Danish police closed a motorway and rail links with Germany on Wednesday in a bid to stem the flow of refugees heading north to Sweden, as Europe's migrant crisis spreads northward.
The motorway, a vital traffic artery for people and goods between the two countries, was closed when some 300 refugees, including children, began walking on it. Police tried to persuade them to leave but appeared reluctant to use force, witnesses said.
"We are trying to talk to them and tell them that it is a really bad idea to walk on the motorway," a police spokeswoman said.
Police also asked the state-owned railway operator to stop all trains between Germany and Denmark until further notice.
