We'll take you to Sydney now, where police have declared a stabbing at an Orthodox Church on Monday was a terrorist act. A teenage boy was arrested after a bishop and several churchgoers were stabbed while giving a sermon that was being streamed live online. At least four people were stabbed, but police said none of their injuries were life-threatening. While the Commissioner of New South Wales Police explained why they are treating the attack as terrorism.

The things that influence my decision to declare this a terrorist incident was the actions of the individual who attended, we will allege, attended that church with a knife, armed with a knife, and stabbed the bishop and priest, and others were also injured. We believe there are elements that are satisfied in terms of religious motivated extremism, and of course, the intimidation of the public through that person's acts.

Well, Prime Minister Antony Albanese called for unity in the wake of those attacks.

This is a disturbing incident. There is no place for violence in our community. There is no place for violent extremism. We are a peace-loving nation. This is a time to unite, not divide as a community and as a country.

Let's talk now to our Australia correspondence, Katie Watson, who's in Waukely, the Western Sydney suburb where the attack took place. Katie, good to have you with us. Police describing and declaring that attack as a terrorist act. What has been the reaction where you are?

Well, you can see behind me, there are forensic teams still working in the car park. It's a crime scene, so it's still very early on in investigations. But this was an attack that took place just two days after the brutal stabbing in the shopping center in Bondi Junction. People here are really... I mean, your attention's certainly high. What we saw last night was, of course, the stabbing that was live streamed. Because of that, there were crowds that quickly descended here. Hundreds and hundreds of people came outside and stood outside this church. At some point, they turned on police. There were police injured. At one point, paramedics and police had to barricade themselves in the church and keep themselves inside. Police have also said that the attacker had tips of his fingers cut off. They're unsure whether that was self conflicted or it happened in the riot situation. Certainly, all of this is currently being investigated. There's an awful lot, really, to digest and to try and get their heads around. Obviously, the attack will also the confrontations that we saw afterwards.

Yes, and we know the Prime Minister convening that emergency meeting, also urging people not to take the law into their own hands, referring to some of those protests and some of that unrest that unfolded there. But as you touch on there, these two attacks in short succession in Australia, I wonder what the general feeling is across Australia right now and whether there is a feeling of nervousness given what has happened and unfolded.

Well, certainly, obviously, the attacks aren't connected, but speaking to people here, there's a feeling that what we saw last night was a trigger, if you like, a trauma for many of the community who have fled countries like Syria and Iraq to come to what they thought was a safe place. I think that's something that it was an attack on their religion. It was an attack in the church. Of course, tensions there rose. There's certainly that that discussion is going on about how safe Australia is, and that is replicated across Australia. The conversation I've heard time and time again in these last few days is this thing doesn't happen in Australia, but we've seen it happen, and we've seen it happen twice in the last in less than a week.

Katie, for now, thank you. Katie Watson there, live in Sydney for us. Thank you.
