Tiananmen, 20 Years Later

Chinese honor guard soldiers march against the backdrop of Tiananmen Square and Tianamen Gate in Beijing on Wednesday, June 3, 2009. Foreign journalists were barred from the square, while authorities blocked Web sites such as Twitter and confined dissidents to their homes or forced them to leave Beijing in order to prevent commemorations of the June 3-4, 1989, protests.
