as they take part in earth hour, to raise awareness of environmental issues. hello i'm nicky schiller — welcome to the programmme. we start this hour in russia. president putin says all those involved in the attack on a concert hall near moscow — which killed at least 133 people — will be punished. this is the scene live in moscow where people have been leaving flowers in memory of those who died and we've seen candles being lit. others have queued to donate blood for the victims of the massacre. memorials also appeared outside russian embassies in several countries, including the uk. a national day of mourning has been declared for sunday. armed police have been patrolling the area around the crocus city hall. in a televised address, president putin called the attack a �*barbaric terrorist act,�* and said all four gunmen had been detained.

the islamic state group says it carried out the attack and released a photograph of four masked men. our first report is from our russia editor, steve rosenberg who has been to the scene, and a warning, you may find some of the details in his report, upsetting. it was hard to believe that only yesterday this was a concert hall in what was left of crocus city, the full horror of what had happened became clear. the attackers had torched the building. a rock concert became an inferno. gunfire. screaming. but first the gunmen had opened fire... screaming and gunfire. to kill as many of the audience as possible. in one constant stream of bullets. russia says the four gunmen who did this have been arrested. and claims they plan

to cross into ukraine. kyiv denies any connection to the attack. it islamic state that's claimed responsibility. president putin promised vengeance. translation: all the perpetrators and organisers of this crime - and those who ordered it will be justly and inevitably punished, whoever they are, whoever is guiding them. those terrorists, those terrorists, murderers, monsters face the same and enviable fate, retribution and oblivion. in moscow, there were long queues to donate blood for the many who'd been wounded in the attack and rushed to hospital. outside crocus city hall, a hint of the devastation inside. the first thing you notice here isn't the site of the building, it's the smell. the air is thick with smoke because the concert hall was burning all night. the next thing you notice is what is happening over there,

people are bringing flowers, creating a makeshift shrine to the dead. margarita knows she is lucky. she was in the building when the shooting began and got out alive. translation: when i got home, i hugged my children. _ fell to my knees and said, "i can't begin to describe what happened there, they were shooting at us". i was hysterical, my husband could barely watch. the children were terrified, theyjust hugged me. but so many died here. there were so many victims of the deadliest attack in russia in 20 years. president putin has declared a national day of mourning. steve rosenberg, bbc news, moscow. as we've been hearing, the islamic state group has said it was behind the attack, but president putin says the gunmen were trying to flee to ukraine.

that's an allegation kyiv has described as �*absurd'. so what do we know about who may have launched the attack? here's our security correspondent, gordon corera. chaos and confusion as gunmen begin shooting inside the concert hall at crocus city. this footage, verified by the bbc, shows the gunmen in the foyer. but who are they? isis, the group calling itself islamic state, today issued a statement saying its men seen here were responsible. that's not something we can independently confirm. and the issue of who was responsible is deeply contentious. more than two weeks ago, the us issued this warning to its citizens in moscow, saying what it called extremists, thought to mean isis, might target large gatherings, including concerts. it communicated the intelligence directly to moscow.

but three days before the shooting, a kremlin statement was issued in which vladimir putin dismissed that warning, describing it as provocative and an attempt to destabilise russia. the russian security services say they stopped this car and that the four men involved in the attack have been arrested. but rather than say anything about isis, the kremlin suggested they were heading away from the scene and towards ukraine. that might be an attempt to deflect blame there and away from moscow. one of russia's tv channels even broadcast this last night. a fake video of a top ukrainian security official suggesting ukraine was involved. bbc verify has established two different videos were put together to make this with the words most probably generated by artificial intelligence. after any attack, there are always questions about whether it could have been stopped.

