Eyewitnesses say the park was full of people, it was around 7pm on saturday evening and many people enjoying the sunshine, the longest day, having a drink when this attack suddenly began and many people we re suddenly began and many people were forced to flee for their lives. The police said they have arrested a 25 year old man from reading as part of their investigation. They had been searching a block of flats a couple of miles away from the park and residents there say they were told to move out of those flats and then they saw armed officers with shields go into the flats and people talk about hearing a loud bang as pa rt about hearing a loud bang as part of that investigation did the police are stressing that at this moment they do not believe this is a terrorism related incident that they said they are keeping an open mind as to what the motive was and they are being supported by counterterrorism officers. The police were saying, they were urging people to not share footage online. There has been footage online. There has been footage posted on social media of the immediate aftermath of the attack. It is pretty grizzly and that has been shared by a number of people online. Police are saying to think about the families involved and the victims here and do not share that footage but if people do have footage they should pass that on to the police.

She has said that her thoughts are with those affected and for the people of reading who would be shocked and concerned by what she calls and concerned by what she calls a terrible incident she says that she asks for the public to share information they may have with the police. And just before you go, i wanted to clear some things up because inevitably events like this, when they happen, there is a lot of speculation in the media and in the immediate aftermath and in the immediate aftermath and some things dont tend to relate exactly to what has happened. We only find that out later on. This was related in some way to a protest, there is speculation about that, but it was not the case. Yes. There was not the case. Yes. There was a protest taking place reading, a black lives matter protest. It was initially thought by some people that perhaps these two incidents we re perhaps these two incidents were linked but we heard from the organiser of the protest who said that their demonstration had finished long before the stabbing had taken place and there was no link. That has been confirmed by the police who said they are not considering any link between the two events. Police say at the two events. Police say at the moment that they do not believe there is a wider threat to the local community and they are not looking for anyone else in connection with this incident did keeping now is to find out what exactly the motive for this was. President trump has told a rally of his supporters in tulsa in oklahoma that anyone who burns the American Flag should face a year injail. This was trumps first rally since march, when the us coronavirus lockdown began. Although the president said that almost a Million People had requested tickets for the event, the tulsas bank of oklahoma centre, which can host up to 19,000 people, was however far from full. During his speech, trump said he asked for coronavirus testing to be slowed down because the us was having so many positive test results. Ive been speaking about these remarks from mr trump to republican strategist matt mackowiak. I took that as a joke. There was laughter from the audience right after he said it. You know, he said the more you test, the more cases you have, the more negative the coverage is. And thats true. The more important thing is the Positivity Rate and the hospitalisation rate and both of those numbers have remained fairly low in the United States compared to other parts of the world. So i took that as a joke. I understand the media, and some of his democratic opponents will take that literally. And we will see what he says when hes asked about it but it certainly looked to me like he wasjoking. What you make of the fact that the rally is taking place at all . Of course the area where he is, hes speaking in tulsa in oklahoma, which has seen daily records throughout the week of increases in numbers there. Well, 0klahoma was one of the first states to reopen, theyre now in phase three of their reopening. They started reopening 1june. So i think he felt it was one of the safer places to go. Being that he wanted to do this large gathering he needed to go somewhere that had a republican mayor and a republican governor and so tulsa has both. Look, i think this was a test run. The campaign wants to see what the demand is like, whether people will show up to these events, whether they can be held safely, and thats why he wanted to go to a safe place to get that started. Look, weve seen protests, racial protests around the country over the last 3 4 weeks. There have been very, very few questions about the Public Health risk to those events. And so now to see the media turn around and ask questions about the Public Health risk of this i think makes a lot of people kind of scratch their head. So i dont think this rally will matter that much. I thought that he sort of went through his greatest hits tonight. There wasnt a lot of new material. But hes trying to get back in campaign shape. We are four and a half months from the election and he hasnt had a rally in 119 days. And now theyre back on the campaign trail and he will mix that in with his official duties. 0n the messaging, people online and journalists, they are covering it in pointing out he spent nearly ten minutes talking about him walking down a ramp and not really getting a sense of the actual re Election Campaign message. Is that a frustration for you . A little bit. But i will say this. I think when he gives speeches off teleprompters the message is better, but the delivery is worse. You can tell his heart is really not in it. Its not the language he uses. Hes not comfortable doing it. But when he does that in the white house for major speeches i think they go well. In this case, he thinks its more fun for the audience if he sort of riffs. So he does have a telepromter but he does go off script and he wanted to tell a funny story about walking down the ramp at west point 10 days ago. It did take a while and it was a little strange, but it was also kind of endearing in a way as well. So, look, he wants to be authentic in these settings, he wants to be very different from other politicians, and he is very different and that cuts both ways, because he creates problem sometimes with the things he says, but on the other hand thats part of the reason why people show up at these events hours and hours and hours beforehand, because he is so unpredictable. That was the republican strategist matt mackowiak. Now during his Long Campaign speech, the president spoke about the dangers of the Minnesota Police department being dissolved following the black lives matter protests. He used the example of an hombre breaking into a womans home. Hombre is the spanish word for man and is often used offensively to refer to mexican and latin american men in the us. Hey, its one oclock in the morning and a very tough, you know, ive used the word on occasion, hombre. And a very tough hombre is breaking into the window of a young woman whose husband is away as a travelling salesman or whatever he may do, and you call 911 and they say, im sorry, this number is no longer working. 