Of the many world-shaking events that took place in 1968, high on the list was the movement for reform in Czechoslovakia to create a democratic socialist alternative to the Stalinist bureaucratic dictatorships that ruled the Soviet bloc. Chris Slee takes a look at the movement, which was dramatically ended by a Soviet Union-led invasion.
On the night of August 20/21, 1968, tanks from the armies of the Soviet Union, Poland, Hungary and Bulgaria rolled into Czechoslovakia. The aim of the invaders was to crush a movement for reform.
Austria, as well as Serbia and Croatia, have joined other European countries in temporarily closing their borders.
On September 21, Croatia closed its last checkpoint for trucks on the Serbian border where thousands of refugees are waiting to cross in the hope of a better life.
