Next up, it's Ireland's Kate O'Connor in the women's pentathlon.

She will line up for the 800m - the final event - in third place in the standings with 3838 points, 178 points ahead of fourth-placed US athlete Timara Chapman.

At the European Indoor Championships, O'Connor clinched the bronze medal by winning the 800m. Can she produce another moment of magic?

Britain's Adam Fogg speaking on BBC Two after missing out on the men's 1500m final: "To be honest I couldn't have given it anything more. I think at the Euros I didn't quite have it, today I really wanted to get through. I was in a great spot, it was really slow, I thought it would be cagey so I would go from far out. I just was running all-out, got overtaken and had nothing.

"It is pretty embarrassing to be honest getting to this stage, ready to do alright and then it not going well at all.

"I felt like I had been running very slowly and I knew I could close quickly but I didn't have it at the moment. I'm not quite there. I'm making progress, I've come a long way, but the bar on the world stage keeps getting raised.

"I need to keep working hard. I think I'm capable of getting to the final but then I'm wiped out in the heats. I gave it all I had but it wasn't enough."

Norwegian superstar Jakob Ingebrigsten and Great Britain's Neil Gourley qualified for the 1500m final earlier.

That final will take place on Sunday.

American duo Brian Faust and Jacory Patterson progress to the men's 400m final with Brazil's Matheus Lima joining them.

A very strong American contingent in that final.

Here's how Jeremiah Azu made it through to the men's 60m final. That will be our final event of the day coming up at around 13:25 GMT.

The men's 400m semi-finals have just got under way and American Christopher Bailey, Canada's Christopher Morales-Williams and Poland's Attila Molnar have made it through to the final.

After the next semi-final we'll have the conclusion of the women's pentathlon where Ireland's Kate O'Connor will go for a medal in the 800m.

And then it will be the men's 60m final where Great Britain's Jeremiah Azu will go for gold.

Great Britain's Amber Anning speaking on BBC Two after qualifying comfortably for the women's 400m final: "It felt good, it felt smooth. I wanted to run 50 point [seconds] in the heats and get that automatic qualification for the final.

"Today was about getting a clean race. Tomorrow I'm excited to have another opportunity to get on the podium.

"I am feeling good, feeling strong and I'm excited to get back, recover and get ready for the final."

Amber Anning comfortably the quickest of the six qualifiers for the 400m final.

That's coming in tomorrow's evening session.

Amber Anning, of all the major contenders, certainly looks the strongest.

Very impressive run from Amber Anning and she takes top spot in 50.8 seconds.

A statement run from the Briton.

Amber Anning just needs to concentrate here. She has done this so many times. You want this to be a robotic performance.

Amber Anning leads after the first lap.

Concentrating hard on keeping in her lane.

Third and final women's 400m heat coming up.

Great Britain's Amber Anning is in contention here.

Five ran the second heat of the 400m.

American Alexis Holmes cruises through in top spot and Poland's Justyna Swiety-Ersetic made a late surge to take second place.

Jamaica's Leah Anderson ran into trouble in the final 100m and fell just after crossing the line just from sheer tired legs.

Great Britain's Amber Anning up next.

Only three ran in the first heat. And the top two qualified.

Norway's Henriette Jaeger and Chile's Martina Weil qualify for the final with Burkino Faso's Sita Sibiri missing out by quite a distance.

Up next it's the women's 400m heats.

Great Britain's Amber Anning will hope to challenge in another major final following the disappointment of her disqualification at the European Indoors for a lane infringement.

Jeremiah Azu has put himself in a great position.

You can't make massive changes to your technique or race plan, you just need to recover and be focused on how you execute that final.

That final is going to be fascinating. Jeremiah Azu will be in there, among so many contenders for the medals.

And in the third and final heat, Puerto Rico's Eloy Benitez and South Africa's Akani Simbine are through to the men's 60m final.

Benitez came through in a time of 6.52 seconds.
