Hong Kong police use tear gas on protestors in latest rally

Riot police have fired tear gas and rubber bullets at protesters in Hong Kong following a large pro-democracy rally in the city. This comes only days after a haul of high-explosives were found by police - the biggest haul in the history of the territory. The rally is the latest in a series of protests that have lasted weeks, initially sparked by a controversial extradition deal with China. Our reporter Craig Hoyle is in Hong Kong.
