Hong Kong:Commemorations marking the 30th anniversary of the massacre of unarmed citizens by soldiers in Beijing's Tiananmen Square in 1989 took place worldwide on Tuesday.
Hundreds of people were killed on June 4, 1989, as People's Liberation Army troops cracked down on pro-democracy protesters in and around Beijing's Tiananmen Square who for weeks had gathered in the heart of the Chinese capital to call for greater democracy as well as political and social reforms.
The biggest event will take place in Hong Kong, the only place on Chinese soil where mass commemorations are held.
A candle-lit vigil has been held in Victoria Park every year since 1990, with hundreds of thousands attending during key anniversaries.
In Taipei, a massive inflatable version of the iconic "Tank Man", who defied the military as they entered Tiananmen Square, has been on display for several weeks.
On Monday, Taiwan's Mainland Affairs Council called on Beijing to "face up to historical mistakes and apologize as soon as possible for the crackdown".
Activists will hold a rally in Washington on Tuesday, with representatives of dozens of human rights groups, including Amnesty International, expected to attend, as well as House Speaker Nancy Pelosi.
