Five Russian Olympians suspended in doping scandal
Seven athletes in all, of which five were hoping to represent their country in the Olympics, have been provisionally suspended by the sport's governing body. The International Association of Athletics Federations says the womens’ tests, taken in 2007 and 2008, do not match.
The IAAF says the Russians will now face an official investigation and remain disqualified until the end of proceedings.
The scandal has cast a cloud over the Russian team just ahead of the Beijing games which are due to begin next week.
