when gunmen stormed the packed auditorium, minutes before a rock band was due on stage. president putin has suggested that four gunmen arrested on saturday were trying to flee to ukraine — a claim that's been strongly rejected by president vlodomyr zelensky. steve rosenberg reports and a warning you may find some of the details, distressing. in what was left of crocus city, the full horror of what happened became clear. the attackers had torched the building. the rock concert became an inferno. but first, the gunman had opened fire. to kill as many of the audience as possible. in one constant stream of bullets. russia says the four gunman who did this have been arrested. and claims

they planned to cross into ukraine. kyiv denies any connection to the attack. it is islamic state that has claimed responsibility. president putin promised vengeance. translation: fir promised vengeance. translation: or the perpetrators - translation: or the perpetrators and - translation: or 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, murderers, monsters, face the same fate, retribution and oblivion. in same fate, retribution and oblivion. a, , . ., oblivion. in moscow, there were lona oblivion. in moscow, there were long queues _ oblivion. in moscow, there were long queues to _ oblivion. in moscow, there were long queues to donate - oblivion. in moscow, there were long queues to donate blood - oblivion. in moscow, there were long queues to donate blood forj long queues to donate blood for the many who had been wounded in the attack and rushed to hospital. outside, crocus city hall, a hint of the devastation inside. the first thing you notice is not the size of the building, it is a smell. the air is thick with smoke because the concert hall was burning all night. the next thing you

country was involved. translation: one more thing, what happened in moscow - yesterday, it's obvious that putin and other scumbags are just trying to find someone else to blame. their methods are always the same — we have seen it all before, destroyed buildings and shootings and explosions and they're always looking for someone to blame. so what do we know about who was responsible? here's 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 communicates 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 verifies 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. let's speak to steven fish now, who's a professor of political science at the university of california. thank you for your time. before we get to the actual claims that president putin is making, what do you of the length of time it took for him to make a public statement? he time it took for him to make a public statement?— public statement? he was clearly very _ public statement? he was clearly very embarrassed l public statement? he was i clearly very embarrassed by this. we now know that western security agencies had warned russia, perhaps some weeks ago, that this was coming, and they either ignored it or were contemptuous with this information or used

ineffectively. what is facing now is a situation where he's been shown that western security agencies know more about what is going on in russia than his own security agencies do when it comes to confronting terrorism. this is a bad look for putin.- confronting terrorism. this is a bad look for putin. what do ou the a bad look for putin. what do you the wants _ a bad look for putin. what do you the wants to _ a bad look for putin. what do you the wants to point - a bad look for putin. what do you the wants to point the i you the wants to point the finger, he is pointing the finger, he is pointing the finger at ukraine rather than the islamic state group? look, what we saw — the islamic state group? look, what we saw in _ the islamic state group? look, what we saw in that _ the islamic state group? look, what we saw in that report - what we saw in that report shows just how crazy this is getting. i suppose the ukrainian government is now a jewish lead nazi fascist state, this is the world that president putin lives in. given what we saw in that report as well, this is crazy land! to the extent that putin pushes this an ukrainian tries to make it a story about ukrainian culpability, which is absolutely ludicrous, i think we have grounds to wonder whether he himself was involved in this attack. we have to remember that going back to 1999, when he was on his way to the presidency, there was a series of four very suspicious

apartment blasts. at the time, he had just become prime minister and he and his new security had, who was still his main security henchmen, it seems there is overwhelming circumstantial evidence that they actually blew up those apartment buildings to create a pretext for their war in chechnya and to rally public support around putin and his wall. i don't think this happen this time. the evidence looks like it is the isis—k group who did it but we know putin is not above this. he has done it before. we suspect very strongly he has, that he is actually engineered what he called and islamist terrorist act for its own political purposes. again, i don't think this happen here back to the extent he presses his son ukraine, you do have to wonder a bit. ., , a bit. those rumours did circulate _ a bit. those rumours did circulate and _ a bit. those rumours did circulate and there - a bit. those rumours did circulate and there was i a bit. those rumours did i circulate and there was that circumstantial evidence you were talking about, back then, something that putin and the kremlin have always denied. in

this case, what do you think about the security inside russia? putin would absolutely categorically deny the idea that he or the kremlin had anything to do with this. you mentioned that as a possibility. the us for its part has said from its intelligence, it does seem likely that this was the islamic state group. either way, putting aside he was behind it, what does this say about security inside moscow, and how one of the deadliest attacks in 20 years was even possible?— attacks in 20 years was even possible? the fact that putin would absolutely _ possible? the fact that putin would absolutely deny - possible? the fact that putin - would absolutely deny something probably means it is true in many cases! putin will lie even when it's easier to take that as tell the truth. the security situation in russia is not what it should be. the most embarrassing thing for

