welcome to bbc news, i'm simon pusey. our top stories: prosecutor turns defender, president trump adds ken starr, the man who sought bill clinton's impeachment, to his team. but you've got a good one now. even though they are trying to impeach the son of a (bleep). can you believe it? chants of death to america, as iran's supreme leader defends the military over the accidental shooting down of a ukrainian airlines plane. the us says it will screen passengers from china for symptoms of a new virus that has killed two people and infected many more, four teachers in los angeles sue delta airlines after a plane dumped fuel on their school during an emergency landing.

president trump's impeachment trial will properly get underway on tuesday, and on friday the white house unveiled an all star roster for its legal team. the defence will include the prosecutor from bill clinton's impeachment, ken starr, as well as celebrity lawyer alan dershowitz, who's previous high profile clients include oj simpson and jeffrey epstein. our north america correspondent aleem maqbool looks at the key hirings ahead of next week's trial. it is what we have come to expect from donald trump. newly revealed members of his legal team are made—for—television heavyweights. in ken starr, he also has a man considered a hero to the right. as independent counsel in the 19905 it was his investigation and the finding that bill clinton lied under oath about a relationship with an intern that led

to the then president's impeachment. happy new year to you. away we go now... recently he has been a contributor to mr trump's news network of choice, speaking out against the current impeachment. in alan dershowitz he has one of the most high—profile lawyers in the country, one who represented mike tyson, oj simpson and jeffrey epstein. he has also been vocally opposed to the impeachment of president trump. both are likely to bring showmanship to the historic events of the coming weeks. our correspondent, peter bowes, joins us from los angeles. peter, a big week coming up next week, what can we expect to see? we can expect fireworks. it will start slowly, i think with the presentations with both sides, the prosecution and the defence. we have

just heard about the president's start tea m just heard about the president's start team of lawyers that he has appointed to defend him, clearly a lot of public recognition in those names stopping the fireworks i'd refer to may come a little bit later in the trailand refer to may come a little bit later in the trail and it may well depend on that decision that we haven't heard, whether or not there will be witnesses, clearly the democrats who are bringing this prosecution from the majority house of representatives, they want to see witnesses. they believe there are individuals who can come to the senate and explain what they know about what went on during that time that president trump was talking to ukraine. can you give a sense of the scale of this story an american. we are hearing a lot of it in the uk and around the world but is this a massive story in the us? this is a huge story in the us. only the third time that a president has faced an impeachment trial. we have heard a lot of the senators in the past 2a hours talking about the serious

nature of what is facing them, the decision that they have to make, because the ultimate decision is going to be should this president keep hisjob? going to be should this president keep his job? and going to be should this president keep hisjob? and if he is found guilty he will be thrown out of office straightaway and the vice president mike pence will be installed as the president. that is a very big deal. if it comes to that, and it is extremely unlikely. who are we likely to see next week? we have heard a lot from lev parnas recently, who are the key players we will see next week? lev parnas is this ukrainian — american businessman who has given a couple of high—profile american interviews. he was involved with rudy giuliani, the president's personal lawyer, in attempting, it seems, to put pressure on ukraine to announce that there was an investigation intojoe biden. he is a potential witness. at the moment we don't know if he will

be called as a witness, we may not see him as a part of this trail at all so initially or we will get to see are the prosecutors, adam schiff who is the chief of the cuter on the side of the democrats, and the president's defence. side of the democrats, and the president's defencelj side of the democrats, and the president's defence. i have a feeling we're going to be talking to you about this again, but for now thatis you about this again, but for now that is all we have time for. thank you very much indeed. the canadian prime minister, justin trudeau, has insisted that iran must pay compensation for the shooting down of the ukrainian airliner last week. 176 people were killed, 57 of those who died were canadian citizens. as a first step, the government will give families of the victims who are canadian citizens or permanent residents $25,000 per victim to assist with their immediate needs

such as funeral arrangements and travel. this is a unique and unprecedented situation because of the international sanctions placed on iran and the difficulties that that imposes on these families. i want to be clear. we expect iran to compensate these families. i have met them. they cannot wait weeks, they need support now. that was justin trudeau speaking that wasjustin trudeau speaking a little earlier. meanwhile, president trump has warned iran's supreme leader ayatollah khamenei to be "very careful with his words", after he attacked the united states in a public sermon in tehran. in his friday address to thousands of worshippers, ayatollah khamenei branded president trump a clown, and praised recent missile strikes against american bases in iraq. here's our middle east correspondent, quentin sommerville. chanting.

