this is bbc news. welcome if you're watching here in the uk, on pbs in america or around the globe. my name's mike embley. our top stories: war of words: joe biden and donald trump put law and order at the centre of the race for the white house. donald trump is determined to instill fear in america. that's what his entire campaign for the presidency has come down to — fear. but i believe americans are stronger than that. four monthsjoe biden has given moral aid and comfort to the vandals repeating the monstrous lie that these were peaceful protests. they were not. it is anarchy. mass covid testing, backed by beijing, comes into effect in hong kong. some call for a boycott.

a celebration of african journalist and kenyan tv presenter wins the award is named in honour of komla dumor. the democratic presidential candidatejoe biden has accused donald trump of stoking violence and sowing chaos in america. in a strongly worded condemnation of the trump presidency, mr biden said his republican rival had failed to do even the basics of thejob in keeping the american people safe. the president has blamed the democrats for violence which has erupted in cities such as portland and kenosha in recent weeks. here's our north america correspondent nick bryant. this was the doorstep of the white house last night — canisters of tear gas fired almost within sniffing distance of the president.

and in this fog of ongoing protest, donald trump sees a clear political opening, a comeback in the polls fuelled by scenes of civil unrest. "law and order," he tweeted today, in what's fast becoming his re—election slogan. and he also attacked what he called the radical left mayors and governors of cities where this "crazy violence" is taking place who've "lost control of their movement". his tweets followed a weekend of violence in portland, oregon, where a white man was shot dead amid clashes between supporters of donald trump and anti—racist protesters. it also came in response to an attack on the president from portland's democratic mayor. do you seriously wonder, mr president, why this is the first time in decades that america has seen this level of violence? it's you who have created the hate and the division. at the start of the summer, in the aftermath of george floyd's death, donald trump's law and order credo didn't have the same cut—through.

but since then, he's refined his message and seized upon the demand of black lives matter protesters to defund the police, even though it's a policy thatjoe biden doesn't actually support. make no mistake, if you give power tojoe biden, the radical left will defund police departments all across america. tonight, the former vice—president delivered his rebuttal, in a speech stressing that rioting was not protesting and in which he claimed that donald trump was a toxic presence, poisoning america. fires are burning and we have a president who fans the flames, rather than fighting the flames. but we must not burn. we have to build. donald trump would much prefer to fight an election focused on civil unrest rather than the coronavirus outbreak. it's electoral terrain that historically has favoured the republicans. the question is, has this summer of black lives matter protests altered that

political dynamic? nick bryant, bbc news, new york. well, in the past few hours, mr trump has been putting his point across in the white house press briefing room. his main point was that the democrats were to blame for the violence in portland and other cities, and he could solve the problem swiftly if they were willing to co—operate. they are, in all cases, democrat—run — but we're doing the best we can to help them without really much of a consent. we'd like to have the consent — as an example, in portland, we could solve that problem in approximately one hour. but the mayor refuses, perhaps for political reasons, i don't know if it's good for him to have a city that's falling apart. and it's under siege now for 94 days. but really, it's been under siege for years, if you know portland. so to the mayor, i say, whenever you're ready, let us know and we'll solve your problem of violence, we'll solve your problem of crime, we'll arrest those criminals very rapidly,

and you'll be able to have some nice evenings in portland. all people living in hong kong can now get a free coronavirus test under a new scheme backed by the chinese government. but a number of pro—democracy leaders, and some healthcare workers, are calling for a boycott. rebecca bailey reports. he has really painted biden into a corner by accusing him of being a socialist, accusing him of being somebody who endorses the violence. and i thinkjoe biden‘s response to condemn the violence on so—called both sides is expected, but also disappointing. joe biden has had numerous times it was inspired to run for president in the wake of the unite the right rally in charlottesville, after which president trump famously said they were very fine people on both sides, referring to white supremacist

