Olympic champion Masai Russell broke the world record in the women's 100m hurdles at the Wanda Diamond League meeting in Zurich, clocking 12.09 seconds and edging out previous record-holder Tobi Amusan of Nigeria.

Masai Russell claimed a new world record at the Weltklasse Diamond League event in Zurich, dominating the women's 100 metres hurdles with a time of 12.09 seconds. The performance came just before another world record fell at the same meeting, when Alison dos Santos achieved a historic mark in the men's 400m hurdles.

Russell, the reigning Olympic champion, executed a near-flawless performance over the hurdles to shave 0.03 seconds off the previous world record. The achievement marked the culmination of a strong season for the athlete, who had narrowly missed breaking the record on two earlier occasions.

Nigeria's Tobi Amusan, who held the world record heading into the race, finished second with a season's best time of 12.23 seconds. European champion Nadine Visser completed the podium in third place, also recording a season's best of 12.34 seconds. Russell's record-breaking performance underscores her position as one of the world's elite hurdlers and highlights the competitive depth in the women's 100m hurdles event.
