Checkpoints and rows of police vehicles lined a major road leading to Beijing's Tiananmen Square as China heightened security on the 35th anniversary of a bloody crackdown on pro-democracy protests.
China has long quashed any memory of the killings, when the Chinese government ordered in the army to end the months-long protests and uphold Communist rule. An estimated 180,000 troops and armed police rolled in with tanks and armored vehicles, and fired into crowds as they pushed toward Tiananmen Square.
