More than 50 polar bears have descended on a village in Russia's far north.
All public activities in Ryrkaypiy, in Chukotka region, have been cancelled, and schools are being guarded to protect residents from the bears.
Conservationists say climate change could be to blame, with weak coastal ice forcing the bears to search for food in the village rather than at sea.
Other experts have said polar bear visits are now so frequent, Ryrkaypiy should be permanently evacuated.
