assembling over climate change. hello, and welcome to bbc news. the coronavirus has over 2000 infected, with 56 killed. i'm a correspondent has been to hubei province in china. 0nly only after a temperature scan can you pass these checkpoints. the u nwell you pass these checkpoints. the unwell and not allowed to travel.

wrote that the infection zone have been closed. so basically, it is the border that way. the police have told us that you can drive in but you cannot drive out. seems that the whole province where the corona violence first broke out is now going to be locked down. instead of lunar new year celebrations, people are in survival mode. 0n 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. mcdonell reporting there, we will return to this story as we get more.

more than 1000 people have been injured in the east of turkey. 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. 0thers, though, are out on the streets. richard galpin, bbc news. let's get some of the day's other news 110w. let's get some of the day's other news now. israel has launched their strokes on the gaza strip. the israeli air force said it was targeting areas being used by hamas.

at least three people have been killed in iraq mark during clashes between security forces and anti—government protesters. dozens we re anti—government protesters. dozens were injured in the violence in baghdad. the venezuelan opposition leader one guaido is in spain as pa rt leader one guaido is in spain as part of a european tour, aimed at strengthening support for his campaign to remove nicolas maduro from power. mr madero has been recognised as venezuela's interim resident, countries including spain. at least 31 people have been killed and thousands displaced after a week of heavy rains and floods in madagascar. 15 the people does marketing people are reported missing —— 15 people have been reported missing. president trump's lawyers have begun setting out his

defence at his impeachment trial in the us and it was that mr trumpism accused of abusing his power and obstructing congress. the president because i could said his accusers had no evidence and that the real motive was to undermine mr trump agreed election campaign. 0ur respondent chris buckler is in washington. donald trump's lawyers did try to counter some of the arguments made by the democrats‘ impeachment team, but mainly they try to set a bigger picture argument, that the democrats weren't really concerned with abuse of power or that mr trump had not been behaving inappropriately in office was not instead they claim they were more concerned with overturning the vote that put him in that office in the first place. they are asking you to tear up all of the ballots across this country on your own initiative, take that decision away from the american people. what i have learned from all my

years in politics and all my years in life, if you're right and you keep fighting for the truth, you will prevail. we would be derelict in our responsibility if we didn't fight for the truth. well, you might get a sense from that 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, a very confident mr trump was encouraging people to tune into the televised proceedings and he was tweeting in not—very—flattering terms and in ways that his lawyers would not have gotten away with in congress about his political opponents. he will continue to make arguments on monday, and you can expect those arguments to be perhaps a little bit more pointed, political and nastier. the principles has that he would like to make an official visit to iran. he described the uranium people as remarkable and said the

country had contributed much to human knowledge and culture. iran's ties with britain have been strained recently by the stomach republic's imprisonment of 19 is accardi radcliffe. a look into the future, the world's largest when engine jetliner, the boeing 777x completes its maiden flight. —— twin engine. the shuttle challenger exploded soon after lift—off. there were seven astronauts on board, one of them a woman school teacher. all of them are believed to have been killed. by the evening, tahrir square the heart of official cairo was in the hands of the demonstrators. they were using the word revolution. the earthquake brought down buildings in seconds. tonight, the search for any survivors has an increasing desperation about it

as the hours passed. the government is a family in control of the entire republic of uganda. survivors of auschwitz have been commemorating the 40th anniversary of the liberation. they toured the crematorium and the gas chambers and relived their horrifying experiences. this is bbc news, the latest headlines: china has ordered a ban on organised tour groups, as a deadly new strain of coronavirus continues to spread. viruses claimed 56 lives. —— the virus has claimed 56 lives. president trump's lawyers have begun the case for the defence at his impeachment trial. they say he did nothing wrong.

jennifer not —— nuzzo has worked us through what she knows 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. from your view, purely scientific and medical point of view, do lockdowns like the kind of lockdowns china is imposing, do they work? 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. a year ayearago, a a year ago, a dam above a mining village collapsed, killing 270 people. it was one of the worst ever

industrial disasters in brazil, 16 people from the mining company vale along with its owner and auditor have been charged with murder. but few people there believe justice will be done. our south america corresponded katie watson has returned to the town to see how the community is coming to terms with the tragedy. 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.

there will‘s largest twin—engine jetliner the boeing triple seven x has completed its maiden flight. the passenger jet is has completed its maiden flight. the passengerjet is starting a year of testing and is due to enter international service next year. alan will be hoping to make a success of its latest aircraft after the company was engulfed in crisis after being forced to ground its fleet of 737 max plans after two fatal crashes. 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. 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 further and carry a better load of people. boeing has a new boss, dave calhoun. he has only been in thejob 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 and that 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 in the previous ceo

and now dave calhoun. the broadcaster and naturalist david attenborough has addressed the first uk citizens assembly on climate change, warning members they may not get swift action from politicians. 110 people from all walks of life have been asked to leave over four weekends to come up with ideas about how the country should meet its target of net zero emissions by 2050. he thanked the audience were taking climate change seriously. so the fact that you are here is extremely important because it shows that you could put pressure on your members of parliament to take this seriously. so that's — your very existence here means members of parliament are taking this seriously. that is point number one. point number two is that i am perpetually asked by people, "what is it that i can do to help with the problems?" i suspect that one way or another, during your deliberations,

all kinds of solutions to that particular question will occur to you, and that they will be spreading through the community. so i truly think because i believe that the question we are facing is of utmost importance, i truly think that the fact that you have given up time to come here and take this seriously is of the greatest importance, and the rest of the people in this country ought to be extremely grateful to you indeed. sir david attenborough. thousands of people have been taking part in rallies across australia to oppose the annual celebration of australia day. the new voices adding the concern over climate change and the ongoing bushfires sweeping the country. the public holiday has caused controversy for years. critics argue it celebrates what many indigenous aborigines is considered the invasion of their

homeland by british colonisers. however some protesters say the marchers are not meant to be confrontational. in 1996, the democratic republic of the congo, then known as ina, was in the grip ofa then known as ina, was in the grip of a violent civil the conflict reached the remote area the north—east of the country, an area with enormous biodiversity and mitch in rentals like diamonds. dedicated conservationist hitting the forest from armed groups to try to protect the forest‘s plants and animals, despite repeated threats to his life. he spoke to a witness history team. i grew igrew up i grew up in

madonna has cancelled the first london show of her madame x tour, saying she has to rest because of an injury. she was due to begin a run of 15 london performances at the palladium on monday and it comes after she cancelled a show in lisbon earlier this week, posting on social media to tell fans she was deeply sorry, adding" as you all know i have had injuries that have plagued me since the beginning of the tour but i must always listen to my body and my health first" and it will ta ke and my health first" and it will take awhile to get back the groove.

iamon take awhile to get back the groove. i am on twitter atjames bbc 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. 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 at times, it does look milder. 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 at times, it does look milder.
