Tiananmen Square is quiet on protest anniversary

Police kept China’s symbolic heart of Tiananmen Square free of demonstrators today, detaining at least 13 people while activists abroad marked the 15th anniversary of the attack on pro-democracy protesters.

Since the military assault that killed hundreds, possibly thousands, in the vast Beijing plaza on June 4, 1989, communist leaders have made many changes demanded by the dissidents, scrapping rules dictating where Chinese could work and whom they could marry.
