The doping scandal surrounding Russia’s track and field team is spreading into the international track and pool, with the country’s athletics federation admitting it was aware of several doping cases and taking action.
The Russian Olympic Committee announced Thursday that a number of athletes had tested positive for doping and was working with anti-doping authorities in the country.
The news comes as Russia prepares to host the 2018 and 2022 Winter Olympic Games, where the country has not been invited to compete.
The IOC is also expected to announce on Friday that the 2018 Rio Olympics will be moved to Moscow.
The World Anti-Doping Agency announced last week that it was conducting an independent investigation into allegations of Russian athletes using banned substances during the Sochi 2014 Winter Olympics.
The agency said the IOC would conduct its own probe into those allegations.
Russian officials said Friday that it is “absolutely not possible” for the country to host any Olympics because of the doping situation.
The country’s top sports official, Vitaly Mutko, has said Russia has not seen any evidence of doping since the end of the Sochi Winter Olympics in February, and has blamed the countrys doping system on Western interference.
The International Olympic Committee also has not ruled out holding a Winter Olympics event in Russia, and said it is working to resolve the doping crisis in the sport.
