A MAJOR rescue operation is under way after a cruise liner began sinking in the Antarctic Ocean.

All 100 passengers and most of the crew have been evacuated off the stricken cruise ship and are awaiting rescue from life rafts.

The MV Explorer is thought to have got into trouble near the South Shetland Islands, south of Argentina, early today after it hit something “significant”.

All but two of the crew have been removed from the vessel and the liner is understood to be listing heavily.

The rescue effort is being coordinated in the US but experts at Falmouth Coastguard in Cornwall are assisting.

Passengers on the liner were on a trip around the Antarctic Peninsula.
