UN Condemns Vietnam's Crackdown on Freedom of Expression Lisa Schlein GENEVA - U.N. human rights bodies accuse Vietnam of violating the International Covenant on Civil and Political Rights by clamping down on freedom of expression and denying critics due process and a fair trial. The sentences given to three independent journalists earlier this week are the latest example of a further erosion of freedom of expression in Vietnam. The men were found guilty of national security offenses and sentenced to up to 15 years' imprisonment. U.N. human rights spokeswoman Ravina Shamdasani says an increasing number of independent journalists, bloggers, online commentators and human rights defenders are being arbitrarily detained based on vaguely defined laws. .
