hello and welcome to bbc news. turkey says it will reveal all the details about the killing of journalist jamal khashoggi, after saudi arabia admitted for the first time he had been killed in its consulate in istanbul. our diplomatic affairs correspondent james robbins reports. after 2.5 weeks of denial, saudi arabia is changing its story. state tv announced the admission that jamal khashoggi was killed by its officials. translation: the discussions that took place between him and the individuals that met with him during his presence in the saudi consulate in istanbul led to an argument and fist fight with jamal khashoggi, which led to his death. that is also the admission of a big saudi lie — previous insistence that the journalist didn't just walk into the consulate, he left safely too. many believe the killing could only

have happened with the permission of saudi crown prince mohammad bin salman, and that the new story of a fight, rather than premeditated murder, is designed to shield him. president trump, who has been torn between criticising the saudis and protecting business with them, now appears willing to accept the new saudi explanation as credible. they've arrested, just for the people at the table, a large number of people having to do with the event that took place in turkey in the consulate, the saudi consulate, and... it's a big first step. it's only a first step but it's a big first step. do you consider it credible, their explanation for it? i do, i do. but many disagree, including within his own republican party. senator lindsey graham said... so will the saudi admissions and arrests solve britain's dilemma — how to respond?

hardly. the government is committed to uphold a world order based on rules, but it doesn't want to inflict too much damage on saudi partnerships it values enormously. the foreign office confined initial reaction to a short statement. it begins... but don't expect action before turkey publishes some of its evidence. turkish officials have suggested a grotesque sequence of torture and killing inside the saudi consulate. turkey is promising to reveal all its findings. james robbins, bbc news. donald trump says the us is planning to withdraw from a nuclear agreement with russia. the treaty required both countries to get rid of short and intermediate—range missiles, but washington has accused the kremlin of breaching the deal. here is chris buckler. the intermediate—range nuclear

forces treaty was seen as a landmark accord when it was agreed by the us and russia 30 years ago. but the us has insisted that russia has abandoned the treaty by deploying banned cruise missiles. president trump now says that he is no longer prepared to let the kremlin violate an agreement that america has honoured. we're not going to let them violate the nuclear agreement and go out and do weapons, and we're not allowed to. we are the ones that have stayed in the agreement, and we have honoured the agreement. but russia has not, unfortunately, honoured the agreement. so we're going to terminate the agreement, we're going to pull out. his national security adviser, john bolton, is holding meetings in moscow at the start of the week, and he is expected to tell russian leaders that the us

is withdrawing from the treaty. hundreds of central american migrants have used rafts and boats to cross the river marking the border between guatemala and mexico. thousands of people were left stranded on the frontier bridge after police stopped them entering the us on friday. huge crowds have marched in london to demand a referendum on the terms of britain's withdrawal from the european union. 0rganisers from the group called people's vote said 700,000 people took part. pro—leave groups dismissed the protest, saying people had already expressed their will in the brexit referendum. more now from our political correspondent chris mason. they came from every corner of the uk and beyond. it is a campaign that wants what it calls a people's vote — in other words, another referendum. what do we want? all: people's vote! when do we want it? all: now! there were some political faces you mightjust recognise here, but the vast majority

were ordinary people still deeply angry about brexit. it's all been lies from the start, and it needs a second vote. we need a second vote to get us out of this mess! to what extent can today persuade people who voted a different way from you to vote a different way in future, if there was another vote? i'm not sure that today will. it's seeing the politicians making a complete mess of the negotiations that will persuade them. in the first vote, we thought the brexiteers knew what they were doing. you know, now we know they couldn't organise a party in a party shop. i feel really strongly that, you know, people particularly where i'm from in the north didn't vote to lose jobs, didn't vote to close factories. and i think that, you know, it's right to make it clear to people that that is the consequence of what they voted for. more than anything, i was born in 1982, i feel more european than i do british, in some ways.

so, at a personal level, i feel like my identity is being lost. a noisy walk in the autumn sunshine ended, for those at the front, at least, in parliament square, where some celebrities... hello, london! ..and politicians from a range of parties addressed the crowd. let the message ring out loudly and clearly today. it's time for this vital issue to be taken out of the hands of politicians in westminster. there is no doubting this is a big march, there is no doubting the passion of those taking part, but their demand for another referendum collides with the government's opposition to one. they hope, though, with politics as turbulent as it is at the moment, anything is possible. good morning, everybody. the march in london wasn't the only brexit—related event today, though. here in harrogate, in north yorkshire, a much smaller gathering, but one of a series from leave campaigners. that's our message — get on with it. fulfil your promises to us. you said, if we voted to leave, it would happen.