it's eight years since ayatollah ali khamenei led friday prayers. his central message hasn't changed much. translation: the evil us government keeps repeating that we stand beside iranian people. you are lying — even if you are standing beside iranian people, it is just so you can stab them with your poison daggers. "death to america, death to england", chanted the crowd. thousands were bussed in from local mosques and given banners to wave. the ayatollah‘s appearance, and these loyalists, are meant to project strength, at a time of weakness for iran. looking down from above, qasem soleimani — the country's ruthless regional fixer. his assassination by the united states has wounded iran. the accidental shooting down

of the ukrainian passenger plane with iranians on board brought more trouble. angry crowds defaced the dead general‘s posters. in neighbouring iraq, iran and america continue their battle for influence. when iran and america fight, often it's iraq who bleeds. here in baghdad and across the country, there is a revolt against the government and against iranian influence. tehran has spent decades building up enormous power here. that power is now facing unprecedented pressure. they have been on these streets since october and caused the prime minister to resign and parliament to agree a new electoral law. but that's not enough. for many, iran and america are no longer welcome here. translation: i send a message to us and iran. we wish iraqis will not be either eastern or western. we want iraq to be ruled by iraqis.

change was already coming here in iraq, but the killing of qasem soleimani on iraqi soil means it may come sooner. with enough trouble of their own, iraqis are fast losing patience with america and iran. quentin sommerville, bbc news, baghdad. the united states is beginning screening passengers arriving at three airports from the chinese city of wuhan. they're looking for symptoms of a new respiratory virus that has killed two people and infected dozens more. the checks will take place at los angeles, san francisco and jfk airport in new york. the new virus was detected in wuhan last month; cases have since been reported injapan and thailand. dr peter daszak is from the center for infection and immunity at the ecohealth alliance and an expert on global emerging diseases such as sars. he joins us from new york.

peter, this seems to have become a lot more concerning in the past few days. we are beginning to know how likely it is for this virus to spread. we have had the first deaths and now the virus has appeared in two countries, multiple, two people infected in thailand, so it looks like it has the capacity to spread through infected people. that doesn't sound great stopping just how bad can this outbreak be? any outbreak is a very intensely watched event, because it is unclear at the beginning ofan event, because it is unclear at the beginning of an outbreak, how likely it is foran beginning of an outbreak, how likely it is for an outbreak to spread and become a pandemic. we are rapidly identifying this as a new disease, finding out what the virus is that is causing it, and being open about the information. we are seeing too many infected people for it to be just a single event from animals to

people. it looks like there has been either more than one place where the people are picking up this virus or there is human to human spread which isa there is human to human spread which is a big concern. just what kind of challenges does it present to health officials being a new disease?m looks like the virus is closely related to sars. since sars emerged people have been developing vaccines but this virus is different. we don't know yet if those drugs and those vaccines work, so the risk is that it those vaccines work, so the risk is thatitis those vaccines work, so the risk is that it is something that begins to spread, that it is lethal and we don't have the capacity to control it. we know yet where this came from? no, all of the early indications are that it originated ina indications are that it originated in a wildlife market, a market that sells mainly seafood but also some mammals, mainly domestic mammals.

pork and a few birds, paltry. but it is really unclear whether that is the source of the outbreak. it may be that wildlife, we find that when we look at the genetic sequence of this virus, it looks very similar to viruses that we found in bats in china, and that is where the original source of the sars outbreak was too. so maybe the bats have gotten was too. so maybe the bats have gotte n into was too. so maybe the bats have gotten into a farm and infected some animals or people have been trading and eating bats and that is the origin nobody knows yet. until we find that out, we can't be sure that this won't happen again. i'm sure eve ryo ne this won't happen again. i'm sure everyone will be keeping a close ion story, thank you very much indeed. stay with us on bbc news, still to come: a special report on record amounts of cocaine being produced in colombia and how producers conspire to get it to a city near you. donald trump is now the 45th

president of the united states. he was sworn in before several hundred thousand people on the steps of capitol hill in washington. it's going to be only america first. america first. demonstrators waiting for mike gatting and his rebel cricket team were attacked with tear gas and set up on by police dogs. anti—apartheid campaigners say they will carry on the protests throughout the tour. they called him the butcher of lyon. klaus barbie is being held on a fraud charge in bolivia. west germany wants to extradite him for crimes committed in wartime france. millions came to bathe as close as possible to the spot. a tide of humanity, it is believed by officials to have broken all records.

