Stavanger - Hana Mazi Jamnik, an up-and-coming cross-country skier, has been killed in a traffic accident during training in Norway, the Slovenian Ski Association said on Thursday.

The 19-year-old was roller skiing through a tunnel on the road between Forsand and Joerpeland in south Norway when she was hit by a lorry.

She was badly injured in the crash and airlifted to a hospital in Stavanger, where she died, according to Sportal, a sports news website.

A police spokesman told the website norway.posten.com that the lorry driver was in police custody and had undergone a blood test to see whether he was driving drunk.

Mazi Jamnik was one of the best young cross-country runners and roller skiers in the world.

She won gold and silver at the Roller Skiing Junior World Championships last year.
