Hong Kong protests: Leaders threaten to call off talks

Leaders of pro-democracy protests in Hong Kong have threatened to call off talks with the government after demonstrators were involved in scuffles with pro-Beijing supporters.

Protesters blockading key parts of Hong Kong had earlier accepted an offer of talks from Hong Kong's Chief Executive CY Leung late on Thursday.

Protesters have been occupying parts of the city for several days. They are angry at China's plan to vet candidates for elections in 2017.
