Hundreds of activists, including Greta Thunberg, have marched through the Swedish capital to a court to file a legal claim against the Swedish state for what they say is insufficient climate action.

More than 600 people under the age of 26 signed the 87-page document that is the basis for the claim, which was filed in the Stockholm District Court.
