this is bbc news. i'm simon pusey, with the latest headlines for viewers in the uk and around the world. millions of travellers face disruption over christmas, as the world—wide record surge in omicron cases means cancelled flights and staff shortages. worried about the variant, omicron, and all that, at the same time i'm just, let's get back to our lives a little bit. a christmas midnight mass at the church of the nativity in bethlehem — and a message from the pope calling for more solidarity with the poor. the queen is expected to give a very personal christmas message this year — her first since the death of her husband prince philip. final preparations are under way for the launch of a space telescope that could transform our understanding of the universe.

welcome to our viewers on pbs in america and around the globe. more than 2,000 flights have been cancelled across the world, as people try to complete last minute journeys to spend christmas with friends and families. some major airlines have blamed the cancellations on the pandemic. china and the us are the worst affected countries. azadeh moshiri reports. festivities may be going ahead this year but millions are still having difficulty reaching their families. with the omicron variant surging quickly around the world, it's causing chaos within airlines with crews testing positive or needing to isolate.

in the us, united airlines and delta air lines already cancelled hundreds of christmas eve flights and warned of more cancellations throughout the weekend. i spoke to one passenger who is now forced to travel on christmas day. your grandmother is based in bosnia and you haven't seen her in years but the family reunion has been halted. what happened 7 unfortunately we were in the airport and sitting there and waiting for our flight from orlando to charlotte and we got a notification that our flight from charlotte to munich had been cancelled. completely out of the blue, no idea of what was going on, no prior notice and we went ahead and, you know, we went to the ticket counter to ask and they said the best thing we could do still get on the flight to charlotte because our luggage was still being sent there on the aeroplane. the flight tracking firm flightaware has said more than 2,000 christmas eve flights have been cancelled globally.

explaining their decision, delta air lines warned. in the us, daily omicron cases have risen beyond the peak of the delta wave and hospitals are quickly filling up. despite this, many are still taking the risk to reach their loved ones. i'm very scared to be flying, to be honest. i'm glad to see everyone looks pretty masked up. ijust hope people on the plane as respectful of those around them. fully vaxxed and boosted and all of that and i said, you know, i'm just so glad to be back with people, doing what we do. it kind of feels good. i mean, i'm still worried about the variant, omicron, and all that, but at the same time, i'm just like you know what? let'sjust — let's get back to living our lives a little bit. airlines are now calling for reduced quarantine for vaccinated staff, with delta's ceo asking for those experiencing breakthrough infections to isolate five days instead of ten. but in the meantime,

many will still be struggling to make it home for the holidays. azadeh moshiri, bbc news. well, earlier i spoke to william schaffner, who's professor of health policy and infectious diseases at the vanderbilt university school of medicine. we began by discussing the us travel industry and the havoc caused by the spread of omicron. we are obviously entering new territory. this omicron variant can give mild illness that is not requiring hospitalisation in people who are vaccinated and commended, boosted. but the important thing is hospitalisation is not required. on the other hand, if it strikes someone who is unvaccinated, there is still the risk of hospitalisation and hospitalisations are creeping up hospitalisations are creeping up around the country at the present time. and, as a result, we have a great deal of

confusion in the travel industry and elsewhere. and, . iven industry and elsewhere. and, given that. — industry and elsewhere. and, given that, what _ industry and elsewhere. and, given that, what advice - industry and elsewhere. and, | given that, what advice would you give to people who are watching our who are thinking of travelling maybe for christmas to see loved ones, but they may be worried about catching the virus?— catching the virus? first of all, be sure _ catching the virus? first of all, be sure and _ catching the virus? first of all, be sure and contact i catching the virus? first of l all, be sure and contact your airline first. but then where your mouth when you are in public places to and have good hand hygiene, and if you have those rapid tests available before you gather together with your family and friends everyone get yourfamily and friends everyone get a rapid test and if they are all negative then you can share the joy. you can share the 'oy. share the 'o you can share the 'oy. share the joy indeed. _ you can share the joy. share the joy indeed. there - you can share the joy. share the joy indeed. there are i you can share the joy. share | the joy indeed. there are 500 million tests that are going to be sent out to american families are so they can test themselves, but that is not going to happen untiljanuary, is that too late? going to happen untiljanuary, is that too late?— is that too late? well, it's never too _ is that too late? well, it's never too late. _ is that too late? well, it's never too late. of - is that too late? well, it's never too late. of course | is that too late? well, it's i never too late. of course we would wish more more quickly, but we're going to be using along with vaccination and all of the other interventions to try to bring omicron to a low

