welcome to bbc news. i'm simon pusey. our top stories: days after turning down money offered by the g7, brazil accepts foreign help to deal with the fires in the amazon. hong kong police arrest protesters and pro—democracy lawmakers. the crackdown continues with a demonstration planned later on saturday now banned. a trial date‘s set for khalid sheikh mohammed, accused of playing a leading role in planning the 9/11 attacks. and hackers briefly take over the account of twitter‘s chief executive, posting a string of offensive remarks to jack dorsey's 4 million followers.

as fires continue to burn in the amazon rainforest, brazil's military chief says his government is in talks with four countries offering help: chile, israel, ecuador and the united states. the development comes just days after brazil rejected a previous offer of money from the g7 countries. more than 80,000 fires have broken out in the vast rainforest so far this year. sophie long reports from para state, deep in the amazon. this was once lush rainforest, but now sparse land, a result of deforestation in the years gone by. but this year there has been a massive surge in the number of fires set to clear the trees and the landscape along the bau road that takes us deep into the jungle bears the scars of the blazes that are now threatening a whole way of life. in the bau indigenous village they are preparing for a naming ceremony for the latest addition to this tight—knit, traditional community. but as they prepare to celebrate new life, the village chief tells me the threat to his people

is increasing with every day of jair bolsonaro‘s presidency. translation: if the president continues with his policies, he will diminish indigenous lands so that he can confine us and exterminate us. that is what will happen. next year, the burning will be even bigger, but we will be here fighting, resisting. we are prepared to die fighting for our land because we are warriors that are not afraid of the brazilian government. as the fires continue to burn, the smoke continues to rise from the forest. in novo progresso there is a heavy haze all around. it is smothering the city and it's choking its children. carla te silva's three—year—old daughter has pneumonia. she is convinced she contracted it because of the smoke. she says if she doesn't get the right treatment, she could die. translation: the lives of our

children are being jeopardised by people that don't have any sense. they're doing harm to other people, they're just thinking about themselves. it is something i don't have words for. they do the damage and we are the ones who suffer, the children and their mothers. i asked the nurse on duty if children's lives are being put at risk. yes, she tells me, not just the children, it's dangerous for everyone. translation: this is a huge problem. if things keep going like this, unfortunately the consequences will be even worse than the ones we are already witnessing. even though it is not happening inside of our own homes, we are all living in this place. everybody here wants the smoke to go away. even when the fires have been put

out, this is what remains — scorched earth, charred skeletons of trees. the dense rain forest that once stood here is no more, the species that lived in it are gone. all that remains is the flat, black land of deforestation and this has happened in more than 80,000 places across the amazon this year alone. a number of prominent pro—democracy activists and politicians have been arrested in hong kong in a sign that the authorities are taking an increasingly tough line. more street protests planned for saturday have been banned, as the unrest reaches its 13th weekend. from hong kong, here'sjohn sudworth. there are some flashing images from the start of his report. past the waiting press pack, two of the best—known figures in hong kong's pro—democracy movement were swept into court. hundreds have already been detained in this summer of fury, as fears over chinese rule have led to increasingly violent clashes. but, with prominent members of the city's parliament also picked

up, these latest high—profile arrests are being seen as much more political, a point made on the steps of the court after a successful bail hearing. the level of media interest here speaks for itself. far from de—escalating the crisis, the arrest of this young man and others is only likely to fuel concern about the erosion of hong kong's freedoms and legal protections. we are strongly aware of how president xijinping and the beijing government are the ones who back and endorse hong kong police to conduct such mass arrests and prosecution. we hong kong people won't give up and won't be scared by these injustices. today, the police insisted that they are just following the law, threatening further arrests for anyone joining unauthorised

protests this weekend. and here's another warning — more video of chinese paramilitary forces conducting anti—riot drills, although some pro—beijing voices say intervention is farfrom imminent. the messages may dissuade some, but others seem only further emboldened. let's get some of the day's other news. the bbc has uncovered evidence of a war crime committed during a recent airstrike in the syrian province of idlib in which 39 people were killed. the attack by a plane from a russian airbase hit a market in the town of maarat al—numan twice in half—an—hour. moscow has previously denied that the attack took place. the colombian government says nine dissident farc guerrilas have been killed in a military operation in the south of the country a day after one of the former farc leaders, ivan marquez said he was taking up arms again.

