Two Kenyans fail drugs tests

Two Kenyans have failed pre-competition drugs tests at the world championships in Beijing and have been provisionally suspended, the IAAF announced Wednesday.

Koki Manunga and Joyce Zakary "have accepted provisional suspensions following positive samples provided in Beijing on the 20th and 21st of August respectively", the IAAF said in a statement.

Track and field's world governing body said the Kenyan pair had been tested at the athletes' hotel before their competition started as part of "targeted tests".
