Moscow - The World Anti-Doping Agency's allegations of widespread abuse of performance enhancing drugs among Russian athletes are "groundless," Russian President Vladimir Putin's spokesman says.
"Whenever any charges are made, there must be some evidence that they rely on. As long as there has been no proof, it is hard to react to any accusations, which look rather groundless," spokesman Dmitry Peskov told reporters, according to state news agency TASS.
"It's none of our business to ponder over the causes of such scandals," Peskov said in Sochi, where Putin is expected to attend some Olympic-related events with Russia's Sports Minister Vitaly Mutko this week.
Mutko said on Russian state television channel Rossiya-24 that half of the doping allegations were correctable and the other half lacked proof.
