Great Britain's Josh Kerr speaking to BBC Sport after the men's 1500m semi-final: "It was very difficult to know what is what was going on around you at the end. You can always expect some dramatics in the semi-final of the World Championships!

"The way I ran was not the plan today. But the plan was to get through and I did."

Mondo Duplantis puts a finger to his mouth as he responds to the medal scrap going on around him with another effortless first-time clearance at six metres.

He is operating on an entirely different planet to his competitors.

Those world record expectations continue to grow, and grow, and grow.

Athletics' megastar means business tonight.

We talk so much about speed in this event.

Men at this level will be coming in at 9.4 to 9.6 metres per second. Then you have Armand Duplantis who is coming in at 10.4 metres per second.

They have to take that horizontal speed and transfer it into vertical height. It is about how efficiently you can transfer energy with no leakage.

We're onto six metres in the men's pole vault final after Emmanouil Karalis makes 5.95 on the third attempt.

The Greek clears 6m on the first attempt, before Sam Kendricks clips the bar.

Up steps Armand Duplantis.... masterclass. He sails over with ease, and then holds his fingers to his lips. Shushing his doubters? Surely he doesn't have any.

Next up it’s the men’s 3000m steeplechase final.

Soufiane El Bakkali is the favourite to take the title and cruised through his heat in 8:26.99. The Moroccan has won an Olympic or world gold medal in each of the past four years and is searching for a three-peat at the World Championships.

Ethiopian world record holder Lamecha Girma, a three-time world silver medallist, is also in the hunt but has only competed twice since suffering a horrific fall on the last lap of the Olympic final.

Kenyan teenager Edmund Serem, the reigning World U20 champion, won his heat ahead of Getnet Wale and Japan’s Ryuri Miuru.

Great Britain's Jake Wightman speaking to BBC Sport after the men's 1500m semi-final: "I got myself into some tough spots. I worked harder than I should have done at times.

"The last 200 metres felt good. Josh [Kerr] and I are both through so that is all that matters.

On the automatic qualifying: "It is not fair on the first semi-final. This is racing so it should be the top six and that is it."

Reynold Cheruiyot just about wins the second semi-final, as Olympic champion Cole Hocker is beaten on the sprint after leading for most of the race.

A photo finish is needed to sort of the rest, but it shows that Great Britain's Neil Gourley JUST sneaks into the top six by a thousandth of a second after finding himself dangerously boxed in. That was a close call.

We're likely to see some appeals go in, as Foster Malleck and Federico Riva finished over 36 seconds behind the rest after falling early in the race.

Drama in the second semi-final as two runners fall and are way behind!

Olympic champion Cole Hocker leads with 400 metres to go, with Great Britain's Neil Gourley looking a little boxed in.

American pole vaulter Sam Kendricks is sprinting on the track as if he's just won the gold medal!

A second-time clearance over 5.95m means an awful lot to the two-time world champion and it lifts him up to second, behind the so far perfect Armand Duplantis, as we reach the business end of the men's pole vault final.

Great scenes.

USA's Sam Kendrcks joins Armand Duplantis in clearing 5.95.

And Australias Kurtis Marschall is also clear with a new personal best.

But Greece's Emmanouil Karalis only has one more attempt at the height.

British pair Josh Kerr (3:35.53) and Jake Wightman (3:35.56) are through to the 1500m final, qualifying in second and third place in the first semi-final.

Kerr set the pace for the entire race before being pipped into first place by Niels Laros (Netherlands) in a tight bunch finish. Kerr was caught in a tumble after the finish line but was quickly back to his feet.

Wightman, who was content to run in the middle of the group until the final 200m, came through for third place, followed by Timothy Cheruiyot (Kenya), Andrew Coscoran (Ireland), and Samuel Pihlstrom (Sweden).

Three days in and Great Britain are still seeking their first medal success here in Tokyo.

Looking ahead, one of the first opportunities to end that wait could very well be Wednesday's men's 1500m final.

The medal fight in this competition was blown wide open in the heats, where Azeddine Habz and talented Kenyan teenager Phanuel Koech - the two fastest 1500m runners this year - and Norwegian star Jakob Ingebrigtsen all exited.

With their two world champions - 2023 winner Josh Kerr and 2022 gold medallist Jake Wightman - plus world indoor silver medallist Neil Gourley all still in contention, there's a real chance this is one event which could deliver.

Josh Kerr is really just controlling the pace.

You can see Laros trying to go around him but it is so hard. Wightman is trying to get himself out of trouble in the middle.

With two laps to go in the first semi-final, Britain's Josh Kerr and Sweden's Samuel Pihlstrom are setting the pace.

However, the group is still all together.

Josh Kerr is in really good shape. He believes in himself.

He strategically plans around this all year, he plans when he is going to race. He does everything he can to get himself onto that start line and give himself the best shot.

The action comes thick and fast - onto an event where Great Britain has high hopes.

With Jakob Ingebrigtsen suffering a surprise exit in the heats of the men's 1500m, the field has opened up.

Great Britain's Josh Kerr will be hoping to reach the final and emulate his success in Budapest two years ago, as will compatriots Jake Wightman, who won gold in Eugene three years ago, and Neil Gourley.

Others to keep tabs on are Olympic champion Cole Hocker, the Netherlands' Niels Laros, and Isaac Nader of Portugal.

Kerr and Wightman are in heat one, with Gourley in heat two.

Armand Duplantis takes the upper hand in the men's pole vault final!

So far the world champion and his closest challenger, Emmanouil Karalis of Greece, have avoided each other by sitting out every other height.

They now face each other at 5.95m, and Karalis has failed on his first attempt, as does Sam Kendricks.

Duplantis? Of course he makes it.

Advantage Mondo.

You expect these semi-finals to be electric.

Danielle Williams did not get out of the blocks very well and she normally does.

Devynne Charlton had a good run. It seemed beforehand that she was going to be vulnerable but she has found her way to the final.

No surprises in the third semi-final.

American Olympic champion Masai Russell (12.42 seconds) and Jamaican reigning world champion Danielle Williams (12.44 seconds) taking the top two.

Devynne Charlton, running a season's best, and Pia Skrzyszowska take the last two spots in the final as the fastest non-automatic qualifiers as Diamond League champion Ackera Nugent misses out.
