On Saturday, Austrian Chancellor Werner Faymann announced that Vienna was temporarily suspending the Schengen Agreement and toughening border checks.
"Now we have a problem with the direction and organization of refugee flows. We have reached our capacity. And this problem should be solved. I'm sure we will not be able to do this, to achieve a European solution within the European Union in the coming months, so we need to tackle it at the national level," he said at the Euromoney Conference in Vienna.
"If we do not get over the migration problem, we will face the even greater challenge of nationalism," the minister stressed.
The European Union is currently struggling to manage a massive refugee crisis, with hundreds of thousands of people fleeing conflict-torn countries in the Middle East and North Africa.