protesters and counter protesters. and sojoe biden tactic is to try to deflect some of that criticism by presenting black lives matter protesters and counter protesters, many of whom are associated with extremist or white supremacist organisations as equally violent, and that is simply not the case. they are getting shot in the back. forgive me, i wasjust going to ask you, on that particular point, there are bound to be, oi’ point, there are bound to be, or there clearly are, looking at my feet, many people on the left you are offended by what mr biden is saying. i suppose the calculation in the biden election campaign is, where else are they going to go? those voters are hardly going to vote for mr trump. exactly, exactly. but the risk is that many of those voters will stay home instead of voting forjoe biden, despite not being in agreement on many issues. and i think the real miscalculation

onjoe biden's think the real miscalculation on joe biden's part think the real miscalculation onjoe biden's part is taking people being killed by police officers, by protesters who crossed state lines with semi—automatic weapons, as the same type of violence as property damage. property damages property damage. it is not violence. there are some signs, in the polls, but mr trump's lies about an artist violence, professional agitators, that this is the issue, rather than police violence and racism, but that does play quite well with quite a lot of voters. it does. and i think that is one of the big concerns about the upcoming election, and one of the reasons why i am surejoe biden is being advised to present his own version of law and order. even people in the us who are otherwise very liberal are very concerned about property damage, they are concerned about violence, they are

concerned about crime, and so it isa concerned about crime, and so it is a message that plays very well across the political spectrum, and given the current state of us politics, it is a very difficult one to counter effectively, when you are trying to reach out to swing voters. professorjustin lareau there. all people living in hong kong can now get a free coronavirus test under a new scheme backed by the chinese government. but a number of pro—democracy leaders, and some healthcare workers, are calling for a boycott. rebecca bailey reports. early morning in hong kong. a sleepy start of the first day of mass testing. over half a million people have signed up in advance to take free tests, but there's opposition to the scheme, too. "boycott the coronavirus testing," chant some familiar faces. joshua wong and lester shum, prominent pro—democracy activists. the involvement of the chinese central government in the testing has turned what's on the surface, a public health scheme, into a political row. activists have suggested people's dna will be collected

and abused under the cover of testing. the hong kong government says no dna will be taken and no tests will go to mainland labs. there are different objections from medical experts. for me, the concern about mass testing is the concern about why we are spending so much money on testing lots and lots of people who are going to be negative. i think it would be a better strategy to focus on testing high—risk people, maybe the staff or residents in elderly homes, every week. the head of the hong kong public doctors association told media senior doctors had not been consulted on the plans. but in a sign ofjust how politicised this issue has become, all objections to the scheme have been tarred with the same brush. translation: there are some so—called experts, doctors and individuals, who constantly discredit the universal testing programme, and find excuses to stop residents from participating in the programme. what is the motive behind their acts to prevent

the hong kong people from participating in the universal community testing? there is only one i can think of, which is political calculations. and beijing's hong kong and macau affairs office, called testing opponents anti—china radicals with a vile disregard for public health. the accusation the coronavirus crisis is being used for ulterior motives runs both ways. translation: from the beginning, the government has only had one goal: using the coronavirus control to do whatever it can to please the central government of china. hong kong is just emerging from a third surge in coronavirus cases that began in earlyjuly. the stated aim of this scheme is to fully stamp out the virus and open up society again. but experts have warned that as many as 5 million people might need to be tested for it to work. so the government will be hoping that the controversy

around this testing won't keep people away. rebecca bailey, bbc news. i spoke to the bbc‘s danny vincent, who is in hong kong, about how opposition to mass testing in hong kong will play out and fears that beijing will use the testing to access data. on the surface, this is obviously a health issue, it's related to the coronavirus and the government will say that it's a good policy that they are introducing this measure of free tests for every resident in hong kong, but over the last few months, even issues like this have become heavily politicised. there is a level of distrust, especially amongst democracy activists. they have concerns and fears that this testing system, perhaps some of the dna can be passed to mainland officials, could be sent across the border. there is real concern

about issues like that. for ordinary hong kongers, it seems that there is also a level of distrust or, it seems at this stage at least, a level of lack of perhaps cooperation. as of last night, more than 500,000 hong kong residents signed up to take this test, it's still a relatively small number compared to the size of the population, but it seems that even issues like this, especially with the coronavirus, it seen as simply a political issue now. and it is a huge amount of money now. there is this issue raised in rebecca's report that perhaps this kind of money might be better spent testing every week residents and staff in care homes. well, since the outbreak of the coronavirus, there's been lots of criticism about the government's response. originally, during what's called the first phase, hong kong actually did pretty well. there wasn't as wide a spread as we have seen in other cities and countries around the world. but there was even at that stage criticism from the health officials — sorry, the health professionals who complained

