From Washington Post:
Mainland China remained quiet Thursday on the 20th anniversary of the bloody Tiananmen Square crackdown, while tens of thousands of people staged a protest in Hong Kong.
Beijing, the capital, was on virtual lockdown. Key foreign news Web sites were blocked, dissidents were placed under house arrest, and police blanketed the vast square where a still-undetermined number of pro-democracy activists were killed in a violent clash with the military June 4, 1989. Journalists were kept away from the scene.
Several foreign governments called on Beijing this week to revisit its policy of ignoring the crackdown. Secretary of State Hillary Rodham Clinton said in a statement Wednesday that China “should examine openly the darker events of its past and provide a public accounting of those killed, detained or missing, both to learn and to heal.”
On Tuesday, Congress urged China to agree to a U.N.-backed inquiry into the crackdown, and House Speaker Nancy Pelosi (D-Calif.) said she had directly petitioned President Hu Jintao to free the estimated 30 people still being held for participating in the protests.