0ur north america correspondent david willis says that despite racial tensions being so high in the us at the moment, the president made little effort to show sensitivity around race. And people have been watching this speech to see what the president would say about the protest about Racial Injustice in this country and the answer to which was very little of virtually nothing. He did say that he has done more for black americans in his four years in office than his presumptive rival joe biden had done in 47 years and that was kind of central to his knocking ofjoe biden, who he also called a shameless hypocrite and a hostage of the radical left. The president , as you mentioned, also recommended that it be a major offence, a criminal offence, for anybody to set fire to the American Flag, an offence which he thought should be punishable by a year in prison. He talked about nominating new conservative justices to the us Supreme Court, the highest court in the land. Thats significant because, of course, this last week has seen the president being dealt two defeats by the Supreme Court. And, overall, he was very keen to get back to this election rally format, we know, we have seen over the years, he enjoys it personally, but behind that he hasnt been doing particularly well in certain polls recently. He hasnt. He has had a pretty disastrous week in various forms and that scene, of course the publication of a book by his former National Security advisorjohn bolton, which is very critical of the president and his ability to govern. We had those setbacks, as i mentioned, in the Supreme Court and we have seen the number of coronavirus cases here in the United States multiply. Added to which, the presents Approval Rating has diminished and all the polls, major polls recently put him quite considerably behind joe biden. Now, there was a lot of speculation that this would be, as the start of his re Election Campaign, a very big rally today, but seems there were some empty spaces in the auditorium and that will not have pleased donald trump. Lets get some of the days other news. The federal prosecutor for new york has said hes leaving his position immediately, after being removed by president trump. Geoffrey berman, who led the investigation into mr trumps personal lawyer, michael cohen, had earlier denied reports he had resigned. Hed originally said he would stay in place until a successor had been confirmed by congress. A usjudge has blocked president trumps attempt to halt the publication of a book written by his former security adviser, john bolton. Mr bolton was fired by mr trump in september after 17 months of serving in the white house. The book includes claims that mr trump had been unaware that britain was a nuclear power, and that he had sought help from chinese president xi jinping to win the president ial election. Health officials in germany say the reproduction number of the coronavirus has jumped to almost 1. 8, the highest value since the middle of march. This was caused by localised outbreaks that affected several hundred people this week. More than 1000 people working at a Meat Processing plant in North Western germany have now tested positive to the disease and Health Experts say the total number of cases injune is still very low. You are watching bbc news, the headlines three people have been killed and others are critically injured after a multiple stabbing in the english town of reading. President trump addresses supporters in tulsa, oklahoma, for his First Campaign rally since the covid 19 outbreak reached the us. Brazil continues to see an increase in cases of coronavirus. A day after passing the one million mark, the country has announced that now almost 50,000 people have died from the virus. Only the United States has more. Katy watson reports. Too many to count, yet each and every one matters. Crying grief so raw, a pain thats grown in brazil every single day. Its a pain that trainee surgeon douglas shares. Seven members of his family got covid 19. His mother and uncle passed away in the hospital where he works. His grandmother also died. My central nucleus of my family was completely destroyed because my mum and my grandmother, because we are an italian family, so the mama is the centre of the family. He was the only one to attend his mothers funeral. The entire family was quarantined. It is the worst thing ever. Because you have nobody to cry with you. You have nobody to give a hug. They are seeing the curve going up, not going down. Do you think bolsonaro is responsible . He has his own part of duty in this, sure. We need, we need a leader and hes not a leader. Hes just another politician. And the politicians have decided that cities should start to reopen. After more than three months of quarantine, life as it was before. President bolsonaro continues to say very little. This is what he is wanted from the start, a return to normality, but there is no such thing as normal here with so many people dying and the virus still spreading fast. 0n the street, though, theres a feeling of trepidation. Public tra nsports full, its complicated, says this lady, who works as a cleaner. Im scared but i have to work, dont i . Doctors are concerned about a second wave before the first one is even over. Jair bolsonaro isnt listening. Its cost him two health ministers, but how will historyjudge him . Maybe the election, the next election, its time. After we go through covid 19, after we spent some time, some years, well look behind and see, well, maybe if wed done it this way or that way, it would be better. But theres no going back. Brazil has joined the us as an exclusive member of a club nobody wants to be a part of. Katy watson, bbc news, in sao paulo. China has given details of its new National Security legislation for hong kong, which would dramatically change the areas way of life. It includes plans for an office in the chinese territory which would collect intelligence. International organisations and hong kong activists have said this would crush hong kongs freedoms. Reged ahmad reports. These are pictures released by Chinese State media as the countrys top lawmaking Committee Meeting in beijing. They are reviewing new draft National Security laws for hong kong, set to be fast tracked and to bypass the territorys own legislature. Beijing says theyre needed in order to target terrorists and separatists. But china has also revealed new details of the legislation that have alarmed many. The striking part, these laws will override any existing legislation in hong kong that conflicts with it. Thats made critics fearful it could erase the prized civil and Political Freedoms that were supposed to be guaranteed for 50 years after the uk handed back the territory to china. Some of the detail reveals that china will have the power to set up an office in hong kong for collecting intelligence. And hong kongs chief executive, appointed by beijing, will have the power to nominatejudges in National Security cases, weakening the independence of the courts in the territory. There is fierce opposition in hong kong to this new law, with those against it saying the bill is far reaching in what it allows. The draft bill itself would ask the hong kong authorities to monitor the activities, the so called separatism activities at school, which creates a Chilling Effect in many ways. And this is what has china worried. Pro democracy protests have been gathering pace in the territory over the last few years, demonstrators even defied coronavirus social distancing laws earlier this month to mark the anniversary of major protests in the city. Chinas proposed laws have provoked an angry international reaction, too, with the European Parliament voting to take beijing to the International Court ofjustice in the hague if it goes through with the legislation. Analysts say beijings new laws could be in place by september, but its hard to see how china can implement them without provoking even more demonstrations. Reged ahmad, bbc news.
