Hungary will seal off its border with Croatia from midnight (2200 GMT) on Friday to stem the flow of thousands of migrants arriving daily, Foreign Minister Peter Szijjarto announced after a meeting of the national security cabinet. Szijjarto said the EU leaders' meeting in Brussels failed to decide on a common force to protect Greece's borders, while it was clear that Hungary had to protect the external frontiers of the EU's passport-free Schengen zone.
