Country grappling with doping scandal
The head of Russia's anti-doping agency has resigned.
RUSADA's director general Ramil Khabriev steps down less than a month after the organisation was suspended from athletics.
That followed the publication of a World Anti-Doping Agency independent report which accused the country of widespread doping.
Russia's sports ministry have also announced there will be a new supervisory board to serve as "a guarantee of independence".
