transmission is the only plausible assembly for caring about the impact to explanation for the of climate change. passion and drama scale of the epidemic. it is known to have killed at least 56 people. lawyers representing donald trump at the australian open as the in his impeachment trial say 15—year—old sensation puts on an that the president has amazing show for a place in the done nothing wrong. they say the democrats in the senate have not shown he abused his power and were attempting to remove quarter—finals. him from office before the next election. the turkish president has met rescue workers searching for survivors of the earthquake on friday. 29 people are known to have died china's president has warned the and over 1,400 have been injured. residents have been warned to not country faces a great situation as return to damaged buildings the debt the coronavirus spreads because of possible after—shocks. those are the headlines. with increasing speed. the pirate is known to havejill ellis 56 people with the most 2000 infected. our correspondent stephen mcdonald has been to central china. the approaches to hubei province are like scenes from an apocalyptic movie. only after a temperature scan can you pass these checkpoints. the unwell are not

allowed to travel. what's more, the lockdown is spreading. roads out of the infection zone are being closed. so, basically, that's the border that way. the police have told us that you can drive in, but we can't drive out, so it seems that this whole province where the coronavirus first broke out is now going to be locked down. we cross the border and drive through ghost towns. instead of lunar new year celebrations, people are in survival mode. on the first day of the year of the rat, all these shops are closed. there is pretty much nobody on the street here. i mean, this isjust one of the towns you come across when you first enter the province, and peoplejust don't know for how long it's

going to be like this, for how long they have to stay indoors or risk being infected with this potentially deadly coronavirus, which causes pneumonia. hospitals here have been flooded with patients. there are thousands who are unwell, but are not sure if their symptoms mean it's the coronavirus. one man inside this hospital speaks to us from his hospital bed. he said he hasn't been told if he's contracted the potentially deadly virus, but he's worried he could catch it anyway from others in his ward. i wish him a speedy recovery, and the police arrive as if on cue. they won't confirm if a province—wide lockdown of 60 million people is about to start, but local officials want us to leave. so, as night falls, they escort us back across the border.

we have heard official at thejohns hopkins centre for security, she expands on about the virus. well, we know that it is a respiratory virus, so it's spread by respiratory symptoms, people coughing and putting virus into the air. but what we're still trying to understand is how quickly is it spreading between people? so we don't know — for example, if i had a virus and i coughed on someone, would that be enough to transmit the virus, and so on. right, exactly, and if you were sick and you are going about your day, how many people you would you make sick? and how do we find out that information? well, unfortunately it is slow and steady work that requires trying to understand cases, identifying their contacts and trying to piece together who may have gotten sick from whom. to some extent we are also looking at the genetic analysis of the virus, which can potentially link cases together. but right now, i think there are still a lot of questions. as of a week ago, there were even

still questions about whether or not people could just transmit it to each other in a sustained fashion. i think now we're starting to learn that that is probably the case, and that perhaps it's more than just people transmitting to their individual family members. a study published in the lancet medicaljournal has raised concerns that people might be transmitting the virus before they give any evidence of symptoms. what is your analysis of that? yes, so i haven't actually seen compelling evidence of that. yes, there was one of the cases they found the virus from the case, but the case hadn't yet developed symptoms, so that made people sort of wonder if it's possible for asymptomatic spread. that would be unusual for coronaviruses, and i haven't seen any compelling evidence that people are spreading the virus before they develop symptoms. one of the things that people have really been lamenting the absence of individual, you know, data on individual cases, to understand what day

they became ill. when we map the number of cases that became ill on any given day, it gives us a sense of how fast the situation may be growing, or not. so we don't have that. from your view, purely scientific and medical point of view, do lockdowns like the kind of lockdowns china is imposing, do they work? so i am deeply worried about these approaches. i think we have absolutely no evidence that this will work, and in fact we have lots of evidence to suggest it may actually backfire. the scenario that i worry about, which i think is highly likely, is that people know that these measures are coming. they have heard of these measures. they may simply decide they don't want to be around when they happen, that it's not a good situation to be in, and that they may flee potentially before the restrictions are put into place. so i am really worried about the potential to scatter cases to geographies that we don't know about. i am also worried about these really heavy—handed measures, you know, that the police involvement, that this stigmatises the disease, such that people who become ill may not want to report the fact that they are ill. and that makes it very, very difficult, because i think

