MONTREAL, AP:

Russia and Turkey produced the most doping violations, with athletics and weightlifting leading the sports with the highest number of cases, according to a report by the World Anti-Doping Agency.

The WADA report found that 1,953 sanctions were handed out for doping violations committed in 2013. The cases involved athletes and support personnel in 115 countries and in 89 sports.

WADA said it was the most comprehensive set of doping statistics compiled to date.

"With close to 2,000 sanctions in one year, and almost every sport represented, it's evident that doping still represents a huge threat to modern-day sports," WADA president, Craig Reedie, said in a statement.

Violations

Russia led all countries with 225 violations, followed by Turkey with 188 and India with 90.

Athletics produced 280 violations, followed by weightlifting with 252 and cycling with 203.

The report covers both positive drug tests and so-called "non-analytical investigations", which includes biological-passport cases that rely on monitoring of athletes' blood profiles for evidence of doping.

Of Russia's 225 cases, 42 were in athletics. In Turkey, there were 53 violations in athletics and 48 in weightlifting.

WADA set up a three-person independent commission in December to investigate allegations made in a German television documentary of widespread doping and cover-ups in Russia, particularly in track and field. Numerous Russian race walkers have been sanctioned for doping in recent years.

The WADA commission, headed by former president Dick Pound, is scheduled to deliver its findings by the end of the year.
