Monte Carlo - The IAAF, the governing body of world athletics, has imposed two-year doping bans on eight Russian athletes for testing positive for the banned blood-booster EPO.

It emerged Thursday that the athletes include Vladimir Kanaikin, the 20-kilometre walk world record holder, and Alexei Voyevodin,
50km walk bronze medalist at the Athens Olympics in 2004.

Last month, seven Russian athletes were suspended for two years by the Russian Athletics Federation (ARAF) for tampering with doping samples.

The athletes named included Yelena Soboleva, who earlier this year set a world indoor record in the women's 1,500 metres and two-time world 1,500 champion Tatyana Tomashova.

The seven were provisionally suspended by the IAAF in July and five of the athletes were immediately removed from Russia's Beijing Olympic squad by the ARAF. (dpa)
