is pulled from the rubble of a block of flats hit by an explosion. eight bodies have so far been found. and in half an hour we look at how the social media giants came under fire and the printed press got smaller — that's in review 2018: the media year. good afternoon. police have launched a terror investigation after an incident at manchester's victoria railway station last night in which three people, including a police officer, were stabbed. a 25—year—old man has been arrested on suspicion of attempted murder. the chief constable of greater manchester police described the incident as an "horrific attack". the victims‘ injuries have been described as serious

but not life—threatening. our correspondent danny savage reports from greater manchester police headquarters. a railway station in central manchester, just before 9pm last night. move away now. move! police restrain a man on the ground who moments earlier had been wielding a knife, attacking passers—by. a bbcjournalist was on the platform at the time and saw what happened. it's new year's eve, people have had a drink. they've probably — "it's just, it's just a fight." "it will fizzle out in the next few seconds." but then ijust heard the guy shout as part of a sentence, "allah", and i thought, that doesn't sound good. at the point i was just edging towards the tracks to jump onto the tracks he was pepper sprayed, he was tasered, theyjust kind of swarmed on him, brought him down. three people were stabbed,

one of them was a police officer, the other two were a man and woman in their 50s. the injuries are serious but not life—threatening. allahu akbar! a short time later the man was taken away from manchester victoria station by police, shouting "god is greatest" in arabic. this morning the chief constable of greater manchester police said it is being treated as a terrorist incident. we are treating this as a terrorist investigation. which is being led by counterterrorism officers with support from greater manchester police. they were working throughout the night to piece together the details of what happened and to identify the man who was arrested. manchester victoria station was closed overnight. it has now reopened, but this was obviously a very alarming and frightening incident for people there at the time. danny savage, bbc news, manchester. our correspondent danny savage updated us on the latest

with the investigation. what's happened this morning is that there has been a search of an address in cheetham hill in manchester. officers say they believe they have identified the man involved, they know who he is and his name and background to a certain extent. he's 25 years old and lives locally, and lives in manchester, but they won't give away any further public details about the identity of the attacker last night. but what is clear is that they are treating this as a terrorist attack. they say there is nothing to suggest that others are involved. they have good quality cctv of what happened and are, obviously, seeking witnesses as well. i think one other key factor is location of the attack, though. this was the manchester victoria station, which is adjacent to the manchester arena where the bomb attack, the suicide bomb attack happened back in 2017 at the end of that ariana grande concert in which 22 people were killed. and police believe that location is a factor with what happened last

night because many of those casualties were brought out from that concert through manchester victoria station at the time. so that is all part of the picture which they are building up, but what they are keen to stress is that this is very much a fast—moving, ongoing enquiry. a fast—moving, ongoing inquiry. they don't believe any other people are involved apart from the person they arrested last night but they are seeking to make sure that is the case as they carry out their investigations at the moment. danny savage reporting there. the mayor of greater manchester, andy burnham, has been giving his reaction to reporters at a news conference. last night's incident at victoria station was a vile attack i've spoken today to the security minister, minister ben wallace, who is obviously in touch with the home secretary. we will be working closely with the government over the coming hours and ensuring that there is full corporation from a greater manchester level with everything that's being done at a national level.

of course, as i said before, the ongoing investigation means that there is a limit to what can be said at this time, though, from what i do know, it has all the hallmarks and appears to be an isolated incident. while i would stress that people do need to remain vigilant, they should nevertheless not be unduly alarmed and should continue to go about their daily business. of course, the location of last night's attack will have been difficult for many people, given last yea r‘s difficult for many people, given last year's terror attack, and i'm sure there are many people who have been reminded of painful memories, andindeed been reminded of painful memories, and indeed of course we know there we re and indeed of course we know there were many people at the scene last night who were also very seriously affected by what they saw. it's why