this is bbc news, our main headline: president trump has revealed the team that will defend him in his senate impeachment trial. well let's stay with that story now. and we can speak live now to troy slaten who is a criminal defence trial lawyer and is in los angeles. within law circles, these are big names, aren't they, for donald trump. is this a victory already before the war has started, has he won a little battle in getting these quys won a little battle in getting these guys to defend him? it certainly is, this is a bit of a dream team. in full disclosure, judge ken starr was a professor of mine and later dean of my law school. so both alan dershowitz and ken starr are stars in the legal community and they have been very put down prolific on

television in the last several months defending the president's position and speaking out against the impeachment proceedings. are you saying from that that this is a trail about public perception as much as anyone else? we have got an election coming up soon. it certainly is. this is a political process and all of the jurors in this case are united states senators stopping those 100 jurors will have to justify their decision to their constituents in their home state and justify whatever decision they make, which is whether or not to remove the president from office. so all of these people are going to have to go back and see what their constituents think about what they did and certainly while these proceedings are going on, it is going to be televised gavel to gavel and the american people are used to seeing these names. alan dershowitz and judge ken starr. you talk about ken starr, he is famous for investigating clinton those years

ago. what do you remember of him because he obviously studied with him? i remember him as being very affable, very nice. it was a bit different than what i've remembered of him during the clinton impeachment proceedings, but there is nobody more qualified than professor alan dershowitz, who famously helped get o.j. simpson off on what seemed like an airtight murder case, so bothjudge ken starr and alan dershowitz, you really can't get much better than that. and how will the senate trail differ to the house of representatives trail, because there are obviously technicalities 20 them that are quite important? during the health proceedings, that was really like a grand jury. it was to draw up the articles of impeachment which are akin to an indictment, and they heard from any witnesses. we may not heard from any witnesses. we may not hear from heard from any witnesses. we may not hearfrom any heard from any witnesses. we may not hear from any witnesses in the senate. it will be up to the senators by majority rule to decide

whether or not they want to hear witnesses, whether they want to see any additional evidence stopping the chiefjustice of the united states supreme court will act as the presiding officer but it will also be very different because unlike the house, where each one of the members of the committee got to stand up on their soap box and grandstand and give a five—minute speech to begin with, or senators have to remain silent, which is very difficult for a politician and if they want to ask a politician and if they want to ask a question, then they have to submit it in writing to the chiefjustice who they will ask the question of either the house managers or the president's defence team. it is a huge story and something about it tells me that we're going to be speaking it a little more. for now, thank you so much indeed. four teachers in los angeles are suing the us carrier, delta air lines, for negligence after a pilot dumped fuel over their primary school playground earlier this week. the teachers say the fuel burned their skin, eyes and throats and sent children screaming for cover. gareth barlow reports:

this is the moment thousands of litres of aviation fuel rained down on los angeles. the delta air lines flight 89 dumps the fuel on tuesday before making an emergency landing shortly after takeoff. dozens of children and teachers outside in playgrounds as the plane flew overhead required medical treatment for skin irritation and breathing difficulties. i began feeling a light drizzle on my hair, my face, my body. i thought it was rain. and then i caught the scent of fuel. i started yelling for my students to come back inside the building. in a statement released on wednesday, the airline said:

i was scared. i was scared too. we were all scared. despite the airline saying that normal procedure was followed, the teacher's lawsuit alleges that delta air lines didn't inform traffic control of the need to jettison the fuel. had delta's pilot notified our personnel of the need to dump fuel, the flight would have been directed by air traffic control to a location and to an altitude from which fuel could have been released without danger to the teachers, the students and others at the school. more teachers, students and families may joint the lawsuit amid concerns about the long—term health impacts from the exposed toxins. gareth barlow, bbc news. let's get some of the day's other news. security forces in the chilean capital santiago have used tear

gas against protesters. there have been months of demonstrations against the government of president sebastian pinera, with people demanding social reforms and changes to the constitution. dozens have died since the movement began in october. us congresswoman ayanna pressley has revealed she is completely bald because of the hair—loss condition alopecia. the massachusetts democrat told the root website that she started noticing her hair was falling out last autumn. she eventually went totally bald in december. later in the video which she shared on social media, she took off her wig, revealing her baldness. apple may be forced to abandon its lightning connector cable, as eu legislators push for tech companies to operate one universal charging system. apple argues the proposed regulation would stifle innovation and be disruptive to consumers. european regulators will vote on the cable on a yet to be determined day. the french fashion designer jean paul gaultier says his next show in paris will be his last. he presented his first individual

collection more than a0 years ago, and has long been known for pushing boundaries and blurring the lines between men's and women's clothing. he says though that his work will go on. the colombian government says it's to restart aerial spraying of coca leaves with herbicide, in an effort to reduce the record levels of cocaine currently produced in the country. spraying was suspended in 2015 after a study found the chemical used could cause cancer. since then, the area under coca cultivation has tripled, with much of the cocaine produced ending up in the us. our social affairs correspondent michael buchanan travelled to colombia to find out what else is behind the surge in production. in the middle of the andes, after a three—hour hike, i meet the foot soldiers of the cocaine trade. the farmers. how old are you?

