Olympic champions Norway beat South Korea 31-25 in the first women's handball semi-final to continue their dominance of the sport.

Marshalled by world player of the year Heidi Loke in attack and Katrine Haraldsen in goal they moved serenely into a second successive final and will face Montenegro.

Questioned about their teamwork and commitment during a lacklustre group campaign, Norway responded in the most determined fashion as they dominated their Asian opponents in all facets of the game.

While Korea's Sim Haein scored the game's first goal to barely any crowd reaction, Marit Frafjord hit back immediately with two of her own and twice Olympic champions South Korea never got the lead back.

Norway, who are also world and European champions, buzzed around the court and Loke top-scored with eight goals.

"Earlier in the championship we were not running so much, but we're in really good shape and we are now running all the time. This is the way Norway plays so we have to do that," said Loke.

Olympic handball debutants Montenegro beat Spain 27-26 on to set up a final against reigning women's champions Norway.

Montenegro, only officially recognised as an Olympic nation in 2007 and now with a chance to win the country's first gold medal, edged ahead in the second-half and will contest Saturday's final.

Spain, whose women's side are seeking a first medal, will play South Korea for the bronze.
