In hong kong, a Senior Police officer has said that unrest has brought the territory to the brink of total collapse. In the latest clashes with democracy campaigners, the violence spread to a university campus, where police fired tear gas, rubber bullets and water cannon. Some of the protesters built barricades and threw petrol bombs. Our correspondent robin brant was there. Yelling. Run, she is shouting in cantonese, and they are running, but not for fun. Hong kong students at their university racetrack were escaping the tear gas and rubber bullets as police raided their campus. Moving onto the grounds of the Chinese University is a marked escalation by the police. They said they needed to stop people throwing bricks and other Dangerous Items from a campus bridge onto passing traffic. By night, that bridge became the front line in a stand off, police on one side, protesters on the other, a raging fire in between. 2a hours previously, this place had been completely normal. Across the university, protesters and students formed a human chain to supply the front line with water and food. Others sat in groups, preparing their supply of weapons. Youre sitting here making kind of, for want of a better phrase, petrol bombs. Why we are doing this . Because yesterday, you know, they used real bullets, shoot our right in the chest, and that can kill someone. So, if they upgrade their weapons, we need to upgrade our weapons to protect ourselves, too. This scene shows you how drastically the nature of this confrontation has changed. It started out five months ago with hundreds of thousands of people marching on the streets in peaceful demonstration. Now, at the entrance to a university, there is a roadblock on fire, a burnt out car blocking the entrance to this bridge, and around me, dozens of protesters in black sitting and waiting, not knowing whats coming next. The start of this week has been different here, the stand off at the university more dangerous. In its sixth month now, this particular part of the protest felt less like a confrontation and more like a conflict. Robin brant, bbc news, hong kong. Raging bushfires have damaged Properties Across parts of australia and briefly spread to suburbs of sydney. The catastrophic day that was forecast has so far not materialised, but there are still 7a uncontained fires burning in New South Wales. Fire chiefs are warning the dangers facing the state and neighbouring queensland are far from over. Our correspondent phil mercer has more from sydney. This toxic haze, mike, that smothered much of sydney and a vast swathe of New South Wales has mercifully been blown away by very strong winds. This part of the country is no longer under those catastrophic fire warnings. But we now hear that, since this emergency began on friday of last week, about 200 homes have been destroyed, and sadly, three people have lost their lives. Those fires you refer to in suburban sydney, about 15 km from the harbour bridge, there is a suspicion that they may have been started on purpose. So bushfires for the australian community, theyre traumatic, they are devastating, and they are frightening. To hear that some of them may have been started on purpose will anger and frustrate an entire nation. So phil, what is likely to make the difference, the most difference, in the next few days . Well, here in New South Wales, more hot and windy conditions are forecast for the end of the week. Further north, in queensland, theyre facing dangerous conditions right now. It is all hands on deck. There are evacuations in popular holiday destinations in the state of queensland. So, while firefighters in New South Wales, though still battling many, many fires, are having something of a respite, their colleagues to the north are finding conditions very, very tough indeed. And were hearing that queensland has drafted in firefighters from as far away as new zealand, because the dangers up there are so severe. Lets get some of the days other news the former treasurer to the vatican Cardinal George pell has been granted a right to a final appeal in Australias High Court against his convictions for child sexual abuse.

