Have been giving evidence about alleged russian Cyber Hacking before a powerful congressional committee. Russias always denied the accusations that relate to last years us president ial election. Nick bryant sent this report. Washington is investigating what could be the biggest political break in since watergate. In the 70s, it was the building belonging to the Democratic National committee that was burgled. In 2016, it was the Computer System at the partys present headquarters. A robbery in cyberspace, rather than in person. And Us Intelligence believes it was orchestrated by vladimir putin, from the kremlin, to help donald trump win the election. I want to welcome all our members back to the committee. Today, those allegations were aired publicly on capitol hill at this republican controlled congressional committee. Every american should be alarmed by russias attacks on our nation. There is no National Security interest more vital to the United States of america than the ability to hold free and Fair Elections without foreign interference. Thats why Congress Must set partisanship aside, follow the facts, and Work Together to devise comprehensive solutions to deter and defend against and, when necessary, respond to foreign Cyber Attacks. Americas director of National Intelligence, James Clapper, said he stood more resolutely by a Statement Released in october, before the election, that moscow was interfering to help donald trump. He was asked if that was an act of war. Whether or not that constitutes an act of war, i think, is a very heavy policy call that i dont believe the Intelligence Community should make, but it would certainly carry, in my view, great gravity. The President Elect has repeatedly rubbished the notion that he achieved a kremlin assisted victory, and has publicly poured scorn on americas spies. Hes also spoken approvingly ofjulian assange, the founder of wikileaks, who released the hacked e mails and claimed the russians werent involved. Thats enraged senators from both parties. Who actually is the benefactor of someone whos about to become Commander In Chief trashing the Intelligence Community . I think theres a difference between scepticism and disparagement. Director clapper, how would you describe mr assange . I dont think those of us in the Intelligence Community have a whole lot of respect for him. Then, this blunt and direct message for President Elect trump from a Senior Member of his own party. I want to let the President Elect know that its ok to challenge the intel, youre absolutely right to want to do so, but what i dont want you to do is undermine those who are serving our nation in this arena until youre absolutely sure they need to be undermined. And i think they need to be uplifted, not undermined. Trump tower these days has its own Micro Climate of twitter storms, and today was no different. The President Elect took to social media to complain thatjournalists were being dishonest in saying he agreed withjulian assange, and that he was a big fan of the Intelligence Community. The President Elect will receive a briefing from James Clapper at trump tower tomorrow and that has the potential to be a very frosty meeting. The key question, will it alter his present thinking, that the russian hacking claims are a cia cock up rather than part of a kremlin conspiracy . As we heard in nicks report, there were hints of the coming relationship between President Elect donald trump and Senior Intelligence officials. And it looks like it could be frosty. Our correspondent in washington, laura bicker, says tensions are already apparent. It did seem to come across that way. They were careful to toe the diplomatic line for as long as they could, but then came the kind of little killer blows, asked and prompted by questions, even by republicans, where they talked about scepticism, and Donald Trumps scepticism. ButJames Clapper, the director of National Intelligence in the us, said scepticism can be healthy but there is scepticism, and then there is disparagement. There was even a little push by the republican, lindsay graham, who came across saying, the President Elect may have his scepticism, but you are the guys who keep us safe, and again, the response came back that confidence in intelligence is crucial to the services, because they say without it, they cant do theirjobs. Its worth remembering, these top officials, who gave their evidence today, a very sobering assessment of a russia which they say was not just behind the hacking in the 2016 election, but a russia whose cyber activity is growing and needs combating. They gave that message, that sober assessment, and they are the eyes and ears of the us. The team will of course keep us up to date as and when the briefing for the President Elect takes place, so for the President Elect takes place, so do stay with bbc news for that.

