hello, i'm sumi somaskanda. thank you forjoining us on bbc news. the governor of brazil's sao paulo state has declared three days of mourning after a plane crash killed all 61 people on board. a warning — the following pictures leading up to the moment of the crash are distressing. footage on social media shows the aircraft spiralling out of control. the cause of the crash remains unclear. the airline, voepass, said the plane was en—route to the main airport in sao paulo city when it came down in a residential area of vinhedo. authorities report no—one on the ground was injured. relatives of the victims gathered at the airport from where the plane as they anxiously await more information of their loved ones. brazil's air force is investigating the crash and said at a news conference that, at this point, there was no indication from the aircraft that there was an emergency. sao paulo security officials say they recovered the plane's black box — a device that could give investigators vital information of the moments leading up to the disaster.

meanwhile, firefighters, military police, and state civil defence are all deployed at the scene. following news of the crash, brazilian president luiz inacio lula da silva paid tribute to the victims with a moment of silence at an event where he was speaking. joining me live is flavio antonio coimbra mendonca, a former brazillian air force officer. thank you so much forjoining us tonight. such a tragic story. i would like to get your reaction to what we have seen with this tragic pawleena crash. . ~' , ., with this tragic pawleena crash. . ~ ., ., crash. thank you for having me. i would like _ crash. thank you for having me. i would like to _ crash. thank you for having me. i would like to start _ crash. thank you for having me. i would like to start by - i would like to start by expressing my deepest condolences to the families and loved ones of the 61 people who lost their lives in this tragic accident. my thoughts and prayers are with you during this incredible difficult time. as a former investigator, i am

confident that brazil will have the expertise to investigate this tragic aircraft accident and figure out the contributing factors that we can prevent future accidents.- factors that we can prevent future accidents. looking at the investigation _ future accidents. looking at the investigation taking - future accidents. looking at. the investigation taking place right now, we know that several differences on the ground and police investigators, can you give us an idea from your experience what is going on in the investigation right now, what they will look for? they will be looking _ what they will look for? they will be looking for, _ what they will look for? they | will be looking for, especially the highly perishable, for example, some of you samples and, of course, the important piece of process will be the flight data recorder in the cockpit so that the accident investigators can have a much better picture of the moment

leading to the accident. we clearly do _ leading to the accident. we clearly do not _ leading to the accident. we clearly do not know anything at this moment about what caused the plane to crash and we do not want to speculate where we have seen the horrific images on social media over the plane spiralling out of control before it crashes. what do you think when you see those images? i think when you see those images?— think when you see those imaues? ., , ., , think when you see those imaes? ., , ., , ., images? i have seen a couple of imaaes images? i have seen a couple of images on _ images? i have seen a couple of images on social— images? i have seen a couple of images on social media - images? i have seen a couple of images on social media and - images? i have seen a couple of images on social media and tv i images on social media and tv and i have also seen the investigation process, some people have information on the weather was poor, so they could have been a factor leading to some kind of stall and perhaps stalling, and maybe this was — it is too early to determine the probable cause of the accident but that is something the investigators will look at and try to get more information of so they can have the final report. the most important thing will be the inaudible to

prevent future similar accidents. , ~ ., accidents. absolutely. what can ou tell accidents. absolutely. what can you tell us _ accidents. absolutely. what can you tell us about _ accidents. absolutely. what can you tell us about the _ accidents. absolutely. what can you tell us about the safety - you tell us about the safety record of this airline and also this aircraft, which was a twin engine turboprop? i this aircraft, which was a twin engine turboprop?— engine turboprop? i am not familiar with _ engine turboprop? i am not familiar with this _ engine turboprop? i am not familiar with this airline. i l familiar with this airline. i have been out of brazil for 1h years but i know it is a safe aircraft model, so many airlines fly this model all across the world. again, it is too early to say anything about probable cause. i think we have to do more data collection and the next step would be the data analysis and maybe do the process it can go back to the data collection and get more information to be necessary. i have seen on tv in brazil that the aircraft accident investigators were able to find the cockpit voice recorder and a flight data recorder, they are important pieces of elements to the accident

