The 23-year-old Olympic and two-time world champion timed 26 minutes 17.53 seconds to break his old record of 26:20.31 set in Ostrava in June 2004.

While he succeeded two other world champions failed in their bids for world records as Russian pole vaulter extraordinare Yelena Isanbeyeva failed three times at 5.02 metres and Qatar's two-time steeplechase world champion Saif Saaeed Shaheen also missed out.

However, Isanbeyeva's compatriot Tatyana Lebedeva moved inexorably towards the 1million dollars Golden League bonus as the 29-year-old sauntered to victory in the triple jump and now she must win in Berlin on Sunday week and turn up at the Grand Prix finals later in September to collect.

Bekele, though, was the star of the show and it was made even more memorable as his 18-year-old brother Tariku paced a lot of the race for him.

"I was so happy that at the end we didn't find the right words but we didn't need them," said Tariku, who failed to medal in the 5000m final at the World Championships.

While Justin Gatlin overcame a poor start to once again stamp his superiority on the 100m his predecessor as the dominant force Maurice Greene cast a sad sight as the 31-year-old's miserable tour of Europe possibly reached its nadir.

The former world record holder and 2000 Olympic champion had promised he would finish under 10 -- he did though not quite as he intended as the 'Kansas Comet' finished ninth and last in a time of 10.56sec -- time perhaps for the sprinting great to give up the day job.

Another African to have opted to take money by transferring allegiance to a Gulf state Rashid Ramzi was brought crashing back to earth as Bahrain's Moroccan-born recently-crowned 1500m and 800m world champion was soundly beaten by Kenya's young hope Daniel Kipchirchir Komen.

The 20-year-old Kenyan, who failed to progress from the heats in Helsinki, was metres clear of the Bahraini, whose pretensions to replace former compatriot Hicham El Guerrouj as the king of the distance were brutally exposed.

Neseret Defar had set the stage for her compatriot Bekele earlier in the evening as she recorded the best time this year in the 5,000m and set a new African record with a time of 14min 28.98sec.

The 21-year-old Olympic champion -- who had to give second best to teammate Tirunesh Dibaba at the world championships -- lived up to her name which means 'bold' in Amharic as her front running style saw her come home well clear of fellow Ethiopian Berhane Adere and Dibaba's elder sister and dual world bronze medallist Ejegayebu.

America's up and coming women's 400m hurdler Lashinda Demus at last put one over her arch rival and world champion Yuliya Pechonkina as the 22-year-old American - who took silver in Helsinki -- came with a late run to overhaul 36-year-old compatriot Sandra Glover while the powerful Russian was third.
