welcome to bbc news, broadcasting to viewers in north america and around the globe. i'm mike embley. our top stories: more weapons are found at the home of the man who carried out america's worst mass shooting of modern times. 59 people were killed, hundreds more injured. the gunman has been named as stephen paddock, who fired on crowds of people from the window of his hotel room before killing himself. a minute's silence is held at the white house as president trump urges the country to stand together. last night, a gunman opened fire on a large crowd. it was an act of pure evil. the leader of catalonia says he's not planing a traumatic split with spain despite the disputed independence referendum. also in the programme, the mysteries of the body clock, revealed by three scientists awarded the nobel prize. police investigating the mass

shooting in las vegas say they have found more weapons at the home of the man thought to have carried out the attack. at least 59 people were killed and more than five hundred were injured when the gunman opened fire on crowds at a music concert from a room in a nearby hotel. the shooting happened during an open—air music festival attended by thousands of people. shortly after 10pm local time, dozens of rounds. were fired from the mandalay bay hotel as the gunman took aim from the window of his room on the 32nd floor, where he was later found dead by police. he's been named as stephen paddock — a retired accountant — who lived in the state of nevada. police say they have no idea

about his possible motives. james cook reports from las vegas. in the cold nevada desert, country music is warming the throng. the time is 10:08pm. gunfire. the noise prompts confusion. the crowd, 22,000—strong, hesitates. it takes a moment, a deadly moment, before they realise they are under attack. gunfire. by now, a second round of bullets is raining down. there is a pause. the gunman is reloading again. he is high above them, in the mandalay bay hotel. panic follows. it is a scramble to live. there were people hiding underneath my car for cover. and there was a gentleman that was shot, and he said, "can you help me?" and so i put him in my car, and i had like six people in my car, people without shoes, running, just to get away, and... we just hit the ground, and just lay there and hung

onto each other. and it was quiet for a bit, and then fired another 30 rounds, and then quiet. and then what we were doing was, every time he had stopped, he was reloading, we had gotten up and started making our way towards the fence. and then he'd started shooting again, and we'd hit the ground. gunfire. by now, the music fans are frantic. if they can, they run, and like this woman, they hide. we were sitting ducks, and you could hear the bullets coming closer. and then he would — and then it would get quiet, and then he would, like, reload, and then he would start going again. and the girl that was standing right behind me, about two feet, she got shot in the stomach. and everybody thought at first it was just firecrackers. and then everybody — and then itjust kept going more. we felt the shots,

and then we ran... ..to the hangar, to the airport, and we just kept running. it was... once we got out the back, we started seeing the people that were shot, and the people that were dead. and it — that's when it hit me, that this was real. within half an hour, officers know the gunman is in the hotel. explosives ready, they prepare to go in. this police radio recording captures the moment they storm the room. breach, breach, breach. explosion. by now, it is nearly midnight, and the gunman is dead, apparently having killed himself.

he left the city in chaos, with hospitals overwhelmed, and too few ambulances for more than 500 casualties. we just need to get people over to the hospital, ok? ok, go ahead. put them all in the back. alright. hundreds of people remain in hospital, where surgeons have been battling to save life after life. we had all hands on deck. we had eight or nine trauma surgeons alone in the facility. we had eight operating rooms rolling simultaneously, operating on patients, doing what in trauma we refer to as damage control. so it was a matter of getting them on the table, stopping the process of them dying, stabilising them. as for the gunman, he was stephen paddock, a 64—year—old retired accountant from mesquite, an hour's drive from the vegas strip. he had checked into the hotel on thursday. as far as his history and background, we haven't completed that part of the investigation yet. but we located numerous firearms within the room that he occupied. for a western democracy,

the united states has seen an astonishing amount of horror like this. but, even here, this is carnage on a different scale. james cook, bbc news, las vegas. stephen paddock lived in the city of mesquite, 80 miles from las vegas. he checked into the mandalay hotel last thursday. our correspondent laura bicker reports on what else is known about the gunman. stephen paddock, a retired accountant and high—stakes gambler, turned a country music concert into a killing field. he had been in his room on the 32nd floor of the mandalay hotel for days, waiting with a cache of rifles and automatic weapons. his familyjust can't comprehend the horror of his crime. my brother did this, i... this is like it was done — you know, like he shot us. imean...