investigation process. absolutely, they are hoping they will provide further clues. forthose they will provide further clues. for those who are not familiar with flying in brazil itself, how good is a safety record for airlines in brazil? it is a very safe airline industry. brazil is among the top safest lesions all across the world, it is a safe country to fly. the world, it is a safe country to fl . ~ ., ., ., to fly. we will have to live a conversation _ to fly. we will have to live a conversation there - to fly. we will have to live a conversation there for - to fly. we will have to live a | conversation there for today but thank you so much for joining us on bbc news tonight. with less than 90 days remaining until the us presidential election, the two rivals for the white house are on the campaign trail drumming up support. crowds of kamala harris supporters are waiting for the presumptive democratic presidential nominee to appear at a rally in phoenix. this is a kamala harris live right now. tim walz was on the stage previously. vice president harris is on a whistle—stop tour

of some of the most closely—contested states and is aiming to capitalize on a surge in the polls. it looks like kamala harris has wrapped up her speech and onstage at the moment, we are seeing bozeman montana, where donald trump is due to appear shortly. his supporters have gathered there, taking place in the next few hours and donald trump expected to take the stage. his plane diverted to the city of billings duty mechanical issue. he is in montana to support tim sheehy who is running for a key us senate seat and bbc news confirmed it will moderate the first debate between the presidential candidates as agreed on 10 september. joining me live is politics editor at the washington monthly, bill scher. good to have you on bbc news tonight. we have the split screen again of the two rivals are different rallies and events also started with kamala harris and tim walz in arizona

at another packed stadium there. it seems like the democrats believe there is a key battleground state is now in play? i key battleground state is now in -la ? ~ key battleground state is now inla? in play? i think democrats believe all _ in play? i think democrats believe all the _ in play? i think democrats. believe all the battleground sees are in play for them. there was a sense whenjoe biden was still going to be the nominee that he was left with a narrow path to the minimum 270 votes and that was the rustbelt path of michigan, pennsylvania and wisconsin and even the polls are looking dicey. ever since kamala harris has become the nominee, she has improved their standing the nominee, she has improved theirstanding in the nominee, she has improved their standing in those rustbelt states but also improve her standing for what polls we have seen so far in the sunbelt states, particularly georgia and arizona. i do not think we know as much about north carolina gap in the democrats think they can make a playful estate as well. ., ., well. looking at the donald trump holding _ well. looking at the donald trump holding the - well. looking at the donald trump holding the rail- well. looking at the donald trump holding the rail in i trump holding the rail in bozeman montana he is there to support tim sheehy, and this

will be a closely contested senate seat. montana is a republican country but why is this important for republicans? it is extremely important, some people mock front because he is not in a battleground state authority presidential race is concerned. this schedule in those swing states has been weirdly light but the montana senate race may determine which party controls the senate. it is a republican cbd republican jon has defied political gravity several times now and republicans need to net two is to take control of the senate if the democrats hold onto the white house. they are likely to already pick up one in west virginia wherejoe mention, virginia where joe mention, another virginia wherejoe mention, another right wing democrat is stepping down, so they need one more. according to the polling we have, montana is their best shot. in that respect, it makes sense for donald trump to be there. it sense for donald trump to be there. , . , sense for donald trump to be

there. , ., , ., there. it is really important when democrats _ there. it is really important when democrats and - there. it is really important - when democrats and republicans look at the balance of the house of representatives in the senate. looking at the fact that there has been the surge in the polls for kamala harris and her running mate tim walz, how is donald trump and how his team reacting? i how is donald trump and how his team reacting?— team reacting? i think the trump team _ team reacting? i think the trump team is _ team reacting? i think the trump team is reacting i team reacting? i think the - trump team is reacting badly, they did not seem to have a game plan in place. for the swap, even though they were mocking joe biden's received mental decline and suggesting he should get off the ticket and when kamala harris got in there he did not seem to know what to do. he threw everything against the wall to see what sticks. as opposed to having a clearly defined line of attack, and so far nothing seems to be sticking, the democratic base has consolidated an kamala harris media coverage has been positive, and you see the trump team get frustrated with that and complain about the media. when you complain about the media you are not attacking the

