Heartbreak for Yared Nuguse, who fades to seventh in the end, and that is one of the major medal contenders out of the men's 1500m in Tokyo - an event in which Great Britain will have two world champions in Josh Kerr and Jake Wightman.

Talented Dutch 20-year-old Niels Laros displays his devastating finishing speed to capture the Diamond League trophy and prize money in a national record three minutes 29.20 seconds. He will be a big threat next month.

Italy's Andy Diaz won the men's triple jump with a jump of 17.56m.

Portugal's Pedro Pichardo (17.47m) and Algeria's Yasser Mohammed Triki (17.42m) had set the pace with season's best jumps in round one before Diaz snatched the lead in the fourth round.

Diaz previously won the Diamond League crown in 2022 (representing Cuba) and 2023 and claimed bronze at the 2024 Olympics.

Over to the men's 1500m now.

And this is an absolutely huge race for American Yared Nuguse, with the Olympic bronze medallist's hopes of competing at the World Championships resting on victory here after he failed to qualify via the US trials.

The Diamond League winners receive a wildcard to the championships. Away we go...

Oh no, that is agonising for Jessica Hull!

The Australian's legs have completely gone as she struggles to hold on down the home straight, before she is pipped to victory on the line by Kenya's Nelly Chepchirchir.

Chepchirchir wins it in three minutes 56.99 seconds as Hull drops to the ground, utterly exhausted after finishing second in 3:57.02.

Ireland's Sarah Healy places eighth in 3:59.90.

Cuba’s Leyanis Perez has won the women’s triple jump title for the second year in a row.

The world indoor champion jumped 14.91m in Zurich – just two centimetres short of her season best.

Her compatriots Liadagmis Povea and Davisleydi Velazco completed a Cuban 1-2-3, with jumps of 14.72m and 14.65m respectively.

American Cordell Tinch claims the men's 110m hurdles title, tying the meeting record in 12.92 seconds in Zurich.

Next up on the track we have back-to-back 1500m finals, with the women up first.

Olympic champion Hamish Kerr has seen off Ukraine’s Oleh Doroshchuk to win the men’s high jump title.

The New Zealander cleared 2.32m at the first attempt, prompting Doroshchuk (2.30m), who missed his first attempt at that height, to push the bar up to 2.34m. However, neither athlete produced a successful jump.

USA’s JuVaughn Harrison finished third, posting a best jump of 2.25m.

Can you believe it, the World Athletics Championships are little over two weeks away.

This is the final night of major competition on the calendar before then, with athletes heading off to their various pre-champs training camps to finalise their preparations.

Don't forget, you'll be able to follow coverage of the worlds across the BBC from 13-21 September as the sport's biggest names again go head-to-head in pursuit of global titles.

Jamaica's Ackera Nugent pulls away in the second half of the race to take victory in the women's 100m hurdles final in 12.30 seconds.

Switzerland's Ditaji Kambundji comes second in 12.40, equalling the national record on home soil, but that is a commanding win for Nugent.

It's over to the hurdles and steeples for a little while now on the track.

Next up is the women's 110m hurdles, before the men's 3,000m steeplechase and the men's 110m hurdles.

Ethiopian 19-year-old Aleshign Baweke produces an excellent finish to take the Diamond League title in the women's 3,000m.

The athletes decided against pursuing the pacemaker from the start and the time is irrelevant for Baweke, who clocks eight minutes 40.56 seconds.

Britain's Hannah Nuttall finishes eighth in 8:44.74.

Lithuania’s Mykolas Alekna is the men’s discus champion, producing a winning throw of 68.89m.

The 22-year-old, who led from the first round, is a former European champion and won a silver medal at the 2024 Olympics.

Reigning European champion Kristjan Ceh (Slovenia) came second with a throw of 67.18m and Jamaica's Olympic champion Roje Stona was third (67.06m).

Defending world champion Daniel Stahl could only finish fifth (66.47m).

Amber Anning, speaking to BBC World Service Sport after her fifth-place finish in the women's 400m: “It’s a season’s best, I’m moving in the right direction.

“I definitely wanted more, I think I’m in better shape, but it’s the fastest I’ve done all season and it bodes well for setting me up for Tokyo.

“Training’s been really great, really consistent, just trying to get that rhythm and have the confidence to go for it.

“I’ll take that, it was against a really strong field. I’m grateful to be here.”

Hannah Nuttall is preparing for her first major outdoor championships in Tokyo.

The 28-year-old retained her British title this season and lowered her 5,000m personal best to 14:39.48 at the London Diamond League in July.

She also improved her 3,000m best to 8:33.82 in June - the event in which she runs this evening as she begins to put the final touches on her preparations.

That final has just got under way.

American Jacory Patterson runs a personal best 43.85 seconds to further assert himself as a gold medal contender in the 400m in Tokyo.

The 25-year-old dominates the final in the second-fastest time in the world this year.

He set a personal best earlier this year - and the then-fastest time in the world - despite balancing his training with an overnight job which he was able to leave earlier this summer.

The Netherlands’ Jorinde van Klinken pipped former world champion Yaime Perez (Cuba, 66.08m) into second place, throwing a season's best 67.15m in the final round.
