But Russia's Sports Minister Vitaly Mutko was barred from attending the Games and the IOC ordered a disciplinary commission to look into his ministry's role in what a report called a state-dictated failsafe system if drug cheating.

The IOC executive held emergency talks yesterday on a bombshell inquiry commissioned by the World Anti Doping Agency (WADA) into the state doping at the Sochi Winter Olympics and other major events in Russia.

The IOC said it would not give backing to any international events in Russia because of the scandal but had to put back a decision on whether to bar Russia from the Rio Games which start August 5th.

WADA has called for Russia to be banned from international competition. And IOC president Thomas Bach called the doping scandal a shocking and unprecedented attack on the integrity of sport and on the Olympic Games.

But the IOC said it will explore the legal options with regard to a collective ban of all Russian athletes for the Olympic Games 2016 versus the right to individual justice.

The Olympic leadership said it will also have to wait for a Court of Arbitration for Sports decision ruling Thursday on an appeal by 68 Russian athletes against an IAAF ban from competition.

Russian minister barred

Lead investigator Richard McLaren said Monday he had conclusive evidence that the four year doping scheme was directed by the sports ministry with the FSB intelligence agency.

The IOC said it will not grant any Rio accreditation to any official of the Russian Ministry of Sport or any person implicated in the (McLaren) report. That includes Mutko, who has denied that the government directed the doping programme.

Mutko has already suspended five top deputies, including his number two Yury Nagornykh, described as the point man for running the cheating scheme. The IOC is now racing against the clock to reach a final position on the status of Russian athletes in Rio.
