* Jamaican adds 200 metres gold to 100m title
* Felix pulls up injured early in race
* Second silver for Ivorian Ahoure (adds detail)
Jamaica's Shelly-Ann Fraser-Pryce completed a brilliant world championship sprint double on Friday as she added the 200 metres gold to the 100m title but her path to glory was eased by an injury to Olympic champion Allyson Felix.
Fraser-Pryce, twice Olympic 100 metres champion, ran a brilliant bend and was always in command, coming home in 22.17 seconds to become the first woman since Katrin Krabbe in 1991 to win the world sprint double. American Kelly White did win both races in 2003 but was retrospectively disqualified for doping.
Ivory Coast's Murielle Ahoure, who became the first African woman to finish on the podium in a sprint at the world championships when second in the 100m, got a second silver but only just.
She and Nigeria's Blessing Okagbare were both timed at 22.32 but Ahoure took it by sixth thousandths of a second, leaving Okagbare to add bronze to the silver she won in the long jump.
Felix, who had been hoping to become the first athlete to win nine world golds, pulled up with a hamstring injury halfway round the opening bend. She fell to the floor and was eventually carried from the track by her brother Wes.
Fraser-Pryce, who ran in shocking pink spikes matching her flowing hair extensions, won the 100 metres gold medal at last year's Olympics and took silver in the 200 behind Felix.
