THE HAGUE, Netherlands -- Police fired warning shots, injuring an unknown number of people, as riots broke out Friday night in downtown Rotterdam at a demonstration against plans by the government to restrict access for unvaccinated people to some venues.
Police said in a tweet that “there are injuries in connection with the shots” during the violent unrest. Riot police used a water cannon in an attempt to drive hundreds of rioters from a central street in the port city.
Video from social media shown on Dutch broadcaster NOS appeared to show a person being shot in Rotterdam, but there was no immediate word on what happened.
Police said in a tweet that it was “still unclear how and by whom” the person was apparently shot.
Late Friday night, police said downtown Rotterdam remained restive and there was still a heavy police presence on the streets.
Police said they arrested dozens of rioters and expected to detain more. They said about seven people were injured, including police officers. They did not give further details.
Photos in Dutch media showed at least one police car ablaze and another with a bicycle smashed through the windshield.
Local political party Leefbaar Rotterdam condemned the violence in a tweet.
“The center 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.”
Police said in a tweet that rioters started fires and threw fireworks during the rioting and authorities closed the city's main railway station.
Local media say gangs of soccer hooligans were involved in the rioting.
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 — that would exclude people who test negative.
The country has seen record numbers of infections in recent days and a new partial lockdown came into force a week ago.
In January, rioting broke out in Rotterdam and other Dutch cities after the government announced a curfew in an attempt to rein in soaring coronavirus infections.
Earlier Friday, the government banned fireworks on Dec. 31 for the second straight year. The ban is intended “to prevent, as much as possible, extra strain on health care, law enforcement and first responders,” the government said Friday.