The Chinese Government says it will create more than 13 million jobs over the next five years, through a multi billion dollar investment in Renewable Energy. For much of the past month, a huge swathe of northern china has been under a thick blanket of smog, a problem that has now prompted a switch to cleaner fuels as a political priority. This week, the authorities have renewed alerts for Air Pollution and fog across many parts of the country, including beijing. Thats where we can speak to our correspondent Stephen Mcdonnell now. Behind you we do see that thick blanket of smog continuing. We know this news comes just a few years after we heard president xijinping declare war on pollution. How bad has it been . Well, yes, as you can see from the bureau the air apocalypse, as it is referred to, continues in northern china. It has been terrible. Pm2. 5 are the general figures people use, the small particular the vatican get inside your body. Thats been hovering at about 300, 400 or 500. Small particles. They were hoping wind would clear it, but this is a short term solution. The interesting thing is that the government has declared a war on pollution and they have been putting really strict guidelines on what you can do, trying to limit factory production, a crackdown on coal fired power stations, and yet the pollution continues. The interesting thing is some research has come out from greenpeace this week, trying to analyse why this could be. A p pa re ntly analyse why this could be. Apparently partly because the prices of steel and cement have gone up. Production has also gone up. Ironically, this could also be because certain, well, more rundown factories are closing down, prices go factories are closing down, prices 9 up factories are closing down, prices go up so they are up in production. The other thing thats really interesting in china is the government cant control everything here. There are these illegal steel and cement production is going on, so and cement production is going on, so while Certain Companies do certain things they cant control everything thats happening across the vast northern part of the country. Weve got Chinese Lunar new year coming country. Weve got Chinese Lunar new yearcoming up, so country. Weve got Chinese Lunar new year coming up, so that might offer some reprieve at the end of the month, thats when factories usually stop. But in terms of the long term solution, this investment in renewables, how decent is it . Solution, this investment in renewables, how decent is mm solution, this investment in renewables, how decent is it . It is absolutely massive. The funny thing with china, its going to be on the one hand the biggest contributor to Greenhouse Gas emissions and also at the same time the biggest contributor on the planet to the solution. I mean, it is building this huge windfarms, solar on and on solar panels on an unseen scale. So it is putting the lives of dollars into Renewable Energy and policymakers are hoping it can catch up policymakers are hoping it can catch up in time to try to reduce some of these. All right, thank you. Last month, china lodged a complaint with the us after President Elect donald trump spoke to taiwans leader in a phone call. China sees taiwan as a breakaway province. And although us policy set in 1979 cut off formal relations with taiwan, the us is still taiwans most important ally. Well, in the 19905 taiwan had 30 diplomatic allies, but now it only has 21. Celia hatton looks at taiwans changing foreign relations, as the islands president makes a stopover in the us. Its a decades long political struggle the simmering tensions between taiwan and mainland china. The island of taiwan has been ruled separately since 1950. Many there want to push for formal independence from china. But the communist leaders in beijing view taiwan as a breakaway province, which must be reunited with the mainland one day. They insist other countries have to choose they cant have official relations with both beijing and taipei. The result taiwan has formal diplomatic ties with just a few countries, and that number is shrinking. In the 1990s, they had 30 diplomatic allies. Now that has dwindled to just 21. In contrast, china has more than 170. Just last month, the tiny african nation of Sao Tome And Principe resumed diplomatic relations with beijing, days after cutting ties with taiwan. It does not end there. Beijing is also reported to be courting the vatican state, as well as several of taiwans supporters in latin america. That may explain the taiwanese president s upcoming tour of honduras, nicaragua, el salvador and guatemala. But its tsai ing wens planned stopovers in the us that are raising eyebrows in beijing. Donald trump spoke directly with tsai ing wen over the phone, breaking with decades of us protocol. Tsai ing wen is not the first taiwanese president to make stopovers in the us. Stopovers are one of the few ways a taiwanese leader can sneak in meetings with us officials. Donald trump has not ruled out a face to face meeting with tsai ing wen after he takes over at the white house. So china will be keenly watching every minute of the taiwanese leaders time in the United States to see what that will mean for the delicate balance of relations between all three players.

