The Ethiopian backed off the pace in his early laps before dashing to the front with one lap to go, a move that saw him floating away from his closest challenger, Eritrean Zersenay Tadese, on his way to setting a championships record of 26-minutes and 45.11 seconds.
"It’s great to win for the fourth time. I am so happy. I planned already to stay behind until one lap is left, and then kick," Bekele said.
Tadese was second in 26:50.12, while Kenya’s Moses Masai ran home strong for the bronze in 26:57.39.
Meanwhile, Spain’s Marta Domínguez clocked a world leading 9:07.32 to win the women’s 3,000m Steeplechase.
Domínguez fought her away through the pack on the last lap to take the event over Russia’s Yuliya Zarudneva (9:08.39) and Kenya’s Milcah Chemos Cheywa (9:08.57), who both ran personal bests for silver and bronze, respectively.
"I liked the pace of the race. But when Ghribi changed the pace I got nervous," Domínguez said.
"But I pushed myself to stay with her and Galkina. When I ran side by side with Galkina I realized that she was not breathing good and so I knew that I had a medal for sure."
Russian favourite Gulnara Galkina suffered breathing problem and faded into fourth with a seasonal best of 9:11.09, with Jennifer Barringer setting an American and Area record of 9:12.50 for fifth.
In field event competitions, Slovenia’s Primož Kozmus capitalized on a faulty day by Hungarian favourite Krisztián Pars.
Kozmus threw 80.84m to take the gold over Poland’s Szymon Ziólkowski (79.30m) and Russia’s Aleksey Zagornyi (78.09m).
"I would have liked to throw a better mark, but I am happy I won," Kozmus said.
The women’s triple went to none other than the defending champion Yargeris Savigne, who led home a Cuban 1-2 finish.
Savigne jumped 14.95m for the gold to beat Mabel Gay (14.61m) and Russian Anna Pyatykh (14.58m).