we've commissioned through our resilience hub a helpline number which will be available in the coming hours to provide people with any support and reassurance that they may need. that was andy burnham there, the mayor of greater manchester. the american space agency, nasa, has confirmed its new horizons probe has made contact with earth after flying past the most distant object ever explored in our solar system. the encounter, which occurred some four billion miles away, was confirmed in a radio message. the probe acquired gigabytes of photos and other observations during the pass, which will now be sent home over the coming months. the team behind the probe held a press conference with some early findings from the venture. here's some of what they had to say. the image that i'm about to show you is the best image of ultima that we got before the flyby, and it's ok to

laugh, but it's better than the one we had yesterday. there it is. meet ultima! applause so, in my line of work, we like to interpret even images like this, and so interpret even images like this, and so what can we tell you from this image? well, first, we have a better handle on the size of ultima, it is about 35 by 15 kilometres, and you can see the scale bar in miles there. secondly you can see it irregular shape, and there are two possibilities here. one is that it has two globes, with the upper lobe being smaller than the lower lobe, so being smaller than the lower lobe, so they would be asymmetric, or it may be that these are two things that are actually in orbit around each other and just blurred together because of their proximity. tomorrow we will know which of those is the

case. what a difference a day makes. ultima thule is finally revealing its secrets to us, and even though its secrets to us, and even though it isa its secrets to us, and even though it is a pixelated blob still, it is a better pixilated blob! than the day before. and the fact that these images that we have just gotten and we are showing you today have allowed us to resolve something that was really puzzling to the scientists, because we knew, we were pretty certain that it was highly elongated, and it must be spinning, and in that kind of a situation you would expect to see brightness variations. here is an elongated object, this pain, and as you imagine the camera looking at this pen, in this dimension, in this direction, you see a lot of area, and when you flip it like that you see hardly anything. we expected to see hardly anything. we expected to see brightness variations of ultima thule overtime, and we weren't seeing that. that's because the poll is almost pointing towards the spacecraft, it is almost like a

propeller blade that is running around, and that explains everything, basically. we had the flyby actually occurred in the morning at about 7am, and then we had morning at about 7am, and then we ha d co nta ct morning at about 7am, and then we had contact with the spacecraft in the evening, about nine, so we pretty much spent the whole day here, and so this one, we celebrated at night, a little after midnight, and then we went home, and then came back early in the morning, and it was this feeling like, we already celebrated, but we really haven't got that signal back from the spacecraft, so, you know, it is a little bit different feeling. i think i was probably a little bit more nervous this time. but again, we did it again, so it's fantastic. applause so where exactly is the lump of ice and dust known as ultima thule? our science editor david shukman has this explanation. to explain what this

mission is all about, let's use our virtual studio and start at the middle of our solar system. orbiting closest to the sun are the four small rocky planets, including earth, and then further out there are four much larger planets. the best known of these is saturn, with its famous rings. and then right on the margin is tiny pluto, three billion miles away, but it turns out pluto is just one part of a massive outer zone we only started discovering in the last 20 years or so. thousands of tiny worlds and lumps of rock and ice, known as the kuiper belt. these are objects left over after the planets were formed. one of these is known as ultima thule and until now we've only had this artist's

impression of it. but after racing from earth on a 13—yearjourney, nasa's new horizons spacecraft, the most distant exploration in human history. that was david shukman. let's speak now to professor andrew coates from the mullard space science laboratory at university college london. hejoins me on the line now. good afternoon. you could hear the excitement from the team at nasa. just try to explain to us who don't follow these things closely what an achievement this is for us. you can really feel that they are really exploring at the edge of knowledge. it is unveiling a new world for the first time. so this particular region, the kuiper belt, is something we haven't been able to explore before, and there are hundreds of thousands of them, and they are comics waiting to happen, because every now and then, one is tipped into our solar system, we see spectacular comment and a number have happened in the past, most

