A woman zookeeper died after she was savaged in a wolf enclosure, Swedish public radio said on Sunday.
The 30-year-old woman was alone with eight wolves at Kolmarden Zoo, one of the largest in northern Europe, when the incident happened but it was unclear what led up to the deadly mauling, the radio network said.
The wolf enclosure is well known because the zoo allows visitors into the area to pet the animals.
"Such an event is very rare, but it can happen. Animals living in zoos aren't afraid of humans and accidents can happen," wolf expert Olof Lidberg, told Swedish press agency TT.
