Not everyone in Germany is offering the arriving refugees a warm welcome.
In Dortmund far-right extremists staged a protest at the city’s central station.
Police kept those who came to greet the train and the neo-Nazis apart.
Still three officers and a bystander suffered injuries.
Four people have been taken into custody.
German security forces are currently combating far right networks that are carrying out coordinated arson attacks on refugee hostels.
In recent months the fire bombing of shelters and individual acts of violence against refugees are on the rise.
In one week in late August five arson attacks on refugee hostels were reported in Germany.
After far-right groups clashed with police outside an asylum centre in Heidenau near Dresden last month Chancellor Angela Merkel said the full force of the law would be deployed against those who insulted or attacked refugees.