the most effective measure we can employ at this point is to promptly identify cases and isolate them, so they can't affect others. a major rescue event is taking place in turkey where teams are working on freezing temperatures to free people trapped under buildings. more than a dozen people are known to have been injured and just a warning, this contain some distressing images. she is just five years old, and covered in blood, but this girl is now safe. the rescue team pulling her out from under the smashed blocks of concrete and other debris brought down by the earthquake. and she is just one of more than a0 people to have been rescued here so far. for the rescue teams, speed is now essential to save lives in freezing temperatures.

this emergency worker using a mobile phone to speak to a family trapped underneath the debris, telling them they must keep awake. the powerful earthquake struck this eastern region of the country last night, causing hundreds of casualties as buildings collapsed. in the light of morning, the extent of damage was revealed, this just one of 30 buildings to have been brought down. and hundreds of aftershocks over the past 2a hours have added to the fear in this earthquake—prone region. some of the homeless have now found shelter, as the temperature at night drops to —10 degrees. others, though, are out on the streets. richard galpin, bbc news.

let's get some of the days of the news now. israel has launched air strikes against the gaza strip. the epos as it was targeting site used by the palestinians in response to recent launches of incendiary balloons. they said the fundable balloons. they said the fundable balloons are part of a new offensive against israel for failing to honour an unofficial truce. at least three people have been killed in egg ——in a rock during clashes between security forces and anti—government protesters. dozens were injured in baghdad. the venezuelan opposition leader is in spain as part of the tour of european countries and strengthening support for his campaign to move his adversary from power. he defied the travel ban travel to europe has been recognised as basilar's interim leader. his bid

for in that —— his bid for elections has failed to unseat the current president. dozens are disposed of the week of heavy rains in madagascar. 15 people are reported missing and according to officials their disputes or triggers is from mind and crock has been damaged. —— farmland and cops have been damaged. president trump's lawyers have begun building his defence. he is accused of abusing his power and obstructing conscious. his accusers had no evidence in the real motive was to undermine mr trump's relation campaign. chris butler is in washington. as the future of his presidency has been under debate, president trump has been to davos to meet world leaders, to florida to speak to supporters, and ignored other events in washington to attend a pro—life rally. they were concerned he hadn't been behaving properly enough. they were more concerned about overturning the

boat that put them in that office in the first place. they're asking you to tearup all of the first place. they're asking you to tear up all of the ballots across this country. on our own initiative. take the decision away from the american people. what i've learned to all my years in politics and all my years in life, if you are right and you keep fighting for the truth, you will prevail. we would be derelict in our responsibility if we didn't. you make it a sense that the democrats know they have no chance of removing president trump from office, they simply don't have the numbers in the senate but a couple of miles away in the white house are very confident mr trump was encouraging people to tune into the televised proceedings and he was treating and not very flattering terms and in certain ways that his lawyers would not have got away with in congress about his political opponents. his team will continue to make their arguments on monday and you expect those arguments become a

little pointed, little more political and perhaps looking nasty. chris butler in washington. the prince of wales has said he would like to make an official visit to be east. prince charles made the comments during an interview with us in the way, he explained the much to human knowledge and culture, the ties with britain... a year ago, a dam above a mining village collapsed in brazil, engulfed in the community and killing 270 people. 16 people from the mining company along with the mine's owner in order to have been charged with murder. but few people believe justice will be done. south america corresponded has returned to the town.

the name of every one of the 270 victims was read out like a register, theirfamilies answering for them. a town that once thrived on mining now devastated by it. when the dam broke last year, the toxic sludge that came crashing down the valley destroyed everything in its wake. houses, hotels, farmland and forests. and this is what's left behind. 10 million cubic metres of mud that needs to be cleaned up. firefighters are still looking for 11 people who are missing. today's commemorations brought together communities from all over the region. nobody here is untouched by this tragedy. this is as much a remembrance for those who died as it is a protest for those who are living.

