In Sweden, counter-demonstrators rioted again on Easter Sunday after a meeting of the ultra-right group Stram Kurs (Strammer Course).
In the city of Norrköpping in the south of the country, the police said they fired warning shots.
Three people were injured, the broadcaster SVT reported in the evening.
There were also riots in Linköping, with more than 25 arrests in total.
The police said they were attacked themselves.
In Malmö in the south of the country, according to the police, a bus, a car and garbage cans were set on fire during the night.
Several reports of vandalism were reported.
The protests were triggered by a meeting of the anti-Islamic and anti-immigrant group Stram Kurs led by politician and lawyer Rasmus Paludan.
This is currently moving through various Swedish cities and holding meetings there, at which one Koran is to be burned at a time.
There have already been clashes between the police and counter-demonstrators in several Swedish cities.
Stones thrown at the police
Stram Kurs's rally on Saturday was moved from the originally planned Landskrona to a parking lot in the neighboring city of Malmo to avoid riots.
Nevertheless, protests broke out in various parts of the city in southern Sweden, with rioters also throwing stones at the police.
Police officers were not injured, according to a police spokeswoman.
A bus caught fire after strangers threw a burning object at the bus.
The passengers were able to exit the bus in time.
