Kazakhstan says three medalists are among six of its athletes disqualified from previous Olympics over doping.
The country’s national Olympic committee said in a statement that weightlifters Irina Nekrasova and Maria Grabovetskaya, who won silver and bronze medals respectively at Beijing 2008, and bronze medal-winning wrestler Aset Mambetov, were retroactively disqualified following retests of drug-test samples they gave at those games.
There are also retrospective disqualifications from the 2008 games for weightlifters Vladimir Sedov and Maiya Maneza, while another weightlifter, Almas Uteshov, has been scratched from the 2012 Olympics. Those rulings do not affect medals.
Kazakhstan has one of the worst records of any country in the retests carried out this year by the International Olympic Committee.
