DHAKA: Footage has emerged of migrants being thrown bags of food at a Hungarian camp near the border with Serbia.
An Austrian woman who shot the video said the migrants were being treated like "animals" and called for European states to open their borders, reports BBC.
The emergency director of Human Rights Watch said the migrants were being held like "cattle in pens".
It comes as Central European ministers again rejected a mandatory quota system for sharing out migrant arrivals.
"We're convinced that as countries we should keep control over the number of those we are able to accept and then offer them support," Czech Foreign Minister Lubomir Zaoralek said at a press conference with his Hungarian, Polish and Slovak counterparts.
The Central European states had already rejected the plan, even though they would take in far fewer refugees than Germany if the EU backs it. European Council President Donald Tusk has said he will call an emergency summit later this month if a solution is not found soon.
In recent weeks, tens of thousands of migrants have been desperately trying to make their way to Europe from war-torn Syria and Libya. Many travel through Hungary to Germany, Austria and Sweden - wealthier EU nations with more liberal asylum laws.