But for the outgoing president s half sister, the end of his administration is as much about family as it policy. Maya soetoro ng grew up with mr Obama In Hawaii and tells us about their younger days, and what hell do when he leaves the oval office. Growing up, mum certainly gave us a wide range of tools to become the people who we are. That being said, my brother was kind of a regular guy who loved his friends, Who Bodysurfed and who played basketball. I think that hawaii has given my brother a sort of laid back attitude and an ease within himself. He wasnt a candidate for School President or anything like that, he didnt have, at least vocalised, aspirations for that level of civic engagement, and it wasnt until later that he became a little more serious, he became aware, after moving to la and then new york, i think of the challenges that we face as a country, as a people and community, and sought to find remedies and think about his place in his community and the country and the world. Election night was surreal. I will never forget who this victory truly belongs to. It belongs to you. That night i could see all the faces looking at him and they were inspired, excited. It was quite awesome to just recognise and understand how palpable their hopes and aspirations for his presidency were. I do think that he has changed. He has gotten wiser, he has become, i think, just a deeper version of himself. He obviously knows challenges with Greater Nuance and depth. He has seen a lot of suffering and sorrow, whether it was through International Disaster or the result of shootings in our country, and those were for him the most terrible days. So, our hearts are broken today for the parents and grandparents, sisters and brothers of these little children, and for the families of the adults who were lost. He often has said sandy hook was for him the worst day of his presidency. But i would say that he hasnt changed in any fundamental way. In terms of his relationships, who he is as a man, how he communicates, the things that he values, i think that he has remained remarkably unchanged, actually. That was Barack Obamas half sister sharing some historic images. Get ready for some pretty spectacular pictures.

It is goodbye from me in london. Thank you for watching. Hello there, good morning. Yesterday morning we saw the lowest temperature so far in england this winter, we got to 8. 1 in rural oxfordshire. This morning the frost is nowhere near as widespread. Therell be some across the south eastern quarter of the uk, but the further west you go, a lot more cloud, and that cloud is bringing at least some rain with it, but its also helping to keep the temperatures up, seven or eight degrees to start the day in glasgow and belfast. But itll be quite widespread in the western side of scotland, the eastern side faring a little bit better. Still cloudy and its quite wet in Northern Ireland first thing this morning. Some Rain Fringing into the western side of england and wales. Not quite into cornwall and devon at this stage, so its largely dry here. Head further east and its not just cold and frosty, therell be some patches of fog, and some of the fog will be slow to clear, and it could be quite dense in places, so do bear that in mind if youre heading out on the roads. Some fog in eastern anglia. Itll be a chilly old day here. Chilly here across northern england, but a fair bit of cloud and Just A Little Bit of rain first thing. Now, our main area of rain will topple its way further southwards and eastwards through the day, so itll eventually get down to the midlands. Some light and patchy rain here into the afternoon, but it never really gets to east anglia and the south east, here itll stay fairly cloudy into the afternoon, but therell some breaks, but its also where we see the lowest temperatures. Further west, mild air coming from the atlantic, could get into double figures. And that milder air, the less cold air, comes in from the atlantic on the westerly breeze, pushing a little bit of patchy rain across some parts first thing on saturday but, actually, into the weekend a lot less cold than what weve seen recently, but a lot of cloud across most places through the weekend and a little bit of patchy rain and drizzle, but certainly not a wash out, just pretty grey skies. So, we do see a lot of cloud on saturday, a little bit of rain here and there, maybe a few breaks in the cloud, top temperatures around about ten or 11 degrees. So something a lot less cold coming into the united kingdom, but weve got this cold northerly wind down across central and eastern parts of europe, and it really will be a very cold weekend through the balkans. It could go as low as 10, and thatll be daytime temperatures, so a big contrast across europe this weekend. Second part of the weekend, back on our shores, looks like the first part of the weekend, a lot of cloud, not much rain, but there will be some, and temperatures peaking at around about nine or 10 degrees. And then on into the early part of the coming week we start to see something a bit more unsettled developing, a Weather Front making its Way South And East across the uk, and note on our isobars on the chart, itll be quite windy, The Rain Starts in scotland and Northern Ireland and then a steady Progress Starts in england and Northern Ireland and then a steady Progress South and eastwards across the rest of the uk.
