Prague 1968: The Soviet invasion of Czechoslovakia

It's 50 years since the Soviet Union crushed the Prague Spring. Some 250,000 troops stormed into Czechoslovakia to suppress reforms aimed at liberalising the communist country.

A Russian paratrooper and a Czech saboteur agreed to meet in Prague and exchanged views on the events of 1968.
