Pyeongchang, South Korea - The result of Sunday's chaotic men's pursuit race at the biathlon world championships in Pyeongchang could be contested in front of the Court of Arbitration for Sport (CAS), Russian media said on Monday.

The appeal jury of the sport's controlling body IBU on Sunday changed an earlier decision by race organizers to penalize the race winner Ole Einar Bjoerndalen and several other biathletes for leaving the track early in the race.

Seoul - South Korean Cardinal Stephen Kim Sou Hwan died Monday at the age of 86, media reports said.

Kim, who was the country's first Roman Catholic cardinal and played an important role in South Korea's democratization, died at Seoul's Saint Mary's Hospital, where he had been hospitalized for the past year.

He had been treated for pneumonia and complications for several months and had fallen into brief comas multiple times, the national new agency Yonhap reported.

Pyeongchang, South Korea  - Ole Einar Bjoerndalen on Sunday made history as he won the men's pursuit at the biathlon world championship in Pyeongchang - equalling the world record of 86 World Cup wins in the process.

There was, however, some doubt whether the results would stand as the race directors launched an investigation after Bjoerndalen and several others left the track for a while at the beginning of the race.

In the women's pursuit race, Sweden's Helena Jonsson stunned the favoured Germans taking the gold from Kati Wilhelm after a brilliant shooting display.

Pyeongchang, South Korea  - The world biathlon federation (IBU) announced on Sunday that Russian relay world champion Dmitry Yaroshenko failed a doping test in Oberhof in early January.

The IBU said that he has waived a B sample analysis and they now considered it to be a positive doping case.

"This case will be handed over to the IBU Doping Hearing as soon as IBU has received the complete documentation package from the laboratory," the IBU said.

This case will then be decided by the IBU Doping Hearing Panel.

Yaroshenko, who has now failed three doping tests this season, is one of three Russian biathletes who left the world championships before the start of the competition after testing positive.

Pyeongchang, South Korea  - Helena Jonsson on Sunday claimed the biathlon world championship gold in the women's pursuit after a near-flawless display on the shooting range in Pyeongchang.

The Swede stunned the favoured Germans in windy conditions missing just twice on the first shooting, but then hitting all the remaining targets, to move past Germany's Kati Wilhelm and win in a time of 34 minutes 12.3 seconds.

Wilhelm was 18.3 seconds behind.
