Tens of thousands of people attend a candlelight vigil at Victoria Park in Hong Kong Thursday, June 4, 2015. Hong Kongers joined the candlelight vigil Thursday night marking the crushing of the 1989 student-led Tiananmen Square protests, an annual commemoration that takes on greater meaning for the city's young after last autumn's pro-democracy demonstrations sharpened their sense of unease with Beijing.
