A group that oversees the anti-doping program for international sports claims that Kenyan athletes are receiving help from local medical professionals to conceal drug violations.
Two athletes used similar explanations to explain medical anomalies, leading the Athletics Integrity Unit (AIU) to the same conclusion.
Eglay Nafuna Nalyanya and Betty Lempus, the runners, allegedly used fake documentation to prove they received an intramuscular injection at the same medical facility.
Last week, Athletics Kenya revealed that it had been granted $5 million (£4 million) year to fight doping.
