Usain Bolt defended his 200 m title with ease and took his tally of World Championship gold medals to seven.
The Jamaican set a world leading time of 19.66 seconds at the World Atheltics in Moscow to secure his third successive world title in the event.
Usain Bolt’s compatriot Warren Weir clinched silver with a personal best 19.79 while America’s Curtis Mitchell (20.04) took bronze by a hundredth of a second.

His winning time was nearly five tenths slower than his personal best, the world record time of 19.19 he set in Berlin, and the slowest of his gold-medal wins over the distance.
But with Tyson Gay absent through suspension and his compatriot Johan Blake injured, Usain Bolt did not have to produce a vintage display to secure the result the vociferous sell-out crowd in the Luzhniki Stadium expected.
By the time the world record holder celebrates his 27th birthday on Wednesday, he could see his name alongside Americans Carl Lewis, Michael Johnson and Allyson Felix as the most decorated gold medallist in the championships’ history.
The speed of Usain Bolt’s progress to the top of that list of high achievers depends on Sunday’s 4×100 m sprint relay final.
South African athlete Oscar Pistorius will not compete again this year as he awaits trial for murder of his girlfriend Reeva Steenkamp.
Paralympic gold medallist Oscar Pistorius, 26, is on bail after being charged with the murder of 29-year-old Reeva Steenkamp but can compete before his court case is heard.
His agent, Peet van Zyl, said the six-time Paralympic champion was not mentally ready to return to the track.
“There was never any pressure from me or his coach (Ampie Louw) to return, it’s his decision,” said Peet van Zyl.
It means Oscar Pistorius will not compete in the IPC World Championships in Lyon in July.
Oscar Pistorius was arrested after shooting Reeva Steenkamp dead on February 14 and has not competed since.

The double amputee, known as Blade Runner because of the carbon fibre prosthetic blades he races in, claimed he mistook Reeva Steenkamp for a burglar and has denied murder.
On February 22, Oscar Pistorius was granted bail and had certain conditions lifted which meant he could compete in events outside his homeland.
Coach Ampie Louw was quoted by Eye Witness News in South Africa as saying his athlete was “nowhere close” to being in a position to train.
Oscar Pistorius had not been invited to compete in July’s London Anniversary Games, with UK Athletics chairman Ed Warner saying he did not want the meeting to turn into a “media circus”.
However, Oscar Pistorius’s agent said plenty of meeting organisers had been in touch to invite athlete to compete in their events.
“[There] were a good number, enough to keep him busy through the year,” added Peet van Zyl.
At London 2012, Oscar Pistorius became the first double amputee to run at an Olympics, taking part in both the 400 m and 4×400 m relay.
He then won gold medals in the T44 400 m and T42-46 4×100 m at the Paralympics, as well as silver in the T44 200 m.
Oscar Pistorius is next due in court on June 4 and a trial is expected to take place before the end of this year.
