Russia's anti-doping tzar Yuri Ganus on Wednesday blasted the "irresponsible and destructive actions" of Moscow authorities he accuses of doctoring key data handed over to the World Anti-Doping Agency.

Ganus told delegates at WADA's world conference in Katowice that the anti-doping agency RUSADA he heads had become "a hostage to the crisis" triggered by the falsified information.

In September, WADA ordered Russia to explain "inconsistencies" in some of the thousands of files and samples handed over from its Moscow anti-doping laboratory in January.

Among delegates listening to Ganus's speech was Russian Sports Minister Pavel Kolobkov, who earlier had assured the conference that RUSADA and Russian authorities had met all of WADA's demands.
