Doping allegations called 'sensationalist and confusing'

The world governing body for athletics, the IAAF, fought back on Tuesday against media reports of suspected widespread doping in the sport, rejecting accusations it failed to investigate dubious drugs test results properly.

The IAAF said the reports by Britain's The Sunday Times newspaper and Germany's ARD/WDR broadcaster, which implied cheating was rampant in athletics, were based on "guesswork" and not facts.
