MOSCOW: Seven human rights activists kneeled on Red Square on Sunday and unfurled a banner reading "For Your Freedom and Ours" and three were briefly detained by the police in a demonstration commemorating a similar action by Soviet dissidents 40 years ago who were protesting the Soviet invasion of Czechoslovakia.

Four journalists were also detained, according to news reports and information posted on a blog, moscow-river- 25.livejournal.com, that appears to be connected to the protestors. The demonstrators belong to an organization called the Human Rights Youth Movement and arranged their demonstration to copy as closely as possible the protest action of 1968.
