In this photo taken on June 5, 1989 and made available for the first time by the AP on Thursday June 4, 2009, three unidentified men flee the scene, as another man (background left) stands alone to block a line of approaching tanks (background right) in Beijing's Tiananmen Square. This previously unseen photograph was taken by then-AP reporter Terril Jones and came to light after online discussions of the incident on The New York Times' Lens Blog on the 20th anniversary of the Tiananmen Square crackdown.