but in this case, those questions look especially difficult for moscow. gordon corera, bbc news. more analysis on the bbc news website. there's been an outpouring of support for the princess of wales, after revealing she's receiving treatment for cancer. in a video statement, catherine said the diagnosis came as a "huge shock," and that she's in the early stages of chemotherapy. health leaders have praised kate for being "brave" in "speaking out" about her diagnosis. kensington palace, says it's confident the princess will make a full recovery. let's go live our correspondent, charlotte gallagher who is at windsor castle for us. speaking to people here today, whether locals or tourists, they have been shocked by the news and also catherine's three children and the fact she will have to tell the three children about the diagnosis

and there is a warm feeling to the princess of wales. this is where they live, their home a mile from here inside the grounds of windsor castle and obviously where they feel at peace, their sanctuary. people leave them alone. it is their community. so people send them good wishes to catherine hoping as she said, she will be left to recover and have her treatment and peace. our royal correspondent has been looking at the events over the past few days. this is the national with erica johnson. catherine, the princess of wales made a shocking announcement. the impact of the princess diagnosis has been felt far and wide. her video message was the most direct and personal we have ever seen the princess. there was also an attempt to shut down the rumours that have created so much noise in recent weeks. i think what the princess of wales

is hoping is that this message will be direct enough to appeal to people's better nature's and say, the invasion of privacy that has been going on on social media for the last couple of months has been too much, people need to stop and think and not engage in that kind of activity going forward. family has rallied around the princess, including those with whom relations are strained. the duke and duchess of sussex sent a public message of support. the bbc understand that harry and megan have reached out privately. in windsor today, where the prince and princess live, public sympathy remains strong. we have been thinking of her all along and wish her the best. they are going through something so private and hard in the public eye on it, it is really tough, to be honest. she has got young kids . and she is a human being. i i thought it was all quite upsettingl and hopefully now they can get a bit of privacy as she heals. protecting her three children has been a priority for the princess of wales. she said she has taken time to

explain what is happening to george, charlotte and louis. and reassured them that she's going to be ok. i think it is important when tyrants are approaching talking to the i think it is important when parents are approaching talking to the children about their cancer diagnosis that they plan it, think about it carefully and also they get the right support to help them deal with the emotions it creates in them and that helps them to do it as well as possible. christmas at sandringham, the last time we saw the princess with the rest of the royal family. the next major gathering of royals will be on easter sunday. the king is hopeful of attending church in windsor that day. but the princess and her family will not be there, as she now recovers privately. daniela relph, bbc news. what the royal family will be hoping is that some of the only conspiracy theories that spread like wildfire over the past few weeks died down. it has obviously been a terribly

tough time for the princess. she has had to face up to being diagnosed with cancer, having to tell her family with her three young children and also there have been these conspiracy theories that have been promoted on social media with people with large following. going out to millions of people. so the princess and the entire royal family will i am sure he hoping that the news of her diagnosis puts a stop to that and now the focus will be on her recovery and getting that treatment. on that, there have been well wishes from around the world, have their not? , ., ._ from around the world, have their not? , ., i. not? yes. even here today you meet --eole in not? yes. even here today you meet people in windsor _ not? yes. even here today you meet people in windsor from _ not? yes. even here today you meet people in windsor from across - not? yes. even here today you meet people in windsor from across the i people in windsor from across the world coming to see the castle, from japan, to brazil to america expressing their good wishes to the princess. and then also world leaders. he was presidentjoe biden and his wife, expressed their wishes to catherine saying how much they loved her. french president macron expressed his wishes, the prime minister of australia. most

countries, leaders have said something about the princess and what she's going through at the moment. here in the uk, prime minister rishi sunak and the opposition labour party leader sir keir starmer passed on good wishes as well. it has been the conversation of the day when you speak to people here. people are in such a shock is the word about the news. no one would have expected when the princess went in for surgery injanuary when the princess went in for surgery in january that this would be the result. i think the video of her speaking to the world and telling them about her diagnosis has touched so many people. she was obviously emotional and seemed very vulnerable and once people are saying how much it upset them seeing that video and thinking about her three children as well. we that video and thinking about her three children as well.— three children as well. we saw prince william _ three children as well. we saw prince william out _ three children as well. we saw prince william out during - three children as well. we saw prince william out during the l three children as well. we saw - prince william out during the week, but he is now going to withdraw from public offence over easter to be with catherine and his children. you will imagine — with catherine and his children. you. will imagine they will be spending a lot of time at their home not too farfrom here in adelaide college. lovely grounds here, lots of woodland and you would think they

