The decision came a week after the IOC banned Russia from next year's Pyeongchang Winter Olympics for what it called "unprecedented systematic manipulation" of the anti-doping system.

The IOC, however, left the door open for Russian athletes with a clean history of non-doping to be invited to compete in Pyeongchang as neutrals.

The banned ice hockey players are Inna Dyubanok, Ekaterina Lebedeva, Ekaterina Pashkevich, Anna Shibanova, Ekaterina Smolentseva and Galina Skiba.

"The Russian Team is disqualified from the Women's Ice Hockey Event and the International Ice Hockey Federation is requested to modify the results of the event accordingly," the IOC said in a statement on its website.

The Russian women's hockey team finished sixth at the 2014 Sochi Games.

The IOC decision increased the number of Russian athletes banned for life from the Olympics over alleged doping violations at the Sochi Games to more than 30.

The IOC did not disclose the nature of the hockey players' alleged doping violations. It also said it had closed a case against a seventh unnamed athlete without sanction.

Russia's Olympic Committee agreed earlier on Tuesday to support the athletes who choose to compete in next year's Winter Games in South Korea as neutrals.
