IOC focuses on Russia, Kenya, Mexico in doping probe
Organization also targeting samples from 2008, 2012 Olympic medallists
The IOC is stepping up its drug-testing program ahead of the Olympics in Rio de Janeiro to focus on athletes from Russia, Kenya and Mexico.
The IOC executive board adopted a resolution Wednesday promising to take "further decisive action" in the fight against doping.
Its budget for pre-games testing ahead of the Rio Games will be doubled and there will be a "special focus" on countries whose anti-doping program is non-complaint with global rules, naming Russia, Kenya and Mexico.
The IOC also will widen its retesting program of stored samples from the 2008 and 2012 Olympics, saying it will target medallists from both games for possible reanalysis.
Fifty-five positive tests have already been recorded in retesting of samples from the Beijing and London Games.