if he'd have killed my kids, i couldn't be more dumbfounded. i mean, it doesn't — there's nothing. so last communication... there's nothing. i can show you the text, he said, "how's mum?" where the hell did he get automatic weapons? he's not — he has no military background, or anything like that. i mean, when you find out about him — like i said, he's a guy who lived in a house in mesquite, and drove down and gambled in las vegas. he did stuff — ate burritos. imean... the 64—year—old made few friends in his suburban retirement village in the quiet town of mesquite. police found more guns and ammunition when they raided his home. what's unique for us is that the gunman, the shooter, and the person with him, we in the mesquite police department have not had any contacts with these people in the past. we haven't had any traffic stops,

we haven't had any law enforcement contacts, no arrests or nothing. he would disappear for days to nearby las vegas to gamble, but also made money from rental properties, and came across as odd to some of his tenants. he roamed around the apartments, talked to you, always real casual. and they showed his picture. i was shocked, because like i said, he was a nice guy. strange, but nice. the question is, what would lead a man with no criminal history, no known strong political views, and no apparent motive, to commit such relentless carnage? laura bicker, bbc news, mesquite. dr pete blair is from texas state university and he has co—authored an fbi study into deaths in mass shootings. he's in new braunfels, texas. good to talk to you. clearly this investigation is at a very early stage. what is known so far? well,

it is always difficult at an early stage to make too much of the information that is coming out. often, more information emerges later which changes the picture. we see somebody who was able to acquire a large number of weapons, either acquire those automatic weapons or change them, modify them, into automatic weapons. he picked a location to attack, a large concert venue, where he could injure a lot of people very rapidly. sometimes with mass killings, i know that whatever the actual motive turns out to be, the whole process of planning, the surveillance, modifying the weapons, feeling like you are in a movie sequence, seems to be part of the attraction? yes, we absolutely see with these people that there is the planning process that there is the planning process that goes on before the attack happens. often they have some sort of grievance, whether that is a legitimate grievance or not, they are angry about something, and they start to fixate on that. they are unable to relieve that angered the

way the rest of us would. they begin to enter a downward spiral with a start to think about an attack, they start to think about an attack, they start to think about an attack, they start to plan the attack out, they acquire weapons, they do surveillance on the targets, they go and look at sightlines, they inspect things to make sure the attack would work the way they wanted it to. does the fact the killer was in such an elevated position mean they were more deaths? is it harderfor somebody like this to kill people in this way if you are closer to them? well, in this particular case, where he was above and some distance away from the concert venue, able to see into a large portion of the venue, from what it sounds like, it essentially created an open field for him to shoot at people from. it also creates confusion for them in trying to figure out where the gunfire is coming from, and that definitely could have been a factor in increasing the rate of casualties. doctor black, there is clearly more to come on this. for the moment, thank you very much indeed. —— dr blair. the leader of catalonia,

carles puigdemont, has said he is not planning a "traumatic" split with spain, after a disputed independence referendum on sunday. he said he wanted a new understanding with the central government in madrid after hundreds of people were injured in violence at polling stations. our europe correspondent damian grammaticas reports. galvanised by what they see as the violence of the spanish state, hundreds took to the streets of barcelona today, hands raised in silent protest at the brutal tactics used by police trying to prevent sunday's independence vote. we have no weapons. our weapons are... this is our weapon. words are our weapon. catalonia has a history of resisting the spanish state. it is little more than a0 years since spain was a dictatorship, a memory evoked again today. the dangerfor spain is both sides becoming ever more polarised. the government, with its crackdown, looks increasingly remote and heavy—handed. but the catalan side, with its tactics, may leave the government with little choice than to believe it had to take

