UEFA has condemned clashes between rival supporters at the highly charged match between co-hosts Poland and old rivals Russia in Warsaw.
"UEFA condemns the isolated incidents that occurred yesterday (Tuesday)... when some groups of known troublemakers pelted the police with missiles and attacked fans irrespective of the team they were supporting," it said in an emailed statement.
"Those arrested and charged will have to be dealt with by the relevant authorities."
Police said they had arrested 157 Poles and 24 Russians in the violence, which saw riot squad officers use water cannon and fire tear gas and rubber bullets to disperse marauding fans.