recently the rosetta comet which was explored in detail by the european space agency's spacecraft rosetta. that was fantastic, that was a double lobe object which means it was two bits of material stuck together, and it looks like ultima thule may be the same sort of structure, so it is very exciting seeing this thing for the first time, and just seeing this thing for the first time, andjust in seeing this thing for the first time, and just in a matter of a day 01’ time, and just in a matter of a day or two, we should get better information about whether it is one object which is this bilobate kind of shape, or two separate object, we can't rule that out yet, but all will be revealed in the next few days. so i was going to ask you about the information that the spacecraft can send back. obviously images, we were talking about the high resolution ones that will come later. the fact that it is 4 billion miles away, it is so difficult to even copperhead, but it takes such a long time for the information to even get back to earth. even for the radio signals to come back, that is over six hours. so to compare that,

the light from our son that we see when the sun is up during the day ta kes when the sun is up during the day takes eight minutes to come from our sun. so here we are talking about over six hours, so this is really a distant exploration, and it is the most distant object that has ever been explored by a spacecraft. it is way beyond pluto on the classical planets including neptune, the outermost classical planet. but of course this spacecraft actually explored pluto as well, so this is unveiling kuiper belt objects for the first time, pluto was demoted from a status of planet famously a few years ago, and is now what we know of as a kuiper belt object, ice dwarf planet, so it changed its status. but the images from new horizons from that encounter showed a world where of things are going on, a heart—shaped on the surface,

there is nitrogen ice, lots of things, interesting geology going on, and totally unexpected things like red material which is associated with methane and nitrogen. working together in the same way that they do at titan, which we explored with the cassini mission. so it is a fantastic mission, and it will show over the next few days for some images to come down, adding a bit of colour information later this week, but then after that there is what is called a conjunction, so we won't hear from the spacecraft for a little while, for a couple of weeks, and then the science team will get back together in mid—january, and data trickles down really over the next couple of years. it is so far away that the information rate at which the information is coming back, it is one kilobit per second, so back, it is one kilobit per second, so that is much less than what we used to use as modems for connecting to e—mailfrom used to use as modems for connecting to e—mail from home. used to use as modems for connecting to e—mailfrom home. so it isjust amazing to be able to get

information back from all that distance. it is fascinating stuff. thank you very much for speaking to us thank you very much for speaking to us this afternoon, professor andrew coates. the headlines on bbc news: a terror investigation is launched after three people including a police officer are stabbed at manchester's victoria station. signals from the nasa space probe new horizons confirm it has successfully flown past icy mass ultima thule — the most distant object ever explored in the solar system. the archbishop of canterbury calls for an end to the "divisions of recent years" in his new year sermon. let's return now to brazil, and live pictures there ofjair let's return now to brazil, and live

pictures there of jair bolsonaro who has just been sworn in. pictures there of jair bolsonaro who hasjust been sworn in. he has been signing the book there, and his collea g u es signing the book there, and his colleagues are now doing so. we saw earlier thousands of people turning out on the streets to welcome the new president hu won the election backin new president hu won the election back in october by a wide margin. mr bolsonaro has been accused of being a controversialfigure, he has been accused of racist, homophobic remarks which have angered many people. but he won the election by promising to clamp down on corruption in brazil. you can see here that they are all signing the document at the inauguration which is taking place at the congress building in brasilia. sport and for a full round up, from the bbc sport centre, here's sarah. thank you very much. we start with

leicester city. leicester city won the first premier league match of the year, they beat everton1—0 at goodison park. jamie vardy was the match winner with a goal in the second half. leicester up to 7th in the table after a really good run of festive fixtures — they've taken nine points from a possible 12. two other premier league matches today, and arsenal have beaten fulham 4—1 at the emirates — decent response from the home side after that drubbing against liverpool. spurs can move back up to second with a win at cardiff although the home side picked up 4 points from their last 2 matches. kick off in 15 minutes' time. there was a cracking match in the championship as nottingham forest beat leaders leeds 4—2. the visitors had gone down to ten men in the first half, but they looked to be on for a remarkable turnaround when they went 2—1 in front. but forest struck a leveller through jack colback‘s second goal of the game, and then went in front when daryl murphy headed in from this corner. leeds eventually tired

