The gold medal in the men's 60m was won by Italy's Olympic 100m champion Lamont Marcell Jacobs over American Christian Coleman.
At Tokyo 2020, Jacobs beat Coleman in 6.41 seconds.
He is the first reigning Olympic 100m champion to win an indoor 60m title.
Marvin Bracy ran 6.44 seconds to take the bronze medal.
Adam Thomas finished fifth in a time of 6.60 seconds.
Jacobs set a new European record with his winning time, which was eventually confirmed after the athletes waited for the official results to appear.
I am so tired but I am so happy, it is fantastic after two Olympic golds and the 4x 100m relay. I can't wait to go outside and run.
He said that his competitors are great sprinters. I am happy to compete with them. We will try to run fast again when I see them in the outdoor season.
Coleman wanted to become the second man to win back-to-back world indoor 60m titles.
The American was able to compete in Serbia after his two-year ban for missing three drug tests was reduced by six months.
I feel good. It was the best season of the year. I had a good race. Coleman, the reigning 100m world champion outdoors, said he was excited about the outdoors.
I feel like I have something to prove to myself. My talent speaks for itself and I think highly of myself. I want to be the best. I will keep working.
The wait for a medal continued for the British, as they had to withdraw from the 800m heats with a quad injury.
The 20-year-old was a strong medal favourite, having won Olympic silver in the discipline in Tokyo last year, and had also been due to compete in the 4x400m relay.
It was upsetting for me because I had never had to pull out of a race before. It is about looking at the bigger picture.