the military operation comes amid concerns about the resilience of a peace deal signed three years ago. the long—term outlook for the great barrier reef has been downgraded from "poor" to "very poor" by the australian government agency that manages the world's largest coral system. a new report says rising sea temperatures, caused by global warming, have caused two major events of coral bleaching. fertilisers and pesticides getting in the water have also had an impact. the governor of florida has declared a state of emergency and coastal residents are being urged to stockpile a week's worth of food as hurricane dorian gathers strength. experts say it may be the strongest hurricane to hit the us east coast in nearly three decades. the us national hurricane centre said dorian could cause "incredibly catastrophic damage". ramzan karmali reports. this was hurricane dorian, but not at its peak over the us virgin islands earlier this week. now it

has strengthened into what the us national hurricane centre has cold and extremely dangerous category four storm. by the time is expected to hit early florida next week, it will be generating wind speeds of 130 miles an hour. what really concerns me about hurricane dorian is the multiple threats, the storm surge, the winds, the tornadoes at la ndfall surge, the winds, the tornadoes at landfall and particularly, with this one, the rainfall. because what we think is going to happen is dorian is going to mainland file or hug the coast, slow down and gradually into its way up the coast. that's a disaster, that's a recipe for major flooding. it is anticipated dorian will remain an extremely dangerous hurricane as it moves near the north—western bahamas and approaches the florida peninsula earlier this week —— early this week. florida has declared a state of emergency. we urge all floridians to have seven days worth of food, medicine and water. this is potentially a multi—

day event where it will turn slowly across the state and that obviously creates a whole host of issues. but if you are in an area that has an impact from the storm, you should assume you're going to lose power. and it seems people are listening to the warnings and getting prepared. they've been stockpiling water, food, fuel and materials such as plywood to border properties. sandbags are being billed and collected. and though precautions are being taken, the region is still bracing itself for what could be the worst storm is experienced in over a quarter of a century. ramzan karmali, bbc news. police in scotland have been dealing with what they describe as a large—scale disturbance in the city of glasgow, where a march for irish unity was met by a counterprotest. riot police, officers on horseback and a helicopter were sent to the scene in the govan area of the city. trouble flared when hundreds of people, reportedly from loyalist groups, turned out to protest against a march organised

by an irish republican flute band. a military court in the united states has set a trial date for khalid sheikh mohammad, who is accused of playing a leading role in planning the 9/11 attacks on the united states. he'll be tried in guantanamo bay from january 2021. he's already been detained for more than 15 years. let's get the latest from our north america correspondent peter bowes in los angeles. peter, people will ask why this has taken so long? it has been a logistical challenge, a legal challenge for almost all of these 20 yea rs challenge for almost all of these 20 years since 9/11. khalid sheikh mohammad was sent to guantanamo bay under the administration of george w

bush, that was where the trial was going to be. then president 0bama tried to move the trial, he had planned to take place in a civilian court in new york city, and prompted outrage, outrage from members of the public, there was a real outcry. a lot of complaints and eventually that was dropped. so the trial went back to guantanamo bay and those are some of the reasons why it was marked taken so long, but apart from that it marked taken so long, but apart from thatitis marked taken so long, but apart from that it is an extremely complicated legal case —— why it has taken so long. what is the news of the trial date from family members —— what is the reaction of the news? it's something the family members have been wanting to see very very long time. some may say it has been too long. in that respect it is welcome that the process is moving along because those memories of that day backin because those memories of that day back in 2001 are still very acute for so many people. it was a momentous day, a tragic day for

anyone living in the united states. it was the day that everything changed, the day that ultimately sparked the wall with afghanistan and an entirely new attitude towards global terrorism. there is a sense that everyone just wants to get on with this. almost 3000 counts of murder, practically, how can a trial like this take place? it's going to be difficult. and it's logistically difficult but legally difficult as well because in part it is taking base in guantanamo. and we've got a mixture of civilian law and military law in place as well. so this won't be as straightforward as it might have been if it's a place in a civilian court in the united states, and in particular new york. clearly that wasn't meant to be. so it is going to be difficult. the first stage will bejury going to be difficult. the first stage will be jury selection and that of course, bear in mind, a very high profile case, dealings deal

running high—end people still having very strong memories of the day. the jury very strong memories of the day. the jury selection process in itself could take several months. some a nalysts say could take several months. some analysts say they may struggle to do this by 2021, peter bowes lives in los angeles, thank you very much. —— lives in los angeles. she received a nobel peace prize for her work with the poor the twitter account of the site's co—founder and chief executive, jack dorsey, has been hacked. during the breach, racist remarks were posted by a group calling itself the chuckling squad. twitter says the account is now secure and there are no indications that its own systems have been compromised. let's speak to matthew hickey, who describes himself as an ethical hacker and trainer. he's founder of the cybersecurity company hacker house. he joins me from los angeles. just how can this happen to the company's just how can this happen to the compa ny‘s co—founder? just how can this happen to the company's co-founder? hello, thank you for having me on. the spoofing attack is a widely known issue that

would have failed to address over the last year whereby a person registers with the service and our —— are able to factor their account —— two—factor. so they used his phone number to smoother message due to the —— able to spoof a message to twitter, using his phone number sue for the authentication. a widely known issue —— fool. for the authentication. a widely known issue -- fool. so, if you could be affected by this?m known issue -- fool. so, if you could be affected by this? if you've linked to your phone to your account, and additionally, if they can do sims swapping, they can leveraged the same problems again perhaps for access to your account —— spoof stopping. so it is a issue

