NYON, Switzerland — UEFA has charged Legia Warsaw over crowd violence and racist behavior at the club’s first Champions League game in 20 years.

Fans clashed with stadium security staff, and anti-discrimination monitors reported anti-Semitic abuse during a 6-0 home loss against Borussia Dortmund on Wednesday.

UEFA said Friday its disciplinary panel will judge the case on Sept. 28. The Polish champion and Dortmund also face charges of fans throwing objects and lighting fireworks.

Legia was returning to the elite Champions League stage after reaching the quarterfinals in 1996.

The club has faced regular UEFA sanctions in recent years, including for racist incidents and fans displaying offensive banners.
