The International Association of Athletics Federation expressed grief Wednesday over the death of Kenyan athlete Nicholas Bett in a car accident.

In 2018, Bett had a season's best record of 48.88, and reached the 400-meter hurdles finals at the Commonwealth Games on the Gold Coast, as well as the African Championships in Asaba.

"The IAAF is deeply saddened and shocked to hear that Kenya's 2015 world 400m hurdles champion Nicholas Bett, 28, died in a car accident on Tuesday 7," IAAF posted on its Twitter account.

As he returned home after taking part in the African Championships held in Nigeria, the car Bett was traveling in near Nandi, Kenya, veered off the road Tuesday after hitting a pothole.

Bett earned the gold medal at the 2015 Beijing World Cup with a Kenyan record of 47.79, the best world record of the year.
