We'll be back tomorrow with more action from Nanjing, China.

You'll be able to watch the morning session from 02:00 GMT on BBC iPlayer and the BBC Sport website and app.

And the evening session will be live on BBC Two from 10:30.

See you then!

On Saturday it's all about Great Britain's Molly Caudery, who will go in the women's pole vault final in the morning session.

If you want to watch that one, you'll have to set your alarm pretty early as it will be happening at around 02:10 GMT.

We'll also have the women's 400m final where Amber Anning will go for gold and Amy Hunt will hope to match Jeremiah Azu's achievement in the women's 60m.

Olympic pole vault champion Armand Duplantis is also in action on another busy day of action.

And there was a stunning silver for Ireland's O'Connor in the women's pentathlon.

Here's what's happened on an action-packed day one in Nanjing, China.

Georgia Hunter Bell qualified in top spot for the women's 1500m final on Sunday while compatriot Revee Walcott-Nolan missed out.

Neil Gourley qualified for the men's 1500m final along with Norwegian superstar Jakob Ingebrigsten while Adam Fogg missed out.

Amber Anning cruised through to the women's 400m final in top spot.

And as we've just seen, Jeremiah Azu won gold in the men's 60m to add a first global title to his European Indoor gold.

It's been quite a journey for Great Britain's Jeremiah Azu.

Within two weeks of his triumph at the European indoors, the 23-year-old announced himself as a world champion by equalling that personal best performance of 6.49 seconds.

It saw him cross the line one hundredth of a second ahead of Australian Lachlan Kennedy, who was initially shown as the winner on the big screen in Nanjing, China.

World Indoor gold has added a stunning conclusion to a whirlwind month for Azu, who celebrated the birth of his son just one week before claiming his first individual international title on the European stage.

It's quite a turnaround from being disqualified from the Olympic 100m in Paris last year.

More from Jeremiah Azu: "It's about the final and doing it when it matters. I'm glad I've got the ability to do that.

"The people around me inspire me in so many different ways. This one goes to Helen [James, his coach]. I wouldn't be here without her.

On the moment he realised he had won: "Compared to the Europeans I had more of a feeling I won this time but I didn't want to start celebrating! When I saw it was me I just exploded.

"I knew I could win it. I'm excited for the future. I said at the Europeans I want to take over the world. This is just the start of our journey.

"The plan is to keep on winning. I'm excited now. I want to get out there and race.

"The sky isn't the limit - there is way, way more than that. Let's see what the summer brings - I'm excited for it."

An emotional Jeremiah Azu, world indoor 60m champion, speaking to BBC Sport: "I was a bit emotional before the final with my coach. I think the last few years have been very difficult for me. This morning I was thinking about it and reflecting.

"It's so important to surround yourself with people that believe in you and that care about you. If I came last today, they would be the same. That is huge for me.

On moving back to Cardiff: "It's been huge. Family is everything to me. I sacrificed that for the last few years. You learn a lot about yourself off the track.

"I grew as a person and as an athlete. Being back with my family, having that support team around me, is huge. They allow me to believe in myself and that's something you can't teach.

"It's so important to success - in the formula to win, you need that belief. Anyone there could have won it and they allowed me to believe it was me. I ran my personal best. My team is amazing, truly."

You can't get much closer than that...

Jeremiah Azu crossed the line in 6.49 seconds.

Equalling his personal best. Lachlan Kennedy crossed the line in 6.50.

An emotional Azu is currently chatting with BBC Sport, full quotes to come.

Eloy Benitez stumbled early on in the race and fell over. The rest of the field did well to keep their composure with that distraction.

Ronnie Baker crossed the line clutching his hamstring.

A couple of the favourites wiped out there.

Jeremiah Azu won't mind, he's managed the whole day really well and has got his reward at the end.

It's too close to call!

Jeremiah Azu got off to a brilliant start but did he lose it at the end?

The year Jeremiah Azu had last year, with the massive disappointment at the Olympics where he was disqualified, to start the year on a golden high is really impressive and shows a lot about his mentality.

If he can get another medal here it is going to give him so much confidence going into the outdoor season.

Here we go then, Jeremiah Azu lines up in lane six. A confident wave to the camera and he looks ready to go.

And now to our final event of the day.

Great Britain's Jeremiah Azu goes in the men's 60m final.

He's ran confidently in the heats and semi-finals and is in great form having won European gold a couple of weeks ago.

Can he add a world title to that?

A brilliant run from Ireland's Kate O'Connor!

All she had to do was beat American Taliyah Brooks in a foot race to turn her bronze medal into silver and she's done just that.

Impressive stuff. Brooks takes the bronze.

Ireland's Kate O'Connor is sitting in fourth place as we approach the two-lap mark.

If she can beat American Taliyah Brooks in the race she can take the silver medal.

I think Kate O'Connor has got the edge. Judging by the way she ran the 800m at the European indoors, she ran so well.

I think she is capable of doing it.

Off we go then, the conclusion of the women's pentathlon.