level so we can open up society more safely in the future. testing will be part of that strategy and very helpful as businesses start to get together, entertainment venues are using it, you in europe are using testing more than we are at the present time. i think we can catch up and learn from your lessons.— can catch up and learn from your lessons. and in terms of vaccine take-up, _ your lessons. and in terms of vaccine take-up, what - your lessons. and in terms of vaccine take-up, what is - your lessons. and in terms of vaccine take-up, what is the | your lessons. and in terms of. vaccine take-up, what is the us vaccine take—up, what is the us looking like in general? is the message getting out there now that people need to be judged and boosted to spend time with loved ones over christmas? well, the message has been out there for a long time and, quite seriously, people are getting their boosters, but they are not bringing their children into be vaccinated, those five and older, and then we have a residual group of adults who have resisted vaccination until the present time and that's rather baked in, as we say. i don't know what can motivate them other

thanit what can motivate them other than it might be mandates, requirements for vaccination to do any number of things in our society. do any number of things in our socie . ~ ., ., , society. william schaffner speaking _ society. william schaffner speaking to _ society. william schaffner speaking to me _ society. william schaffner speaking to me a - society. william schaffner speaking to me a little . speaking to me a little earlier. let's get some of the day's other news. the number of daily covid infections recorded in the uk has reached another record high. 122,000 more cases have been confirmed. it follows an estimate from the office for national statistics that more than 1.7 million people had the disease last week. the un says three million people are in need of assistance in the philippines, among them around a million children. it comes after typhoon rai devastated the country's south—eastern islands. many have lost everything and are heading into christmas unsure if they'll be able to feed their families. christmas celebrations have taken place in bethlehem, including an annual procession led by the head of the roman catholic church in the region. the events culminated in a mass at the church of the nativity, built on the spot where it's believed thatjesus was born. our middle east correspondent

tom bateman reports. in manger square, they wait for the biggest night of the year. a christmas procession follows the route believed to have been taken by mary and joseph. it's a march of faith. but this season's greetings are mainly between the locals. the scout bands are a fixture of christmas in manger square and you can feel the energy. but what is missing are the international visitors and pilgrims that would usually be thronging the square here, and that is a devastating blow for the second year running because bethlehem needs tourism to keep surviving. the glimmers of tourism restarting last month have gone, derailed by border closures due to the new covid variant. people trying to find joy and happiness from nothing. so it's very interesting, very impressive. since the beginning of 2020,

everything is closed. all hotels are empty. it's very, very difficult - for people — especially those who are working i in tourism sector. they are selling somej of the land to houses. the characters of christmas come to life. in this olive wood factory, ibrahim is the only worker here today. normally, he'd be joined by four more. for palestinian christians in this part of the west bank, life has been a challenge, says nabeel, whose family has run the shop for decades. we could keep our workers till the moment, but i don't know. you know, it's hard. i have two shops — one is here. the one on the manger square, it's been like 2a months, zero income. it's sad — it's not normal to see bethlehem this way. but at christmas, there's always light to look up to. as this town celebrates, it remains a year of hope against the odds. merry christmas! tom bateman,

bbc news, bethlehem. pope francis has urged catholics to "look beyond all the lights and decorations" and remember the neediest. in his homily during the christmas eve mass the pope said the fact thatjesus was born in poverty should remind people, that serving others was more important than seeking status or spending a lifetime in pursuit of success. here's a little taste of the service. singing the queen will spend christmas day at windsor castle with a smaller group of family members than in previous years. she decided not to travel to sandringham for her traditional family gathering

