New Delhi: The International Association of Athletics Federations (IAAF) on Wednesday provisionally suspended two Kenyan athletes after the duo failed drug tests at the ongoing Beijing World Athletics Championships.
Athletics' world governing body confirmed that the pair, Joyce Zakary and Koki Manunga, were tested on August 20 and 21 ahead of the Beijing event under its recently adopted target tests.
Zakary, 29, set a new Kenyan national record in the women's 400m heats but then conspicuously pulled out of the semi-finals despite having the eighth best qualifying time. 400m hurdler Manunga on Sunday finished sixth of seven, and failed to reach the semi-finals.
Further reports in Kenyan media claimed that both Zakary and Manunga have tested positive for a masking agent for an unknown substance. Currently, as many as 13 Kenyan athletes are serving doping suspensions.
The sport has been hit by doping allegations following revelations from German broadcaster ARD and The Sunday Times newspaper in Britain, which claimed that they had obtained access to 12,000 suspicious blood tests involving 5,000 athletes.
The World Anti-Doping Agency (WADA), in the following up action, recently announced it would begin an "urgent" investigation into allegations of widespread doping in athletics.
After four days of competition at Bird's Nest, Kenya are leading the medal table with four golds, three silvers and two bronze.
