The Baltic chain protest
In August 1989, millions in the Baltic states defied the Soviet Union and held hands to demand independence from Moscow.
One of the key moments in the protests in Eastern Europe in 1989 came when millions of people in the Baltic states formed a human chain by holding hands across their three countries. It was a key point in what became known as the Singing Revolution.
Witness talks to one of the organisers of a protest which defied the might of the Soviet Union.
