Here are some of the videos that have surfaced from this morning's clashes between Russian and Polish soccer fans, before their teams' match later today at Euro 2012. According to one (biased) account, a Russian fan march was set upon by Polish supporters, and broken up by police firing tear gas and nonlethal rounds. Those rounds can be heard and seen in the videos below.

Russian fans, you remember, already started shit inside a stadium over the weekend, attacking stewards and garnering UEFA's first official condemnation of the tournament.
