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. 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. a major rescue operation is continuing in eastern turkey where an earthquake has killed dozens of people. teams are working and freezing temperatures to reach the

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 days other news now. israel has launched air strikes against the gaza strip. the israeli air force as it was targeting sites used by hummus in response to recent launches of sentry balloons. a must, which governs gaza, sentry balloons. a must, which governs gaza , says sentry balloons. a must, which governs gaza, says the flammable balloons were part of a new

tried to set out a bigger picture argument. donald trump's lawyers did try to counter some of the arguments made by the democrats‘ impeachment team, but mainly they try to set out 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 prince of wales has said he would like to make an official visit to iran and he prayed for a resolution to conflicts in the middle east. he made the comments during an interview with a british newspaper time to mark his trip to the middle east which began earlier this week. he described the iranian people as remarkable and so the country contributed much to human knowledge and culture. lahri's tries with britain have been strained recently by the imprisonment of a british iranian citizen. stay with us on british iranian citizen. stay with us on bbc news. still to come... a look into the future. the world's largest twin—engine jetliner, the boeing triple seven x completes its

they toured the crematorium and the gas chambers and relived the horrifying experiences. this is bbc world news. the latest headlines. china has ordered a ban on organised tour groups as the deadly coronavirus kinds at least 65 lives and continues to spread. president trump ‘s lawyers have begun the case for the defence at his impeachment trial. they say he did nothing wrong. more now on our main story, the coronavirus. doctor jennifer is a senior scholar and epidemiologist at the johns jennifer is a senior scholar and epidemiologist at thejohns hopkins centre. she explained what is known about the coronavirus. we know that it isa about the coronavirus. we know that it is a respiratory virus so it spreads through respiratory symptoms, people coughing and putting virus into the air. but what

we are 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? exactly. and if you were sick and you are going about your day, how many people would you make sick? and how do we find out that information? unfortunately it is slow and steady work that requires trying to understand cases, identifying contacts and trying to piece together who have gotten sick from whom. to some extent we also look at the genetic analysis of the virus which could potentially link cases together but right now i think there are still many questions and even questions about whether or not people could just transmit it to each other in a sustained fashion. i think now we are starting to learn that that is probably the case and perhaps it is more thanjust that that is probably the case and perhaps it is more than just people transmitting to their individual family members. a study published in

the lancet medical journal family members. a study published in the lancet medicaljournal has raised concerns that people may be transmitting the virus before they give any evidence of symptoms. what is your analysis of that?” give any evidence of symptoms. what is your analysis of that? i have not actually seen compelling evidence of that, yes there was one case where they found the virus from the case but the case had not yet developed symptoms so that made people wonder if it is possible for it to a symptomatically spread. that would be unusual for symptomatically spread. that would be unusualfor a symptomatically spread. that would be unusual for a coronavirus and i have not seen any compelling evidence to suggest that people spread the virus before they develop symptoms. 0ne spread the virus before they develop symptoms. one thing that people have been lamenting is the absence of individual, 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 a scientific and medical point of view, do lockdowns like

those china is imposing work? we have no evidence that this will work and we have a lot of evidence to suggest it may actually backfire. the scenario i worry about which i think is highly likely is that people know that these measures are coming, they heard of these measures, they may simply decide they do not want to be around when they do not want to be around when they happen and it is not a good situation to be in and they may flee before the restrictions are put into place. so i am worried about the potential to scatter cases to geographies we do not know about.|j geographies we do not know about.” would like to take you to delhi now for some live pictures because in india at the moment it is republic day and that you can see the prime minister and the renter are he has been taking part in commemorations at india eight, one of the commemorations he will be involved in as the laying of a reef. republic day or honours the date in which the constitution of india came into effect. it was on january 20 619. 0ne effect. it was on january 20 619. one of the guest of honour at this

particular ceremony is the brazilian president. this comes at a sensitive time in india given the fact that the prime minister, who you see there, critics accused him of wanting to change the foundation of the state of india following his re—election in 2019, particularly critics are angry at his attempts to alter and offer asylum to only non— muslim members of nato countries. he is merely claiming to carry out the mandate of the people. now, one year ago a mandate of the people. now, one year agoa dam mandate of the people. now, one year ago a dam above a mining village collapsed in brazil, engulfing the community and killing 270 people. it was one of the worst ever industrial disasters in the country. 16 people from the mining company mcphail, have been ordered and charged with murder but few people there believe justice has been done to —— vale. we have returned to the community to

see how the community has come 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. the world'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 one 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 it was forced to grant it fleet of 737 max plains after two fatal air disasters. we spoke to an aircraft blogger. 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. sir david attenborough the naturalist and broadcaster has addressed the first uk citizens climate assembly. he warned members they may not get swift action from

politicians. 110 people have been asked to meet over four weekends to come up with ideas about how the country should meet its target of net zero emissions by 2020. the naturalist thanked them for 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 i'm 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. in 1996 the democratic republic of the congo, then known as zaire, in the grip of a violent civil war and conflict reached a remote forest in the north—east of the country, an area with enormous biodiversity and rich in minerals like diamonds. a dedicated conservationist hit in the forest from armed groups to try to protect the plants and animals, despite repeated threats to his life. he spoke to the witness team.

file: almost a quarter of a million people have fled refugee camps in eastern zaire because of fierce fighting in the region. the un says it has begun an evacuation of humanitarian staff from eastern zaire.

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.

this is bbc news. the headlines. china's presidents is spread of the new strain of coronavirus is exhilarating and putting the country ina grave exhilarating and putting the country in a grave situation. experts say human to human transmission is the only plausible to explanation for the scale of the epidemic. it is known to have killed at least 56 people. lawyers representing donald trump in his impeachment trial say the president has done nothing wrong. they say the democrats in the senate have not shown he abused his power and were attempting to remove 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 and over 1a00 have been injured. residents have been warned to not return to damaged buildings because of possible after—shocks. those are the