as a precautionary measure amid rising coronavirus cases. she's expected to give a very personal christmas message later — her first since the death of her husband, prince philip. there are some flashing images in this report from our royal correspondent, nicholas witchell. rehearsing at windsor for their part in the queen's christmas broadcast, the central band of the royal british legion will play the national anthem which begins the broadcast. this year's christmas message — a still from which has been issued by buckingham palace — will be an unusually personal one. the queen is wearing a brooch which she wore on her honeymoon, and on the desk beside her, a photograph of her and prince philip taken in 2007, when they celebrated their diamond wedding anniversary. it's eight months now since philip's death. so far, the queen has not spoken publicly in any detail about how much he meant to her. her broadcast will be an opportunity for her to do so.

within the royal family, mindful that this will be the queen's first christmas without her husband, arrangements have been adjusted so that she won't be alone. the prince of wales and the duchess of cornwall will be with her at windsor, other members of the family, the wessexes and the gloucesters, will also be there. absent, of course, will be the duke and duchess of sussex. from their home in california, they've issued this photograph wishing their supporters happy holidays. it shows harry and meghan with their son, archie, and their daughter, lilibet, pictured for the first time. and so, at the end of a year touched by personal sadness, and some family tensions, thoughts will start to look ahead to next year and the celebrations to mark the queen's 70 years on the throne. uppermost in the minds of the palace planners, of course, will be the question of the queen's health. it's always a sensitive matter. it has particular significance

after the recent concerns, and given that next year is the year of her platinumjubilee. the queen will certainly want to be involved in thejubilee as fully as possible, and there will be another event of special significance to her — a service of thanksgiving for the life of the duke of edinburgh, which, it has been announced, will take place at westminster abbey in the spring. nicholas witchell, bbc news. stay with us on bbc news. still to come: 50 years after the classic christmas joni mitchell song, the video finally gets released. the world of music's been paying tribute to george michael, who's died from suspected heart failure at the age of 53. he sold well over 100 million albums in a career spanning more than three decades.

means cancelled flights and staff shortages. the final preparations are under way for the rescheduled launch of a space telescope that could transform our understanding of the universe. the rocket carrying the james webb space telescope will take off from french guiana later on saturday. it's the successor to the hubble space telescope and it will give us a much deeper understanding of our universe and how it came about. our science editor rebecca morelle reports. it's taken 30 years to develop, cost more than $10 billion and has involved thousands of scientists. now, the james webb space telescope is finally ready to launch, to begin the most ambitious astronomy mission ever attempted. this telescope is absolutely the biggest and most complex and most powerful telescope that we've ever attempted to send to space. all of us astronomers are extremely eager to get this telescope into space. but, you know, i think it's

going to work and i think it's going to, again, you know, just completely revolutionise how we understand the cosmos. the telescope is a successor to hubble, which has given us amazing images, butjames webb is much more powerful. its mirror is almost three times bigger, which means it can reveal parts of the cosmos we've never seen before. gazing up into the heavens can help us to answer some of the biggest questions, like where we come from and how did we get here? this space telescope will help us to look further back in time than ever before, to 13.5 billion years ago, revealing the light from the very first stars to shine. the final preparations have been under way. it's an incredibly tight fit as the rocket is tentatively lowered over the folded telescope. this is high—stakes science but, if it works, it could lead to discoveries that scientists haven't even dreamt of. rebecca morrell, bbc news. dr sarah kendrew is

an astronomer with the european space agency and is at the launch site in french guiana. she says the team involved is excited and a little apprehensive. yes, it has been a very interesting christmas. we're all very excited. a small team of us here from the european space agency in french guiana went for a very quiet, low—key christmas eve dinner. we're all trying to get an early night now because we're going to be up and early tomorrow to get ready —— we're going to be up bright and early tomorrow to get ready for the launch. if all goes according to plan, what will this telescope allow us to do in the future that others, including the hubble, haven't? yeah, so it's giving us, like, really crucial coverage in infrared light, which is something that the hubble space telescope was much more focused on visible light and the infrared coverage is really a key to letting us