and conceded a fourth late on, but they are still top of the league after promotion rivals norwich and west brom both dropped points. all today's results from across the divisions are on the bbc sport website. andy murray says he doesn't know how much longer he'll be able to play competitive tennis. last year was virtually a write—off following hip surgery, but he made a winning start to the year in brisbane today as andy swiss reports. he's back, but for how much longer? fewer a re he's back, but for how much longer? fewer are as keen to forget 2018 as andy murray. he spent most of it out injured, and his first match since september rate as many questions as a nswe i’s. september rate as many questions as answers. on the plus side, there we re answers. on the plus side, there were flashes of his familiar brilliance. he might have slipped to 240 in the world rankings, but he was far too good for his opponent,

james duckworth. but he admitted his long—standing hip problem is still causing discomfort, and after a straight sets win, a question about his recent injury battle left him close to tears. it's been a really ha rd close to tears. it's been a really hard 18 months, a lot of ups and downs, it was trickyjust hard 18 months, a lot of ups and downs, it was tricky just a hard 18 months, a lot of ups and downs, it was trickyjust a kind of get back on the court competing again, so i'm happy i'm back out here again. i want to try and enjoy it as much as i can, and just try and enjoy playing tennis as long as ican. i and enjoy playing tennis as long as i can. i don't know how much longer it's going to last, but we'll see. an emotional day, then, for one of british sport's biggest stars. he hopes this comeback will last, but a reminder perhaps to enjoy his talent while we can. andy swiss, bbc news. the british number1johanna konta's also in action in brisbane, she beat the former us open winner sloane stephens in straight sets. konta's had a difficult 12 months, but now has a new coach and says she's trying to create something new and better in 2019. two greats of the game faced

off in perth earlier as roger federer came out on top against serena williams in a mixed doubles match at the hopman cup. this was the first time they had played against each other in a tournament. federer and belinda bencic, representing switzerland, are the defending champions and they beat williams and her us teamate frances tiafoe in straight sets. federer says it was an ‘honour‘ to play against serena. geraint thomas and chris froome are both going to focus on the tour de france this year. froome isn't going to defend his giro d'italia title in may, conserving his energy for a tilt at a record—equalling fifth tour title in france injuly. that means he'll go head—to—head with fellow team sky rider thomas again, who won the tour for the first time last year, despite froome being team leader. that's all the sport for now. thank you very much, sarah.

an 11—month—old baby boy has been rescued from the rubble of an apartment block that collapsed on new year's eve in russia. at least eight people died when a suspected gas explosion on monday brought down part of the building. more than 30 people are still unaccounted for. simon jones has more. out of the rubble, a story of hope. a baby rescued after enduring a night of freezing temperatures. the child has been taken to hospital in a critical condition but doctors remain optimistic and the baby's mother also survived. it was a huge blast. there are fears that further parts of the building could collapse, hampering the search effort. several bodies have already been found, many are still missing. people are desperate for news of survivors. translation: we are so very sorry. we were crying all night long. we felt really bad. the russian president has visited some of those injured in hospital. translation: unfortunately such a tragedy took place in magnitogorsk. i would like to express my condolences to the families

of the victims and to assure those affected that we will do everything to help and support them. an emergency centre has been set up to help those who have lost everything. the explosion has been blamed on a gas leak. it's thought that it ripped through the first floor, then the seven stories above collapsed. the building was home to 120 people — 48 flats were destroyed. people want answers. why did the building come down so easily? a criminal investigation is under way. but this baby has at least provided optimism that others could still be found in the rubble. the archbishop of canterbury, justin welby, has called for an end to what he called the "divisions of recent yea rs." in his new year message, he says the uk is "wonderfully more diverse" than it used to be — yet people are disagreeing on many things and are struggling to disagree well. our religon editor martin bashir reports. can i make you a cup of coffee? for his new year's message,

