Genzebe Dibaba, Ethiopian runner, breaks indoor mile world record
Canada's Tim Nedow earns shot put gold in Stockholm
Genzebe Dibaba set a new world record in the indoor mile on Wednesday, beating a record that had stood for 26 years
The Ethiopian's time of 4 minutes, 13.31 seconds beat Doina Melinte's record set in East Rutherford, New Jersey, in 1990 by nearly four seconds. It was the third consecutive year Dibaba had set an indoor world record in Stockholm, having previously set the 3,000 and 5,000 metre records.
On a night of record breaking, Djibouti's Ayanleh Souleiman also set a new indoor record for the 1,000, streaking away on the final lap of the race to clock 2:14.20.
The previous record of 2:14.96 had been set by Denmark's Wilson Kipketer in 2000.
Souleiman's time still needs to be ratified by the ruling IAAF.
Canadian Tim Nedow threw a personal best 21.33 metres to win the men's shot put, beating Poland's Michal Haratyk into second and German Lauro of Argentina into third.
In the 500 metre race, Abdalelah Haroun of Qatar dug deep to finish in a world's best time of 59.83 seconds ahead of Onkabetse Nkobolo of Botswana.
Meanwhile, 39-year-old Kim Collins from Saint Kitts and Nevis proved once again that age hasn't diminished his speed winning the 60 metre sprint in 6.56 seconds, ahead of Americans Mike Rodgers and Joseph Morris.
In other events on a dramatic night, Adam Kszczot of Poland finished strongly to overtake Qatar's Musaeb Balla on the home straight to win the 800 metres in a world leading time of 1:45.63. Mohamed Aman of Ethiopia was third.
In the 3,000 metres, Morocco's Abdalaati Iguider of Morocco was strong enough to hold off the challenge Yomif Kejelcha of Ethiopia to win in 7:39.04.
Meanwhile, world championship silver medallist Shara Proctor was beaten into third place in the long jump by fellow Briton, Lorraine Ugen. KsenijaBalta of Estonia won the event with a season's best 6.76 metres.
