Russian doping claims damaging athletics says Lord Coe

Lord Coe describes claims of systematic doping in Russian athletics as "damaging".

Coe, a candidate for the presidency of the International Association of Athletics Federations, called for independent testing to help tackle the issue of drugs in the sport.

The Russian Athletics Federation called the allegations by German TV "lies" while the IAAF is looking into further doping allegations made in a second German TV documentary on Sunday.
