welcome to bbc news, 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. for 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. does this man have the toughest politicaljob in the world? we look at the challenge facing the new prime minister of lebanon.

a cluster of suspected coronavirus cases, after passengers on a plane carrying them home from greece don't bother to put masks on during the flight. it was quite scary, to be honest. as soon as we boarded we realised that many of the passengers hadn't really been educated about the wearing of facemasks. 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 the job 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 why 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. i spoke to assistant politics professor la fleur stepehens—dougan at princeton university and asked her what president trump meant when he said he could solve violent crime in cities. i think this is an effort by the president to kind of show his tough—on—crime, law—and—order credentials and so by saying that you can solve the problem in less than an hour, in about an hour, that is nothing new for him. he has essentially said that he is the only person that can fix it. he ran on that platform in 2016 and it's something that he's trying to do again. now, it is surprising that he has not made a trip to, say, portland, right,

a place where there has been violence for quite a bit of time, longer than kenosha, but he is opting to go to kenosha and i think that speaks to some of his electoral calculations and wanting to win wisconsin, which he did also win in 2016. quite a few commentators look quite a way back to 1968, at the height of the civil rights protest, where actually this law and order line worked pretty well for richard nixon — that appeal to the suburbs who were scared it, did not see it as an issue of police violence and racism, so much as an issue of law and order. yeah, i mean, this is part of a well—worn strategy of the republican playbook, dating back to ‘68 and the southern strategy, first employed by richard nixon, and i think trump is banking that it is going to work for him again. research shows that something like law and order, getting tough on crime, or even discussions on welfare, are part of a racially coded rhetoric where you do not necessarily have to talk about african americans or black people, but essentially racist are part of that conversation

without maybe not necessarily having to explicitly say "black people". this pitch from the more progressive, the more left wing end of the democratic party, is a slight problem, to say the list? defund the police is easy caricature even though in fact it seems to mean divert some funds from the police so it is not always armed police who are turning up, say, to traffic stops or to shop—lifting suspects, but it is very easy to make it a problem for voters. yeah, i mean, ithink it is suffering from a branding problem, you might say. the notion of "defund the police" and trump is trying to use this, you know, people are worried that means you would abolish police, that people wouldn't have police protection and he's playing to those fears, whereas, as you stated, it is really about diverging funds, maybe some to social workers or other resources

so that police could handle the job of policing and not have to kind of take this multifaceted approach for things they are not really trained in. we hear mr biden speaking out against the protests, saying rioting is not protesting. i guess he has to keep trying to present himself as far less left wing than mr trump is trying to paint him. that has upset many in his party. i suppose the calculation for the democrats is that those voters maybe have nowhere else to go. the danger surely is that they stay home as they did for hillary clinton. yeah, this is a quintessential problem that the democratic party faces. we see that no democratic presidential candidate has actually won a majority of white votes since lyndonjohnson and so this is a problem that they have often faced with republicans trying to paint them as left—wing and as radicals. now, anyone who knows joe biden‘s politics knows that he is far from left—wing, that he is a centrist

democrat — a moderate, but this is a strategy that i think is likely to work with many of those sort of suburban housewives that trump is referring to and that is what he is hoping that it will do, instil some of that fear and anxiety about a left—leaning radical. as for the progressives in the party, yeah, there is definitely a danger that they would not be excited about his candidacy. he was never really the first pick of that left—wing of the party and they very well might stay home if he suggests that — his platform is not racially liberal enough and not progressive enough. 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 three tests, but there is opposition to the scheme too. boycott the coronavirus testing, charred some familiarfaces. coronavirus testing, charred some familiar faces. joshua wong and lester shone, prominent pro—democracy activists stopping the involvement of the chinese central government and 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 taken. there are different objections from ethical 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 of just 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 the a cts what is the motive behind the acts to promote the hong kong people from participating in the universal testing. there is only one they can think of which is political calculations. and beijing's hong kong and macau officers have called them radicals with a vile disregard for public health. the idea this 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 isjust emerging central government of china. hong kong is just emerging from a third surge in coronavirus cases that began in earlyjuly stopping 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. i'm joined now by the bbc‘s danny vincent, who is in hong kong. how do you think this is likely to play out? given the fears around the national security law, there is bound to be suspicion of this mass testing isa suspicion of this mass testing is a way of data harvesting by the government in beijing, especially since it is being carried out by officials from the mainland. that's right. on

