Environmental activists blocked the A12 highway on Saturday in one of the latest protests against state subsidies for fossil fuels. With little supervision by striking police, about noon around 500 activists marched along the highway leading to the center of The Hague and the seat of the Dutch government.

Accompanied by drums, protesters chanted "The oceans are rising, and so are we." They held up banners that read: "Action Now" and "Stop Fossil Fuel Subsidies."

Some of the protesters brought camping chairs and set up tents to show they planned to spend the night there.

Last year, a government statement estimated that factories received over €39 billion in fossil fuel subsidies, mostly in the form of tax breaks.

The group, which has been operating under the name Extinction Rebellion for years, has vowed to continue protesting until the government ends subsidies.
