prince harry and meghan have also sent a message wishing health and healing for catherine and the family. and in the middle east, the un secretary—general is preparing to visit the egyptian—gaza border to call again for a humanitarian ceasefire. israel is under mounting international pressure to allow more aid into gaza, amid warnings of imminent famine. at least 115 people are known to have been killed when gunmen opened fire on crowds at a concert near moscow. over 140 others were injured. the islamic state group has claimed responsibility for the attack at the crocus city concert hall. four people involved in the attack are among 11 detained,

by the fsb. we are going to show you some live pictures of that concert hall. you can see the various media gathered there as well. people have been leaving floral tributes. you cannot see that. certainly, if you had to the bbc news live page, you will see some of those tributes and you will see what our security vehicles that are around the crocus concert hall. that back section is the area that was affected in that terrorist attack. four gunman entering and damaging the roof. the roof than

collapsed. we are getting more insight into what it looks like inside that charred black section. i am going to take you to the bbc news live page. if we scroll down, steve rosenberg is giving his update of the scents and smell of the building. the floral tributes. further down this page, we start to see that distraction —— the disruption inside the hall. the roof collapsing after the building were set on fire. the next image showing emergency responders showing up metal structures used to hold up the walls. skeletons of seeds also in the next shot, that is all that remains of the concert hall. as the

emergency services have entered that area, that is why the death toll has started to climb. up until now it has been too hot and too dangerous to enter. earlier, i spoke to our eastern europe correspondent sarah rainsford, who is in kyiv. i asked her what the fsb has been saying about the attack in moscow. this was a long statement from the fsb about the attack, about their theories and their investigation. but the kind of crunch line, if you like, for ukraine came towards the end when this statement said that the suspects, those suspected of carrying out this attack on the crocus city mall in moscow had then fled the scene and that they were heading towards ukraine. and according to this statement, the fsb said that they were planning to cross the border into ukraine and that they had contacts here on the ukrainian side. now, i'vejust spoken to a spokesperson for military intelligence here in ukraine, and he has called that absolutely absurd.

he made the point quite clearly that that area, specifically on the border with ukraine between ukraine and russia, the region that was referred to by the fsb, is absolutely full of intelligence security services, full of military at the moment. there's an ongoing military operation. there is an active frontline in that area. we were on the other side of the border just the last couple of days. there are people fleeing from that border area. so it's an active military area. and he said that to suggest that terrorists fleeing a terrorist attack would head to specifically that region would suggest they were either idiots or suicidal. so ukraine very quickly dismissing any suggestion that this is linked to ukraine, that ukraine was in any way involved. but certainly since the very beginning, there have been fears here in ukraine that russia would try to point the blame somehow towards ukraine as an excuse for escalating its war on this country, which, of course, has been devastating ukraine now

for more than two years. yeah. what did ukraine have to say on this? because i understand doleac, who is a top adviser, had had made a video statement. what did he say in response to those accusations? yes. we heard from the presidential adviser, michael polak. we also heard from the foreign ministry late last night, as this news was coming in from moscow. there were statements from defence intelligence as well. so lots of very quick statements from here in ukraine absolutely categorically ruling out any link whatsoever to the attack in moscow. he talked about what he said. he said ukraine is fighting russia on the battlefield and that is where the war will be fought and ukraine says will be won. he also said that ukraine would not be involved in this kind of attack on civilians inside russia. he ruled it out. absolutely, as i say, so did the foreign ministry here. but, you know, there

were a lot of people worried because when they were watching that news coming in, you know, the real fear here is that russia is looking for an excuse to escalate things — looking for an excuse — particularly, i think the view here in ukraine is to rally support around this war, to boost support for vladimir putin's war on ukraine, in order, ukraine believes, to get more soldiers to sign up for the cause — in order for vladimir putin to be able to announce a general mobilisation of the population so that he has more soldiers to continue prosecuting his war. that is the fear, the worry here in ukraine, because, of course, that would mean even more missile attacks, rocket attacks, military activity, which has huge and devastating consequences for people here in this country. that was sarah raynsford. steve rosenberg has sent this update from outside the concert hall in

