Madrid's Anti-Doping Laboratory was reinstated by the World Anti-Doping Agency (WADA) on Friday, more than a year after it was suspended.

Computer hackers who leaked the medical records of more than 100 top athletes in a bid to reveal questionable drug exemptions may have tampered with the data, according to the World Anti-Doping Agency (WADA).

The World Anti-Doping Agency (WADA) says that another batch of athlete data has been leaked by the same Russian cyber espionage group that published confidential medical data earlier this week.

Russia should be banned from athletics competition, a World Anti-Doping Agency commission report has recommended.
