The Russian foreign ministry on Tuesday summoned the Polish ambassador after ultra-nationalist rioters in Warsaw set alight cars and overturned a guard's booth outside the Russian embassy.
"The Polish ambassador Wojciech Zajaczkowski is being summoned to the foreign ministry over yesterday's excesses against the Russian embassy in Warsaw," the ministry said in a statement on its website.
The spokesman for Poland's foreign ministry Marcin Wojciechowski on Monday wrote on Twitter, saying: "There is no justification for hooliganism."
Around 50,000 people surged through Warsaw on Monday in a march organised by far-right groups on Poland's independence day. Four police officers were hospitalised after demonstrators threw stones and bottles.
