Photos: Tiananmen Square then and now
June 4 is the anniversary of Beijing’s 1989 Tiananmen Square massacre, when Chinese government troops opened fire on hundreds of pro-democracy protestors—many of them students—and then went on to lock down the country, arresting survivors and expelling the foreign journalists who witnessed the bloodshed. Images of the incident were banned in China immediately after it happened, but one scene has nonetheless become internationally famous: “Tank Man,” the anonymous, insanely brave young man who dared to step in front of oncoming tanks and stop their advance.