candidate, so they are still in a period of uncertainty right now. at a period of uncertainty right now. ~ ., a period of uncertainty right now. �* ., ., , a period of uncertainty right now. ., ., , ., now. a lot of people have speculated _ now. a lot of people have speculated this _ now. a lot of people have i speculated this honeymoon period for kamala harris and tim walz will wear off. what is it the challenges will be for her and her it the challenges will be for herand her campaign and it the challenges will be for her and her campaign and tim walz as well as they start going out more and more on the campaign trail? the going out more and more on the campaign trail?— campaign trail? the harris campaign _ campaign trail? the harris campaign has _ campaign trail? the harris campaign has been - campaign trail? the harris campaign has been able . campaign trail? the harris| campaign has been able to campaign trail? the harris - campaign has been able to gain roughly four orfive boys in polling nationallyjust by doing a staged events. they have not felt compelled to do unscripted media interviews, press conferences, town hall, anywhere where you cannot solely control the message. they have not done so far and has been fine you can only do that for so long, give the same some sweet and expect to get nice media coverage. the day will come when they have to do more unscripted things and there are lots of outstanding questions she has the answer. she shifted her position on various issues and everything is in the biden it records you may be asked about like their record on the border, israel,

withdrawing from afghanistan, past inflation. people will properly ask her if she felt there was something wrong with joe biden's held that she was to share with the public. not saying they are necessarily things she can't answer but she has not been put to her yet we do not know how she will as he is a be unknown.— is a be unknown. interesting oint is a be unknown. interesting point there- _ is a be unknown. interesting point there. thank _ is a be unknown. interesting point there. thank you - is a be unknown. interesting point there. thank you so i is a be unknown. interesting i point there. thank you so much forjoining a site on bbc news. russia's war in ukraine is now drawing much closer to home, after a major incursion into russian territory, by ukrainian forces. a state of emergency is in effect in russia's western kursk region, with moscow saying up to 1,000 ukrainian troops are involved. reports suggest they could be operating up to 20 miles inside russia, with intense fighting, close to the town of suja, which is home to a nuclear plant. the un nuclear agency is urging russia and ukraine to exercise maximum restraint. these pictures, verified by the bbc, show a 15—vehicle russian convoy, badly damaged and burned in the kursk region. the person who posted the video, has now been arrested.

russia is striking back — ukrainian authorities say 1a people have been killed in a missile attack in the east of the country. more on that in a moment. but first, steve rosenberg has the very latest from moscow. it is an astonishing sight. russian jets scrambling to bomb russian territory. they are targeting ukrainian troops, who've attacked in large numbers across the border. it came out of nowhere. the ukrainian assaults on russia's kursk region began on tuesday and suddenly russia's war had come much closer to home. this drone footage from a ukrainian military unit is purported to show russian soldiers surrendering. several villages have been seized. in the border town of sudzha residents recorded this video appeal to vladimir putin, calling on the kremlin leaderfor help. "the chief of the general

staff told you that "everything is under control," this man said. "but there are big battles going on around here." president putin met his security chiefs to discuss the battle against terrorism. he has called the ukrainian attack a provocation but not an invasion, perhaps to downplay it. the kremlin trying to keep calm and carry on. for the last two and a half years, the message from the kremlin has been that the special military operation, russia's war in ukraine, has been going according to plan. this week's extraordinary events in southern russia suggest otherwise. even one of russia's most pro—kremlin newspapers admitted today that the ukrainian assault represented a strong move by president zelensky and that it was having painful consequences for russia. it's unclear how many ukrainian soldiers attacked and how they got through. so, what happened, like what,

there was no border patrol? how could these thousands, obviously thousands of troops, could get through? and so questions will be asked. but we also know that putin is very good at deflating attention from his mistakes or russia's mistakes into something else. and that is what i am going to see, i think we are going to see in the nearfuture. now russia is bringing in reinforcements to the kursk region. russian military chiefs have promised their president that they will restore control. steve rosenberg, bbc news, moscow. meanwhile inside ukraine, emergency services say a russian missile strike on a supermarket in the eastern donetsk region killed 1a people and wounded at least a0 others. james waterhouse reports from kyiv. in this part of ukraine, russia is advancing and with every mile they do, the more common strikes like this become.