action, to prevent what it sees as an illegal bid for independence. the independence leader, carles puigdemont, today called for european mediation and the withdrawal of riot police. but spain's prime minister, mariano rajoy, isn't backing down. his government is threatening to revoke catalonia's autonomy if it tries to declare independence. this was the police response yesterday. spain's constitution forbids secession, and the poll had been banned by the courts. so there could be more to come. but, if anything, it may be hardening the resolve of the two million who voted for independence yesterday. do you think there is a way catalonia and spain can resolve this now, peacefully, to everybody‘s satisfaction? i don't really think so. i mean, peacefully? no.

catalonia, home to more than seven million, is one of spain's richest regions, with a distinct language and outlook. but it has long felt ignored. and pro—independence leaders tell people they will be better off without spain. so the cracks in spanish unity are widening. firefighters applauded today. they tried to protect voters from the police. a general strike is planned tomorrow. many looking on don't believe it will come to a split. we found these friends enjoying a beer. serafin said he believes only a third of people support independence. sunday's vote was inconclusive. and jose doesn't believe the promises that a split would make people richer. but, at the heart of spain's political crisis, centrifugal forces that are hard to resist —

the lure for catalans of taking greater control of their destiny. stay with us if you can. still succumb, the debates that never ends. this latest mass shooting has again shone a light on gun control in america, but there is very little expectation that change. —— for change. in all russia's turmoil, it has never come to this. president yeltsin said the day would decide the nation's destiny. the nightmare that so many people have feared for so long is playing out its final act here. russians are killing russians in front of a grandstand audience. it was his humility which produced affection from catholics throughout the world. but his departure is a tragedy for the catholic church. israel's right—winger ariel sharon visited the religious compound and that started the trouble. he wants israel alone to have sovereignty over the holy sites, an idea that's unthinkable to palestinians. after 45 years of division, germany is one.

in berlin, a million germans celebrate the rebirth of europe's biggest and richest nation. this is bbc news. our main headline: police investigating sunday's mass shooting in las vegas — america's worst in modern times — say they have found more weapons at the home of the man they said carried out the attack. while the focus in the mainland us is on las vegas right now, the american territory of puerto rico is still struggling from the devastating effects of hurricane maria. this weekend saw president trump castigate the mayor of sanjuan for her poor leadership, after she called for the white house to speed up the response to the crisis. president trump flies to puerto rico later today. aleem maqbool reports from ponce, on the island's south coast. you see that big tree? yes, the

bathroom. luciano points out the rooms of his home because there would otherwise be little way of telling what was here before hurricane maria tomic shreds. this is where you work? my goodness. they told me to get down. what is incredible is luciano and his wife we re incredible is luciano and his wife were in the house at the time it was destroyed, trapped in their living room for several hours before they could escape, miraculously armand. when the water came in... -- unharmed. they have lost everything and while they have heard us relief workers are on the island, no help has come their way yet.|j workers are on the island, no help has come their way yet. i think they started to come in about three days ago. but we have never seen an

american people to call to help. because everything got stuck in some one area. in the airport. i don't know what's going on. but on the other side of town the americans have just arrived. on a mission to one particular building. the reason the us military and emergency workers have come here is because it is an old peoples home around two hours outside the capital. this is the first time people have seen any help at all and they have been living without power and water since the hurricane. struggling up the stairs we found one woman who said she felt isolated since the hurricane, especially since communications are still down. hurricane, especially since communications are still downm hurricane, especially since communications are still down. it is just terrible. nothing, nothing, nothing to eat. no water, no light, nothing to eat. no water, no light,

no elevator, and i live on the third floor. her neighbour orlando is one of the few that has been visited by american relief workers in this town but he was scathing about the us response on this us territory. you think of a us state instead of a possession would have been treated differently. no one has been here in the last ten days. isn't that proof enough? after visiting the old people's home the americans left town. here it is neighbours and the church doing most of the work. providing clothes and food where people have none. glory to god, says the pastor of this church, reciting a prayer. thank god we are here to help, he says. because for many, no one else has come to help. they are just waiting for life to get better.