moscow. behind me is crocus city hall. the air was thick with smoke. it was burning all night. it is one of the most famous concert venues in russia. yesterday became a bloodbath when gunman went on the rampage, killing dozens of people and leaving russia in shock. throughout the morning, russians have been arriving, bringing hours and trying to comprehend what has happened here. among the people here are russians, who saw the news on television and thought they had to come. people who had friends here yesterday. also people who are here themselves, during the shooting. spoke i to one woman who recounted her nightmare, the nightmare she went through. she told me she

managed to get out and the first thing she did when she got home was to hug her children tight. we thing she did when she got home was to hug her children tight.— to hug her children tight. we will aet all the to hug her children tight. we will get all the latest _ to hug her children tight. we will get all the latest as _ to hug her children tight. we will get all the latest as and - to hug her children tight. we will get all the latest as and when . to hug her children tight. we will get all the latest as and when it | get all the latest as and when it comes in. earlier, i spoke to sergei markov, a political ally and former adviser to the russian president vladimir putin. it isa it is a very strange attack. usually they take hostages and make some demands and also for mediation. here it was another style. if you peoplejust mediation. here it was another style. if you people just came and killed about 100 people. they left. and now they have been captured, nearby the border of ukraine. in russia it is almost clear this

attack was from islamists. but from ukrainian territory. the question, the decision about a terrorist attack had been made in ukraine. it is small groups on the ground. the military intelligence of ukraine has remained under suspicion. if military intelligence of ukraine has remained under suspicion. ii the remained under suspicion. if the russian government _ remained under suspicion. if the russian government was - remained under suspicion. if the russian government was aware there are terrorists operating in certain regions, why would they, why weren't they monitoring them? how is it this attack managed to slip through and essentially kill russian citizens? isn't it down to the russian security system?— isn't it down to the russian securi s stem? ,, , _ security system? the us embassy ublicl security system? the us embassy publicly told _

security system? the us embassy publicly told there _ security system? the us embassy publicly told there was _ security system? the us embassy publicly told there was possibility| publicly told there was possibility of an attack in moscow, around march the 8th, woman's day in russia. they celebrate. now information has come that this terrorist attack was planned on march the night, in exactly the same concert hall where the concert was of a famous singer and also who is public spokesman for vladimir putin during this election campaign. first of all the terrorist attack had been planned, it was march the night. after this information, russian security make a lot of measures. two terrorist groups have been arrested. this terrorist attack which was planned

on march the 9th. after it is impossible to have endlessly strong level of their security measures. after one week, ten days, this attack had been conducted. former adviser to vladimir putin. let's turn to the middle east now. the un secretary—general, antonio guterres, will renew his call for a humanitarian ceasefire in gaza during a visit to egypt today. he will go to the rafah border crossing, where hundreds of lorries on the egyptian side are waiting to take basic aid into gaza. israel is still under mounting international pressure to allow more aid into gaza. and that's amid warnings of imminent famine. meanwhile, russia and china have blocked a us draft resolution that tied an immediate ceasefire in gaza to the release of hostages held by hamas.

the two countries said the text put conditions on a pause in the fighting — and failed to clearly oppose a planned israeli ground offensive in rafah. the first british field hospital has been set up in gaza, and is aiming to be fully functioning early next week. the hospital was sent by truck from manchester to provide life—saving medical treatment for the sick and injured in gaza. it has been established by a team from the aid organisation, uk med, which deploys many nhs staff to emergencies. uk med already has surgical teams working in the al aqsa hospital, the only hospital still functioning in the centre of the gaza strip. from jerusalem, our senior international correspondent 0rla guerin sent this report. wheeled through the chaos. 12—year—old anas, another young victim of israel's assault on gaza.