putin. . .. embarrassing thing for putin.... i embarrassing thing for putin...._ embarrassing thing for putin.... ., ., ., ., putin. . .. i do want to add, the united states _ putin. . .. i do want to add, the united states does _ putin. . .. i do want to add, the united states does say - putin. . .. i do want to add, the united states does say the - united states does say the intelligence points to islamic state group and it had warned moscow of this beforehand. that's right, and again that is a bad look for putin because this happened anyway despite the fact he was getting warnings. he was getting warnings. he was getting warnings from the west that this would happen and it looks like he did miss them. again, —— dismissed them. it is something that even enemy countries who used to help each other out, it should be honoured, this norm but the extent that putin will try to blame ukraine for this, which is ludicrous, or blame the united states or britain or anyone else, will be hard to imagine western security agencies sharing intelligence like this with russia under these circumstances. thank you for our these circumstances. thank you for yourtime- — there have been multiple explosions in the ukrainian capital, kyiv, following

russia airstrikes. the military said that air defence systems were engaged in repelling the attack. there have also been reports of loud explosions in the western region of lviv, near ukraine's border with poland. in a statement, the polish armed forces said poland and its allies had activated aircraft to ensure the safety of polish airspace. kensington palace has said the prince and princess of wales are enormously touched by the kind messages they have received following catherine's cancer diagnosis. it released a statement on saturday night which also added they were grateful that the public understood their request for privacy. catherine revealed in a video message on friday that she had begun treatment. here's daniela relph. this is the national with erica johnson. catherine, the princess of wales, made a shocking announcement... making headlines globally... kate middleton...

..the impact of the princess's diagnosis has been felt far and wide. her video message was the most direct and personal we have ever seen the princess. this, of course, came as a huge shock... it was also an attempt to shut down the rumours. i think what the princess of wales is hoping is that this message will be direct enough to appeal to people's better natures and say, look, the invasion of privacy that has been going on, on social media for the last couple of months has just been way too much. people need to stop and think and not engage in that kind of activity going forward. and now a fresh statement from kensington palace, a public thank you. it said...

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 understands they have also reached out privately. public sympathy remains strong. we've been thinking of her all along and wish her the best. they're going through something so private and hard and, you know, the public eye on it, it's really tough, to be honest. yeah, she's got. young kids, right? and she's a human being, so i thought it was - all quite upsetting. protecting her three children has been a priority for the princess of wales. she said she's taken time to explain and reassure george, charlotte and louis. the new message from the prince and princess is both a thank you and a polite warning. they now want to be left alone. we do not expect to hear from them over the easter holiday. instead, we may see the king

backin instead, we may see the king back in the royal spotlight. christmas at sandringham, the last full gathering of the royal family. next sunday, many will be back for the easter church service in windsor. buckingham palace are hopeful that the king will also be there. daniela relph, bbc news. united nations secretary general antonio guterres has visited the rafah border crossing and has made a renewed call for an immediate ceasefire in gaza. his call comes as the hamas—run health ministry in gaza said 19 people waiting for aid were killed by israeli forces. israel has denied firing on the crowd. mr guterres said it is time to silence the guns and stop the nightmare, describing the ongoing loss of life in gaza as a moral outrage and called on israel to give total, unfettered access to humanitarian goods throughout the territory. it's time to truly flood gaza

with life—saving aid. the choice is clear — either surge or starvation. let's choose the side of help, the side of hope, and the right side of history. our middle east correspondent, hugo bachega, is near the rafah crossing. he sent us this update on efforts to get aid into gaza. this is the egyptian side of the rafah crossing with gaza and one of the main entry points for humanitarian assistance into the territory. here, hundreds of trucks are waiting to be allowed to enter gaza. now, western officials, aid groups, have been criticising israeli authorities for this inspection process. they say that it's been extremely slow and they say that some of these trucks have been turned away because they have been carrying some items that have been banned by the israeli authorities, such as medical scissors and also

sleeping bags. now, some of these trucks have been here for weeks waiting for these inspections and the un says more than 1,500 trucks are waiting here in egypt and obviously the humanitarian situation in gaza is worsening. today, antonio guterres is back here. the un chief is again calling for a humanitarian ceasefire in gaza and for israeli authorities to do more to allow more humanitarian aid into gaza. this visit happens just days after an un—backed report said half of gaza's population of 2.2 million people faced catastrophic levels of hunger and that famine in northern gaza was imminent if there was no pause in fighting and a surge in aid. dr sherifa zuhur is director of the institute of middle eastern, islamic, and strategic studies.

