NATIONS - FIFA: We have zero tolerance against such behaviour
In a statement, FIFA said it will investigate accusations of disruption at Wembley, where Hungary supporters fought with police until riot police restored order, as well as Poland's 1-0 triumph in Albania, which was delayed for 20 minutes in Tirana owing to items thrown at Polish players.
The governing body of international football announced in a statement:
"FIFA strongly condemns the incidents at England v Hungary and Albania v Poland and would like to state that its position remains firm and resolute in rejecting any form of violence as well as any form of discrimination or abuse.
"FIFA has a very clear zero-tolerance stance against such abhorrent behaviour in football."
It wasn't the first time in recent months that Hungary fans were in the center of a riot.
Racist shouts targeted Raheem Sterling and Jude Bellingham during England's 4-0 win in Budapest in September.
Towards the Puskas Arena, missiles were also launched at England's players.
Following the racist behavior, Hungary was sentenced to play two home FIFA competition matches behind closed doors, one of which was suspended for two years.
