Security staff check people’s identification at Kastrups train station outside Copenhagen

Security staff check people’s identification at Kastrups train station outside Copenhagen, January 4, 2016. Border checks on train passengers aimed at curbing the number of asylum seekers entering Sweden from Denmark will cost Denmark’s rail operator nearly 1 million Danish crowns ($147,000) a day, the state-owned company said late last month. Travellers have been able to cross borders between the two Nordic countries without passports since the late 1950s. But starting Jan. 4, all Sweden-bound trains will be stopped for mandatory identification checks. REUTERS/Bjorn Lindgren/TT News Agency ATTENTION EDITORS – THIS IMAGE WAS PROVIDED BY A THIRD PARTY.
