Russian football fans were marching through Warsaw when they were suddenly attacked by Polish fans. Around eleven people were injured and taken to hospital.
Following the recent Digital Journal report on Russian fans attacking stewards at the Euro 2012, more violence has now occurred.
Russian and Polish football fans clashed outside the National Stadium in Warsaw yesterday with around 11 people injured.
Police were forced to fire warning shots and to use a water cannon to break up the fighting. 100 arrests were made. Police also used tear gas and rubber bullets against the hooligans, who in turn threw stones and firebombs back at them.
Apparently it all started when around 5,500 Russians were marching through the Polish capital and were attacked by a mob of Polish youths. A mob of around 50 Polish fans also attacked a café in central Warsaw, where Russian fans had gathered prior to the match.
The Polish fans were reportedly wearing masks and threw smoke grenades and stones at the café. The Russians apparently fought back and the attackers retreated. One Russian fan suffered serious head injuries.
Initial reports stated that at least eleven people were injured and were taken to a nearby hospital for treatment to head injuries. At least one of the injured was apparently a Polish national.
The Polish State Police Office gave a statement that, "A hundred hooligans, both Russian and Polish, attempted to provoke a conflict. Police prevented that. Fifty-six people have been detained so far." The number of arrests later increased to approximately 100.
"We are aware of ten casualties: two Russians, one German and the rest are Polish nationals," added the office.
The march by the Russian fans was to celebrate Russia Day, which occurs on June 12, and had been sanctioned by authorities in the city.
