- Poland's sports minister says the violence appalls her, but it won't spoil the event
- UEFA imposes a suspended penalty on Russia over disorder by its fans Friday
- More than 150 Poles and more than 20 Russians are among 184 people detained by police
- Poland is co-hosting the Euro 2012 soccer tournament with Ukraine
European football's governing body took a tough line against soccer-related disorder Wednesday, as it imposed a penalty on Russia for "improper conduct" by its fans at the Euro 2012 tournament.
The ruling by UEFA relates to the opening game of the tournament in Wroclaw, Poland, on Friday.
Its officials are still considering what action to take over allegations of racist abuse by Russian fans at the same game, and violence before and after a Euro 2012 game in Warsaw on Tuesday.
Police detained 184 people after clashes broke out in the Polish capital before and after the Poland-Russia game, which ended in a 1-1 draw.
Interior Minister Jacek Cichocki told reporters that more arrests could come. "Police officers continue to watch recordings from CCTV and police cameras to identify other hooligans who disturbed public order," he said.
The suspended six-point deduction imposed on Russia by UEFA will apply to the qualifying campaign for the Euro 2016 tournament, rather than the current one.
