Golden doubles by Shelly-Ann and Mo Farah

Dinesh Weerawansa reporting from Russia

MOSCOW, Aug. 17 - Jamaican woman sprinter Shelly-Ann Fraser-Pryce and British long distance runner Mo Farah completed golden doubles on day seven of the 14th IAAF World Championships here last night.

Bob Marley's popular songs rang around the Luzhniki Stadium in honour of the Jamaican lass after her brilliant run in women's 200m final in which the three-time gold medallist Allyson Felix of the USA crashed out with a hamstring tear.

Fraser-Pryce was never challenged, clocking an impressive 22.17 seconds into a slight headwind of -0.3m/s to add to the 100m title she had won so emphatically on Monday, confirming her standing as the world's leading female sprinter.

With Felix out of the medal equation, Murielle Ahoure of the Ivory Coast edged a photo-finish by six thousandths of a second from Nigeria's Blessing Okagbare after both were awarded a time of 22.32. It was Ahoure's second silver in sprints in Moscow 2013, having won the 100m silver four days ago. Okagbare completed her gruelling schedule with more precious metal, winning the silver in long jump silver and sixth place in the 100m final here.

Misfortune struck Felix, who was bidding to take her ninth gold medal at world meet which would have put her out on her own - one clear of Carl Lewis and Michael Johnson, as the most successful athletes ever in the 30-year history of the championships.

The American lass left the track carried by her brother and agent, Wes, with any hope of bettering their tally here in Moscow over. Felix had started sluggishly and after her leg appearing to visibly twitch in pain she dramatically pulled up and crashed to the track in a heap around the 60m mark.

Fraser-Pryce got off to her trademark blistering start and was already closing up on Okagbare on her immediate outside. Ahoure from lane seven was also making good early headway to suggest she would be a factor. Entering the home stretch, Fraser-Pryce, with her arms pumping at great speed and head slightly rocking, held a three-metre lead.

Ahoure was her nearest pursuer with Okagabare drawing upon her considerable strength starting to come into the picture. Midway down the home straight the African duo started to close, and for a moment it seemed that Fraser-Pryce would be threatened. However, she responded and with her pink hair extensions flowing behind her she let out a wide-eyed scream of joy as she crossed the line to secure the first women's 100m and 200m sprint double at the World Championships for 22 years.

Finishing behind the Jamaican in the women's 200m final were Ahoure and Okagbare who were locked in their own private duel. They both flashed across the line, only to be separated in a photo finish as it was not visible to the naked eye. Teenager Shaunae Miller,the youngest ever World Championships finalist in a women's 200m, drew upon the strength she has shown as a former World youth and World junior 400m champion to finish strongly in 22.74. It was for the first time since Athens 1997, that the USA failed to win a medal in women's 200m.

USA wins men's 4 x 400m gold

But the USA took control of the men's 4x400m final from the start of the race with their opener David Verburg bringing the baton to the first exchange in pole position. Anchored by LaShawn Merritt, the USA clocked two minutes and 58.71 seconds to take the gold. It accounted for this year's world's leading time that gave USA their fifth successive gold medal in the World Championships. In the second place was Jamaica with 2:59.88, followed by the hosts Russia in 2:59.90.

It was quite close at that stage though, with British first-leg runner Conrad Williams following close behind with Russia's Maksim Dyldin also in the picture. Belgium, who were represented by the three Borlee brothers on the first three legs, was also close with Jonathan running first. Kevin Borlee started fiercely on the second leg and for a moment was thinking of overtaking everyone at the end of the back-straight. He waited until the final straight though bringing Belgium to the second exchange in second place behind United States.

Farah takes 5,000m gold

Mo Farah completed that dream long distance double which was missing from his rich collection after Olympic triumph in London last year. Having missed it in Daegu two years ago, Farah produced an 800m-like final 600m to hold off a host of challengers in the 5000m on Friday night.

