INTERNATIONAL: The B-sample of Russian figure skater Kamila Valieva is yet to be analysed at the Beijing Olympics despite an initial positive drug test, the International Olympic Committee said on Tuesday.

Russian figure skater Kamila Valieva said the days leading up to her being cleared to compete in the women's singles event at the Beijing Games on Tuesday despite having tested positive for a banned substance had left her emotionally fatigued.

"These (past few) days have been very difficult for me," the 15-year-old told Russia's Channel One in her first comments about the situation.

"It's as if I don't have any emotions left. I am happy but at the same time I am emotionally tired."

The teenager was cleared to compete in tonight’s single event after a Court of Arbitration for Sport (CAS) ruling that agreed with the Russian Anti-Doping Agency's (RUSADA) decision to lift a ban on her.

If Valieva finishes in the top three of the women's single event, the medal ceremony will not be held at the Olympics, prompting outrage from athletes and officials around the world.
