During the night from 10 to 11 September 1989, in a dramatic break-up with the Eastern European communist bloc, Hungary gave permission for thousands of East German refugees to leave Hungary for West Germany, via Austria. It was the first time that one of the Warsaw Pact nations broke from the practice of blocking citizens of another communist state from travelling to the West. It was the start of what became the collapse of the Soviet Union and the end of the Iron Curtain dividing Europe.
These pictures were taken on 14 September 2015 at the Hungarian-Serbian border - on the day when Hungary was closed behind an iron curtain again.
