Scuffles have broken out between Croatian police and asylum seekers after they were barred from entering a reception centre meant to register those seeking sanctuary in Europe.
Troubles started at the camp when more migrants came to the gates than authorities could handle. Police in the Croatian village of Opatovac pushed people back from the front gate, asked them to sit down and to wait their turn.
Croatia set up a migrant reception operation to try to bring order to the chaos that has gripped the country since September 15, when Hungary closed its border with Serbia. That decision diverted people fleeing conflict and poverty in the Middle East, Africa and Asia to Croatia.
Elsewhere, Austrian Police say about 1,000 new arrivals are expected soon at the main border crossing point with Hungary, after nearly 10,000 migrants and refugees trekked into the country on Monday.
Police spokesman Helmut Marban said most of Monday's arrivals at the Nickelsdorf crossing east of Vienna had already been brought to emergency shelters elsewhere in the country.
He said Hungary is bringing the 1,000 people to its side of the border by train.
From there, the migrants usually walk into Austria.
Meanwhile, Hungarian MPs say the European Union's "irresponsible policies" have led to the deaths of migrants whose "unbearable flow" is a burden on the country's economic development.
A resolution approved by legislators from Prime Minister Viktor Orban's Fidesz party and its Christian Democrat allies, says Hungary "cannot allow illegal migrants to endanger the workplaces and social security of the Hungarian people".
The officials said it was irresponsible for European politicians to encourage migrants to risk death for a better life in Europe and called on EU leaders to "return to the road of common sense" and protect Europe and it citizens.
Hungary is building fences on border sections with Serbia, Croatia and Romania to stop the free flow of migrants mostly headed to Germany and other richer EU countries.
Norway's Justice Minister has asked the country's police to "intensify" border controls to "prevent illegal immigration and combat organised crime".
Anders Anundsen says such controls give "a better overview and control of who is in the country".
Mr Anundsen said the move was "not about reintroducing systematic" border controls nor "to cut the right to seek asylum in Norway for displaced people".
He added it was up to the national police to find out how to increase surveillance.
In recent weeks, some 2,000 people have sought asylum in Norway which is not an European Union member, but is part of the Schengen agreement allowing travel without internal border checks in Europe.
