Bahrain's Kenyan-born Ruth Jebet produced an astonishing piece of front running to win gold in the Olympic women's 3000m steeplechase on Monday.

Jebet timed an Asian record of 8min 59.75sec, missing out on the world record by less than a second.

Reigning world champion Hyin Kiyeng Jepkemoi of Kenya took silver in 9:07.12, with American Emma Coburn claiming bronze (9:07.63).