he's on his way to surgery in al aqsa hospital. a team from uk med standing by. so we got a patient with the femoral fracture — he is a very brave boy. so let's go. it's me, anas. anas says he was playing when his neighborhood was bombed. he was injured and his mother and six—month—old baby brother were killed. "may god have mercy on their souls", he says. the surgery goes well. it's one of hundreds the team have performed at the hospital, where they've been faced with desperate need and some of the worst that war can do. i've worked in many war zones over

the past nine years, and i think what shocks me about this particular context is the number of children injured that we are seeing and the extent of those injuries, they are life—changing injuries that a child will have to live with. with gaza's hospitals overwhelmed, and sometimes under israeli attack, the uk team have been building a new facility. it's in the desert sands north of rafah. they got started with local timber from destroyed buildings when their field hospital was held up at the border. it took a lot of negotiation to get land. negotiation to get things across the border. it's been a challenge to find staff. it's been a challenge to communicate. none of the phones work, none of the internet works. and everything somehow has to be made to work in order to bring essential, urgent lifesaving services to people. they are already seeing about 100 outpatients a day here and expect to double that soon.

the doctors are ready to treat everything from minor illnesses to gunshot wounds. and, if israel carries out a ground invasion of rafah, as it's threatening to do, this field hospital could be crucial. 0rla guerin, bbc news, jerusalem. 0ur correspondent mark lowen is injerusalem with more on the un secretary general antonio gutterres�*s trip to the middle east. he's at al—arish today, which is the border crossing very close to the border crossing between egypt and gaza, where he will be seeing the aid shipment that is stacking up there on the border and which is waiting to come in. and frankly, not enough of it has come in because israel has restricted aid by trucks getting into gaza by either by restricting

entry points actually of the aid trucks coming in or indeed by performing lengthy and cumbersome checks on the trucks which have slowed down aid deliveries in now. israel rejects that claim by saying that it is hamas that has disrupted aid efforts and that the un has been too slow to distribute it. but all the aid agencies on the ground have reported that in that it is israeli checks and the lack of entry points, which is the principal reason why they're why there's just about a fifth of the daily deliveries into into gaza that is actually needed. he will also be talking to medics, working at hospitals right on the border, and he will be examining the sort of the attempt to get more aid in. he will presumably also be calling for restraint from israel in terms of actually sending its military into rafah on the other side of that border crossing. yesterday, benjamin netanyahu met

the us secretary of state, antony blinken in tel aviv, who again urged israeli restraint. but those warnings overtly or apparently appear to be falling on deaf ears because mr netanyahu said that after that meeting, if the us does not support us, we will go it alone, we will do it alone and we will send the israeli military into rafah in defiance of all the international warnings about the fate of some 1.5 million civilians, who are sheltering there. and just very quickly and whilst all this is going on, of course, the talks in qatar continue. who's involved in that? and what is the alternative to the proposal that was put forward by hamas? what are they fighting for, trying to agree on? there's an israeli delegation led by the head of mossad, israel's intelligence service. there is bill burns, who is the head of the cia, and there are senior officials from qatar and egypt, the regional negotiators. the alternative, according to the us, which so far we know, is to basically cut off the smuggling routes from egypt into gaza to basically choke off hamas's supply of weapons and funds. but israel does not see that

as a viable alternative. israel, as well as attending those talks in doha, is sending a delegation to the us next week to hear the americans plea for an alternative to this invasion of rafah. at the moment, though, those peace talks in doha don't seem to be making a breakthrough. and there is still there is still a chasm of mistrust —— and there is still a chasm of mistrust and plenty of differences between the warring sides, which means that nobody expects an imminent breakthrough in those talks. let's return now to the news that the princess of wales is undergoing treatment for cancer. catherine revealed the diagnosis herself, in a statement recorded on wednesday at windsor castle. i wanted to take this opportunity to say thank you personally for all the wonderful messages of support and for your understanding whilst i've been recovering from surgery. it has been an incredibly tough couple of months for our entire family. but i've had a fantastic medical team who've taken great care of me for which i'm so grateful.