the attack in las vegas is the latest in a long list of mass shootings in america, with the debate over guns once again a divisive issue. our north america editorjon sopel has been looking at the response to what happened in the city. in vegas last night — terror, fear and mayhem. in the nation's capital this afternoon, 2500 miles away — a brooding, reflective silence. bell tolls. there is shock as well as anguish, even though this country has been here so many times before. he brutally murdered more than 50 people and wounded hundreds more. it was an act of pure evil. in moments of tragedy and horror, america comes together as one — and it always has. until now, the worst shootings were the nightclub attack

in orlando, where omar mateen killed 49 people in an act inspired by so—called islamic state. and before that was the killings at virginia tech university, when 32 people were killed. but in terms of shock, surely nothing eclipses sandy hook in connecticut, when 20 children, aged between five and seven, and five teachers were killed at their elementary school — an act of brutality so shocking that it moved the then president to tears. they had their entire lives ahead of them. birthdays, graduations, weddings. kids of their own. today, lawmakers from connecticut sought to reopen the age—old debate on gun control, senator chris murphy saying, "it is positively infuriating that my colleagues in congress are so afraid of the gun industry." "it's time for congress to get

off its ass and do something." but gun control is unlikely to go anywhere. the industry in america is huge, and its lobbying organisation has managed to see off any attempt at reform. indeed, one of the ironies of previous mass shootings is that sales of weapons tend to increase as gun owners fear that new controls might be introduced. but that is unlikely to happen with president trump, who has allied himself closely to the national rifle association. as your president, i will never, ever infringe on the right —— as your president, i will never, ever infringe on the right of the people to keep and bear arms. never, ever. cheering. it's estimated there are as many private guns in circulation as there are people — around 300 million. around 30,000 people die each year in gun related incidents. that figure includes suicides, accidents and murders, which means, in the last year, four times as many people in the us died from guns than the total number of coalition forces killed in afghanistan and iraq during 16 years of war. in his address to the nation, donald trump said the american

people would be seeking explanations, but the one issue he didn't touch upon was whether gun control could have played a part. the nra believes that the way you stop a bad man with a gun is to have a good man with a gun. but how that would have helped in the circumstances of las vegas last night is anyone's guess. let's take a look at some of the other stories making the news: one of the fiercest critics of the russian president, vladimir putin, has been sentenced to another twenty days in jail. alexei navalny was convicted of violating a ban on organising public meetings. police arrested him in moscow on his way to address a rally. the main palestinian factions, fatah and hamas, have taken a step

towards resolving a decade—old dispute with a rare visit to gaza by the palestinian prime minister. rami hamdallah said it was time to end division among palestinians. three american scientists who discovered the secret of the body clock have won the nobel prize for physiology or medicine. the body clock, or circadian rhythm, is the reason the human body wants to sleep at night, but it also drives huge changes in behaviour and body function, as our medical correspondent fergus walsh reports. each of us has an internal body clock that synchronises with the sun and the day—night cycle. but how these circadian rhythms were controlled was largely a mystery, until the work ofjeffrey hall, michael rosbash and michael young. the latter was at rockefeller university in new york this morning. hearing they had won the nobel prize, he said, was quite a shock. i really had trouble even getting my shoes on this morning.

