Violence At Euro 2012
Russian soccer fans clashed with police and Poland supporters in separate incidents in Warsaw shortly before the two teams were to meet in an emotionally charged match at Euro 2012.
Police said 10 people were injured; seven Poles, two Russians and one German. In what appeared to be the most violent incident, Polish football hooligans were seen attacking Russians.
The two countries share a difficult history, including decades of control by Moscow over Poland during the Cold War.
