MOSCOW (AP) — Russia's athletics federation says three female athletes have been suspended for two years for doping violations.

Distance runners Svetlana Klyuka, Nailya Yulmanova and Yevgenia Zinurova were banned because of unspecified violations of anti-doping rules.

Klyuka's and Yualamanova's results since August 2009 have been annulled. Zinurova's showings since March 2010 have been invalidated.
