Russian and Polish football fans in Warsaw have clashed ahead of a Euro 2012 match between the two teams.
Thousands of Russian fans had been taking part in a march to mark their national day, but the march had to be halted after some missiles were thrown.
About 6,000 police are on duty to keep the rival fans apart.
