Medals will not be awarded Monday in two events at the Sochi Winter Olympics, after heavy fog forced organizers to postpone competition.
The men's biathlon 15-kilometer mass start is now scheduled for Tuesday, after being delayed by fog for a second day.
Officials also postponed the men's snowboardcross preliminary rounds and final because of the fog, but did not immediately announce a new time for the event.
The changes leave five medal events set for Monday, including a showdown in the ice dance competition between Canada and the United States.
Americans Meryl Davis and Charlie White lead the competition going into the decisive free dance, but face a stiff challenge from Canadians Tess Virtue and Scott Moir.
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 a record in winning the Gold, defeating two teammates, favorite Ireen Wust, who finished second, and Lotte van Beek.
Norwegian skier Kjetil Jansrud won the men's super-G. 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. Sweden took the gold in the men's four by 10-kilometer cross country relay.
The top five nations leading the total medals race at the end of Sunday's competition are Netherlands with 17, host Russia and the United States with 16 each, and Norway and Canada with 14 each. Germany leads the gold medal count with seven, followed by Netherlands, Norway and Switzerland with five each.
