Robles beat the previous record of 12.88sec set by China's Olympic champion Liu Xiang on July 11, 2006 in Lausanne, Switzerland. Liu could only finish in fourth place here.

"What a time! I wasn't expecting that," said Robles. "I'm very happy. I don't know if I can beat Liu Xiang in Beijing. But we'll see."

The 21-year-old Cuban, a silver medallist over 60m hurdles at the world indoor championships in 2006, missed out on a medal at this year's event in Valencia in March when he pulled up, thinking Liu had made a false start.

He has been targeting Welshman Colin Jackson's long-standing 60m indoor record of 7.30sec, running a 7.33sec this winter. He also set the world lead of 12.92sec last year.

"When he ran 7.33sec indoors, I knew he was capable of beating both the indoor and outdoor records," said Robles' coach Santiago Antunez.

"He was feeling great and I was expecting something magical. To beat a world record, you have to have a perfect race, almost faultless. It has been easy here."

Roaring out of the blocks, Robles left the field for dead, double Olympic and world silver medallist Terrence Trammell of the United States coming in second at 13.21sec.

"Everyone's surprised," said the American. "Nobody was expecting such a race."
