Tens of thousands of people have held a candlelight vigil in Hong Kong to mark the 16th anniversary of China's crackdown on pro-democracy supporters in Beijing's Tiananmen Square.
Demonstrators today (Saturday) demanded that China acknowledge and apologize for the 1989 assault, in which troops backed by tanks killed hundreds of protesters.
The vigil was the only large-scale protest on Chinese soil. In Beijing, security was tight around Tiananmen Square and there were no signs of public commemorations.
In Washington, the U.S. government (State Department Spokesman Sean McCormick) called on China to account for those killed or missing during its crackdown on the protests, as well as up to 250 protesters it says remain in prison.
