Hong Kong Marks 30 Years Since The Tiananmen Massacre

As many as 180,000 people are expected to attend a candlelight vigil in Hong Kong on Tuesday during the 30th anniversary of the Tiananmen Square massacre as commemorations took place in cities around the world on June 4 to remember those who died when Chinese troops cracked down on pro-democracy protesters. Thirty years ago, the People's Liberation Army opened fire and killed from hundreds to thousands of protesters in Beijing after hundreds of thousands of students and workers gathered in Tiananmen Square for weeks to call for greater political freedom. No-one knows for sure how many people were killed as China continues to censor any coverage or discussion of the event that takes place during the anniversary. (Footage by Betsy Joles / Getty Images)
