MOSCOW (Sputnik) — According to WADA's Anti-Doping Rule Violations Report, 148 out of 1,693 violations were made by Russian athletes, followed by Italians with 123 violations.
In December 2014, Germany’s ARD television broadcaster released the film titled "The Doping Secret: How Russia Creates Champions" on alleged doping abuse and corruption in Russian sports. Following the release of the film, WADA launched an investigation into the allegations of doping abuse in Russian sports.
In November 2015, WADA presented a report, accusing Russia of numerous breaches of global anti-doping regulations and recommended the country be banned from international athletics competitions, which then led to the All-Russian Athletics Federation (ARAF) suspension from the International Association of Athletics Federations (IAAF).
In March, a number of prominent Russian athletes were tested positive for meldonium, medicine added to the list of banned substances on January 1, 2016 by WADA.
Earlier this month, WADA revoked its accreditation of the Moscow anti-doping laboratory, citing the lab’s alleged non-compliance with the International Standard for Laboratories and related technical documents.
