(ANSA) - BRUSSELS, 30 LUG - There is alarm in the EU over the decision announced by Budapest these days to facilitate the release of visas to Russian and Belarusian visitors. "The Commission will contact the Hungarian authorities to clarify" because "Russia represents a threat to European security" and "it is necessary to protect the security of the Schengen area", underlined a Commission spokesperson. In recent hours, EPP leader Manfred Weber wrote to the European Council asking for intervention against a measure which "opens the doors to Russian spies" in Europe, he said. (ANSA).
