Four countries won Olympic gold medals Sunday, with the Netherlands sweeping the top three places in the 1,500-meter women's speedskating event.

Dutch skater Jorien ter Mors set an Olympic record in the race at the Winter Olympics in Sochi, Russia, to win the gold medal. She defeated two teammates, favorite Ireen Wust, who finished second, and Lotte van Beek.

Norwegian skier Kjetil Jansrud won the men's super-G, followed by Americans Andrew Weibrecht and Bode Miller, who tied for the bronze medal with Canada's Jan Hudec. The 36-year-old Miller became the oldest Olympic Alpine skiing medalist.

The Czech Republic won its first gold medal of the Games when Eva Samkova, wearing a fake moustache for good luck, took the women's snowboarding cross event. The silver medal went to Canadian Dominique Maltais, while Chloe Trespeuch of France captured the bronze.

Sweden took the gold in the men's four by 10-kilometer cross country relay, one day after Swedish women won their event. Russia earned the silver medal, with President Vladimir Putin in attendance. France came in third.

The men's 15-kilometer mass-start biathlon race was postponed to Monday because of fog.

With 17, the Netherlands now has the most total medals, followed by the United States and host Russia with 16. Germany has the most gold medals with seven, followed by the Netherlands, Switzerland and Norway with five each.
