Border closure threat issued

Bulgarian PM says three countries will not become a 'buffer zone' for migrants

Bulgaria, Romania and Serbia threatened on Saturday to close their borders if EU countries to the north stop accepting migrants, as European leaders prepare for emergency talks on the continent's worst refugee crisis since World War II.

Bulgarian Prime Minister Boyko Borisov said the three countries wanted a Europe-wide solution to the crisis but were not prepared to become a "buffer zone" for the tens of thousands of new arrivals.
