Riot police in the Polish capital used truncheons and rubber bullets on Sunday, Nov 11, to break up a crowd of right-wing extremists who pelted them with firecrackers and lumps of concrete at a parade to mark the national holiday, according to Reuters.

It was the second year independence day celebrations have degenerated into violence, underlining the gulf between the government and hardline nationalists who think liberal values imported from Europe are ruining Poland's Catholic traditions.

Police said that 132 people were detained following the violence, which took place in central Warsaw. Five policemen sustained injuries that needed hospital treatment.

The day started with thousands of police in riot gear lining the streets trying to stop trouble erupting between right-wing groups, left-wing radicals, and government supporters -- all holding their own independence day parades to push their competing visions of what sort of country Poland should be. Poland, the biggest economy in eastern Europe, is experiencing a period of peace and prosperity unusual for a country with such a turbulent history, Reuters says.

Violence flared as demonstrators gathered for a right-wing rally in the shadow of the Palace of Culture and Science, a neo-gothic, Soviet-era skyscraper in the city center.

Young men with their faces covered by scarves chanted nationalist slogans and railed against supposed Jewish conspiracies.

Not all were there because of their political convictions. Large numbers appeared to be soccer hooligans who were attracted by the prospect of a fight.

Some of the crowd threw firecrackers and projectiles at police in riot gear who had cordoned off the area. They also ran to a nearby construction site and tore off lumps of concrete to use as missiles.