probe back further into the history of the universe, so really giving us a view of those very first kind of generation of stars and galaxies that formed after the big bang, also other things like atmospheres around exoplanets — so these are planets around other stars in the galaxy. it's going to tell us about the chemistry and the conditions on those other planetary systems and really kind of help us understand how the building blocks of life may have formed. it's been 30 years in the making, it's cost billions of dollars — just why has it taken so long? it's an incredibly ambitious project. there's a lot of technical complexity. it's also a huge project — as we heard just before, there have been thousands of people who have worked on this project over the lifetime of the development. you know, it's taken a long time, it's been a long road, but, really, considering

the scale and the ambition of the project, i think that's not surprising and it's — with the number of technical challenges that we've had with the mission, it's been really important to address them carefully and to take our time, and do not rush things. dr sarah kendrew there. and now for a christmas treat, see if you can guess this famous holiday track. instrumental music plays. well the instrumental is, of course, jingle bells from joni mitchell's classic river. the song first appeared on her landmark album blue back in 1971 and, 50 years later, it's gotten its first music video in time for christmas. let's have a listen. # they're cutting down trees. # they're putting up reindeer and singing songs of joy and peace. # oh, i wish i had a river i could skate away on.

most of the video is in black and white, until the end, when the river turns blue. and while it may sound christmassy, there's another theme throughout, as you can guess from this message from joni which accompanied the video. i've been speaking to matvey rezanov, the animation artist who directed the music video, on the message and how he got it across. i think the choice of a black and white palette was really essential here and, as you rightfully pointed out, the colour symbolises hope and solace, because even in the deepest sadness, there is some kind of calmness. and ijust tried to do justice to the lyrics and that was my goal, basically, and to the song itself and what it means.

it's really effective. congratulations. why did you decide on the watercolour effect? is that a nod tojoni being a painter herself? it is definitely a nod tojoni being a painter but i think the decision was made by rhino records — i work with them, doran tyson and lisa glines. they approached me because that is what i do, i do watercolour animation. so, that the idea came from them, ijust... how much artistic license did you have yourself? did you have a complete blank canvas to do what you wanted? they did indicate the general idea and they wanted to be like symbols — symbolic. other than that, i had really a lot of creative freedom and i really appreciated it. 169,000 views on youtube in just a day — what has the reaction been like that you have been getting? it's really overwhelming. i think this song means a lot to different people and it

really speaks to different people's, you know, hearts and lives. a lot of people approached me and i'm really grateful that they say that the visuals correspond to the lyrics quite well, so that's a huge honourfor me. and you've got the black and white, obviously, that go through the video but then at the end, there is an element of hope, right, with the colour coming in? that's correct, yes. and what hasjoni said to you — or said to people about it herself? you know, she saw the storyboards and that was a really crucial moment because that's when i presented the overall flow and how it will look, and she approved it — which was a really, really big deal — and i was executing that video, i was actually really nervous because, as you said, she is an artist herself, a great artist, and she has an incredible artistic eye. so when i sent the video and it got approved in an hour, that meant the world to me.

and how long did the whole process take, because obviously it has been released just in time for christmas — perfect timing — but i guess you have been working on this for quite a long time? actually, it took me a0 days. outro of river plays. matvey rezanov there. for millions around the world the big day has arrived and for millions more, it is only hours away. christmas is being celebrated across the globe. a lot of food will be eaten and a lot of presents will be opened — assuming one man in particular heads in the right direction. tim allman explains. # you better watch out. # you better not cry. # better not pout — i'm telling you why.

