Hong Kong Holds Tiananmen Commemoration

Commemorations have been held in Hong Kong to mark 26 years since the pro-democracy demonstrations in Beijing's Tiananmen Square.
A crackdown by Chinese authorities on demonstrators left many people dead, with estimates of the death toll ranging from several hundred to several thousand.
Hong Kong is the only Chinese city which is allowed to hold a major commemoration.
But as Lucy Hockings reports, the commemorations have revealed a divide amongst Hong Kong's pro-democracy activists.
