Protesters including Swedish activist Greta Thunberg and members of Extinction Rebellion recently tried to blockade of a gas and oil processing plant in southwest Norway.
In a post to social media, Extinction Rebellion Norway said eight kayaks and three motorboats had entered a security zone outside the Karsto processing plant to "prevent the normal operation of tankers."
Activists, including Thunberg, also gathered on land to block the facility's gates.
"We cannot stand idly by as the fossil fuel industry robs people of their lives and destabilizes our life support systems," Thunberg was quoted saying in the post.
The Karsto plant is operated by Norway's Equinor and is the largest of its kind in Europe, according to the company.
