“We need to take emergency measures to stem the flow of refugees, for example turning them back at the Austrian border or sending asylum seekers immediately on into other German states,” Seehofer said to Bild. 

Seehofer was referring to cabinet discussions which have been going on within the Bavarian government over the past week.

But he did not go into details of how such a policy would work. The Austrian border is controlled by the Federal Police, which comes under the control of the federal government in Berlin, not the Bavarian government in Munich.

Austria reacted with immediate anger to Seehofer’s comments.

“If Bavaria starts to slow down the flow of refugees and to put more controls in place, then Austria will be forced to take similar measures,” Austrian Interior Minister Johanna Mikl-Leitner said in Luxembourg on Thursday.

Bavaria for its part has expressed anger that Austria allows refugees to travel unopposed into the southern German state, meaning thousands arrive daily.

The Bavarian leader’s comments are also likely to bring him into further conflict with Chancellor Angela Merkel.

The two leaders of Germany’s “Union” of conservative parties have repeatedly expressed opposing views on the refugee crisis in recent weeks.

Speaking in Wuppertal on Thursday, Merkel again reassured supporters that she would make a success of the crisis, but that “until then it will require a huge level of national commitment”.
