In the summer of 1989, more than a million Chinese students and workers took to Tiananmen Square in the capital Beijing to participate in communist China's largest political protest in history. The demonstrations lasted for six weeks, culminating in a night of bloodshed on June 3, 1989 when the military forcibly suppressed the protests by enforcing martial law. Hundreds of protesters and residents were killed.
Wednesday marks the 25th anniversary of the massacre, which Chinese authorities continue to treat as a taboo subject, banned from textbooks and websites.
The following images put together by the Associated Press compare scenes of Tiananmen Square during this period of protests and today.