once again, a missile hits a hub of civilisation, a supermarket where people were doing a daily or weekly shop. "we're still searching the area," says pavlo, a police officer. "we're trying to find out if anyone else could still "be under the rubble. "anyone." translation: russia always knows - where it hits with its missiles. and this is deliberate and targeted russian terror. scenes like this have been replicated before, but in times of a full scale invasion, it's not clear whether this is a response to ukraine's cross—border assault. here, it's hoped a counteroffensive like no other might bring respite. but optimism is hard to come by when this is a reality. james waterhouse, bbc news, kyiv. for more, i spoke to bill taylor, us ambassador to ukraine from 2006 to 2010. i want to start with the ukrainian incursion into russian territory,

the reports we see is they moved fairly deep into russian territory. what do you make of this incursion that is now in its fourth day? the fourth day, and it was a big surprise for the russians. how the ukrainians were able to achieve the surprise will be one of the big stories. you have reported they did not see it coming, they scrambled, vladimir putin was shocked and calling his people together. the surprise the ukrainians achieved will help them with this assault, this counteroffensive against the russians. they could go deep into russia and make it clear that they can win this war. that would be my question, what do you think the aim of this incursion is? is there a strategic aim or to send a message? i think it is both. strategic aim and a message being sent.

the message is "we can win this war," the ukrainians, "we can attack into russia, we can reach their lines, "we can counter them." what they try to send reinforcements, and the ukrainians attack the reinforcements on the way in there is a strong message there, the strategic message though is that the ukrainians will tell the russians with this invasion, this cross—border operation, they can't win. they can't win, levels that they cannot wait out, they have to continue the fight. the europeans will continue support. the americans will continue to support. the message is vladimir putin will have to look for a way out. looking at what is happening on the ground in russia, the ukrainians are using donated us and german weapons. what do you think the reaction and retaliation will be from vladimir putin who was clearly surprised by the attack? he will shoot what he did today, shoot missiles

at supermarkets, at schools and hospitals. vladimir putin attacks, the russian attack civilian targets, and that is what he will continue to do. he cannot win on the battlefield, that was made clear to him, all he can do is shoot at civilian targets. until now we have seen, despite the efforts from the west to supply weapons, the ukrainians have not been able to take significant territory in the last year, so the question will be can ukrainians hold this line in russia and also continue to fight along the battlefield lines in ukraine as well? that is the right question, exactly the right question, the other thing going on, to keep your eye on, is what is going on the southern part of ukraine where the ukrainians are making it difficult for the russians to stay in the crimea, the southern part of ukraine. they have occupied crimea since 2014 and now the attacks facilitated by weapons

that we have given them, the americans, are making it very difficult for the russians to stay there, both in the north and the south, they are taking initiative. looking at kursk, this fighting is edging gradually towards a nuclear power plant, something that mirrors what we have seen in ukraine with fighting in the past as well. are you worried about this spiralling out of control? not worried but i do think it is important that both sides respect the nuclear power plants, the russians in zaporizhzhia and the ukrainians, both sides need to respect that this is dangerous to be having military operations around nuclear power plants. looking at the us response, they have supported ukraine using weapons in russian territory where attacks have been launched from, as a way for ukraine to regain the ground. do you think there is perhaps concern here in washington over the prospect of us weapons

being used in russia? apparently not. even today they announced a large new package, some 3 million, 1.55 rounds so the americans have demonstrated their support for ukraine even today. there do not seem to be any qualms about the ukrainians attacking. the israeli military confirmed on friday that it killed a senior hamas official in the southern lebanese coastal city of sidon. military officials accused the official — samer al—hajj — of being �*responsible for the recruitment and training' of hamas fighters. the attack comes amid heightened tension in the region after iran vowed a response agasint israel after the killing of hamas leader ismail haniyeh in tehran last week. israel has not commented on that attack. israel will send a delegation to a new round of talks next week on a possible ceasefire deal with hamas that would also see remaining hostages released. hamas hasn't responded yet.

