By an unusual freak of nature, more than 300 wild reindeer have been killed by lighting in central Norway.

The NEA has released eerie images showing a jumble of reindeer carcasses scattered across a small area on the Hardangervidda mountain plateau. The agency says 323 animals were killed, including 70 calves, in the lightning storm.

Reindeer tend to stay very close to each other in bad weather, which could explain how so many were killed at once.

Thousands of reindeer migrate across the barren Hardangervidda plateau as the seasons change.
