Excerpt:
Hungary sealed off a railway track on Monday used by tens of thousands of migrants to enter the European Union on foot, launching a crackdown promised by the right-wing government to tackle Europe's worst refugee crisis in two decades.
With tough new laws and powers to turn back asylum seekers entering into force at midnight, helmeted police officers, some on horses, took up position across the track that traverses the border and has been used for months by migrants, many of them Syrian refugees, to enter the EU from Serbia.
A helicopter circled overhead and a cargo wagon, one end covered in razor-wire, was shunted into position to seal the border.
