Police officers as Lyon fans invade the pitch and fans clash in the stands
Pictures and videos have emerged on Twitter of fans clashing in the stands before pouring onto the pitch.
The Europa League quarter-final first leg was due to kick off at 8.05pm although that is now set to be pushed back.
“Projectiles and Fireworks launched from the top of the stands require supporters to seek refuge on the lawn,” Lyon tweeted.
