Polish news anchor Piotr Krasko has publicly apologized for his station mistakenly showing the Soviet flag during a report about the Polish-Russian soccer match at the Euro 2012 tournament.
The graphic of the flag with the hammer and sickle appeared during a report on a news show on June 13 on TVP1, one day after Polish and Russian fans clashed in Warsaw.
Krasko said the Soviet flag graphic was prepared for a report about previous matches between the Soviet Union and Poland.
Krasko said it was an "unintentional mistake and at the worst possible moment."
Russia has been using a tri-colored flag for more than 20 years.
