French sports minister Thierry Braillard labelled the violent scenes that marred Sunday's Ligue 1 match between Marseille and Lyon as "unacceptable".
Mathieu Valbuena's return to his former club with Lyon provided a fiery backdrop to the fixture and the playmaker found himself at the centre of the action as tensions reached boiling point.
Lyon led through Alexandre Lacazette's 25th-minute penalty and they also had a one-man advantage when Roman Alessandrini was sent off for a rash tackle on the impressive Valbuena.
Play was suspended for 23 minutes during the second half as Valbuena was pelted by objects as he prepared to take a corner – an assault that saw six stadium stewards come to the assistance of the player.
"We are, after all, months from a tremendous event which is the organisation of the European football championship and I really call for everyone to assess what happened," Braillard told French radio RTL.
"This is unacceptable and I think we really need to have much firmer controls.
"Marseille is a footballing city. The Marseille public is known to be a great public. I think there are security measures that must be respected and we can't see glass bottles like that in the stands.
"Where are we going? Imagine that a bottle had struck a player. What situation would we be in today? It's unacceptable and I think that we really need to tighten up controls."
LFP president Frederic Thiriez has called an emergency meeting at the organisation's Paris headquarters after a weekend that also saw clashes at the match between Bastia and Nice, while Paris Saint-Germain fans were involved in disturbances after their 1-1 draw at Reims.
