Turkey's 10,000m silver medallist Abeylegesse won a second Olympic silver in the women's 5,000 meters at the Beijing Olympics.
Ethiopia's Tirunesh Dibaba won gold medal for the first long-distance running double in 28 years.
Dibaba, who last week won the 10,000m, finished in 15min 41.40sec, with Abeylegesse claiming silver in 15:42.74.
Defending champion Meseret Defar finished in bronze medal position at 15:44.12.
Dibaba's double is a landmark for women athletes and the first since male compatriot Miruts Yifter's feat over the same events at the 1980 Moscow Games.
