Usain Bolt claimed his 13th global gold medal with an emphatic 200 metres victory at the World Championships in Moscow.

The Jamaican stormed to glory in 19.66 seconds, six days after taking the 100m title.

Compatriot and training partner Warren Weir claimed silver in 19.79secs, with American Curtis Mitchell getting bronze in 20.04.

While Bolt had a fight on his hands to beat Justin Gatlin in the 100m final, in this one there was only one winner from the moment he came out of the blocks.

The 26-year-old was away and gone as he flew off the bend and powered away down the straight to claim his third straight world 200m title.

He celebrated by dancing on the track with Weir to Bob Marley's 'Three Little Birds'.
