UEFA have condemned the violence that marred Poland's European Championship match with Russia - but it is unclear whether either team will face sanction.
Beyond issuing their own statement on Wednesday afternoon, European football's governing body was unavailable for comment about Tuesday night's events in Warsaw that saw 184 people arrested and, according to reports, at least 24 injured.
Trouble flared after a march by thousands of Russia supporters came under attack by masked hooligans.
Visiting fans inside the stadium also unfurled a giant banner that read, 'This is Russia', something that could be seen as a taunt about the decades of Moscow control over Poland during the Cold War.
UEFA said in a statement: "UEFA condemns the isolated incidents that occurred yesterday in Warsaw prior to and after the Poland-Russia match, when some groups of known troublemakers pelted the police with missiles and attacked fans irrespective of the team they were supporting.
"Those arrested and charged will have to be dealt with by the relevant authorities.
"UEFA's philosophy is to create a welcoming environment coupled with a low-profile approach to policing. The focus should be on facilitating the enjoyment of the matches by genuine football fans and isolating the tiny percentage of troublemakers.
"UEFA is in a constant dialogue with the public authorities in order to achieve this aim.
"UEFA is determined that the overwhelmingly peaceful and festive atmosphere that has so far pervaded at UEFA Euro 2012 will be continued right up to and including the final in Kiev on Sunday July 1."
Police are understood to have deployed water cannon and rubber bullets as part of their response to the trouble which occurred before and after the 1-1 draw.
A Warsaw police spokesperson said: "We are still monitoring the situation and trying to identify the supporters involved. The operation is not over from our side as we continue in our attempts to catch those who are causing trouble."