brumadinho was broken by what happened last year and people want justice. "my nephew wants to kill himself every day," says claudia, who lost her brother—in—law. "the mud that hit this city also hit our hearts." i ask her what she thinks about the mining company. "all vale is is destruction and death. theyjust cared about profit. nothing has changed this year, apart from our pain. it's only got worse." murder charges brought against the companies involved go right to the very top. vale's former boss is among the accused. translation: vale and its workers knew the risky situation of the dam and they had demanded action, but nothing was done. today was a day for remembrance. tomorrow, they continue theirfight forjustice. katy watson, bbc news in brumadinho. stay with us, still to come: look into the future, the world ‘s largest twin minor engine boeing

beat the defending champion naomi osaka. it underlines a reputation as a grand slam champion in the making. you might remember when she was out of court she was asked had she met rod lavey yet and she said she would love to have a selfie with him and she hadn't met him. and rod lavey junior said he would do that. she would hope to make it through the final. she has plenty of work to do at the moment. let's have a word out some of the australian fans. it is an incredible atmosphere. very different to wimbledon, which is a more serene and traditional atmosphere. this is a cool and relaxed environment. and as its australia day we have some australia fans. to be honest with you, we could not let the world ‘s not see this fantastic array of headwear. where did you picked pick this up from? the reject shop. big celebrations today, australia day.

let's not forget that ash barty, the world number one australian hopes on her shoulders this year. can't wait to watch. do you think she can do it this year? i think she canne. go aussies. we were just talking about coco gough machine generated so much excitement for someone so young, drifting, knocking up the defending champion. it is quite some story emerging there with her.|j champion. it is quite some story emerging there with her. i dare say so. emerging there with her. i dare say so. she sounds pretty good. you love her as much as ash barty? yeah, sure... of course not. i presume you will be seeing ash barty later on. absolutely. it will be a great match. a beautiful day, nice and sunny. it is a lovely atmosphere. it is quite unique this atmosphere at melbourne park, partly thanks to you lot. you lovely aussies generating this great atmosphere. thank you very much. it is good to be here. it will be a great day. i have to ask

about nick kyrgios as well. he is obviously another australian hopeful. he is a controversial character at times. do the australian public love him or hate him? what is the relationship with him? what is the relationship with him? i like, i don't mind him. he seems like a pretty good dude and he likes to play tennis as well. he plays some pretty decent tennis. great to chat to you. thank you very much. you haven't got a spare one in that bag, do you? no, sorry. thank you very much indeed. do you want to p0p you very much indeed. do you want to pop that on? there we go. put that on there. there we go, james. i am all set for the ash barty match. two things, number one, bring some back for us. and to answer your question, andi for us. and to answer your question, and i was 15 oh was pretending to be and i was 15 oh was pretending to be a newsreader. it didn't work out that way. fantastic to join us. they

have lost you. good luck to both players. the world's largest when engine jetliner the boeing 777 x has completed its maiden folate. it is starting a year of testing and is due to anti— international service next year. boeing will be hoping to make a success of its latest aircraft after the company was engulfed in crisis after it was forced to ground its fleet of 737 max planes up to two fatal disasters. they asked james if the new plan will help boeing to rehabilitate its image following the recent disasters. the 777x aircraft is almost a fresh beginning for them. they have been plagued by basically financial disaster here over the last year with the 737 max aircraft, and we know that production has now been stalled. so the 777x aircraft is almost a fresh beginning, where they can prove to the public, they can prove to customers that they have a viable product that product is able to fly, it's able to be delivered, and there are no issues with that aircraft.