the mainland. that's right. 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 across the border. there is real concern about issues like that. for ordinary hong kong is, it seems that there is a level of distrust or at least a level of perhaps cooperation. as of last night more than 500,000 hong kong residents signed up to ta ke kong residents signed up to

take this test, it's still a relatively small number compared to the population, but it seems like issues like this, especially with the coronavirus, is 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. since the outbreak of the coronavirus, there's been lots of criticism about the government's response. originally, during what is called the first phase, hong kong actually did pretty well, it wasn't as widespread 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 right now what

were. so i think 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 is something which we are seeing is quite common now in hong kong. all right danny, i know the team and you have been keeping a close ion this, thanks very much. the director general of the world health organization has urged countries to continue to take the pandemic seriously. he said the ‘who fully supports efforts to reopen economies‘ but says ‘no country can pretend the pandemic is over.‘ if countries are serious about opening up they must be serious about suppressing transmission and saving lives. this may seem like an possible balance but it is not. this may seem like

an impossible balance but it is not. it can be done and it has been done. but it can only be done if countries are in control of transmission. the more control countries have over the virus, the more they can open up. opening up without having control is a recipe for disaster. stay with us on bbc news, still to come: stranded. how 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 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. lebanon's prime minister—designate, mustapha adib, has called for a government to be formed in record time. his nomination comes almost a month after a massive chemical explosion devastated much of beirut, plunging the country deeper into a political and financial crisis. lebanon was already on the verge of bankruptcy. his appointment came hours before french president emmanuel macron arrived for his second visit within a month, to press for reforms and action to tackle corruption and waste. following his nomination, mradib immediately paid a symbolic visit to parts of beirut worst affected by that huge explosion at the port. here's a little of what he had to say about the challenges he faces. translation: the opportunity before our country is limited, and the task i have accepted is based on the fact that all political forces are aware of the need to form a government in record time, and to begin implementing reforms immediately.

let's take a moment to look at mr adib‘s background. he's 48 years old and has previously served as lebanon's ambassador to germany. he has a doctorate in law and political science, and previously taught at universities in lebanon and france. he has also served as an adviser to former lebanese prime minister najib mikati, and was endorsed by several other prime ministers over the weekend, before his new position was confirmed earlier on monday. let's get some of the day's other news. the largest faction of japan's ruling liberal democratic party has backed chief cabinet secretary yoshihide suga to become the party's leader. the leader of the ldp will almost certainly become prime minister because of its majority in the lower house ofparliament, replacing shinzo abe who on friday said he was stepping down for health reasons. steve bannon, a former advisor to donald trump who's charged with defrauding a crowdfunding campaign to build parts of a wall along the us border with mexico, has been told his trial

will begin next may. mr bannon is one of four people accused of using hundreds of thousands of dollars to cover personal expenses. all deny the charges. also in the us, a couple who allegedly aimed guns at black lives matter protestors in front of their house in missouri have appeared in court. mark and patricia mccloskey are accused of unlawful use of a weapons, an offence which has a maximum penalty of four years in prison. in the wake of the incident, they were given a prominent speaking slot at the republican national convention. 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, have accused cabin crew of failing to challenge passengers who were not wearing face coverings. all 193 passengers have now been told to self—isolate. 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. the polish statesman lech walesa has warned against the rise of populism. speaking on the fortieth anniversary of the landmark solidarity trades union deal, he said people needed to take the initiative from demagogues, and replace their solutions with wiser ones. the former president was speaking at the gdansk shipyard, it was here in 1980 that a deal was sealed between the communist regime and striking shipyard workers led by walesa which enabled the creation of solidarity, the soviet bloc‘s first free trades union. 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. just sharing some news with you, baby pandas turning one yea rs old you, baby pandas turning one years old at berlin zoo. they celebrated with a cape made from frozen beetroot and sweet potato. the clubs will spend the next four years in berlin with their mother before they are returned to china. 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 gota 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, 16 — 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 21 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.
