Ethiopia has conducted doping tests on more than 350 athletes, the vast majority of them track and field competitors.

Mekonnnen Yidersal, the director general of the Ethiopian National Anti-Doping Office, says the exercise was ''successful'' and a laboratory is expected to complete testing on the samples in 10 days.

Anti-doping authorities tested 339 track and field athletes last week. The tests coincided with the national athletics championships.

Mekonnnen says five Paralympic athletes, 10 cyclists, and five boxers were also tested.

Ethiopia's apparently weak anti-doping program came under the spotlight last year when the World Anti-Doping Agency urged it to carry out more tests. Ethiopia has also criminalized doping. Dopers can to be sent to jail for up to five years.
