ROSA KHUTOR, Russia (Reuters) - Marit Bjoergen laid down another marker as she claimed a record-equalling sixth Winter Olympics gold medal, leading a Norwegian sweep in the cross-country 30km freestyle at the Sochi Games on Saturday.

Bjoergen, the first Norwegian woman to win a 30km event at the Games, pulled ahead of Therese Johaug with a late burst of acceleration and Kristin Stoermer Steira took the bronze.
