Stadium stunned as Hassan fallspublished at 20:36 British Summer Time 19 August 2023
Harry Poole
BBC Sport in BudapestEveryone in the stadium is stunned.
There are people with their hands on their head in front of me in the press seats. Wow.
The atmosphere was electric on that final lap as Sifan Hassan looked to have taken charge but what drama at the end!
Was there contact? It's difficult to tell but Hassan's reaction suggests there wasn't much in it.

Women's 10,000m final
There was a little bump between Sifan Hassan and winner Gudaf Tsegay but I'm not sure if there's enough for any sort of dispute.
From the lead, with 25m to go, Sifan Hassan ended up flat on the track.
In the end it's a one, two, three for Ethiopia.

We need to see a replay.
Was Sifan Hassan tripped? There's blood trickling from her knee.
She's certainly not complaining.

Siffan Hassan had it in her hands but stumbled in the closing moments. She ends up with nothing.

The lead group is getting smaller but Jess Warner-Judd is hanging in there for Great Britain.
Sifan Hassan has picked up a sponge from the sidelines and is dabbing herself down as she runs.
Harry, our man in Budapest, can confirm it's warm out there.

Letesenbet Gidey, the world record holder and other great Ethiopian in this final, takes on the role at the front now.
Still, Sifan Hassan is unmoved towards the back.

Sifan Hassan darts up a space or two as the race reaches the 6,000m point.
Meanwhile, Ethiopia's Gudaf Tsegay, the world champion over 5000m, takes on the pace at the front.
She's one of the main contenders.

Britain's Jessica Warner-Judd is bobbing around but still sits third from the front in this women's 10,000m final.
The main contenders, meanwhile, are all tucked away in the middle.
It's still not a particularly quick pace so could come down to a serious sprint for gold.

Women's 10,000m final
These 10,000m runners are strung out in a long line now as the pace increases. For a moment Sifan Hassan looks to be getting dropped off the back but she keeps her composure to remain in touch.
Hassan often likes to toy with us in these races. She looked done at times on the roads of London in April and still won.
Ethiopians Letesenbet Gidey and Gudaf Tsegay are also near the back.