# santa claus is coming to town. this has become almost as big a festive tradition as crackers, turkey, and tinsel. for more than 65 years, the north american aerospace defense command, or norad, has been tracking father christmas as he makes his way around the world. of course, this year, he has to deliver presents in a covid—secure environment. i'm sure santa is taking precautions. he — obviously, when he's riding the sleigh, he has to call out those commands to the reindeer, so he might have his mask off there so they can hear him, but i'm sure he's following the, you know, six feet away and wearing his mask when he's around others and his elves, et cetera. before he left, father christmas — or someone who looks like him — made a quick detour to thailand, exchanging his reindeerfor elephants — elephants with face masks. they were delivering presents to this school not far from bangkok.

the children seemed to enjoy it, although animal rights groups think this is one tradition that's had its day. if we want to teach children a christmas message, if we want to spread the christmas spirit, the best thing that we can do is to leave animals out of performances like this one and use people instead. back on hisjourney, and there is no chance the big man would miss this house. here in danvers, massachusetts, they light this building up to raise money for a local children's hospital. most spectacle, more bright lights this time in taiwan — a giant santa claus next to a giant christmas tree. this time of year is special, wherever you are. tim allman, bbc news. let's look at where he is, it looks like cleveland, ohio, and delivered over 5 billion presence. good lad. you can reach me on twitter.

i'm @sipusey. please stay tuned. —— presents. hello there. merry christmas to you. some of us will see some snow during this christmas period, mainly across the hills of the northern half of the uk. further south, it'll tend to be milder, so any precipitation will be rain. and we've got areas of low pressure pushing into the south west and they're weather fronts bringing outbreaks of rain. as these weather fronts slowly push north—eastwards into that stubborn area of colder air which is sitting to the north—east of the country, then this is where we're likely to see some of that rain turn to snow. so, we're starting christmas day morning off on a very cold, frosty note across scotland, the far north of england, but less cold, milder for northern ireland in towards wales and the south west. but here, we have more of the cloud, outbreaks of rain, which will be slowly spilling northwards and eastwards through

the course of the day. quite a bit of cloud for most of england but the far north of england, scotland off that cold, frosty start, will be dry and sunny throughout the day. maybe just the odd wintry shower around, some patchy cloud, but it will be windy, particularly across the northern half of the country, as you can see here. these are the mean wind speeds. so, when you factor in the wind with that cold air, it really will feel chilly — colder than these temperatures suggest, 3—5 degrees in the north, seven to maybe 11 degrees across the south and south west. now, as we head through christmas day evening, it looks like the rain will start to push its way northwards and eastwards and overnight, as it bumps into that cold air, we could see a bit of snow for north wales on the hills first and then into northern england, central, southern scotland, mainly over the pennines, across the southern uplands and the higher ground of central scotland. quite a covering here, maybe even some down to lower levels for a time. you can see it's going to be another cold night here, less so further south and west. so, some places on boxing day starting off with that snowfall across the north pennines, into the southern uplands, perhaps into central scotland but through the day, any snowfall will become reserved to the hills of northern scotland as the milder air begins to push its way northwards.

quite a lot of cloud generally across the country. we could see some brightness, a few showers pushing into northern ireland, wales and the south—west quadrant of england, where it'll be mild again but still chilly across the far north east. then, as we move out of boxing day to the run—up to new year's eve, we can see some really mild air starts to move in and right across the uk on a south—westerly wind, pushes all that cold air well away from the uk, so, it turns mild or even very mild for a time in places in the run—up to new year's eve. but with that, it will be unsettled, some areas seeing some spells of wet and windy weather.

this is bbc news. the headlines: millions around the world face travel disruption over christmas, as the surge in omicron variant cases sees thousands of flights cancelled due to staff shortages. united airlines says it's contacting those passengers affected before they arrive at the airport. china and the us are the worst affected countries. christmas celebrations have taken place in bethlehem, culminating in a mass at the church of the nativity, built at the site where jesus is said to have been born. earlier, in his christmas eve mass, pope francis called for more solidarity with those living in poverty around the world. and final preparations are under way for the launch of a rocket carrying a space telescope that could transform our understanding of the universe. the rocket carrying the james webb space telescope will take off from french guiana later on saturday. it's the successor to the hubble space telescope. now on bbc news, review 2021, the year in politics.
