UEFA has begun disciplinary action against the Hungarian football federation for crowd disturbances inside the stadium in Marseille in their Euro 2016 match against Iceland.
European football's governing body also opened proceedings Sunday against the Portuguese federation after a fan invaded the pitch in Paris and took a photo with Cristiano Ronaldo at the end of the game against Austria.
Further disciplinary proceedings were opened against Belgium's federation over incidents in the match against Ireland.
UEFA says its disciplinary panel will rule on crowd disturbances, the throwing of objects and the setting off of fireworks by Hungary fans in Saturday's match against Iceland which finished 1-1.
Police were deployed to stand in front of a section housing Hungary fans at the Stade Velodrome after they clashed with stewards before the game.
The case will be decided by the UEFA control, ethics and disciplinary Body on Tuesday.
The charge against the Belgian federation relates to the setting off of fireworks and the throwing of objects in the match in Bordeaux on Saturday.
No date has been set for the disciplinary panel to meet on sanctions for the Belgian and Portuguese federations.