medics at the hospital said a wave of israeli air strikes killed at least 21 palestinians. evacuation orders triggered an exodus of palestinians from the eastern districts where many had just returned less than two weeks ago. the un agency said on friday that an estimated 60,000 - 70,000 friday that an estimated 60,000 — 70,000 people have been forced to flee khan younis since thursday. it is designated as a humanitarian zone but it has already been overcrowded by displaced families from across gaza. it is also in the target of israeli strikes most recently in july when israeli strikes most recently injuly when at israeli strikes most recently in july when at least israeli strikes most recently injuly when at least 90 palestinians were killed in a displacement camp. israel said that rate target of the chiefly highly 7 october attacks. earlier caitriona perry spoke with the chief humanitarian officer who was in central gaza. the situation is nothing

what we have ever seen before as humanitarians. yesterday we were driving through the evacuation order when people in eastern parts of khan younis were asked to evacuate at short notice one more time, and it was almost surreal, absolutely heartbreaking. hundreds of people walking with whatever they had with plastic bags, garbage bags. and sometimes i looked at a family and i was like something is not quite right, why is this dad walking with three children, where is the mum, is she here or already gone? then you see the elderly, i remember seeing a 2.5—year—old girl, walking with a baby carrier — maybe it was her own, elderly and disabled people, mattresses, small children carrying much more than their body weight. a lot had no shoes. children are wearing adult shoes. i learned today that

shoes are not in supply. the weather was so hot, everybody was sweating. and i looked at the faces of these children — they are not able to open their eyes because the sun is so strong. it was like a flower that we have left out in the open without any water to prevent — or protected from the sun. i kept thinking when did they last eat? where will they sleep tonight? how many times have we done this before? when they go to sleep, what will be their last image in front of their eyes? there was an absolute sense of exhaustion, fatigue and helplessness. we saw the humanitarian needs are hugely massive, and as a humanitarian this is not the first conflict zone i have seen. but absolutely this is one of the most worst. speaking of the evacuation orders that came for khan younis and many other parts of gaza,

where are people able to move to? where can they move? absolutely, this is the question which was on everybody�*s lips. they ask us to evacuate, but to where? mostly we saw people setting up tents, informal temporary shelters, groups of people. we saw some of them today, one was what they call a fallout shelter where there was about 50 families, another one with 600 or 700 tents — it was hugely overcrowded. we drove around and walked around the coastline and the entire coastline, maybe 10—15 kilometres, rows and rows of tents and plastic and on the beach by the sea, the weather is not only hot but very humid. a lot of people said it is practically impossible to be in the tent during the day. we heard of children having

so much skin disease because of the heat and humidity in the sand and the inability to get treatment or even to wash properly. people are just in hugely crowded conditions, and the incinerators are not working, so garbage is a huge issue. the frequency and the diversity of the tide which people have is extremely limited. that is all we have time for. stay with us here on bbc news. hello there. heat and humidity is set to build as we go through the weekend, but we do need to caveat that with saturday, there is going to be quite a lot of cloud around for most of us. but it will turn increasingly very warm and very humid from sunday onwards. let's take a look at what's happening, then. this weather front will bring more cloud on saturday into south west england and wales, and with isobars quite tightly

packed together further north, that's going to feed in plenty of showers, particularly from west to east across scotland throughout the day. southern scotland, northern ireland keeping some sunshine. england and wales, quite a lot of cloud feeding in. at times, there'll be some light, drizzly rain and poor visibility through the irish sea coast there. top temperatures, though, 2a degrees. that's still 75 fahrenheit. but as we move out of saturday and into sunday, this area of low pressure is going to move in and allow the winds to change to a southerly direction. and that means we're going to tap into some very hot weather that's taking place across the mediterranean at the moment. so early morning cloud will break up quite quickly. a lot of dry, settled, sunny weather right across the country on sunday. increasingly hot, increasingly humid. this weather front threatening to the northwest, but it will stay away during the daylight hours. 16—23 degrees likely in scotland. highest values, though, of 28 — 82 fahrenheit — in the southeast. that will lead to a very humid night to come, and on monday, the heat is likely to peak.

we could see some record—breaking heat in bordeaux if we get temperatures in excess of 41 degrees. but for the southeast, we're likely to see temperatures peaking somewhere around 32—33 degrees. at the same time, further north, that weather front moves in, and with that heat and humidity coupled with that front, we are likely to see some sharp, thundery downpours. really quite torrential, heavy rain for a time. that will freshen the story up further north, but we've still got that heat and humidity clinging on in the south east of england. 0ne low eases away, another is likely to move in, again bringing some unsettled weather. not for all of us, but certainly a fresher feel as we go through the week ahead. there will continue to be some lengthy spells of sunshine, particularly across southern england. showers or longer spells of rain likely further north.
