PARIS -- The French football federation has opened disciplinary proceedings against Paris Saint-Germain and Marseille following incidents during the French Cup final that raised major concerns only a few weeks before the country hosts the European Championship.

Despite a two-meter high security wall surrounding the Stade de France and triple security checks, supporters smuggled flares into the venue in the northern Paris suburb of Saint-Denis and ignited fires in the stands.

Fans also complained about severe overcrowding at the security check points.

PSG won the game 4-2.

A statement from the French Interior Ministry said "it has been decided to correct dysfunction without delay in order to guarantee the fluidity of supporters entering sporting venues and to strengthen security checks by private companies and secure stadium exits."