injanuary, i underwent major surgery in london and at the time it was thought that my condition was non—cancerous. the surgery was successful, however, tests after the operation found cancer had been present. my medical team therefore advised that i should undergo a course of preventative chemotherapy, and i'm now in the early stages of that treatment. this, of course, came as a huge shock, and william and i have been doing everything we can to process and manage this privately for the sake of our young family. as you can imagine, this has taken time. it has taken me time to recover from major surgery in order to start my treatment. but most importantly, it has taken us time to explain everything to george, charlotte and louis in a way that's appropriate for them, and to reassure them

that i'm going to be ok. as i've said to them, i am well and getting stronger every day by focusing on the things that will help me heal — in my mind, body and spirits. having william by my side is a great source of comfort and reassurance, too, as is the love, support and kindness that has been shown by so many of you. it means so much to us both. we hope that you'll understand that as a family we now need some time, space and privacy while i complete my treatment. my work has always brought me a deep sense ofjoy, and i look forward to being back when i'm able. but, for now, i must focus on making a full recovery. at this time, i'm also thinking of all those whose lives have been affected by cancer. for everyone facing this disease, in whatever form, please do not lose faith or hope. you are not alone. earlier i spoke to the royal

commentator, pandora forsyth. she and her family, she and herfamily, despite being on the worldwide stage and under scrutiny for the past few months may need space, time and proceed to recover and go through this preventive chemotherapy, which i am sure many of us can understand. if anyone had questions as to why we weren't seeing her and all the theories online, i hope this has put a stop to this. you theories online, i hope this has put a step to thie— a stop to this. you know how much attention the _ a stop to this. you know how much attention the royal _ a stop to this. you know how much attention the royal family - a stop to this. you know how much attention the royal family does . attention the royal family does attract. what sort of work do you think the royal household and the media team will be doing to try to give her the space to recover? i think the fact this was evidently very heartfelt video, not an image or a statement. they were well

within their rights to release a statement about this instead. i think the reason why they have shown a video is so people can stop the speculation and hopefully this will have done theirjob in stopping, as they said in their own words, kensington palace, the social media madness which has surrounded it all. of course, people are concerned of course, people are concerned about the princess of wales. 3 million people in the uk are living with cancer. there will be questions. now it's time to step back and stop asking so many questions to their pr and communications team, which had been under heavy spotlight with the manipulation imagery which came out. this video, because it is so heartfelt a shot in windsor on wednesday. it is very open, despite

talking about very difficult and personal circumstances. he mentioned a coule of personal circumstances. he mentioned a coume of points. _ personal circumstances. he mentioned a couple of points, the _ personal circumstances. he mentioned a couple of points, the number- personal circumstances. he mentioned a couple of points, the number of- a couple of points, the number of questions that were asked and i hope those will now stop. ultimately, princess catherine in the royal family have a duty to the united kingdom but they also have a duty to their children, they are a family. what do you make of the timing of the statement? it what do you make of the timing of the statement?— the statement? it ties into easter. at easter, the statement? it ties into easter. at easter. you _ the statement? it ties into easter. at easter, you usually _ the statement? it ties into easter. at easter, you usually see - the statement? it ties into easter. at easter, you usually see them i at easter, you usually see them going to church. it is usually a bit of a photo opportunity for the royal family. things might be a bit different this year. the prince of wales has been carrying on with all of his duties by balancing what we now know is an extremely difficult and sad situation at home, which the princess has said has really helped, the fact he has been by her side and brought great comfort. he has also

