Nicholas Kristof of The New York Times was in Beijing during the events of 1989 which culminated in the June 4th Tiananmen Square massacre. In a series of short audio recordings, he recounts the events as he remembers them.
Also from the Times, a discussion of the famous Tank Man photo (more accurately, photos), can be found here.
As the 20th anniversary of the massacre approaches, the Chinese Government has closed Tiananmen Square, and blocked such internet sites as YouTube, Twitter, Flickr, Hotmail, HuffPo, Blogspot, and others.
Update: The Tank Man from a never-before-seen angle.
