Kenya "clearly" has an athletics doping problem which may need a new investigation, Wada inquiry chief Richard Pound said Thursday.
Pound told a press conference he had not been able to look into Kenya or other suspect countries because he only had a mandate to investigate doping in Russia.
"We know that there is a problem," Pound told a press conference to present a new report on doping and corruption in world athletics.
"We have not investigated Kenya that was not part of our mandate," he said.
"There may be some other independent commission that would have a look at Kenya once some of the smoke clears. But we were not authorised to go any further with that."
But Pound said: "There is clearly a problem."
More than 40 Kenyan athletes have been suspended for doping in the past two years.
In December, three top Athletics Kenya officials including president Isaiah Kiplagat, deputy president David Okeyo and former treasurer Joseph Kinyua were suspended by the IAAF ethics Commission for alleged corruption and covering up doping.
