Pictures of the 1968 Soviet Invasion of Czechoslovakia

About 10,000 people marched through the capital today, shouting ''Freedom!'' and ''Russians go home!'' on the 20th anniversary of the Soviet-led invasion that crushed the ''Prague Spring'' of 1968.

Waving Czechoslovak flags, the crowd began a march from Wenceslaus Square after an impromptu rally where hundreds signed a petition calling for the withdrawal of Soviet troops, free elections, the abolition of censorship, democracy and human rights.

Many chanted the name of Alexander Dubcek, who as Czechoslovak Communist Party leader instituted the far-reaching liberalization measures that led to the intervention by troops and tanks of Warsaw Pact countries on Aug. 20 and 21, 1968.