that support for short code messages can be abused by sending a text message. so doesn't appear that the customer data was impacted but it is a known issue that twitter have continued to fail to address and we do believe it is something that they should look into in more detail and get a fix up there to protect people. if this technique is a widely used, how embarrassed things that forward twitter and jack dorsey? it's quite embarrassing really that they had this issue there, that it's been known about, certainly something that could be just a long time ago but crowd sourced but forms have demonstrated the use of this attack and demonstrated to me, sending a tweet from a well—known, diseased hacker. this issue was widely known about provided you can send these sms messages. you provided you can send these sms messages. you can use provided you can send these sms messages. you can use this to spoof information to come from authorised

twitter users' accounts. so for the general public, i would advise them to disable their phone number, not link their twitter account to their phone number and also speak to their spoof card and telephone service providers to prevent spoof stopping, perhaps by registering a pin. that is interesting. matthew hickey, thank you very much indeed. thank you having me. stay with us on bbc news, still to come: two british prime ministers, old and new, battle it out as sirjohn major takes borisjohnson to court over a no—deal brexit. she received a nobel peace prize for her work with the poor and the dying in india's slums. the head of the catholic church said mother teresa was "a wonderful example of how to help people in need." we have to identify the bodies,

then arrange the coffins and take them back home. parents are waiting and wives are waiting. hostages appeared, some carried, some running, trying to escape the nightmare behind them. britain lost a princess today, described by all to whom she reached out as irreplaceable. an early morning car crash in a paris underpass ended a life with more than its share of pain and courage, warmth and compassion. this is bbc news, the latest headlines: days after turning down money offered by the g7, brazil accepts foreign help to deal

with the fires in the amazon. hong kong police arrest protesters and pro—democracy lawmakers. the crackdown continues with a demonstration planned later on saturday now banned. live now to hong kong, and bloomberg journalist, aaron mcnicholas, who is covering the protests. a bit ofa a bit of a guessing game at these protests are a bit of a guessing game at these protests a re not a bit of a guessing game at these protests are not authorised. what can we expect later today? descents is, despite the fact they are not officially authorised, that there is still a very wide motivation to come out today. the uncertainty is simply when and where it will start because we have a general location in terms of geography but it is still a very wide area and we don't know where or when it might happen. as i mentioned, the officially authorised march which the mainstream

pro—democracy group, they have been working on getting required police permit for this and the decision was made on thursday that the police are going to object to this proposed march and then on friday, there was an appeal process and that appeal also failed so the march was essentially cancelled because this particular group said that its highest priority was to ensure the safety a nd highest priority was to ensure the safety and the legal safety of its participants so they said they would cancel but there is a sense that people will still come out and the organisation will mostly do it online. life than what we are used to seeing stop — make it will be far more ——it will be far more decentralised than what we're used to seeing. how will the arrests they have just been made to seeing. how will the arrests they havejust been made make an impact? i assume you are talking about the two members of the party, joshua wong and agnes chow. they were arrested in the morning and then

they received bail. the particular gi’oup they received bail. the particular group they represent during the period of detention said that the arrests were away for two things. 0ne arrests were away for two things. one to spread a sense of fear among protesters in hong kong and second, it was an attempt to assume or thrust leadership roles on these two people when they had no such leadership roles in these protests. these protests, as you may know, have been described as leaderless, decentralised and there is a sense that any attempt by the authorities to say that these people are the leaders or those people are the leaders or those people are the leaders will not be logical and won't work because there are no leaders here. those two people are on bail, as i mentioned. we expect to see them today as we expect to see a lot of people but their presence will not make a huge impact on today's events because as i said, there are simply no leaders here and arresting a handful of people simply

will not stop people from coming out to express. it will be interesting to express. it will be interesting to see who comes out on those marches and indeed what happens there. thank you very much for now. here in the uk, a former conservative prime minister has said he willjoin the legal fight to prevent his successor, borisjohnson, from suspending parliament. mrjohnson says those mps trying to block a so—called ‘no—deal‘ brexit undermine his chances of negotiating with the eu. vicki young reports. all: save our democracy... when it comes to brexit, feelings run high. while many in the country welcomed the announcement that parliament won't sit for five weeks, thousands took to the streets in protest. the government insists mps still have plenty of time to express their views. critics say borisjohnson is behaving like a tinpot dictator. when you became prime minister

