Police have opened fire on protesters and seven people were injured in rioting that erupted in downtown Rotterdam around a demonstration against COVID-19 restrictions.
The Dutch city's mayor called it "an orgy of violence".
Mayor Ahmed Aboutaleb told reporters in the early hours of Saturday morning "on a number of occasions the police felt it necessary to draw their weapons to defend themselves" as rioters ran rampage through the port city's central shopping district, setting fires and throwing rocks and fireworks at officers.
"They shot at protesters, people were injured," Aboutaleb said. He did not have details on the injuries. Police also fired warning shots.
A number of police were injured in the violence and officers arrested dozens of people and expect to detain more after studying video footage from security cameras, Aboutaleb said.
Photos from the scene showed at least one police car in flames and another with a bicycle slammed through its windscreen.
Riot police and a water cannon restored calm after midnight.
It was one of the worst outbreaks of violence in the Netherlands since coronavirus restrictions were first imposed last year.
In January, rioters also attacked police and set fires on the streets of Rotterdam after a curfew came into force.
Police units from around the country raced to the city to help bring Friday night's situation under control.
Video from social media shown on Dutch broadcaster NOS appeared to show a person being shot in Rotterdam.
Police said in a tweet it was "still unclear how and by whom" the person was apparently shot.
The government has said it wants to introduce a law that would allow businesses to restrict the country's coronavirus pass system to only people who are fully vaccinated or have recovered from COVID-19.
The country has seen record numbers of infections in recent days and a new partial lockdown came into force a week ago.
Local political party Leefbaar Rotterdam condemned the violence in a tweet.
"The centre of our beautiful city has this evening transformed into a war zone," it said.
"Rotterdam is a city where you can disagree with things that happen but violence is never, never, the solution."
