As part of the anti-NATO summit protests, several blockades were organised to stop, or hinder, access to the red zone - the part of Strasbourg that was completely closed off and where the summit took place.
These blockades were done under the "Block-NATO" umbrella ; one of those, the north blockade organized by "NATO-ZU", was strictly nonviolent.
NATO-ZU, which had it's own barrio and training facilities in the camp, was organised by consensus using a spokesperson council, where each affinity group would send a representative.