it needs to. and some ukip supporters decided to take their pro—brexit argument to the anti—brexit march in london. they were not well received. just shows how thick you are — you don't know... it was a reminder, not that it is needed, that the divisions, anger and open hostilities provoked by the referendum have not gone away. chris mason, bbc news, at westminster. it has now been confirmed at least 59 people died after being run down by a speeding train during a hindu festival on friday. it is india's worst rail disaster this year. eliza philippidis reports. this man will not be coming home to his wife again. he was just one of the thousands celebrating the festival marking the triumph of good over evil.

families and friends were out watching a burning effigy of the demon king, rahman, as part of the festivities on friday when the train ploughed straight through them. watching the fireworks from the train tracks, he, like so many others, did not hear the fast approaching train. grieving relatives have been scouring the bloodied fields for anything their loved ones left behind. but anger is growing at the authorities over why the festival was allowed to be held so close to the train tracks. translation: when they have to get votes, they come and beg from home to home. they did not come to say that our children had died. we should getjustice. local hospitals were overwhelmed with the number of people needing treatment. they quickly ran out

of space for the dead, and were forced to leave some bodies outside. police now say bodies were so badly dismembered that it will take days to identify many of the victims. india's railway board has denied responsibility for the accident and the killing of those rundown by the train. so far, the punjab chief minister has declined to comment on the likely reason behind the accident, but says he is committed to finding out what happened. we are announcing a magisterial inquiry, under our commissioner, who will hold a magisterial inquiry and give us a report within four weeks. the disaster near amritsar, in the north of the country, has led to new demands for safety reforms to india's accident—plagued railway system, which records thousands of deaths each year.

the governments say they are keeping fares low for the 23 million passengers who use the network daily. but, after decades of underinvestment, critics say this has left public safety at risk. several million afghans have voted in parliamentary elections, the first to be organised entirely by the government since 2001. polling stations which could not open on saturday plan to do so on sunday. but the elections have been marred by violence, as sekunder kermani reports from kabul. the taliban told them to stay at home. instead, afghans began queueing outside polling stations even before they had opened, with thousands of soldiers deployed across the country. 15 people were killed in a suicide bombing in kabul, and there were dozens of other smaller incidents.

but, throughout the day, voting did go ahead. translation: of course everyone is scared, because security is bad. but, despite all those fears, we are here and voting anyway, because our destiny depends on it. translation: i hope the people who are elected will do something for the young generation, and to improve security for the country. inside polling stations, women and men voted in separate sections. almost 9 million people have registered to vote for more than 2,500 candidates. despite the threat of violence, people here in kabul are turning out to vote, determined to have a say in how the country is run. but, across afghanistan, nearly a third of all polling stations are closed because of security concerns. in a country where politicians are often seen as corrupt and linked to ethnic tensions, there is a degree of optimism about some of the new candidates standing, many of whom are young and from professional backgrounds.

the election process is the will of the people, the people want to express their will by going to the polling stations, so that's why the taliban are afraid. previous elections in afghanistan have been marred by allegations of fraud. many fear that will happen again, despite new biometric devices meant to prevent anyone voting more than once. today's election is a key test of afghanistan's security forces, ahead of next year's more politically significant presidential elections. it has been a day of defiance, but also, as it often is in afghanistan, of bloodshed. sekunder kermani, bbc news, kabul. this is bbc news. the latest headlines: there has been international condemnation after saudi arabia admits the missing journalist jamal khashoggi was killed in its consulate in istanbul. let's stay with that story now.

earlier, i spoke to karen attiah, global 0pinions editor at the washington post. she was a friend ofjamal khashoggi. i asked her what he was like. jamal was a kind, very gentle — very sort of determined man, though. he was extremely passionate about his writing. i mean, in his first piece for the post, shortly after we were able to find him and recruit him to write for us, he said that the situation in saudi arabia pained him. he told me that in our first e—mail exchange, and that it pained him to have to write about what was happening in the kingdom under crown prince mohammad bin salman. at the same time, you know, in our discussions, conversations, what shone through was that he really cared. he really cared about saudi arabia and wanted to use his work to — yes, to highlight the injustices,

to highlight people who had been rounded up and put into prisons unfairly, without due process or discussion or debate. but he supported a number of mohammad bin salman‘s social reforms — the ability for women to drive, finally. he is — he wanted some sort of economic reforms to come for saudi arabia's population, many of whom live in absolute poverty. so for me, in the year that we worked together, he was just very, you know, energetic about having the opportunity to finally be free to write what he wanted to write, after being kicked out of so many media houses and newspapers and being silenced for so long. so that's why, you know, the fact that he has finally been silenced in this horrific way is — is so utterly painful. and the tragedy is that he was

