Saif Saeed Shaheen of Qatar shattered the world steeplechase record at the Golden League meeting on Friday to ease the disappointment of being banned from the Olympics by his former federation Kenya.
The 21-year-old world champion, who emigrated to Qatar for economic reasons, clocked seven minutes 53.63 seconds.
Formerly known as Stephen Cherono, Shaheen was 40 metres ahead at the bell and completed the last lap in 63 seconds to better the world mark of 7:55.28 set by Brahim Boulami of Morocco at the same meeting in 2001.
Shaheen, who was issued with a Qatari passport last year, has been unbeaten for almost two years and won the 2003 world title in Paris.
"I had it in my mind that the record was possible," he told reporters. "But you don't go for the world record every time. I told the pacemakers to take me up to 2,000 metres and 5:18, after that I would race alone."
He said it had not been a pleasant feeling missing the Athens Olympics, even though he filled the time training three times a day.
"I was a little bit frustrated, I guess. I had been waiting for the Olympics, it was a bad feeling, I wasn't happy."
Russian Olympic champion Yelena Isinbayeva set a second world record of the night when she broke her own mark set in Athens. Isinbayeva succeeded with her third attempt at 4.92 metres, her seventh world record of the year.
