship touring the Antarctic were safe Friday after the vessel apparently hit an iceberg and started sinking, officials said. No injuries were reported.

The Norwegian cruise ship MS Nord Norge took the stranded passengers and crew on board, a spokesman for Gap Adventures, which owns the sinking vessel, said.
Passenger ship Explorer reported problems near the South Shetland Islands, south of Argentina. The area is in a sector of Antarctica claimed by the United Kingdom.
Nationalities on board include 24 Britons, 17 Dutch, 14 Americans, 12 Canadian and 10 Australians, Gap Adventures said.
Other nationalities include Argentineans, Belgians, Chinese, Danes, French, Irish, Japanese, Swiss, Colombian, Swedes and Germans.
"We believed it has been hulled, it has a hole the size of a fist and some cracking in the hull of the ship, it's taking water and it's listing about 21 degrees," he said.