so while they continue to focus on the 737 max, the 777x is definitely something that is going to be put into the spotlight, and hopefully be viewed positively and have a positive light on the 737 max. does boeing face extra scrutiny over safety, given what happened to the 737 max? yes, most certainly — and that's notjust what the 737 max aircraft, that's also with the 777x and every other line of their 737 line. and every other aircraft they have, they are featuring definitely a safety scrutiny. regulators are going to be looking at it with a fine—toothed comb. this particular plane, the 777x, who is going to buy it? chuckles. so, aircraft like this are definitely good for folks that do not want an a380. so the a380 is a huge aircraft, it would accommodate a lot of passengers, but what is happening is that demand to certain locations is falling and also, airlines want to increase frequencies to certain destinations, and they can't do that with the a380.

the a380 is like a beluga whale. it can accommodate so many passengers and so, many airlines may run one frequency a day, two frequencies a day to a certain destination. now they can run more with the 777x at a much more fuel—efficient rate, and that plane is able to go farther and carry a better load of people. boeing has a new boss, dave calhoun. he has only been in thejob, what, a couple of weeks? how is he making his mark? he's been much more communicative to both the media, journalists, customers. he is really taking this from a head—on approach, admitting fault, saying there was a mistake, there were many issues with the 737 max. he's not hiding from it. he's coming right out into the forefront here and sharing those issues and promising that things are going to be fixed. so we are almost seeing basically a 180 degree of communication

here between the previous ceo and now dave calhoun. i wanted to take you to delhi, because india is marking its republic day and we can show you some live pictures from the celebrations there. they began in a reasonably sombre mood a little earlier, with prime minister narendra modi laying a wreath. there he is residing over those ceremonies. he has a guest of honour, you may not be able to see him in those pictures as he watches the fleet, the guest of honour is the fleet, the guest of honour is the president of brazil, esther bolsonaro, who has come over for the occasion, an indication of solidarity between brazil and india —— mr bolsonaro. it marks a day the constitution came into effect. the constitution came into effect. the constitution and the nature of india are at the heart of the debate of mr modi's government. critics accused him of trying to change the nature of india. he says he is simply

following the mandate given to him by voters. we will continue to follow the story. please stay with bbc world news. hello. sunny skies are on the way back, but it's going to feel colder. there will be showers and it will be windy. it all follows a spell of rain on sunday, low pressure making things very changeable again after high pressure, which may have kept us dry but certainly recently, it has given us these grey, gloomy skies, and it did again on saturday. sunday starts without a frost. dry across the east, except for the odd shower. wet in the west. the rain from this weather front moving west to east across the uk on sunday. behind that wet weather, we're in the blue. this is the colder air coming in. within that, there will be sunny skies to start the new week, also showers — cold enough for those to be wintry in places,

as we will see in a moment. let's follow the progress of sunday's rain. quickly out of northern ireland, pushing through scotland in the morning. the sunshine comes after the rain. it should clear northern england, wales, the west of england into the afternoon. turns a bit brighter there. still there to end the afternoon across east anglia and south—west england. wintry on hills in scotland. a windy day. with the rain, it turns colder, so that combined with the wind will make a chillier feeling to things during sunday afternoon, despite the fact the sunshine reappears in places. with that cold, our showers move east on sunday night. we focus on northern ireland, northern england and scotland, because here, some of those showers will fall as snow on hills — relatively modest hills and quite low levels across some parts of scotland. a few centimetres in places possible. ice on untreated services going into monday morning, so don't get caught out by that. monday, yes, there is some sunshine around. the eastern spots will stay dry. showers pushing into the south and west will be heavy, possibly thundery, maybe some hail. wintry across northern hills. a bright but blustery day for many of us. again, that wind is a factor in making for a colderfeeling to things compared to recently. low pressure stays in charge of our weather for the rest of the week, initially anchored towards the north—west here, and bringing in the showers,

especially towards the south and the west of the uk. so the week will start with a colder feeling to things compared to recently. some frosty nights around as well. there will be some sunshine, but we have noticed some showers, cold enough for some of these to be wintry, especially across northern hills. windy through the week with low pressure close by but by the end of the week, it will start to feel different again and temperatures are on the up. unsettled, yes, dominated by low pressure and changeable, but later in the week, although it's still windy and wet 00:28:24,677 --> 4294966103:13:29,430 at times, it does look milder.
