MOSCOW - Yelena Isinbayeva missed out on a world record but claimed her third pole vault world title in a thrilling final.
Before the biggest crowd of the Moscow championships, the Russian cleared 4.89m to claim victory but was unable to set a new world best of 5.07.
The 31-year-old helped create a magical atmosphere and celebrated wildly with the enthusiastic crowd.
America's LaShawn Merritt also reclaimed his 400m world title with a commanding performance.
It was expected to be a close race between Grenada's defending champion Kirani James, the reigning Olympic champion, and the American, but the battle never materialised as 2008 Olympic gold medallist Merritt won comfortably in 43.74 seconds.
James, 20, trailed 2009 champion Merritt by a distance coming off the bend and slipped into reverse as he meekly crossed the line in seventh in a time of 44.99.
United States' Tony McQuay took silver and Domican Republic's Luguelin Santos bronze.
In the men's discus final, Germany's Robert Harting picked up his third World Championship gold, to go with his London 2012 Olympic title.
Milcah Chemos Cheywa of Kenya claimed gold in the women's 3,000m steeplechase in a time of 9:11.65 to finish ahead of compatriot Lidya Chepkurui and Ethiopia's Sofia Assefa.
