UEFA has charged the Hungarian, Belgian and Portuguese football associations for fan disorder at Euro 2016.
UEFA says its disciplinary panel will consider charges against Hungary of "crowd disturbances", throwing objects and setting off fireworks.
Fans clashed with stewards and some police before Saturday's Group F game with Iceland in Marseille when trying to climb a fence to enter a section behind one goal.
Riot police then formed in lines in front of a section of Hungary fans, in the same end of the Stade Velodrome where Russians attacked England fans a week earlier.
Hungary fans then lit or threw flares or firecrackers during the national anthems, when Iceland were awarded a penalty kick, and after their team scored a late goal in a 1-1 draw.
The Belgian FA has been charged after a section of their fans set off fireworks and threw objects during the team's 3-0 Group E victory over the Republic of Ireland in Bordeaux on Saturday.
And the Portuguese are in trouble over a pitch invasion by a supporter during their 0-0 draw with Austria at the Parc des Princes in Paris.