i would go and pick up the shoes, and then realise i needed socks, and then realise i need to put my pants on first! laughter. just as the earth rotates every 2a hours, so our circadian rhythms work in the same cycle. in 1984, the three scientists isolated a gene in fruit flies that controls the body clock. the gene codes for a protein that accumulates in cells during the night and then degrades during the day. since their discovery, sleep science has gone from fringe to mainstream. the body clock is critical to our health. in the evening, it triggers the release of the hormone melatonin, which helps make us sleepy. in the morning, the stress hormone cortisol rises and keeps us alert. our body clock helps regulate our appetite, blood pressure and body temperature. your body clock is central to much of our biology.

fine tuning much of what we do to the varying demands of the rest—activity cycle. we also know that disruption of the body clock, as in long—term shift work, for example, is associated with higher rates of cancer, a greater susceptibility to diabetes two, greater chance of obesity. the nobel committee said the findings of the three scientists had vast implications for our health and well—being. a good night's sleep is increasingly being viewed as the best medicine. las vegas police said they found guns and and munitions at the house of the man who shot dead 59 people and injured 500 and i9 guns were found also in his car and hotel room. and you can get in touch with me and most of the team on twitter, thank you for watching.

hello. further strong winds at times this week, even the risk of gales as we maintain a very autumnal flavour to our weather. this low pressure system was the wind—maker on monday. it's still producing some strong winds in the far north of scotland and northern isles as tuesday begins. elsewhere, high pressure's building in, winds easing a bit pressure building in. with high pressure, most places are going to be dry starting the day with plenty of sunshine. here's a look at things, eight o'clock in the morning. a few showers dotted about northern and western scotland, driven along quickly on this quite strong wind. far north of scotland, more epseically into the western isles, there could be some gusts early on of about 50—60 mph. one or two showers in the north—west of england, but very few and far between. for most of us, it'll be a dry start to the day. a good deal of sunshine. a breezy start, though, with temperatures a bit lower than this outside of the large towns and city centres. some of us in single

figures as the day begins, but there is that sunshine to compensate. some good sunny spells continuing through the day. just some patchy cloud developing. still a few showers running into western parts of scotland, but most places dry. it's a fresh—feeling breeze, mind you. out of some sunshine, in that breeze, there will be a chill around. temperatures for the most part in the mid—to—low teens. but, actually, not too far away from average for the time of year. tuesday evening, tuesday night, we'll see showers in western scotland merging to give some longer spells of rain in places. winds starting to pick up once again towards the far north of scotland into orkney, a very windy start to wednesday morning. south of this area of rain, we'll see a lot of clear weather going into wednesday morning. quite chilly again under clear skies. some spots into mid, perhaps even low—single figures in the countryside. wednesday brings a band of rain across scotland eventually into parts of northern ireland, mainly north—west england as we go through the day. south of that, we'll hold onto some sunny spells. still be quite breezy, won't be much warmer. and as we go into wednesday night, rain gathering for northern ireland, parts of northern england and wales, as this area of low pressure moving

across the uk. parts of scotland seeing it, parts of the far north staying dry, but we are concerned about some of the rain and the impact. it could be quite heavy on wednesday night into thursday morning. coastal gales. and then as the system clears away from southern parts on thursday, it stays quite windy. a cool wind. some gales with showers across eastern parts of the uk. or it could be quite windy for a time on friday. but by friday, there's another area of high pressure building across the uk. the winds easing, and most places will end the week fine and dry. this is bbc news. the headlines: police investigating sunday's mass shooting in las vegas, america's worst in modern times, say they have found more weapons at the home of the man they said carried out the attack. a local sheriff told journalists they seized 18 guns, explosives and thousands of rounds of ammunition. the gunman was named as 64—year—old wealthy retired accountant stephen paddock. it's claimed he used an automatic weapon to fire on crowds from a las vegas hotel, killing 59 people

and injuring more than five hundred more. as police stormed his hotel room, he killed himself. president trump has appealed for unity and peace among americans in response to what he called the "pure evil" of the shootings in las vegas. mr trump said the nation was joined together in sadness, shock and grief. he later led a minute's silence in memory of the victims at the white house. we just need to bring you
