The Olympic flame has travelled to the North Pole aboard a Russian nuclear-powered icebreaker, according to the organisers of the Sochi Winter Games.
The Sochi organising committee said the torch relay reached the North Pole on October 19.
Russian polar explorer Artur Chilingarov, who led the mission, lit a special bowl at the North Pole sign. The ceremony involved 11 torch-bearers from several countries.
The icebreaker, which departed from Russia's Arctic port of Murmansk, made the journey in about 91 hours, the quickest such trip.
For most of the 39,000-mile torch relay, the longest in the history of the Olympics, the flame travels by plane, train, car and even reindeer sleigh, safely encased inside a lantern.
