More joy for the home fans, as Junxi Liu wins heat two to become the second Chinese man to reach the 60m hurdles final.

Lorenzo Simonelli records a season-best to finish second and also progress. Jakub Szymanski meanwhile faces a nervous wait - he's currently the second-fastest of the lucky losers, so needs a slow final heat to progress.

Amber Anning looked in fantastic form at the European indoors. She looks physically in fantastic condition.

I really hope this will be the time for her to claim some individual glory.

Yesterday, Amber Anning underlined her gold medal credentials with a statement 400m qualification.

Olympic finalist Anning set the fastest time of the women's 400m heats, clocking 50.79 secs in setting up her shot at a first individual international medal.

The Brit goes in the final at 12.44 GMT.

An early potential upset in the first semi-final, as Poland's Jakub Szymanski - widely regarded as one of Grant Holloway's most likely challengers - has only finished third in his heat.

Szymanski led over the final hurdle, but caught it and stumbled into the lane next door.

Demario Prince of Jamaica and China's Weibo Qin take the automatic spots in the final by finishing top two in their heat. Szymanski must wait and see if he gets one of the two places reserved for the other fastest qualifiers.

Fair to say that Britain's Jeremiah Azu is loving life after winning gold yesterday...

Next up on the track is the semi-finals of the 60m hurdles - three men's heats followed by the women's event.

In the men's event, American Grant Holloway is the one to look out for. He has won 91 consecutive races in this event indoors. No-one has beaten him since 2014.

Back on the field... six men remain in the pole vault final, with the bar now set at 5.90m. Mondo Duplantis will jump this height - and he makes it with ease.

In the women's triple jump, that monster opening jump from Leyanis Perez Hernandez may have already settled matters. Her mark of 14.93m is nearly 0.4m better than the rest of the field.

Jakob Ingebrigtsen really hates losing and that is why that 1500m title tomorrow will be the one that really means a lot to him.

You can never doubt just how deep this man can dig.

There was not a hint of panic when he was being forced to run wide into those final 200m. He was able to settle back and find enough in the final straight.

Jakob Ingebrigtsen had to run a season-best of 7:46.09 to take that gold. He was pushed all the way.

A really good race, won by one of the world's best.

Berihu Aregawi of Ethiopia now takes the lead! He leads Ingebrigtsen as they approach the final lap.

This will be close...

Jakob Ingebrigtsen was a bit boxed in there, so he moved to the outside of the pack. Will he attack now?

Three laps to go.

Jakob Ingebrigtsen has allowed the field to swallow him up for now. Expect him to attack again shortly.

The new leader is Cornelius Kemboi of Kenya.

Now here's something interesting - Ireland's Andrew Coscoran has made an early move for the front.

It's a long way to the finish - 1200m to go - but it seems to have given the field the hurry up as the pace increases.

It's Ingebrigtsen and two of the Ethiopians - Getnet Wale and Biniam Mehary - up at the front.

They are approaching the halfway mark.

It is a slow start to this race - almost walking pace for these elite athletes.

Jakob Ingebrigtsen usually sits at the back in these big races, but he's decided to assert his authority to move up near the front.

It is a very congested track in Nanjing, to the extent that the 12 men have to begin with a staggered start.

But they are under way safely in this 15-lap race.

Now on track, we have the contenders in the men's 3,000m final.

Jakob Ingebrigtsen, two-time Olympic champion, is the man to watch. He has never won a world indoor title, will that change in a few minutes?

While that 3,000m final took place on track, the field events continued apace.

We are down to the final seven athletes in the men's pole vault - including Mondo Duplantis, who has passed at 5.80m.

Johannes Erm has cleared 1.92m in the high jump discipline of the heptathlon, although current leader Sander Skotheim is yet to jump.

And in the early stages of the women's triple jump, Leyanis Perez Hernandez has put down a real marker with her first jump - 14.93m, a world leading distance for this year.
