Hundreds of migrants from the Middle East and Asia living in a freezing camp in the forests of Bosnia are short of food and bedding and at growing risk as the bitter Balkan winter approaches, aid workers say. Bosnia has faced an upsurge in migrant numbers since Croatia, Hungary and Slovenia closed their borders against undocumented immigration. In June, authorities in the northwest Bosnian town of Bihac moved migrants who were sleeping rough there to an tent settlement at Vucjak, a former landfill site 8 km (5 miles) from the Croatian border. Aid agencies have urged the authorities to close Vucjak and find better accommodation for the migrants as the weather gets colder. REUTERS/Marko Djurica SEARCH "BIHAC CAMP" FOR THIS STORY.
