Two migrants on bikes cross the boarder between Norway and Russia in Storskog near Kirkenes in Northern Norway, on November 16, 2015. An increasingly popular route for migrants across Russia and into Norway has Oslo angered and worried as winter approaches, while commentators suspect Moscow is deliberately creating problems for its neighbour. Initially, the news that migrants were making a long detour through the Arctic had a whimsical quality to it: migrants have to make the last section of their journey by bicycle because Russian authorities don't let pedestrians cross the border and Norway considers it human trafficking to transport migrants in a vehicle.
