Plaque commemorating events of November 17, 1989 revealed in Prague

A memorial plaque has been unveiled in Prague's Albertov street where the peaceful demonstration which kicked off the Velvet Revolution started 17 years ago, on November 17, 1989. The student march was organised in memory of Jan Opletal, a medical student killed by the Nazis in 1939. The march which turned into a protest demanding democratic reforms was stopped by riot police and many people were injured. The plaque revealed on Thursday bears the words "Who if not us, when if not now" - one of the slogans of the 1989 Velvet Revolution.
