Norway's Emil Svendsen denied Martin Fourcade a third gold medal of the Sochi Games with a dramatic photo-finish victory at the end of Tuesday's men's biathlon 15km mass start.

Svendsen, himself a double gold medallist at the Vancouver Games in 2010, fought back in the finish straight and thrust one ski over the line to pip the Frenchman, with both men recording the same 42 minutes 29.1 seconds finish time.

Fourcade had already won gold medals in the 20km individual and 12.5km pursuit in Sochi, and looked dejected having initially believed he had done enough to win a third.

Ondrej Moravec of the Czech Republic took bronze for his second medal of the Games after winning silver in the 12.5km pursuit.

Tina Maze earned her second gold medal at the Sochi Games with victory in the women's giant slalom in difficult conditions.

The Slovenian, who made history by sharing the top of the podium with Dominique Gisin in the downhill last week, claimed the outright win in the pouring rain with an overall time of two minutes, 36.87 seconds in her two runs.

That was just 0.07secs ahead of Anna Fenninger, who won gold at the super-G over the weekend, while defending champion Viktoria Rebensburg settled for bronze.

South Korea claimed their first short track gold medal of the Games with victory in the 3000m ladies final.

Italy were awarded bronze after China were disqualified for impeding Korean skater Shim on the final lap.

Pierre Vaultier edged out home favourite Nikolay Olyunin on the last jump in the final of the men's snowboard cross to win gold at a murky Rosa Khutor Extreme Park.

The Frenchman triumphed despite the heavy rain, with visibility also difficult towards the start of the course due to the heavy fog that delayed the event by 24 hours.

Alex Deibold secured bronze in a tense final race, but fellow American Nate Holland - the reigning champion at the prestigious Winter X Games - failed to progress beyond the quarter-final stage.

Great Britain's men's curling team won through to the semi-finals in nail-biting fashion with a last-end 6-5 tie-break win over Norway at the Ice Cube Curling Center.

David Murdoch's all-Scottish rink, one of the main British hopes for a medal in Russia, had been beaten by the Norwegians in their round-robin fixture and played catch-up for most of the game, until his brilliant final stone in the 10th end secured two game-winning points.

GB will now play Sweden on Wednesday night, with the winners taking on either China or Canada in the final on Friday.