will be trying to do things as a five. the two parents and three children at home or out in the countryside trying to slow down and not to as many as those public offence as prince william is often out doing going out meeting people. this is a time for the family to come and heal. let's speak to caroline aston, she's a royal commentator for her majesty and shejoins me now. thank you forjoining us. i wondered if i could get your reaction to her video? i if i could get your reaction to her video? ~' , ,., , if i could get your reaction to her video? ~' , , ., . video? i think everybody watching this will either _ video? i think everybody watching this will either know _ video? i think everybody watching this will either know someone - video? i think everybody watching this will either know someone or. this will either know someone or sadly, themselves sat opposite a doctor in her that six letter word, cancer, that strikes chill in fear into our hearts. unfortunately the princess of wales has been the subject to so much tasteless and baseless commentary going on on social media. but at last she has

spoken to us all told us exactly what has happened and i sincerely hope she has no left to fully recover and come back and carry on doing thejob that recover and come back and carry on doing the job that she has done impeccably since she married into the royal family in 2011. impeccably since she married into the royalfamily in 2011. she has built herself a real place in our hearts and i am sure everyone watching this will wish her well, a speedy recovery and that the family gather around her and give her some privacy. gather around her and give her some riva . ~ , ., gather around her and give her some riva .~ , ., ~' gather around her and give her some riva .~ , ., ~ privacy. why do you think there was so much of — privacy. why do you think there was so much of this _ privacy. why do you think there was so much of this social _ privacy. why do you think there was so much of this social media - so much of this social media speculation and wild theories around the princess? i speculation and wild theories around the princess?— the princess? i would say it is a void or a _ the princess? i would say it is a void or a vacuum, _ the princess? i would say it is a void or a vacuum, people - the princess? i would say it is a void or a vacuum, people will. the princess? i would say it is a l void or a vacuum, people will try to fill it. of course we were given the bare minimum of information by kensington palace of a protracted recovery, complex abdominal surgery, at that time of course, described as noncancerous. the cancer diagnosis

only came after successful surgery. of only came after successful surgery. of course then we were left hanging in the air. so people started putting forward all sorts of theories about cosmetic surgery, there was even on debate about the state of their marriage. i would like to say this. we all know that recovery from surgery is traumatic, difficult physically. but if you add in the mental burden of having this tsunami of commentary, controversy and conspiracy theory going on, my goodness, poor princess of wales. let's hope her brave statement on camera to us all has the effect, oil on troubled water in this storm dies down and she is left to go forward and come back to us. later than easter which is when she was supposed to come back, but comes back fully recovered and continues to do sterling work.—

as well as her own engagements and going forward, there will be a lot of planning and replanting just to fill up the gaps. i am sure as we approach easter which is of course a time of new life, new birth and hope, that we all echo the words of the princess of wales. keep the faith, have hope. you are not alone. and ma'am, you are not alone either. the world, all of us are right behind you on this one. thank you very much — behind you on this one. thank you very much for— behind you on this one. thank you very much forjoining _ behind you on this one. thank you very much forjoining us. - to the middle east next. the united nations chief, antonio guterres has visited the rafah crossing and has made a renewed call for an immediate ceasefire in gaza. he said it was time to silence the guns and stop the nightmare — describing the ongoing loss of life there as a moral outrage. hundreds of trucks waiting are waiting at the border crossing to bring much needed aid into gaza. mr guterres' visit comes as israel faces mounting international pressure to allow more goods into the territory, as fears mount of imminent famine.

