Full coverage: 2016 Rio Olympics

While peace is being celebrated in Brazil, there has been some finger pointing between the World Anti-Doping Agency and the IOC. Monday, WADA defended the publication date of its report on doping in Russia, a day after the IOC blamed it for the uncertainty surrounding the country's athletes at the Rio Olympics.

WADA's independent report by Canadian Richard McLaren was published July 18th and outlined systematic state-backed doping in Russia which triggered a series of sanctions on the nation's athletes. WADA chief Craig Reedie acknowledged the report was destabilizing coming less than three weeks before the Games, but said given the seriousness of the revelations, they had to be published and acted upon without delay. WADA then demanded a blanket ban on all Russian athletes, but the IOC decided against that, leaving the decision up to the individual sports federations.

Sunday, IOC president Thomas Bach defended his organization by saying, "We are not responsible for the timing of the McLaren report, or for the fact different information that was offered to WADA a couple of years ago was not followed up." More than 250 Russian athletes from an original team of 387 have been cleared to compete but still await the green light this week from a three-member IOC panel that has the final say.
