Triple Olympic champion Usain Bolt set a new world record as he cruised to a stunning victory in the 100 metres at the World Championships in Berling.

The 22 year old Jamaican stormed home in a time of 9.58seconds to shave 0.11 off the record he set last year when winning gold at the Beijing Olympics.

American Tyson Gay was second in a time of 9.71seconds, with Jamaica's Asafa Powell claiming bronze in 9.84seconds.

Bolt, who set three world records when winning his Olympic golds in Beijing last summer, served up another superlative display as he bounced back from his false start in the semifinals.

In the final, he powered out of the blocks at the first time of asking and took control of the race within the first 30 metres, the crowd going wild as he streaked across the line in another landmark time.