nothing justifies the horrific attacks by hamas on october 7th. and nothing justifies the collective punishment of the palestinian people. now, more than ever, it is time for an immediate humanitarian ceasefire. it is time to silence the guns. palestinians in gaza — children, women, men — remain stuck in a nonstop nightmare. communities obliterated, homes demolished, entire families and generations wiped out,

with hunger and starvation stalking the population. bringing you some live pictures from tel aviv in israel. this first set of pictures are antigovernment demonstrators on the move now. this is happened regularly on a saturday over the last few weeks where there have been antigovernment protests. this the latest of those. also on saturdays we see the families of the hostages that are being held gather in hostage square. this is where you can see the posters of some of the faces of the hostages that are being held by hamas in gaza. you can see another one there is saying bring them home now. this happens every saturday where the families join each other and call on the

government to do more to get the hostages out of gaza. so that demonstration taking place in tel aviv at the moment. here in the uk, the father of damilola taylor, who was killed aged 10, has died. richard taylor — who was 75 and seen here with the dark red tie on — had spent years campaigning for disadvantaged children richard taylor — who was 75 and seen here with the dark red tie on — had spent years campaigning for disadvantaged children after his son was stabbed to death, with a broken bottle, in 2000 in peckham in south london. he set up the damilola taylor trust to campaign against knife crime. now the human body is an amazing thing. i want to show you some pictures now of the moment a british runner made history by becoming the first woman to finish one of the world's hardest ultramarathons. jasmin paris, from midlothian, conquored the barkley marathons in tennessee with just one minute 39 seconds to spare of the 60—hour cut off. the gruelling mission covers 100 miles — or 160 kilometres — but with a mixture of climbs

and decents — that are 60 thousand feet or 18,000 metres — that's about twice the height feet or 18,000 metres. that's about twice the height of the mount everest. earlier we spoke to stephen cousins, an ultramarathon runner who has his own you tube station dedicated to the sport. earlier we spoke to stephen cousins, an ultramarathon runner who has his own you tube station dedicated to the sport and asked him about the marathon course. the race has been going for many years. 1989 was when it first became the 100 mile event. i should say, they say it is 100 miles, but it is more. there are five loops of a place called frozen head state park in tennessee. the park is a wild terrain. barbs cut into your legs. the climbs are very steep. if you finish all five loops, you will have not only could have covered well over 100 miles, possibly 120 or 130 miles, and if

you go wrong, even further, but you will have climbed essentially twice everest�*s height. it is a very difficult race to complete. since 1989, there have only been, until yesterday, 17 individualfinishes. just contemplate how many people finish the london marathon every year. 17 finishes across the entire spectrum of that event in all the years it has been going, and none of them have been a woman. it has all been men up until last night. jasmine paris became the first ever woman to complete the barkeley marathons. how do you prepare and train for something like that? i think, with anything, you have to start small and grow. jasmine started out fell running.

she is from derbyshire and she started out in the fells in derbyshire. learning to climb, learning to go hours and hours in the mountains. and she eventually developed, won some races, won a famous thing called the fellsman, then won one of the toughest races in the uk, a staged race over five days in wales called the dragon's back. she won that. that is another stepping stone along the route. then you may remember that in 2019, a lady won the spine race, which is 268 miles in the winter, along the pennine way. and this lady breast—fed her child — she expressed milk for her child at all the aid stations along the route. that was jasmine paris. she has learned, she has grown, she has trained hard in

races and, of course, you have to train every week and be consistent, building up your mileage, building up the strength and endurance in your body, to even attempt the barkeley marathons. there are some famous, well—rounded runners with huge amounts of experience who get one loop done of the barkeley marathons and then tap out and say, that was too hard. jasmine did all five loops. finally, have you tried it? you know what? i would absolutely love to give it a go. a friend of mine was actually in this year's barkeley marathons, someone i have run with, and he managed one loop. i would like to think, on a good day, i would get one done. it was a tight finish, wasn't it? amazing. i definitely would not ever try it.

