Hello and welcome to world news today. Day four of Donald Trumps impeachment trial in the us senate has begun. Democrat prosecutors argue that the president should be removed from office for abuse of power and for obstructing congress. They say hes used Foreign Policy for his own personal, political gain. Mr trump has dismissed the trial as boring. In the past few hours, us media has reported a recording has emerged of the president apparently saying he wanted the ambassador to ukraine, marie yovanovitch, fired. One of the houses impeachment managers, adam schiff was asked his thoughts before todays session got underway. I dont have enough background to give you a response to it at this time but, plainly, if the president , at the urging of giuliani or parnas or fruman, if this is additional evidence of his involvement in that effort to smear her, it would certainly corroborate much of what we have heard, but im not in a position yet to analyse that, not having looked at it. The Senate Minority leader Chuck Schumer has been speaking making the case for witnesses to be allowed to give evidence. The bottom line we are seeking the truth at a momentous time in the american republic. It is on the shoulders of four republican senators tojoin us in demanding it. We have made the argument forcefully. The American People have made the argument forcefully that they want the truth. Will four republican senators, just four, rise to the occasion, do their duty to their constitution, to their country to seek the truth . Republican senator Lindsey Graham has hit back at democrats, claiming that if they wanted more witnesses, they should have allowed joe biden and his son hunter biden to be called during the house inquiry. The manager said there is not one piece of evidence to suggest that hunter biden did anything wrong in this record. And there never will be if you dont call any witnesses they tried to call hunter biden and People Associated with him, and they were shut out. I was pretty offended by the idea that there is a record here and there is not one shred of evidence that hunter biden did wrong, when you stop the house from calling hunter biden. So thats having your head in the sand. I asked our washington correspondent Gary Odonoghue about whats on the agenda today. What they are focusing on today is the second of the two articles of impeachment and that is the one that relates to what they call obstruction of congress, and that effectively is saying look, the president in the white house did not handle every hand over any documents and stayed in the way of people giving testimony and present prevented using witness is the one that and thats an impeachable offence in its own right. So they are making that case, they are going over a lot of the old ground in terms of the detail of ukrainian business in order to illustrate what was missing and what is missing from the narrative about that because of what they call obstruction of congress. So, that will go on for the rest of the day and then tomorrow at president s defends team will kick off their case, they have 24 will kick off their case, they have 2a hours to do that in the same way as democrats they. They will start at ten a m. , a bit earlier tomorrow morning, is not entirely clear that the defendants will use their entire 24 the defendants will use their entire 2a hours, they may go shorter. The defendants will use their entire 24 hours, they may go shorter. Is there any more detail on the recording which emerged which reportedly you can hear President Trump calling on the Us Ambassador to ukraine to be fired . No, nothing in any great detail about that at the moment, i think we have to be cautious about that at this stage. But the democrats believe that more and more things are coming out of this trial but remember they had this trial but remember they had this whole release of documents from a ukrainian businessman who they believed was working for the president plus plus press no lawyer, trying to in some ways kind of oust the Us Ambassador to ukraine, so that me all play into that so we will see what happens. Thousands of people have been marching in the streets of baghdad demanding that all us troops be expelled from iraq. The marchers chanted anti us slogans, and some carried effigies of President Trump. Around 5,000 us soldiers are in the country as part of the International Coalition against the Islamic State group. One of iraqs most powerful and influential shia clerics Moqtada Al Sadr had called for a Million People to join todays march close to the us embassy in the capital. 0ur middle east correspondent martin patience is in baghdad . If you control this street in iraq than you can rule the country. This was downtown baghdad today, supporters were out in force. This movement is the political and spiritual backbone of the country. And their message for the man in the white house was unmistakable. There isa white house was unmistakable. There is a carnival like atmosphere here that this is a serious political event. There is she a cleric as a man who can draw supporters out onto the street and with this march, he is showing his political hand, he wa nts all is showing his political hand, he wants all american voices to leave iraq. The us and the assassination of iran top military commander changed the dynamics here. Iraq now finds itself centre stage, caught in the struggle between the us and iran. Translation , the the struggle between the us and iran. Translation , the americans killed many of us, all of the explosions here are because of them, both america and iran has no place here. They should both be expelled. Translation he will use all the hermetic means