World 10,000m winner Tirunesh Dibaba successfully defended her 5,000m crown on Saturday to become the first woman to clinch the historic double. The Ethiopian set a new championship record of 14 minutes 38.59 seconds.
Dibaba's team-mate and Olympic 5,000m champion Meseret Defar took silver and her elder sister Ejegayehu got bronze.
Meselech Melkamu was fourth, sealing only the second one-two-three-four in history - the feat was also achieved by America in Thursday's men's 200m final.

"I wanted to win both races and I did," said Dibaba. "I'm planning to do that next time again."
"Doing top four is the best feeling that you can hope for. It's a dream come true and I'm very happy."
Defar went with Dibaba at the bell but fell away around the final bend and finished in 14:39.54.
Ejegayehu, who also took bronze in the 10,000m, crossed the line in 14:42.47.
Britain's Jo Pavey finished a disappointing 15th in 5:14.37 and she admitted she never felt in it.
"I've been feeling a bit dodgy but I just didn't feel myself," Pavey told BBC Sport.
"I just couldn't run - I've been worried about it for a few days.
"As soon as the gun went I just didn't feel myself.
"I'm really disappointed and kept pushing on because I wanted to finish. I just felt really rubbish.
"You feel bad when people have supported you to get here and then you run poorly. I need to speak to the medical people."
