Crowd disorder inside the stadium has delayed the kickoff in the Lyon-Besiktas Europa League quarterfinal first-leg game.
The incidents followed fighting among rival French and Turkish fans earlier Thursday in Lyon.
Ahead of the scheduled 9:05 p.m. (1905 GMT) kickoff, fans spilled on to the field for their own safety as fireworks were set off and missiles thrown from a section housing Besiktas supporters, the AP reported.
Lyon president Jean-Michel Aulas was among the officials on the pitch trying to restore calm.
