On the eve of the anniversary, a memorial plaque was unveiled on
Prague's Albertov street where the peaceful demonstration, which kicked
off the Velvet Revolution, started on November 17, 1989. 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.
