Sprinter Usain Bolt has beaten Justin Gatlin to win the 100m title at the World Athletics Championships.
Bolt had stumbled out of the blocks in winning his semi-final but managed to run a season's best time of 9.79 seconds to win in the final.
Justin Gatlin had been unbeaten in 28 races and started off as favourite after running a fast time in his semi-final.
But there was no beating Usain.
The Jamaican took the title for the third time.
