Meanwhile a French diplomatic source told Index.hu, Hungary's leading news website, that Hungarian citizens may be denied free movement within the Schengen zone if its government did not agree to take in refugees. "It is not true that the EU has abandoned Hungary: the reality is that the Hungarian government has so far not come forward with any proposals," the diplomat said.