the archbishop of canterbury, justin welby, didn't venture far. this is the kitchen at his london residence in lambeth palace. a home that he shares each year with around 20 young people who commit themselves to ten months of prayer, study and community service. they have an extraordinary range of backgrounds, cultures and opinions. they live together, cook together, volunteer with charities together, and, because they are human, they clash together. named after a benedictine monk who became archbishop of canterbury at the end of the 11th century, the community of st anselm is an attempt to challenge whatjustin welby says is increasing division and rancour in british society. we disagree on many things and we are struggling with how to disagree well. turn on the television, read the news, and you see a lot that could tempt you to despair.

quoting the gospel ofjohn, the archbishop said thatjesus chose community over conflict, hope over despair, and he says that we should do the same in 2019. hope lies in our capacity to approach this new year in a spirit of openness towards each other. that will involve choosing to see ourselves as neighbours, as fellow citizens, as communities, each with something to contribute. and he acknowledged how challenging this will be in the current political climate. with the struggles and divisions of recent years, that will not be easy. but that difficult work is part of the joy and blessing of being a community. whether it's the 20 people here or millions of us, i wish all of us a happy, and more importantly hope—filled, new year. eight people in france have been

rescued after spending their new year's eve trapped on a funfair ride, more than 50 metres in the air. the ride malfunctioned in the city of rennes in brittany. a warning — there is some flashing in these images. a helicopter was called in to help rescue the three adults and five teenagers from the 52—metre high ‘bombermaxxx‘ ride which had suffered a technical fault and stopped at around 8.30pm. the eight people, the youngestjust 13 years old, were left high in the air with their feet dangling in what was to become a nine—hour ordealfor some of them. initial attempts to reach those trapped using ladders failed, before a rescuer was winched down by the helicopter. they were evacuated one by one with the last person finally getting off the ride at around 6am. the ride's owner said a new part had broken. now it's time for a look

at the weather with chris fawkes. —— with louise lear. good evening. for those of us lucky enough to have some sunshine today, that will lead toa some sunshine today, that will lead to a cold and wintry night. there is a lwa ys to a cold and wintry night. there is always the risk of an isolated shower on the north sea coasts, and that will prevent the temperatures falling below freezing, but further west we will see temperatures below freezing, a frosty start but a sparkling one on wednesday, lots of sunshine which continues particularly further inland away from those coasts. a dry sunny day for many, always the risk of perhaps a little more cloud running down through the north sea coasts, maybe it the south west, and that is where temperatures will sit at six or 7 degrees, inland in the sunshine looking at a maximum of five, so on

the chilly side. thursday will be cold and frosty, but again there will be dry and sunny spells on offer, indications of something a little less cold as we head towards the weekend. good night. hello this is bbc news with vicki young. the headlines: a terror investigation is launched — after three people including a police officer are stabbed at manchester's victoria station. signals from the nasa space probe new horizons confirm it has successfully flown past icy mass ultima tooley — the most distant object every explored in the solar system. the archbishop of canterbury calls for an end to the "divisions of recent years" in his new year sermon. in russia, an eleven—month—old baby is pulled from the rubble of a block of flats hit by an explosion — eight bodies have so far been found. jair bolsonaro, a far—right politician vowing a crackdown on crime and corruption, is sworn in as brazil's new president in front of congress in brasilia.

now on bbc news — it's the year the social media giants came under fire, the printed press got smaller, and blockbuster tv got even bigger. the bbc‘s amol rajan gives his take on the last 12 months in review 2018: the media year. hello and welcome to the media year 2018. in the next half an hour, we are going to look at the intersection between technology and the media over the past 12 months, a golden age of tv and audio and the increasing impact of data on all our lives. this has been the year of the techlash, a global backlash
