Police in Hong Kong have arrested pro-democracy activists on the anniversary of the Tiananmen Square massacre. Authorities have banned public commemoration of the 1989 incident, which saw China crush peaceful protests in Beijing with tanks and troops.

Hong Kong boosted security around a park Sunday where tens of thousands of people used to gather for an annual memorial of the bloody Tiananmen Square crackdown, ensuring no protests on the event's 34th anniversary.
