Incident marks a fierce escalation in the violence thats rocked the city since june with protests being held with even more frequency and force. A fire has been set here. Riot police are pushing past, trying to flush protesters out. Their routine is well established. The demonstrators are pushed back, first by tear gas and water cannons, and now, it seems, by bullets. Lee cheukyan is a former prodemocracy legislator. We are not fearful and we will continue to fight for our rights, and i think thats a very Important Message for the world to listen that hong kong people will continue to fight. Reporter these protests have now plunged hong kong into a depth of chaos. The city really has never seen. The government is now labeling protesters rioters, and thats important because this automatically extends any possible prison term and prodemocracy activists are now warning that all of this could be pushing hong kong one step closer to martial law. Norah. Ramy, thank you for your incredible re
