Serbian authorities suffered a setback in their bid to relocate hundreds of asylum seekers from a freezing forest on Thursday after a barracks they planned to use was torched following a protest by local residents.
The government in the European Union candidate country has faced growing criticism over its failure to house a rising tide of migrants, mainly from Africa and the Middle East, who have legally sought asylum.
With the arrival of the first winter snow, around 300 migrants have been living rough in a forest because Serbia's two asylum centres are full.
