The 23-year-old's shock achievement was fervently acclaimed by home fans on a night which had contained outstanding but expected victories from Femke Bol of The Netherlands and Norway's Karsten Warholm in the 400m and Britain's Laura Muir in the women's 1500m.

And there was a further unexpected win at the end of the programme as Italy’s 23-year-old Samuele Ceccarelli won the men's 60m title ahead of his compatriot and defending champion Marcell Jacobs, the Tokyo 2020 100m gold medallist.

After running through on her last effort, already assured of victory after Italy’s eventual silver medallist had failed to improve upon her best of 14.20m - to huge cheers - Danışmaz lay back, hands over her face, shoulders heaving with emotion - and surrounded by photographers.

Collecting herself, she wandered over to the stand to receive delighted hugs and her own happy version of the flag that has flown at half-mast throughout this city following the awful loss of life from the earthquakes on February 6.

"We are going through a very tough time and if people are happy because of my medal and they are healing their wounds because of the medals, that makes me very happy and proud," said Danışmaz, whose decisive effort came in the first round.

"The spectators were so great today and if I make them smile, that is very good.

"I am very happy to win this medal for Turkey here today in front of the Turkish people.

"I am so happy that I am not alone in this - I have so many foreign friends who sent me messages and supported me so I am happy we are not alone."

Portugal's Olympic silver medallist Patricia Mamona took bronze with 14.16m.

Ceccarelli, who had qualified fastest for the men's 60m final in 6.47, was a hundredth of a second slower in the second race, but it was enough to defeat Jacobs, who appeared to be in some discomfort with his hamstring and clocked 6.50, with bronze going to Henrik Larsson in a Swedish record of 6.53.

Bol and Warholm fulfilled widespread predictions of victory over 400m as both 400m hurdles specialists sought to sharpen up on the flat before the challenges of a season that will climax with the World Athletics Championships in Budapest - but the Norwegian Olympic champion and world record holder had to battle for his gold.

While the Dutch world record holder sped away from all opposition in the women’s final to retain her title in 49.85, her third sub-50sec time of the season, Warholm came under such heavy pressure from Belgium’s fast-finishing Julien Watrin that his desperate lunge for the line caused him to hit the deck heavily.

By the time he had picked himself up and dusted himself down, though, there was reassuring digital evidence that he had won in 45.35.

Watrin - another 400m hurdler who finished sixth in last year's world final - clocked a national record of 45.44 for silver, with a third 400m specialist hurdler, Sweden's Carl Bengtstrom, taking bronze in 45.77 ahead of Spain's defending champion Oscar Husillos, who recorded 46.24.

"I was stupid fast today I think," said Warholm.

"I do not know if you saw it but I felt lactic acid in the last 100 so I had to fight all the way through.

"I was just fighting my ass off to save myself and I am just very happy it was gold today."

It was always going to be a stretch for Bol to break her 400m personal best given that it was a world record of 49.26 that eclipsed the oldest track and field mark in the book, 49.59, set by Czech runner Jarmila Kratochvilova in 1982.

But she produced her third sub-50sec effort of the year, with her compatriot Lieke Klaver second in 50.57 and Poland's Anna Kielbasinska taking bronze in 51.25 - completing a hat-trick for athletes coached in Papendal by Laurent Meuwly.

"I have multiple European titles, but the world title is still missing," said Bol.

"The world record is step one.

"Coming to Istanbul with a world record, I could feel that everybody wanted me to go even faster and expected that I could 'easily' run a world record again.

"Unfortunately, it is harder than it might look like!"

Muir, 29, secured a third consecutive 1500m title in this competition with an utterly composed performance that saw her overtake Romania’s early leader Claudia Boboceau with just over a lap to go before crossing in 4:03.40, with ample time to raise her right arm in the air before the line.

The Tokyo 2020 silver medallist had won the 1500m and 3000m double in Belgrade 2017 and on home soil in Glasgow in 2019, but she decided to focus on the shorter event here and her decision was vindicated.

Wilma Murto, who twice broke the Finnish record to win the European outdoor women's pole vault title in Munich last year with a best of 4.85m, set an indoor national record of 4.80m to take gold ahead of Slovenia's Tina Šutej on 4.75m and Czech vaulter Amálie Švábíková on 4.70m.
