IOC president Thomas Bach raised concerns about the international anti-doping system on Wednesday (21st June) and said Russian athletes who were allowed to compete in the Rio Olympics by the IAAF would do so under the Russian flag.

SOUNDBITE: (English) Thomas Bach, IOC president:

"The summit has also recognised that the anti-doping system has some deficiences that we have to make responsibilities clearer, that it has to be more transparent. Everybody has to understand better who is doing what and who is responsible for what. And that this needs a full review of the anti-doping system."

SOUNDBITE: (English) Thomas Bach, IOC president:

"If there are athletes qualified, then they will compete as members of the team of the Russian Olympic Committee because only a national Olympic committee can enter athletes to the Olympic Games. There are no teams of international federations there and, contrary to the national federation of track and field (ARAF), the Russian Olympic Committee is not suspended."