that the government simply didn't act quickly enough. they would have liked the borders with mainland china to be closed even quicker than they were. so i think that right now what we are seeing is another extension of that type of criticism, really. it seems again that it is politicised, at least the authorities would say, and i think to some degree perhaps even the pro—democracy activists would agree, they do think this is a political debate now, but i think to see this level of criticism towards the authorities, it's something which we are seeing is quite common now in hong kong. that was the bbc‘s danny vincent in hong kong. stay with us on bbc news. still to come, stranded — why severe weather has made life miserable for many in parts of western europe. she received the 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 world news, the latest headlines: joe biden and donald trump have criticised each other‘s records on law and order — as they continue their campaigns for the white house. mass covid testing paid for by china comes into effect in hong kong. some call for a boycott. three years ago, a crackdown by the military in myanmar left thousands of rohingya muslims dead, and forced a mass exodus across the border to bangladesh. over a million rohingya people now live in the world's largest refugee camps in cox bazar, bangladesh. every year 20,000 children are born in the camps, knowing nothing of life outside. the bbc‘s bengali service met one of them — three—year—old nayeem. here's his story.

kenyan tv presenter, victoria rubadiri, has been awarded the bbc world news komla dumor award. it was set up in 2015 in honour of our colleague, presenter komla dumor, who died injanuary 2014 — and it celebrates african journalism by uncovering exceptional talent. victoria is the sixth winner of the award — here ‘s how she found out she'd got it. i was overwhelmed. at first i thought i was coming in for a follow—up interview session and next thing they pop up on the screen and say... you have won the bbc's world news award. 0h,

my gosh. oh, wow! i did not see that coming. oh, my gosh. and i just felt a rush of emotion. it was almost like i shifted from someone was almost like i shifted from someone being interviewed to be the easy, you have the award. this is citizen weekend addict i was extremely humbled and honoured, considering that this is no small feat. hello, everyone and welcome to focus on africa. he was amazing. i admired how versatile he was. in one moment you would see him walking alongside a head of state and next he would talk to a group of minors. that kind of

versatility was really admirable. he was authoritative and personable at the same time. i will see you after the game. and he was able to connect and engage with his audience. the bbc has always had a problem with looking cool. that is where i come in. for me he was and still is the epitome of excellence, african excellence. a new rolls- royce on the streets of india, my good friend. him showing that standard to be good enough on the global stage is an encouragement to young african journalists like myself wanting to go to that level. africa can be a global player and it can be a repository of excellence. this is a place

where the world can look to see what can we get in terms of the best the world can offer. i hope that my storytelling and the work that i do as a result of going through this award scheme does that. and also to be an inspiration to other young journalists that you can craft and chart a very unique career path that is authentic to you and, most of all, using this platform to tell a true, real, authentic story of africa. so many congratulations to victoria. tour operator tui has launched an investigation after at least 16 cases of coronavirus have been linked to one of its flights from the greek island of za nte to cardiff. some of those on board the flight, last tuesday, caroline davies reports. sunshine getaways to the island of zante — an appealing prospect to many uk holidaymakers. but for some, travelling back from holiday to cardiff, it wasn't the return they were hoping for. as soon as we boarded, we realised that many of the passengers hadn't really been educated about

the wearing of face masks. many of them were wearing them around their chins, underneath their noses, they were taking them off to talk to fellow passengers. at least 16 cases of covid—i9 have so far been linked to the flight. all passengers on board have been told to self—isolate. lee evans says he was only contacted yesterday afternoon by e—mail, five days after he flew home. i just felt they could have contacted us a lot earlier. it's been a bank holiday weekend, the weather has been kind to us, and i've been out and about, and if i'd known, i would have been in self—isolation today, i would not have done some of the activities that i've done, not wishing to put anyone else at risk. the airline, tui, said there were only made aware of the cases by public health wales yesterday. they say that passengers are informed prior to travel and via pa announcements on the flight that they have to wear masks throughout, and are not allowed to move around the cabin.

