American Noah Lyles posted another impressive 200m time to take victory in Saturday's Diamond League meeting in Paris.

The 22-year-old, who set a world-leading time in Lausanne last month, finished in 19.65 seconds in Stade Charlety.

Turkey's world and European champion Ramil Guliyev came second in a time of 20.01.

Jamaica's double Olympic champion Elaine Thompson won the women's 100m.

Lyles clocked 19.50 in the Lausanne meeting in July - the fourth-fastest time over 200m - to position himself alongside fellow American Christian Coleman as a possible successor to sprint legend Usain Bolt.

However, on Saturday Coleman was charged under anti-doping rules with missing three drugs tests. The US Anti-Doping Agency confirmed the 23-year-old had been charged with failing to "properly file his whereabouts information".

Coleman, who ran a world-leading time of 9.81 seconds in the Diamond League in California in June, has agreed to an arbitration hearing on 4 September, with Usada saying a decision will be made the following day.

If found guilty Coleman would face an automatic one-year ban, missing the World Championships in Doha and the Olympic Games in Tokyo next year.

Lyles will compete only in the 200m at Doha before attempting a sprint double at the Tokyo Olympics.

Thompson took first place in the women's 100m sprint in a time of 10.98, ahead of Ivorian Marie-Josee Ta Lou (11.13) and Dutch sprinter Dafne Schippers (11.15).

"It was a hard race," Thompson admitted. "It's still five weeks to Doha so it's all preparation at this stage.

"I'm not at 100% yet because it's all about the World Championships.

"It's very important to put races like this in because it was a strong field so to get the victory is great."
