Olympic champion Ruth Jebet smashed the world record for the women's 3,000 metres steeplechase by more than six seconds at the Paris Diamond League meeting on Saturday.
The 19-year-old, who was born in Kenya and runs for Bahrain, clocked eight minutes 52.78 seconds, more than nine seconds ahead of Olympic silver medallist Hyvin Kiyeng Jepkemoi of Kenya who finished second.
The previous record of 8:58.81 was set by Russian Gulnara Galkina at the Beijing Olympics eight years ago.
Jebet narrowly missed out on the world record when she won Bahrain's first-ever Olympic gold medal in Rio de Janeiro this month.
It was clear that the world record was in danger after Jebet completed the first kilometre in 2:56.36. She went through the second kilometre in 5:54.16 compared to Galkina's split time of 6:01.20 in her record-breaking run in Beijing.