thank you for your time. israel has consistently pushed back against the un warning that others are taking note and the economist cover says is israel alone. would you agree with that statement?— that statement? no, unfortunately. - that statement? no, unfortunately. i- that statement? no, | unfortunately. iwould that statement? no, - unfortunately. i would say unfortunately. i would say unfortunately quite a few western countries have supported israel to this point that we have what the un chief is calling a man—made famine and a catastrophic situation in gaza. although we know it is catastrophic, international organisations and international calls are not working.—

calls are not working. israel is insisting _ calls are not working. israel is insisting the _ calls are not working. israel is insisting the measures i calls are not working. israel is insisting the measures it | calls are not working. israel. is insisting the measures it is taking are necessary in its war against hamas following the brutal attacks of october seven. having said that, allies are pushing back. what you make of what the us secretary of state said on his recent visit. what does it say about the relationship between the us and israel right now? the relationship between the us and israel right now?— israel right now? the problem is this state _ israel right now? the problem is this state department, - israel right now? the problem | is this state department, under antony blinken and president biden, have steadfastly defended israel and funded israel and recently through congress, continued to arm israel. at the same time, gradually stated there is an emergency and we are pushing on israel and we want israel to be reactive to our requests, but they are not, they are not

exerting any pressure against the country so it would react. secondly, there is this measure in the un, here is the chief of the un telling us how dire the situation is and there is a measure that the us put forth in the un after several very serious ceasefire efforts, which is not serious. which does not demand a sincere ceasefire. i'm one the many americans who cannot support the administration in this policy. oli . , ., oli. , ., ., oli . , ., ., ., policy. they would argue that israel is an _ policy. they would argue that israel is an ally _ policy. they would argue that israel is an ally and _ policy. they would argue that israel is an ally and they - policy. they would argue that israel is an ally and they are l israel is an ally and they are working towards the release of hostages as well is getting more aid into gaza. what do you make of the efforts to secure a ceasefire right now? are you hopeful we could see one? i don't know. the us sponsored

resolution which will come again was previously vetoed by russia and china and the problem with that is it does not categorically call for a ceasefire. and that is what we need. of course, a release of hostages. and a release of prisoners. so these are the different sides and the demands. there is not only one side. even though a country is our ally, an ally of the us and the uk, sometimes tougher talk needs to be made to an ally. what is happening now is not defensible from anywhere in the world. ., ~' ,, defensible from anywhere in the world. . ~ ., .,

where a number of buildings including the empire state building dimmed the lights. here is the moment the sydney opera house, in australia, flicked the switch, in unison with the world—famous harbour bridge. a sight rarely seen, hong kong's victoria harbour and city skyline in darkness as part of the campaign. here in london crowds gathered as the giant electronic advertising boards in piccadilly circus went dark as well as the houses of parliament and the clock tower which houses big ben. and greece's most famous monument, the parthenon temple, and the other temples on the acropolis in athens, were in darkness as the lights were switched off. the event which started in 2007 has grown every year with more capitals around the world taking part. there have been multiple explosions in the ukrainian capital, kyiv, following russia airstrikes. the military said that air defence systems were engaged

in repelling the attack. stay with us here on bbc news. hello there. well, it's certainly been a lively start to the weekend weatherwise. loads of showers around on saturday, some of them with hail and thunder, some of them with mammatus clouds — always a sign of a good storm. now, the showers that went through south parts of greater london, around kent, they really dumped the temperatures. look at that — ten degrees at midday, just two degrees celsius a couple of hours later in the afternoon. that would have felt really cold, especially with those gusty winds. now, over the next few hours, many of the showers will tend to become confined to more northeastern areas of the uk should become drier over the next few hours in the west. temperatures as we head into the first part of sunday morning, quite chilly around 3 to six degrees celsius. now, sunday will continue to be dominated weatherwise

by this area of low pressure — it's the same one that we had on saturday, but it's starting to pull away into the near continent, but still influencing our weather. certainly there'll be lots of showers across northern areas of scotland and a few affecting the east coast of scotland running down east and coastal counties of england as well. some of the showers for these areas will continue to be quite heavy with some hail, whereas across western areas of the uk many areas should have a dry day with some bright or sunny spells. temperatures for most about 10 to 12 degrees — that's average for the time of year. northern scotland, about six to eight. that's a little on the cool side. then into monday, we get another area of low pressure forming and moving in off the atlantic. this is going to be bringing further outbreaks of rain on monday to northern ireland, wales and western areas of england. probably a dry and bright day for eastern areas of england. the rain starts pushing northwards across scotland and starts to move into the chilly air that we have here. temperaturesjust six in aberdeen. so through monday night we might actually start to see some of that rain turn to snow. it is going to be quite high up

in the high hills of scotland, probably above 300 metres elevation or so, but that could continue to be a risk into tuesday. so you might see a little bit of snow on some of the very high—ish scottish routes in the north. otherwise at lower elevations it's just outbreaks of rain, sleet and a bit of hail that you'll see mixed in. a cold day on tuesday — temperatures around nine or ten for england and wales, just five there in aberdeen. so overall, we're looking at a very unsettled week ahead, a cold start to the week, yes, but it does tend to turn milder as the week goes by. bye for now.

this is bbc news, the headlines: a day of mourning in russia after friday's deadly attack on a concert hall near moscow — killed at least 133 people. russia's vladimir putin promised vengeance on those involved in the attack, claimed by the islamic state. he says all four gunmen have been arrested. the prince and princess of wales say they are "enormously touched by the kind messages" received following catherine's video announcement she is being treated for cancer. the statement from kensington palace also added they were "grateful" that the public understood their request for privacy. and it's lights off for major landmarks as they flick the switch to take part in earth hour. the global event aims to raise