every two months, they harvest a crop of coca leaves. it pays them around £75 a month each, mainly for what they do with the leaves. they add a variety of toxins, including ammonia and petrol. the process creates this valuable paste, which the narcos are willing to kill for. colombia's indigenous groups are under attack, murdered for trying to rid their communities of criminal gangs. canas valasco was one of over 50 members of the nasa people killed last year, assassinated in front of his wife messa.

colombia is producing more cocaine than ever before. a peace deal in 2016 ended the longest running civil war, but the agreement has allowed narco traffickers to expand their production and control of the cocaine trade. one smuggler told me how easy it is to export the drug. the smuggler often hides the drug among the vast consignments of bananas that head overseas. he says he sends at least six tonnes of cocaine to europe annually. how many of those shipments would you expect to reach europe?

the producers and consumers of cocaine both rely on each other, but rarely meet. so, i arrange for the coca farmers to speak to lewis, who we met last night, who occasionally takes the drug. so you never take cocaine yourselves? you feel a buzz, a rush, uplifted, you have plenty of energy, yeah, afterwards you feel terrible. thanks, guys. the farmer's advice turned lewis off cocaine, but many more are turning to the drug, creating problems in both colombia and the uk.

raymond buchanan, bbc news, colombia. and you can see more on this story in our world, colombia: the new cocaine war, on bbc world news and the bbc news channel this weekend at the following times on your screen. authorities in italy have discovered a painting by austrian artist gustav klimpt stolen 23 years ago, believed to be worth some $60 million. the painting ‘portrait of a lady‘ was taken from a gallery in the city of piachenza, with investigators believing the art work to have been stolen through a skylight. but in december a worker discovered a hidden compartment on the gallery's outer wall with the painting stashed inside, and the piece has now been confirmed as authentic. you can reach me on twitter, i'm @sipusey. but for now from me and the rest of the team, thanks a lot for watching

and do stay tuned right here on bbc news. hello. so much of the past week and indeed so much of the year thus far seems to have been dominated by cloud and wind and rain. at least there was something of a change on friday. it was a bright but really quite showery day for some, and of course at slightly higher levels in scotland it has led to a covering of snow. but at last, just in time for the weekend, we can talk about drier and sunny weather. it is the other face of winter. they will be some night—time frost and some ice around. and here's the set up. low pressure still close by to the north of the british isles over the past few hours,

and it doesn't look very promising when we look out into the atlantic. low pressure driving away towards the bay of biscay, and just in time for the weekend to settle things nicely, a big area of high pressure and it keeps on doing it. for the most part, that goes on into the middle of the forthcoming week as well. that is a real transformation, but the weekend will start much colder, with a hint of frost about it, something that many of you will not have seen for a while. at least it means it's going to be drier and sunnier as well. yes, there are still showers to be had in this north—westerly wind, most noticeable across the north—eastern quarter of scotland and through the northern isles. no more of12,13,14, which it has been in places over the past few days. temperatures resolutely in single figures. clear skies persisting under the influence of that area of high pressure. there will be a widespread frost away from the coast as we start sunday. some places will get “11 or —5, something in that order. here we go again. lots of dry, fine, sunny, crisp winter weather. the exception, perhaps this south—westerly, and more cloud just keeping the north—western quarter of scotland that wee bit milder.

there, the sunshine tempered by the amount of cloud. elsewhere it could be wall—to—wall sunshine. from sunday into monday, a cold and frosty start for the southern half of the british isles. milder in places across the north. watch out, it could be more extensive, fog patches for the commute on monday, but essentially, it's much the same sort of affair. the exception — thicker cloud may be producing the odd spot of rain through the northern and western isles. and as i take you on into the forthcoming week, under the influence of that high pressure, perhaps a subtle change in wind directions mayjust mean that many more of us get that mild hour, but it will stay dry for most.

this is bbc news, the headlines: the white house has confirmed who will be in the legal team which will defend president trump in his impeachment trial. it will include ken starr, the main prosecutor from bill clinton's impeachment — as well as the lawyer alan dershowitz, whose clients included oj simpson and jeffrey epstein. iran's supreme leader ayatollah ali khamenei has defended the country's armed forces after it admitted shooting down a passenger plane by mistake. canada's prime ministerjustin trudeau says iran must pay compensation to the 176 people who were killed — 57 of those were canadian citizens. the us says it will start to screen passengers from china for symptoms of a new coronavirus that has killed two people. there are 41 laboratory confirmed cases — but experts in london estimate the true number is closer to 1700. now on bbc news, it's

time for a look back
