Workers are photographed at the National Stadium in Warsaw, Poland, Friday, Sept. 9, 2011. The opening game of the Euro 2012 soccer championships will take place on the National Stadium in Warsaw. UEFA says it has concerns about safety in the eight newly built or reconstructed stadiums to be used for next year's European Championship in Poland and Ukraine. UEFA Head of Stadium and Security Marc Timmer told The Associated Press on Thursday that European football's ruling body is closely monitoring ongoing construction works "to make sure that all minimum standards are met." "At every venue, with no exception, there have been made many changes on our request," said Timmer, adding that this was still a major concern as "until a venue is really commissioned, you never know what's going to happen. They might make changes." (AP Photo/Czarek Sokolowski) less