some of the world's most famous landmarks have turned off their lights and been plunged into darkness — taking part in earth hour. the global event aims to raise awareness of environmental issues and the impact of climate change. here is the moment the sydney opera house in australia flicked the switch, in unison with the sydney harbour bridge. injapan — this is the tokyo tower having its lights switched off. a sight rarely seen — hong kong's victoria harbour and city skyline in darkness as part of the campaign. and here's bangkok s iconic temple of dawn, going dark. here in the uk we are expecting landmarks like big bend to go dark and about one hour's time. this is the thing live in paris where you

can see the eiffel tower is all lit up. those lights are set up to go off in the next five minutes or so. we will keep an eye on that. stay with us. hello, it was a day of dodging the downpours. some really heavy showers out there driven by some big storm clouds, including this one captured by one of our weather watchers in surrey, with this lumpy shape indicative of what we call mammatus clouds that form when the air is very turbulent, very unstable, and you can see that unstable air, all driven by an area of low pressure, allowing these big storm clouds to bubble up. a brisk north—westerly wind blowing those showers and storms through. the centre of our area of low pressure moving out into the north sea overnight. but still quite windy for northern scotland and eastern england and still some showers which will be wintry over high ground and clear spells elsewhere and because of the strength of the wind, it will not be

a particularly cold night but still getting down to around three or six degrees so that area of low pressure sliding away eastwards and very briefly a ridge of high pressure, which you can barely see on the chart, and there is then another weather system approaching from the west. so, for sunday it is really a window of fine weather with some showers and still some brisk winds down this east coast and still some showers at times in northern scotland and then through the afternoon, clouds thickening up across northern ireland and maybe some rain into western counties by the very end of the day and also perhaps into the west of cornwall and parts of pembrokeshire. not as chilly as it has been today, eight to 12 degrees, and then here comes this frontal system as we move on into monday but instead of sweeping through quickly, it sort of meanders and takes a time, it does dawdle, this weather front. so, not moving through quickly, in fact, rangers lingering across western england, wales, northern ireland and if the rain get into central and southern parts of scotland we could see some significant snow

over the high ground. we keep hold of some sunshine in the south—east corner, if that happens, we may get up to 12 degrees. by tuesday, we will be left in some relatively cold air so any showers we see in the north of the uk could be wintry over high ground and a slow—moving band of rain could sit over south—west england and the channel islands and it'll be a very wet day here and this temperature is no great shakes, seven to 11 degrees. as we head to the end of the week and into easter weekend, it looks very unsettled with bouts of rain and turning very unsettled particularly in the south but cold air may linger in the north of the uk.

this is bbc news. the headlines: four gunmen have been arrested after 133 people were killed in a moscow concert hall attack. president putin has vowed those responsible will be punished. the islamic state group says it was behind the attack, releasing a photo of four masked men it says were involved. an outpouring of support for the princess of wales, after she revealed she's in the early stages of cancer treatment. in a video statement, catherine said the diagnosis came as a "huge shock". health leaders have praised kate for being "brave" in "speaking out". the health ministry in gaza says the number of people killed by israeli forces while waiting for aid on the outskirts of gaza city has risen to at least 19.

the israeli army has denied firing on the crowd. you can get more on all of the stories on the bbc news website or app. about five minutes ago, i showed you pictures of the eiffel tower all lit up and we said they were due to go out to. let me take you back to paris and you can see that as the lights have all gone out on the eiffel tower and the rest of paris is still lit up there but you can just see the top of the eiffel tower there it up but the rest of it has gone. it is all part of earth day, the global event which aims to wear awareness of environmental issues and the impact of climate change. —— to raise awareness. we are expecting london icons like big ben to turn out their lights in around an hour's time. it is a view of london at the moment. you can see that
