Available for over a year

Thousands have joined pro-democracy protests which have spread in Hong Kong on China's 65th National Day. The protesters want China to withdraw plans to vet candidates for the next leadership election in the region (scheduled for 2017). Nuala McGovern hears from some of the demonstrators who have been challenging Beijing and asks them how far they are willing to go in their protest. (Picture credit: Reuters)
