LAUSANNE, Switzerland (AP) FINA wants British daily The Times to share evidence backing up its claims of widespread doping in Russian swimming.
FINA says it will investigate any allegations ''substantiated by evidence and which have not already been addressed.''
The newspaper on Wednesday alleged doping and cover-ups in Russian swimming linked to sports doctor Sergei Portugalov, who the World Anti-Doping Agency wants banned for life after investigating a doping conspiracy in athletics.
The reports quoted unidentified witnesses who suggested their fear of being named as whistleblowers.
FINA says it is ''not aware of any concrete evidence of systemic doping in Russian swimming,'' and defends its ''particularly robust approach to our anti-doping procedures.''
FINA previously gave Russian President Vladimir Putin its highest award months before Kazan hosted the 2015 world championships.
