The BBC’s Carrie Gracie joined protesters on the streets in Hong Kong
Thousands of students in Hong Kong have converged on a university campus to begin a week-long boycott of classes.
They are protesting against China’s stance on electoral reform in the territory. Students from more than two dozen institutions are taking part.
It is a prelude to a larger protest on 1 October planned by pro-democracy group Occupy Central.
Beijing has rejected open nominations for the city’s leadership poll, dashing hopes of those seeking full democracy.
The boycott saw thousands of students gathering at 14:00 local time (07:00 BST) for a sit-in at the Chinese University of Hong Kong campus in Sha Tin, several kilometres north of the city centre.
Most are wearing white T-shirts with yellow ribbons – a colour adopted by pro-democracy activists.
