The Serbian Football Association has been charged by Uefa after objects were allegedly thrown during Serbia's Euro 2024 match against England.
Police said eight people had been temporarily detained following a brawl between England and Serbia fans before the game in Gelsenkirchen, Germany.
The Uefa charges include "transmitting a provocative message unfit for a sports event".
Earlier, the Kosovo Football Federation said it had made a complaint to Uefa about the "display of flags, slogans and chants by Serbian fans", which it said contained "political and racist messages against Kosovo".
European football's governing body said: "The Uefa Control, Ethics and Disciplinary Body (CEDB) will decide on the matter in due course.
"Furthermore, a Uefa Ethics and Disciplinary Inspector will conduct a disciplinary investigation regarding alleged discriminatory behaviour."
England won the Group C opener 1-0 thanks to Jude Bellingham's 13th-minute header.