Farah pocketed the men's 5,00om gold in 13 minutes and 26.98 seconds, adding it to the 10,000m he won on the opening night of the championships.

Hagos Gebrhiwet of Ethiopia, who only turned 19 in May, stormed past Isiah Koech and Thomas Longosiwa in the final metres to grab the silver medal in 13:27.26. Koech took the bronze in the same time with Longosiwa a couple of metres back in fourth.

Edwin Soi, who beat Farah in Eugene earlier in the year, was next, then the veteran Bernard Lagat. Galen Rupp and Yenew Alamirew, tipped as the biggest threat to Mo with his closing speed, were further back.

Russian Tatyana strikes gold

Russian Tatyana Lysenko cleared 78.80m in the final to win the gold in women's hammer throw. The Olympic champion, had to be at her absolute best to edge Anita Wlodarczyk (78.46), who smashed the Polish record for silver with the fifth-longest throw ever - in what will go down as the greatest women's Hammer competition we have ever witnessed.

Zhang Wenxiu of China, with a season's best of 75.58m, secured her third World bronze, one place ahead of her countrywoman Wang Zheng, who set a personal best of 74.90m having gone into the final ranked the 12th best thrower. The first round plodded along with little to stir the senses until the defending champion stepped into the ring. Nine throwers had taken their turn in the circle before her with Jeneva McCall of the USA the pick of the bunch with a relatively modest 72.33m.

Cue Lysenko. The Russian powered the hammer out to a formidable opener of 77.58m - the second longest throw in World Championship history - to take an early grip on the competition. Zhang hit 74.62m with the final throw of the round to shift into silver after the opening vista. After a relatively low-key first round - Lysenko and Wenxiu apart, the competition stepped up a notch in round two. Yipsi Moreno, the three-time World champion from Cuba appearing in a record-breaking seventh World Championships final, nudged herself up to fifth with a season's best of 74.16m.However, the most notable mover was Wang, the Asian champion, whose 74.90m effort catapulted her into silver.

David Storl defy odds

Meanwhile, David Storl defied the odds after an underwhelming and sometimes erratic season to successfully defend the title he had won two years ago, the German sending his 16lb implement out to a season's best of 21.73m in the fourth round to clinch the victory. Storl once again proved his ability to produce his best, or very near to it, on the big occasion and added to his magnificent record over the last two years which now includes two World titles, a European title and silver medals at the other two major events: the 2012 IAAF World Indoor Championships and the London 2012 Olympic Games. US favourite and 2013 world leader Ryan Whiting threw down the gauntlet when he reached 21.57m with the first put of the competition, while Storl was the only other man to go over 21 metres in the opening round with 21.19m.

Whiting then fouled his second effort as Storl consolidated his second place with 21.24m. Canada's Dylan Armstrong and USA's 2007 World champion Resse Hoffa reached 21.10m and 21.12m respectively to establish the fact that the medals were likely to be decided between those four men.

Long jumper Aleksandr rise to the occasion

The men's long jump final saw Aleksandr Menkov rising to the big occasion to have his three jumps farther than anyone else, topped by a Russian record of 8.56m, to take the gold medal. Cheered on by an enthusiastic crowd and clearly motivated by the sight of his compatriot Tatyana Lysenko winning the women's Hammer gold medal while the competition was underway, Menkov showed the high-level consistency that he had done all year.

Such consistency marked him out as the favourite for the gold medal, regardless of a surprising defeat at the World University Games last month when he finished second to Mexico's Luis Rivera, despite jumping a personal best of 8.42m.

The 2010 European champion Christian Reif of Germany took an early lead when he went out to 8.18m in the first round with Menkov not that far behind, with 8.14m on his opening effort.Spaniard Eusebio Caceres then took over in pole position with 8.25m in round two. However, Menkov then uncorked a Russian record of 8.52m in the third round, consigning to history the previous mark of 8.46m set by Leonid Voloshin back in 1988.