embarking on a new chapter in his life in istanbul, with an engagement, as well. yes, absolutely. i think the first thing he told me when we met was that the pressures on him, his decision to speak out and to be a thorn in the side of the saudi authorities cost him his previous marriages. and so, in the last months, he did seem relaxed. he seemed like he was settling in a little bit to his new life, and lifestyle, i suppose. he was travelling back and forth between istanbul, london and the us, moving to washington. so he seemed happy. he seemed happy and energetic, not somebody who seemed like he was under some sort of imminent physical threat. karen, just turning to the investigation, how confident are you we are going to get the truth, given what is obviously going on behind the scenes between washington

and turkey and riyadh? first of all, i am confident in our resolve to push aggressively for all answers and accountability, on all sides. we have done that from day one. obviously, you know, saudi arabia for its part has lied to the world for 17 days, and has produced no evidence of any of their claims, whether it was jamal walking out of the consulate after 20 minutes, to now this new attempted cover—up, frankly, that he died in a fist fight. you know, the explanations are almost absurd. and we are all obviously anxiously waiting to see what turkey will do, and how turkey will respond. but i think we are urging and hopeful that the us government will pursue this to the fullest of their abilities,

whether that is making sure that intelligence reports onjamal in this case will be available to those who have congressional oversight over these matters, to possible sanctions, to suspension or cancellation of arms deals. so that's something we are aggressively pursuing and pushing for. more now on the hundreds of central american migrants who've used rafts and boats to cross the river marking the border between guatemala and mexico, in an attempt to continue theirjourney to the united states. thousands of people were left stranded on the frontier bridge after mexican police stopped them entering the country on friday. aleem maqbool reports. it is a bridge that for the white house is now an immigration battlefield. straddling guatemala and mexico, it is currently home to thousands of migrants who have trekked from honduras, all wanting to get to the us. though they still have to get through mexico, which is not letting them in, president trump has described this convoy as an assault on the us, an onslaught of criminals. we plead to donald trump, this woman tells me. may god soften his heart so we can enter the us.

children are sleeping on the floor, and we don't know how long we'll be here. it's not fair. it has been a heartbreaking time for some. we met linder, who got split up from his 13—year—old son five days ago, and hasn't seen him since. translation: i'm upset, and i don't know what to do. should i continue, and hope he arrives, or should i turn back? i need him so much. they have all been risking the dangers, desperate for a better life in the states. well, small numbers of people have been allowed across the border, but for the most part the mexican gate has remained shut, and with living conditions here on the bridge getting more difficult, we are seeing many trying other means of trying to get the mexico. after a week of threats from washington, central american governments have come to an agreement to transport people

back to their home country for free if they sign up. reluctantly, nearly 600 have already put their names forward. translation: we're sad because we thought we'd make it to the us. when you come from poverty, you try to be optimistic, but it's been difficult. we are returning to suffering. for some americans, the sight of migrants giving up is a welcome one. for others, it is an embarrassment that their country, built on the idea of taking in those seeking prosperity, now delights in turning them away. but some migrants just won't take no for an answer. we saw some of the hundreds who had decided to cross into mexico by boat, determined and desperate enough to continue theirjourney to the usa by any means. kidnappers in tanzania have released one of africa's richest people.

the billionaire mohammed dewji was in captivity for more than a week. it's unclear if a ransom was paid. rhodri davies has more. these are the remnants of a personal and national ordeal. in an upmarket area of dar es salaam, police were searching the scene where africa's youngest billionaire was released. mohammed dewji was set free early morning after ten days of captivity. he was unharmed apart from some bruises on his hands and legs. mohammed dewji broke the news himself on his company's twitter account, saying: "i thank allah that i have returned home safely. "i thank all my fellow tanzanians and everyone around "the world for their prayers." and while the kidnappers remain at large, they received a warning. translation: our country is safe and will continue to be safe. these people will be punished

according to the law. we must bring an end to this. we can't let the kidnappers get away with this or they'll simply try again. dead or alive, we'll be happy either way. these people are our enemies. and in a country with high levels of street crime and poverty, the kidnapping of someone with so many friends stands out. dewji's family were able to offer a $4a0,000 reward for information leading to his rescue. that's after armed gunmen abducted him at one of the city's hotels as he arrived for a morning work—out. known locally as ‘mo', dewji is said to be worth $1.5 billion and his companies employ more than 22,000 tanzanians. so, his release has settled an ease for many in the country, even if it's still unclear whether a ransom was paid and what it's still unknown where the kidnappers are. rhodri davies, bbc news. europe and japan have launched

a joint mission to mercury, the planet closest to the sun. the two spacecraft will take seven years to reach their destination. 0ur science correspondent jonathan amos has more. the beginning of a very long journey. bepicolombo is setting out on a 9 billion kilometre trek to the inner solar system. this is europe and japan's first mission to the planet mercury, and it'll be hugely challenging. where the joint probes are headed so close to the sun, it's as hot as a pizza oven. novel technologies must protect the spacecraft from the hellish conditions. scientists hope they'll make a raft of new discoveries. mercury is an oddball. it has an oversized iron core that no—one has yet explained, and surface materials that shouldn't be there in so hot an environment.

