Slovenian skier Tina Maze has won her second gold medal at the Winter Olympics in Sochi, Russia, after taking first place in the women's giant slalom.

Her win Tuesday follows a gold medal run last week in the downhill. Austria's Anna Fenninger took second place Tuesday for her second medal of the games, while Germany's Viktoria Rebensburg won the bronze.

Earlier, France's Pierre Vaultier won gold in the men's snowboardcross, which had been postponed from Monday because of heavy fog. Russia's Nikolay Olyunin won silver and American Alex Deibold won the bronze.

In another event affected by fog, Norway's Emil Hegle Svendsen narrowly beat Frenchman Martin Fourcade to win biathlon gold in the men's 15-kilometer mass start.

South Korean speed skaters won gold in the women's 3,000-meter relay, with Canada taking silver and Italy earning bronze.

Later Tuesday, American freestyle skier David Wise, the world champion, is favored to win gold in the inaugural halfpipe event.

Russia and the U.S. have won 19 medals apiece at Sochi, just ahead of the Netherlands at 17 and Canada at 16. Germany has won the most gold medals with eight, followed by six countries with five each.
