Some ambitious hunters managed to kill two moose before realizing moments later that they were actually shooting into an animal enclosure at a zoo.

Recognizing their mistake, the hunters notified the zoo, explaining their elk* hounds had entered the enclosure after giving chase which led to the mix-up.

Zoo officials were shocked about the incident:

"I reacted with disbelief, and the first few seconds afterwards were pretty unreal. I think this is very sad, and it's not OK. We had five elks, now we have only three." Heinz Strathmann, the chief executive of Polar Park zoo, told digital news publisher, The Local.

The local chairman of the wildlife tribunal believes there is no need to punish the men.

"This is a regrettable mistake made in connection with lawful hunting on the outside of the park. It was a fatal error, but everyone understands that it was not done at all on purpose." Arne Nysted told The Local.

*Editorial note: "Moose" is a North American term for Alces alces, the largest extant species in the deer family. In most of Europe and Asia they are identified as "Elk."
