Olympic champion Shelly-Ann Fraser of Jamaica exploded from the blocks and held on to win the world 100 metres gold medal with a time of 10.73 seconds at the World Athletics Championships in Berlin.
Compatriot Kerron Stewart took silver with American Carmelita Jeter snatching bronze.
As in last year's Olympics, Jamaica have now won both blue-riband 100 metres sprint events, after Usain Bolt smashed the world record to win gold with 9.58 yesterday.