our current theories of solar system formation, including the earth and the other planets, can't explain mercury. it's an anomaly. so we need to go to mercury and find out more information about the planet so we can really understand how our solar system formed. british teams are heavily involved. they've built instrumentation and spacecraft components. the sun's immense gravity will pull hard on bepicolombo. this means the probes must be careful not to go too fast and overshoot mercury. an arrival date has been set for 2025. jonathan amos, bbc news. a giant mural that's not been seen for nearly a century has been uncovered in rome. bal tic tac, by the italian painter giacomo balla, was found on the ground floor of a building owned by the bank of italy. the bbc‘s tim allman has more. art can appear at in the most mundane of places. behind the walls of this fairly nondescript building,

something from the past, and the future. this mural, called bal tic tac, a riot of red and blue and yellow was created to adorn the entrance of a popularjazz cafe in the 1920s. when the cafe closed, the mural was covered up and the building went on to become a lighting shop and then a bank. translation: i wouldn't hesitate to define this as an archaeological discovery of something modern. we knew it had been here, we thought it was completely lost. 0n the contrary, it was still there, the freshness of the artist's work. that artist was giacomo balla. he was part of the futurist movement. his work embraced modernity and depicted light, movement and speed. translation: bal tic tac by giacomo balla was considered completely lost except for some pictures and sketches made

by the artist. the survival of the mural under decades of paint and wallpaper has been described as miraculous. it will now be restored and become part of a museum that should open at the end of 2021. and then people will be able to see this artistic miracle for themselves. some pictures to bring you from syd ney some pictures to bring you from sydney australia. the duke and duchess of sussex are spending the afternoon with the straight in prime minister, scott morrison. harry and his pregnant wife were meeting nevers of the community and school children. it is all part of their 16 day to. the weather now with alina jenkins. hello. for much of england and wales, saturday was a day of blue skies and sunshine.

barely a cloud in the sky here in north yorkshire on saturday afternoon. as ever, there were some differences. western parts of scotland saw some mist, hill fog, patchy light rain and drizzle, and here's yet another contrast. with the help of the fern effect and some sunshine, aberdeenshire and moray saw temperatures around 20 celsius. now, through sunday, we've got a cold front slipping its way south and eastwards, some persistent rain across northern and western scotland, northern ireland through the morning. as it moves into northern england, the midlands and wales, the rain tends to fizzle out. so we're just left with really a band of cloud and the odd spot of rain. some sunshine following on behind.a few showers for the far north of scotland, where it will be increasingly windy. ahead of our band of cloud, light winds, still some sunshine across southern and south—eastern england. and so here, we'll see temperatures up to 18 or 19 celsius, one last day of autumn warmth, and quite widely, 11; to 17 celsius on sunday. now, through sunday evening, here's our band of cloud continuing to weaken as itjourneys south and eastwards, we'll see some clearer

skies developing as we go into monday morning. more of a breeze, some drier air, so mist and fog shouldn't be too much of a problem first thing on monday morning. and we'll all notice a dip in the temperature, particularly across northern ireland, northern england and scotland where temperatures will be getting closer to freezing. so, as we start the new working week, we've got this area of high pressure building, but notice this squeeze in the isobars. that's going to continue to bring some very strong winds to northern and western scotland, gusts of 50 to 60 miles an hour through the early hours of monday morning. further outbreaks of rain. but away from here, further south across scotland into northern ireland, much of england and wales, we're going to start the new week with plenty of sunshine. a cooler feel, though. we've got a brisker northerly wind. so, compared to the highs of 19 or 20 celsius, it's going to be more like 12 to 11; celsius on monday afternoon. it's a similar sort of day on tuesday. we've still got this area of high pressure, it's a really dominant feature through much of next week. still some windy conditions to the far north of scotland and some outbreaks of rain, and it looks like some of that rain could just filter a little bit

further southwards down towards the central belt, maybe towards the borders on thursday. more cloud around for northern ireland and the far north of england. but elsewhere, further south across england and wales, once again, there'll be a good deal of sunshine, but a brisker north or north—westerly wind with temperatures again just 12 to 11; celsius. so, to sum up the week ahead, away from the far north of scotland, it's looking mainly dry, there'll be some sunshine, but it is likely to turn colder by next weekend. bye— bye. this is bbc news, the headlines. turkey has promised to reveal every detail about the killing of the journalist jamal khashoggi who died inside the saudi consulate in istanbul. there's been international condemnation after riyadh said mr khashoggi died as a result of a fist—fight. donald trump says the us is planning to withdraw
