(CNN)A hunter in Norway shot dead two moose before realizing moments later that he was shooting through the fence of a zoo.
The animals were in the Polar Park Arctic Wildlife Center in northern Norway, about two hours drive south of the city of Tromso, above the Arctic Circle.
The hunter was with a group hunting moose with specially trained dogs at the boundary of the park. One of the dogs went under the fence into the park after the scent of one of the huge animals and the hunter took a shot. His bullet passed through one animal, killing it, and lodged in the stomach of a second, which later had to be euthanized.
