Transcript for Police fire warning shots, tear gas amid Hong Kong protests
We'll go to Hong Kong where we're seeing some of the most intense clashes yet. Officers fired water cannons and tear gas and warning shots. Ian Pannell is on the scene, good morning, Ian. Reporter: Yeah, good morning, George. That's right. This is a city shaken to its core by a weekend of violence. Overnight the police releasing a statement condemning the protesters for the battles that raged across the city for hours and hours over 9 weekend and taking a dangerous new turn. Anarchy on the streets of Hong Kong. Police firing a warning shot even pointing their guns directly at demonstrators using live ammunition for the first time since this three-month fight for the future of Hong Kong erupted. One officer losing control with an unarmed protester. Water cannons deployed onto the streets. Protesters charging police with sticks, bricks and umbrellas. Police firing a relentless barrage of tear gas. There's more tear gas canisters being brought forward as some of the protesters are literally picking them up trying to throw them back. Forcing us to take cover. The air thick with smoke and anger on both sides. This is certainly the worst situation we've seen, the most violence, the most tear gas and the most resistance from the protesters. The question now is how long will China tolerate these scenes? Police say 21 officers were injured over the weekend and had no choice but to draw weapons because they were facing a life-threatening situation. This all 86 protesters arrested, the youngest just 12 years old. And the reminder that China has said that it'll move across the border if the Hong Kong police can't control the situation and there were brief moments over the weekend where it started to look like that. George. Okay, Ian, thanks very much.
