MOSCOW — Eight Russian weightlifters have been banned for breaking anti-doping regulations, the country's anti-doping agency (RUSADA) said Tuesday. Denis Shiryakov was banned for life and Maxim Matveyev for four years while six others were suspended for periods of up to two years. “The Russian weightlifting federation (RWF) banned the eight athletes for breaching anti-doping regulations,” the agency said on its website (www.rusada.ru) without giving further details. Russia has been forced to step up its fight against doping in recent months after being criticised by international anti-doping officials for being too soft on drugs cheats. — Reuters