available to him. But if the us still does not withdraw its troops from iraq, it will face the resistance. Today, the protest was peaceful, but it was a warning to america. The us troops must leave iraq or they may have another fight on their hands. A powerful earthquake has struck eastern turkey, killing four people and damaging buildings near the epicenter of the tremor. The quake shook the siv riss district in the province of elazig, at a shallow depth of 10 kilometres. Weve just received these pictures of rescue efforts underway in the area. The quake oocured in a remote and relatively sparsely populated region and it could take some time for authorities to find out the full extent of the damage. The Lunar New Year holiday has begun in china, but the festive spirit is being dampened by drastic measures to prevent the spread of the new virus that has killed 26 people, and infected over 800 more. But the World Health Organisation says its not a global problem yet, although cases have been confirmed across asia, in the united states, and as of the last few hours, in france. Stephen mcdonnell sent this report from beijing. You cant move around china at the moment without being aware of this crisis. Health screening is in place at transport hubs across the country. Public celebrations marking the Lunar New Year being cancelled and the inconvenience is considerable. At most, people are welcoming Decisive Action from the government. Translation china is a very strong country, it can definitely control the virus, also a vaccine will be developed, we are very confident. Translation typing this thing will go away in the near future, like sizing 2003. Now the governmentsjob is to prevent its spread, i think it will disappear by itself. In wuhan, hospitals are stressed to the limit. I had a fever and a cop so i am worried that i am infected. I dont know the results yet but i am concerned, and a bit nervous i have the virus. Wuhan is a very large city with a large population. The medical capacity of wuhan alone cannot withstand the outbreak of the virus. It needs the support of a whole country. The Chinese Government has any footage ofa Chinese Government has any footage of a new quarantine facility under construction at a frantic pace. They say it would be used to cope with an ever growing number of patients infected with the coronavirus. Chinas new years eve is much more quieter this year than it normally would be. In most cities, there are very few people on the streets, it seems a lot of people dont want to leave their homes for fear of catching the coronavirus. Instead of a mood of celebration its one of trepidation with many wondering just how bad this problem is going to become. The potentially deadly coronavirus is thought to have spread from animals into humans at a life Produce Market in the wuhan. Officials have all but locked down the city of ii officials have all but locked down the city of 11 Million People to try and slow the speed of the sickness spreading. If we all work as one, we can contain the virus in wuhan and export number cases from here. We can stop the virus from spreading nationwide. For many at this chinese new year, its pretty bleak, but if they can get through it without them oi they can get through it without them or their loved ones falling ill, they will be pretty happy. The bbcs africa editor and veteran war correspondent fergel keane has annouced he will be stepping down from his position, citing the effects of post Traumatic Stress disorder. Keane has reported from the frontlines for the bbc since the 1980s, gaining widespread recoginition for his coverage of the rwandan genocide in 1994. His posting have included some of the bloodiest conflicts of the past two deacdes, including iraq, ukraine and syria. In a statement a bbc spokesperson said he had been dealing with condition privately for several years, and is recieving professional medical advice. Bruce shapiro is a journalist and director of the dart center forjournalism and trauma, a think tank focusing on the psychological impact of reporting traumatic events. Thank you so much for talking to us here on bbc news. First of all, lets talk about for a goal because obviously he is a huge figure in their field of conflict reporting, so their field of conflict reporting, so this announcement by him has a big impact, doesnt it . Certainly, he isa big impact, doesnt it . Certainly, he is a hero ofjainism but as a special irony that someone who has done so much in his career to draw public attention to the real impact of yr and conflict and poverty on ordinary folks, now is one of those casualties of violence. It may not come as a surprise casualties of violence. It may not come as a surprise and yet it says something about the courage and the dedication of fergal keane and other correspondence to do this work knowing that there is the risk of occupational injury, occupational psychological injury which is just as real as the risk of being wounded oi as real as the risk of being wounded or killed. How did that you think oui or killed. How did that you think our understanding is of ptsd in relation to journalism and trauma, we talked about surgeries and ptsd, what about journalism 7 how we talked about surgeries and ptsd, what about journalism . How developed you think our understanding of that has become . Ten or 20 years ago, there was virtually no conversation, no one in history of psychology and no one in history of psychology and no one in the history of general exa m no one in the history of general exam until the late 90s had ever really bothered to think much about this. Over the course of the last 20 yea rs, this. Over the course of the last 