Though the animals are considered endangered by Russian Federation (the IUCN Red List classifies them as "vulnerable," with a decreasing population), officials said that if non-lethal means fail to drive the bears away, they may be forced to cull the animals, the BBC added.

Head of Novay Zemlya Zhigansha Musin has said that the regime of emergency will be in place until the security of the settlements will be provided.
Hunting the animals is banned and Novaya Zemlya residents have been warned that if they shoot the bears, they could face prosecution.
