According to Yahoo News:
The World Anti-Doping Agency said Sunday it was “very alarmed” by new accusations of mass doping that have plunged athletics into a deep crisis.
WADA president Craig Reedie said the new claims would “shake the foundation” of athletes trying to stay clean.
German television channel ARD and Britain’s Sunday Times newspaper said they had been leaked a database belonging to athletics governing body the International Association of Athletics Federations (IAAF) with details of 12,000 blood tests from 5,000 competitors which revealed “extraordinary” levels of doping.
