Residents in remote part of Russia scared to leave homes after influx of polar bears

Authorities in the remote Novaya Zemlya islands, in the Russian Arctic, have declared a state of emergency after dozens of polar bears began entering homes and buildings, and attacking people.

While polar bears are not uncommon in the region, climate change has been blamed for the unprecedented frequency and large number of the visitors, the BBC reports.

More than 50 polar bears have been spotted in the settlement, home to 3000 people, since December in what local authorities have described as a "massive invasion".

Six to 10 of the bears have been seen frequently in and around a local military garrison.

A cull of the animals is under consideration.
