Lausanne (AFP) – The International Olympic Committee on Thursday stripped three Kazakh weightlifters of gold medals won at the London 2012 Games for doping.

Zulfiya Chinshanlo, Maiya Maneza and Svetlana Podobedova were all caught in new testing of hundreds of samples from the London and 2008 Beijing Olympics.

A weightlifter from Belarus who won a bronze medal medal was also disqualified by the IOC. Russian weightlifter Besik Kudokov who won a silver in London also failed a doping test but the medal was not taken away because he died in 2013.
