In some places, according to the drivers, there are so many that the road is just a slippery" - the journalists Norwegian portal Barentsobserver.

The reason for the mass migration of rodents in regions such as Lapland and Finnmark, according to scientists, was an extraordinary increase in their population this year. In the north, over a wide area in the border area between Finland, Norway and Russia lemmings - just about everywhere.