had to balance that. now we know this information, it would make more sense as to why he pulled out his godfather�*s memorial service not that long ago. there were questions about that. everything now evidently makes sense. the prince of wales will carry on with his duties were also balancing being a father and also balancing being a father and also being a husband, whilst also dealing with the fact his own father is also dealing with a cancer diagnosis as well. lots of pressure on his shoulders at the moment. he will be carrying on with work and standing upfor will be carrying on with work and standing up for courses which he believes should be spoken about that as his personal life. that believes should be spoken about that as his personal life.— as his personal life. that was pandora forsyth _ speaking to me earlier. just to show you the latest pictures coming out of russia. people have been queueing up of russia. people have been queueing up outside the hospital, all queueing in order to donate blood to

help those who were injured. more than 100 killed. we understand 115 were killed, at least 115 killed and more than 100 injured. those numbers keep climbing over the hours. stay with us here on bbc news. hello there. we've been getting used to some very mild weather over the past week or more. temperatures were up to nearly 19 celsius a few days ago, but a different feel to the weather this weekend. it's windy, it's colder and we will see a mixture of sunshine and showers. probably a better prospect for more sunshine as we head into sunday. but the culprit, this area of low pressure to the north of the uk. lots of isobars on the charts hit the strong winds. and our air source coming down from the northwest, from iceland and greenland, that's why it's feeling cold. so a chilly, blustery afternoon for many — lots of showers rattling

through, particularly in the north and the west. they'll be wintry on the hills. could see some hail and thunder mixed into the showers across the midlands and southern england at times. winds gusting 30, maybe a0 miles an hour in excess of 50 miles an hour across the north of the uk. so gales here as well. so on the thermometer, temperatures will read around 7 to 10 celsius. but when you factor in that strong west, northwesterly wind, it's going to feel more like these temperatures suggest. so quite a chilly feel out there. as we head into this evening and overnight, it looks like the showers continue. it stays blustery for all areas. but towards the end of the night, a lot of the showers fade away through central and southern areas. so lengthy, clearer skies start to develop. because of the breeze, tt�*s not going to be too cold. i think temperatures are 2 to 6 celsius for many of us. so then, for sunday, the reason we're seeing a little bit of a change is that area of low pressure starts to pull away and this ridge of high pressure starts to build and you will notice, particularly through the afternoon, fewer isobars on the chart. so it's going to turn less windy, but a breezy start to the day.

northern and eastern areas in particular where we'll see most of the showers again, wintry on the hills. but into the afternoon, the winds start to turn lighter, see increasing amounts of sunshine before it starts to cloud up out west later on. so with lighter winds, more sunshine around and it will feel a little bit warmer, i think for many of us, we're looking at around 9 to 13 degrees now as we head into next —— now, as we head into next week and indeed the run up to easter, it looks like low pressure will be sticking close by bringing fairly strong winds. at times, outbreaks of rain could even see a spell of hill snow across scotland for a while as colder air looms the north of the uk. so a rather unsettled new week to come. and, like i mentioned, for the run up to easter, with temperatures only slowly picking up by the end of the week.

live from london. this is bbc news. russia says it's detained suspects after the shooting at a concert hall near moscow where115 people are now said to have been killed. the islamic state group says it carried out the attack — a claim that's been backed by the us, which says it warned about a threat. we've the latest on the princess of wales who's revealed in a video message she's in the early stages of cancer treatment. m essa g es of messages of support from around the world but also messages of thanks after that very personal message

from the princess yesterday. hello, and welcome to bbc news, i'm lukwesa burak. we begin in russia where is being reported that 11 people suspected of involvement in a brutal attack on one of moscow's biggest music halls have been arrested, including four assailants. this is according to russia's fsb securityservice. at least 115 people are believed to have been killed when gunmen targeted the building on friday evening. more than 120 others are believed to have been injured in the asssault on the crocus city hall on the outskirts of the city. a large fire broke out in the building — that caused most of the roof to collapse. as armed forces rushed to the scene — an islamic state group claimed it was behind the attack.

the united states believes this is credible and says it had warned russia about large gatherings
