Hundreds of climate activists blocked a major motorway running through The Hague Saturday, urging an end to billions of euros in Dutch fossil fuel subsidies in their "most disruptive" action yet.
The demonstration organised by the Extinction Rebellion (XR) group coincided with a police strike over pensions.
While some police officers on bikes were overseeing the protests in case of emergencies, they were not intervening to break up the demo.
On a sunny early autumn afternoon, the demonstrations attracted a peaceful crowd, with some pitching tents on the tarmac and sitting on the road playing cards.
They placed banners reading "turn off the fossil fuel money taps", "people and the climate above profits", and "if we can destroy the world, then we can also save it."
Loudspeakers blared out speeches, slogans, and bursts of music, including "The Final Countdown" by Europe.
Demonstrators had daubed XR logos and "end fossil fuel subsidies" on the motorway as an elderly group wearing "grandparents for the climate" shirts handed out flyers.
Isabelle, a 25-year-old labour union employee, who refused to give her last name, told AFP: "I think it's essential that we keep raising our voices because this is a cause that matters so much."
"It's an incredibly good atmosphere. People are having fun. There's singing, there's dancing. We're having a good time fighting for our cause."
Many of the activists had conducted a week-long march from Arnhem in the east of the Netherlands that culminated in the protest on the A12 motorway that serves The Hague.
The XR group said some planned to take advantage of the police absence to camp out overnight in the motorway tunnels.
"We will keep coming back until the subsidies are abolished," said XR spokeswoman Rozemarijn van 't Einde, adding that they amounted to between 39.7 and 46.4 billion euros ($44.0-51.4 billion) per year.
The XR group regularly targets the A12 motorway and police often arrest hundreds of protestors.
"The blockade will be the most disruptive since the first blockade on July 6, 2022," said the group.
"The severity of the climate and ecological crisis justifies the additional nuisance."
Dutch Justice Minister David van Weel said police "always act in emergencies, even during work stoppages" so he was not concerned about public safety.
He said it was a "bit ironic" the activists were urging authorities to ensure their safety given they rail against what they call disproportionate and heavy-handed policing.
