Russian Olympic Committee has said 14 of its athletes at the 2008 Beijing Olympics tested positive for doping during re-tests of their samples. Sports Minister Vitaly Mutko said the news of the positive tests certainly does not look good. But speaking in Moscow, Mr Mutko said the results are not an objective picture of Russia's doping situation. The country's athletes are currently banned from international competition. The Russian Athletics Federation said any athlete found to have used doping in previous years will not go to Rio. The IOC earlier said up to 31 athletes could be banned from the Rio Games.
