The Latest on the 27th anniversary of the Chinese military's bloody June 4, 1989, crackdown on pro-democracy protests in Beijing's Tiananmen Square (all times local):

7:45 p.m.

People are starting to filter into Victoria Park in Hong Kong's Causeway Bay district as the city prepares to hold an annual candlelight vigil on the 27th anniversary of the Chinese military's bloody crackdown on student-led pro-democracy protests in Beijing's Tiananmen Square.

Organizers are expecting 100,000 people to attend, though the threat of rain may keep numbers down.

The annual event is the only large-scale public commemoration of Beijing's brutal crackdown held on Chinese soil.

The vigil is organized by the Hong Kong Alliance in Support of Patriotic Democratic Movements in China. It demands that Beijing overturn its verdict that the Tiananmen protests were a counterrevolutionary riot. It also calls for one-party dictatorship in China to be replaced by democracy.
