More than 180 people were arrested in 10 Dutch cities as protesters defying a curfew clashed with riot police for a third night running.
Shops in Rotterdam were looted and police used water cannon, as rioters resisted latest Covid restrictions.
Prime Minister Mark Rutte condemned “criminal violence” and the justice minister said the curfew would remain.
The Dutch chief of police said the riots no longer had “anything to do with the basic right to demonstrate”.
The Netherlands has had nearly one million confirmed Covid cases since the start of the outbreak, with more than 13,500 deaths, according to Johns Hopkins University in the US, which is tracking the pandemic.
The government recently introduced a night-time curfew which runs from 21:00 (20:00 GMT) to 04:30. Anyone caught violating it faces a €95 (£84) fine.
What happened on Monday night
There were further violent scenes in many towns and cities. Riot police clashed with protesters in Rotterdam and Amsterdam, as well as Amersfoort, Den Bosch, Alphen and Helmond.
Some of the worst disturbances were in the south of Rotterdam where police said 10 officers were hurt. Across the country 184 people were arrested. Amsterdam’s mayor appealed to parents to keep young people indoors.
Fires were lit on the streets of The Hague, where police on bicycles attempted to move small clusters of men who threw stones and fireworks. There was violence in the southern city of Den Bosch, where rioters set off fireworks, broke windows, looted a supermarket and overturned cars.
A woman living near Den Bosch train station told Dutch radio that masked youths had left a trail of destruction in the city centre. “I saw windows smashed and fireworks going off. Really crazy, just like a war zone,” the woman said. Roads into the city were closed to stop people joining the rioters and Mayor Jack Mikkers imposed an emergency order banning gatherings on Tuesday.