you talked about uniting the country, but now you're talking about forcing through a no—deal brexit, something that you know democratically elected parliament does not agree with. you're being deliberately divisive, aren't you? we want to do a deal, i've talked over the last few days to lots of leaders around the eu. and everybody can see the rough shape of what needs to be done. it's going to take work, it's going to take a lot of energy for us to get there and the best way to do that is if our friends and partners over the channel don't think that brexit can be somehow blocked by parliament. the weird thing is... but they're trying to block no deal, they're not trying to block brexit, they're trying to block a no—deal brexit. the weird thing is that the more the parliamentarians try to block the no—deal brexit, the more likely it is that we'll end up in that situation. but now this former conservative prime minister says he will challenge mrjohnson in court. sirjohn major knows all about tory fights over europe, they plagued his time in office. today he offered to help campaigners

make their case that the government is breaking the law. that's one battle, the other will be fought in parliament. they'll have less time, but opposition parties and some tories will try to change the law to force the government to delay brexit again. i hope that parliament will take a series of actions in a proper, orderly way that by the end of the week mean, that borisjohnson knows that as prime minister, he has the backing of many, many of us to get a deal, but if he doesn't get a deal, he's going to have to seek an extension. —— to succeed, mps from several parties will need to work together, so are they confident? i'm always hopeful and i don't want to make predictions. all i know is that what we are trying to do is the right thing to do and i believe a majority of mps recognise that a no—deal exit is very damaging to our economy. meanwhile, ministers have promised to step up the tempo on talks with the eu, but ireland's deputy prime minister isn't sounding optimistic. at the moment, nothing credible has come from the british government in the context of an alternative to the backstop. you know, if that changes, great. borisjohnson is being asked vicki young, bbc news, westminster. this weekend will see

the end of an era in paris. the demolition will begin of a huge housing estate on the edge of the city. but this was no ordinary housing estate. it was built to glorify the ideals of communism and it was named in honour of one of russia's favourite sons. the bbc‘s tim allman explains. stark, brutalist, very much of its era. these buildings were supposed to represent the future. now, they are to become a thing of the past. the memories of this woman's time here are still event. we had a toilet and bathroom inside the house, a real kitchen. considering you are in the 1960s, it was modernity. today it might seem outdated but it was something new for me is a little girl. graffiti

tells quite a story. a clue as to why this place is known as gagarin city. yuri gagarin inaugurated the state in 1963. it was built by the local communist led government. calling him a hero of the soviet unions seemed appropriate. translation: it was an extraordinary and popular moment. at that time, gagarin was a hero. it was a form of victory for socialism that had defeated the united states. but now, nearly 60 years later, gagarin city is to be demolished. these buildings will disappear. but the memory of the man they were named after will endure. tim allman, bbc news. that is it from me for now. you can

find more information on our website. i am on twitter. take you for watching, stay tuned. —— thank you for watching. hello there. once again we saw 25 degrees or so across the south—east of england, plenty of sunshine around, further north and west a lot more cloud and outbreaks of rain, in fact the last 2a hours have been very wet across scotland and northern ireland, thanks to this low pressure and this very active weather front which is slowly pushing its way southwards and eastwards all the while, as we head through saturday. so a very wet start in the north and west, temperatures though for most, even though it will be dryer further east, ranging from 12—15. through saturday this weather front will be slowly slipping its way eastwards like i mentioned, but it will be a dying feature, by the time it reaches the eastern side of the country there will be barely anything on it. but from friday through to saturday, a lot of rainfall across northern ireland and scotland, 20—50 millimetres over the high

ground of northern ireland, and 50—80 perhaps across the south—west of scotland, particularly dumfries and galloway. minor flooding will be an issue first thing on saturday, that front continues to journey eastwards, barely anything on it by the time it reaches the south—east. behind it skies brighten up, sunshine, a few showers around, those temperatures will be falling away. the mid teens celsius at best in the north for england and wales, 20—23,24 across the south—east. that is the last of the warmth because as that cold front moves through, it will allow cooler air to spread to all areas. clear skies during saturday night, there will be a few showers packing into northern and western areas, these will be blustery as the wind picks up too, notice the temperatures into single digits, particularly out of town, but even in some of the towns and cities further north. you can see we are into the colder air for sunday, sunday is the first of september, and the first day of meteorological autumn, it will certainly feel like that — you wake up on sunday and it will feel very chilly. lots of sunshine around and showers will get going across scotland,

northern ireland into north—west england, perhaps western wales, some could be heavy with a rumble of thunder mixed in, and it will feel quite chilly when the showers turn up. 12—15 in the north, 16—20 in the south. as we head on into monday, high—pressure wants to build in from the south—west, that will settle things down but you notice this weather front pushing into the northern half of scotland, that will bring more cloud to the north and west of scotland, perhaps outbreaks of rain for the northern and western isles, perhaps a few spots of rain for northern ireland too, but the further south and east you are, because of the high pressure, the winds will be lighter and we should see some sunshine around. so temperatures up a notch on monday, particularly noticeable across the south—east.