masks can only be removed when consuming food and drink. they say a full investigation is under way, as these concerns weren't reported during the flight or before today. but this isn't the first time holidaymakers returning from zante to the uk have had symptoms. last week, local health officials in plymouth said a group of 18 and i9—year—olds had also tested positive. zante itself has introduced its own restrictions, including closing restaurants, bars, clubs and cafes at midnight, and banning more than four people at restaurant tables. it has raised questions about whether there should be localised quarantine for certain high—risk regions, rather than entire countries. if there is enough evidence to suggest that it's a hot spot, and that the social distancing measures cannot be maintained adequately, then there is a case for people not to mix in those destinations. it's not currently the government policy to enforce quarantine for regions, islands or cities. as uk holidaymakers return home, public health

officials are keeping a close eye on new infections. caroline davies, bbc news. parts of western europe have been badly affected by heavy rain and strong winds. at least four holiday—makers were killed in italy, including two children crushed by a falling tree. in austria there have been mudslides, power cuts and rivers bursting their banks. the bbc's tim allman has this. this is normally a football pitch, now it's a lake, where these young men found themselves stranded. it was a similar story in much of western austria. a deluge of wet weather leading to rising water levels and people in danger. in the town of gschnitz there was a fronting operation to stop the local river bursting its banks. translation: it was really serious. we only had 15 to 20 minutes to react. they managed to stop the river breaking its banks and burying the houses in the upper valley.

across the border, in northern italy, the authorities were on high alert. the adige river in verona perilously close to swamping the roads and bridges of the city. this sort of weather is not unprecedented, but experiencing it now is something new. translation: we were used to having flooding around november but it is kind of strange for it to happen at this time of year. translation: they closed the bridge because there was a big tree that got trapped. it started moving so, for safety, they closed it. more rain is expected in the coming days. weather alerts are still in place. it seems the danger has not yet passed. tim allman, bbc news. berlin zoo's baby pandas have turned one. and you can get in touch with me and most of the team on twitter —

i'm @bbcmikeembley. hello. and so, there you have it — we are done, meteorologically speaking, anyway, with summer. but at least it ended on a high note, and this particular corner of aberdeenshire — a glorious end to the day there, captured by tyke, one of our weather watchers. it was that area of high pressure that settled things very nicely across the british isles on monday. but looking out into the atlantic, more disturbed weather is looming just over the horizon. before that arrives, we've got a weakening weather front bringing cloud and rain into the western side of scotland for a time, into northern ireland in the morning. but i think here the cloud will clear, come the afternoon. there will be brighter skies, there will be a wee bit of brightness in the eastern scotland for a time. across england and wales, it'll be a dry day, with a bit of brightness. could get some temperatures higher than monday — won't be difficult — to around 18—19 celsius.

by wednesday, it's those atlantic fronts that are going to bring a combination of cloud and wind and rain to many parts. but it will take a time before the rain moves out of northern ireland and away towards the north—eastern side of scotland — all the while, the rain piling into the western side of england, through wales, as well, some of this quite heavy across the north midlands, wales, and the north of england. but you see, it doesn't really get down into that far south—eastern quarter until quite later in the day, if at all. not too much in the way of breeze here, but it really will be a windy day across the greater part of scotland, particularly in the northwest. bit of brightness up in the north—east of scotland, i6 — you might make 20 further south, where it stays that bit drier. those same weather fronts for the most part get through the northern parts. but in the south, that front becomes aligned with the isobars, so there's no great drive to get that front away from the southern counties of both england and wales. brighter skies follow on behind, but the cloud and a bit of breeze and the odd spot of rain could linger across the south, but it won't stop

the temperatures getting up to around 2! or 22. further north, a slightly cooler feel, but not cold by any means at all. thursday's still a windy old do, across the north—western corner of scotland. this comes back with renewed vigour into the south—western quarter. it may well be that we see some really quite heavy rain. how far north that goes, difficult to tell at this range. but certainly, for the north of wales, northern england, scotland and northern ireland, it's a mixture of sunny spells and some blustery showers, with the high of the day of 20.
