LAUSANNE, Switzerland (AP) — The International Olympic Committee says 31 athletes in six sports have tested positive in reanalysis of their doping samples from the 2008 Beijing Olympics.
The IOC says it has opened disciplinary proceedings against the unidentified athletes from 12 countries.
The samples had been stored at the IOC laboratory in Lausanne. They were retested using enhanced methods on athletes who were expecting to compete at the Olympics in Rio de Janeiro in August.
The committee says "all those athletes infringing anti-doping rules will be banned from competing" in Rio.
It says the results of 250 retests from the 2012 London Olympics will "come shortly."
The committee will also undertake a "wider retesting" of medalists from Beijing and London.