20 years, there has been now whole Body Research around the world showing that genetics and not only were correspondents but generalists covering crime, generalists covering intimate partner violence, generalists covering all sorts of natural disasters that we are on the one hand a resilient tribe with an importantjob one hand a resilient tribe with an important job to do one hand a resilient tribe with an importantjob to do and the skills to do it and on the other hand, we do have the real risk of ptsd. Many news organisations now incorporate trauma awareness and incorporate generalists and peer support and other attempts to address what is a serious Occupational Health hazard and a serious cost to bearing witness. Very briefly, what is the best way do you think to help generalists to deal with, and to in some cases perhaps avoid being traumatised as much as they could be . Well, first of all, the leadership of generalists like fergal keane who have come forward and they have been others as well to talk about their own psychological injuries and the impact that their coverage has had, that has praised the way for a generation of younger reporters who are much more willing to co nfro nt reporters who are much more willing to confront these issues and feel less stigma am talking about it. That has been one crucial thing. Secondly, its terribly important than these organisations incorporate some training in self care and incorporate trauma and awareness into Data Management schemes. Find ways to pace generates occupational exposure. Simply have an open conversation about our evolving understanding of trauma. This is not just about the mental well being of a single generalists that is certainly important. Its really about the robust ability of generalists to bring the public, the information they need. A generous to is sidelined by ptsd is a and thats a loss to the world. So good to have you on the programme, thank you very much. Stay with us on bbc world news, still to come Serena Williams, chasing a record equalling 24th grand slam singles title, is knocked out of the Australian Open.

The latest headlines day four of Donald Trumps impeachment trial has begun as democrat prosecutors wrap up their case against the president. As china celebrates the Lunar New Year a Massive Campaign is underway to try to stop the spread of the new virus thats killed 26. Now, who would like to pay more taxes . Well a group of more than 130 of the worlds richest people say they do, and theyve written an open letter urging their fellow million and billionaire peers to do the same in the interest of fighting climate change. The letter, written by the group called the patriotic millionaires, argues taxes are the best tool to overcome innequality and to ensure the things our societies need get the funding they require. In their letter the group writes . Most reasonable so how realistic is this vision . Chuck collins is one of the co authors and signatories of the letter, i put that question to him a little earlier. I think ithink our i think our hope is that the more and more people recognise, my wealthy people recognise that both the Climate Crisis and the destabilising inequalities in our communities and societies are bad for everybody, including the health and well being of wealthy families and well being of wealthy families and so its actually in our self interest. We are kind of reaching out to say its time to step up, charity is important and its not a substitute for paying your taxes. And we are worried that our society has becoming more polarised we are going to sort of not have the nimbleness and support in society to address the ecological and Climate Crisis and so its really in all of our interest. Its all well and that thing lets pay my taxes but its up to that government in charge to use that money in a good and proper way to fight social inequality and to fight climate change. How do you know if that happens governments will play ball so to speak . There are things you need to do to strengthen democracies, over 2000 billionaires on the planet have disproportionate power to shape what government priorities are, wealthy people have disproportionate power is so not only should we do taxes but we should speak out in support of policies that reduce the destabilising inequalities and im sitting in boston in the united states, we need to tax ourselves and restore the progressive tax code that we used to have and make investments that lift up everybody and that really will be a healthier society and more nimble in our ability to respond to the ecological crisis ahead.

Huge swarms of locusts, like something out of the old testament, have been sweeping through large parts of east africa, destroying crops, and threatening the Food Security of the region. One of the worst affected countries is kenya, which last dealt with a plague of locusts on this scale our senior africa correspondent anne soy reports. From a distance, it looks Like Northern kenya is burning, but these are swarms of desert locusts, spreading like wildfire across the horn of africa. Just one swarm can have more than 200 million insects. These are tiny creatures flying above me. They look harmless, but if you consider that hundreds of millions of them are flying at the same time, the amount of destruction they can cause is unimaginable. Ali bila waqo tells me this is the second invasion of locusts hes witnessed in about 60 years. This time, hes lost nearly all his maize and bean crops. Translation its painful. We had no rain for several years. When it did finally rain last year, we were so happy, but then these insects have come and destroyed our crop. Weve incurred huge losses.