Until now, the testimony has been heard behind closed doors, although widely leaked. The eventual trial will be in the republican controlled senate. But for now, democrats in the house of representatives are looking at whether President Trump abused his power by witholding military aid from ukraine while pressing the government in kiev to investigate his political rivaljoe biden and his son. Mr trump calls the inquiry a hoax. The first two people in front of congress on wednesday are bill taylor, the top us diplomat in ukraine, and george kent, Deputy Assistant secretary for european and eurasian affairs. On friday, former Us Ambassador to ukraine Marie Yovanovitch is due to testify. President trump has announced that he will probably release more notes from his conversation with ukraines president by the end of the week. Our north american correspondent david willis has more. This will be the first public testimony. Indeed, it will be the first televised impeachment proceedings in the us in 20 years. Lots of people will be watching, of that we can be absolutely sure, because there will be blanket coverage here, both on Cable News Networks and on the main networks here. Not since watergate, of course, have we seen such interest, i think, in impeachment proceedings. And these two witnesses who are due to give evidence tomorrow are seen as highly credible, certainly as far as democrats are concerned. William taylor, the top us diplomat in ukraine, george kent, the senior the state department official, are both expected to articulate their concerns about a sort of shadow ukraine policy that was being implemented, in their view, by President Trumps personal lawyer rudy giuliani. Now, well hearfrom Marie Yovanovitch, the former ukraine Us Ambassador to the ukraine, on friday. And its been announced, mike, that there will be eight other witnesses giving testimony in public next week. And david, just on another important point, the Supreme Court has given a strong indication, hasnt it, that it plans to take mr trumps side on an immigration issue that affects hundreds of thousands of people. Thats right. Its been hearing oral arguments today, mike, to do with that plan by the trump administration, or that intention by the trump administration, to scrap whats known as the daca agreement. That would basically abolish protections for about 700,000 immigrants who came to the United States as children, through no fault of their own, illegally. And, of course, they were given an extension by the 0bama administration. Mr trump wants to take that away. He wants to abolish the so called daca programme. And attempts to do that have been frustrated by the court, so this matter has gone all the way to the highest court in the land, which was hearing evidence today. It has some time, though, before it will deliver its verdict. Thats not expected until the middle of next year, by which time, of course, the 2020 president ial campaign will be in full swing, during which its expected immigration will of course be a key factor. And just very briefly, david, mr trump has sent very mixed signals on the dreamers, hasnt he . He has, yes, indeed. Today he tweeted that, although some of them were in his view criminals, there would be some attempt to basically Reach Agreement with the democrats, were the us Supreme Court to vote in favour of his administration in striking down the daca programme. It remains to be seen, of course, what sort of shape that agreement would take, because previous attempts by this administration or previous assertions that the administration would actually collude with the democrats over the subject of immigration have of course so far come to nothing, mike.

The israeli leader, Benjamin Netanyahu has warned there could be a protracted flare up of tension with militants in gaza following israels killing of a senior islamichhad commander. Sirens sounded in ashkelon in the last few hours, as palestinians militants launched another rocket attack into the israeli city. At least 150 rockets have been fired. And dozens of israelis have been treated for injuries as an indirect result of rocket fire. Israel says air and Ground Forces hit sites inside gaza throughout the day. The Hamas Run Health Ministry says three palestinians have been killed and about 30 wounded in the attacks. Tom bateman has the latest from the israeli gaza border. Well, the firefighters have spent really all of today trying well, the firefighters here have spent really all of today trying to douse these flames and still as you can see, there is smoke emanating from this building. It is a warehouse that took a direct hit from a rocket fired from gaza. I was speaking to the owner who said it was only really a matter of luck, that it was just too early for his staff to have been in the building so they had a very lucky escape. As we arrived here, we heard several loud blasts. It has been hard to distinguish the anti aircraft fire or the anti missile fire from israels Missile Defence systems from very powerful air strikes israel has been carrying outjust a couple of miles away on the eastern side of the gaza strip. Weve seen smoke rising from some very loud blasts in what has amounted to one of the most serious exchanges of fire between militants in gaza and the israelis in the last 18 months, all starting with that targeted killing of al ata this morning. Israels Prime MinisterBenjamin Netanyahu described him as a ticking bomb, posing an imminent risk to israeli civilians and soldiers and thats why he said this operation took place. As for the palestinians, the dominant militant group in gaza, hamas, said this action crossed a red line, vowing a response and so weve had rocket attacks from islamichhad all day into israel, sirens continuing, and those air strikes, with israel now targeting militant sites, killing another three palestinians according to Health Officials in gaza. What happens now, i think, in the next few hours or so will be decisive, to see whether or not this escalation continues. The militants in gaza have vowed to resist, to respond. The israelis have said that they dont seek an escalation but they are prepared for one.
