According to an anonymous report received by Kailoak Suntsitu (a decentralised campaign against the zoos and aquariums in Basque Country), multiple traffic signs as well as walls around Karpin zoo were spray painted.
In said zoo, they use around 200 individuals, which they have locked inside as means for human entertainment, with the excuse that they are helping them.
Animal freedom is non negotiable, close all zoos and 
aquariums!
