First refugees traveling on Hungarian bus arrive at Austrian border

VIENNA (Reuters) - A number of refugees on their way from Hungary to western Europe have arrived by bus at the Austrian border, a Reuters witness said. Hungary announced on Friday it would send thousands of migrants by bus to the border with Austria, appearing to capitulate to crowds who broke away from riot police and struck out on foot for western Europe in a day of chaos.
