New footage has emerged of migrants being thrown bags of food at a Hungarian camp near the border with Serbia, a media report said on Friday.
The footage from Hungary comes from a camp at Roszke where large numbers of migrants heading north and west have built up.
It was filmed by Michaela Spritzendorfer, the wife of an Austrian Green party politician who was delivering aid to the camp and Klaus Kufner, a journalist and activist.
"These people have been on a terrible tour for three months," Spritzendorfer told the BBC.
"Most of them have been across the sea now and on the boat and through the forest and they've gone through terrible things and we, as Europe, we keep them there in camps like animals. It's really a responsibility of European politicians to open the borders now."
The lack of support for migrants in Hungary has drawn criticism from activists.
