Lyon's Europa League quarter-final first leg with Besiktas was delayed by 45 minutes on Thursday night after fans ran onto the pitch to protect themselves from the throwing of firecrackers and projectiles.
When the match got under way, former Liverpool striker Ryan Babel put Besiktas ahead but moments after Corentin Tolisso's equaliser on 83 minutes, Jeremy Morel robbed Spanish goalkeeper Fabri in the area to tap into an empty net.
Lyon president Jean-Michel Aulas then came down to the pitch in an apparent attempt to defuse the situation.
