This gorilla gives headaches to tourists! Carers did not come to believe what it is able to do!A gorilla at the zoo in Berlin hates being visited by tourists,and especially photographed. The mammal is so annoyed by this visitors, that is unpredictable and very aggressive. A group of tourists from Ireland filmed an angry reaction! They approached the gorilla enclosure and one of them started to film. Apparently the gorilla was curious about the guests, and came towards the tourists. But when least expected, the gorilla threw a rock towards them. Almost targeted the cameraman!
