this is bbc world news today. i'm martin stanford. our top stories. there's been international condemnation after saudi arabia admits the missing journalist jamal khashoggi was killed in its consulate. hundrends of thousands of protesters march through london, demanding a referendum on the government's final brexit deal. thousands of people travelling across central america to the us are now stranded on mexico's southern border. and two satellites developed in europe and japan leave earth for a 7—yearjourney to the planet mercury. hello and welcome to world news today. france has become the latest country to condemn the killing of jamal khashoggi, saying a thorough investigation is needed. after previously denying involvement in the disappearance of the saudi journalist,

the authorities in riyadh said he had died in a fist fight at the country's consulate in istanbul. president trump has tried to play down the crisis, calling the admission a "good first step". our diplomatic affairs correspondent james robbins reports. after two and a half 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 a fist fight with jamal khashoggi, which led to his death. that's 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 mohammed 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 have 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, that explanation? 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. 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. joining me now from istanbul is borzou daragahi, he's an international correspondent for the independent. so many questions still left unanswered. there are many questions that are unanswered. and this point the saudis have made their case. it

seems some elements in the trump administration have accented it, others are sceptical. what counts is how the turkish government will react. they have the evidence, they are continuing their investigation and have made no announcement yet. all indications are that the turkish government finds the saudi exploration insufficient and they are going to come out with more details about the investigation in the coming days. what are the remick occasions for saudi arabia in the near term? the germans already talking about curtailing arms sales by instance —— what are the ramifications. beyond those business deals, many of those will remain. it suggests a weakening of the crown prince, mohammed bin salman. he's been badly damaged by this. whether he hangs on as crown prince is a good question. it looks like he'll

remain in his office but there is a serious attempt notjust on the part of dissidents and activists and so on to weaken him, but also on the pa rt on to weaken him, but also on the part of very powerful members of the royalfamily part of very powerful members of the royal family who feel sidelined by him. in addition he has a very powerful adversary in the turkish president, erdogan, who opposes mohammed bin salman butt wants to retain good relations with saudi arabia. he will not push this for a sidelining of mohammed bonzart on. the tragedy for khashoggi is that he thought that turkey was a safe place, and he was thinking about setting up a new life there with his fiancee. indeed, reports are that he had purchased an apartment in istanbul. istanbul is a safe haven

for arab politics and culture. many who had to leave their country because of uprisings are in this city and he thought this would be a good place to stay in gauge in middle east politics —— to stay engaged in middle east politics while keeping his residence in washington for his column with the washington for his column with the washington post. which begs the question, what is next for president erdogan? what is his next move? they'll continue the investigation, continue possibly leaking information about the investigation. one serious question everyone has, the tapes, these tapes that supposedly exist that record the final moments of the mall khashoggi. will turkey released the tapes and what effect will they have if released? that's what effect will they have if released ? that's one what effect will they have if released? that's one thing, if they

exist... the saudis. thank you for joining us. organisers say 700,000 people have taken part in a demonstration in central london calling for a public vote on the government's final brexit deal. it's thought to be the largest protest of it's kind to date — but prime minister theresa may has already ruled out a fresh vote. the bbc‘s political correspondent chris mason reports. they came from every corner of the uk and beyond. it's a campaign that wants what it calls "a people's vote". in other words, another referendum. there were some political faces you mightjust recognise here. but the vast majority were ordinary people, still deeply angry about brexit. it has 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 am not sure that today will, it is seeing the politicians making a complete mess of the negotiations that will persuade them. on the first vote we thought the brexiteers knew what they were doing. now we know they couldn't organise a party in a party shop. i feel really strongly that people where i am from in the north did not vote to lose jobs or close factories and i think that it is 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 on 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 politicians from a range of parties and some celebrities addressed the crowd. there's no doubting this is a big march and there's 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, that 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. in harrogate in north yorkshire, a much smaller gathering, but one of a series from leave campaigners. that is 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... booing it 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. let's take a look at some of the other stories making the news.

australia's governing coalition has lost its one—seat parliamentary majority after a by—election in sydney. independent candidate, kerryn phelps, comfortably won the wentworth seat, which has historically been held by the centre—right liberals. the previous mp was the former prime minister malcolm turnbull, who was ousted by his colleagues in august. the defeat suggests the liberal party will face major challenges in next may's national election. a us lotteryjackpot has reached the record sum of $1.6 billion after months without a winner. the prize, known as mega millions, has been growing sincejuly. the next chance of drawing the six lucky numbers will be on tuesday. the duke and duchess of sussex have opened the fourth invictus games tournament in sydney as part of their tour of australia and new zealand. prince harry used a speech at the event to talk of his joy at his wife's pregnancy. the games were started by the prince in 2014 and will see injured service personnel from 18 countries compete

in 11 sports over 8 days. thousands of migrants are stranded on the border between guatemala and mexico, after mexican police blocked their efforts to enter en route to the us. the migrants, who are mostly from honduras, say they are fleeing violence and poverty, and include women and children. earlier i spoke to the bbc‘s ana gabriela rojas who's at the border. she said the mood there is one of sadness and desperation. some people say fainted, some woman and some children because it's really hot today, really hot for the last 20 hours, since people have been waiting and they are really tired. they walked for over six days. the caravan started in honduras. so they are really tired, they've been walking with just

whatever food they'd been given by the people in guatemala. what about supplies? do they have any food or water? not really. the mexican government has sent some relief but mainly water, so far. they let in the people that have fainted, they let them in for some medical help. and the police have used tear gas to try and quell any attempts to breakdown their lines. is there any threat of that again, do you think? not at the moment, really. it was yesterday when they reached the border and they tried to pass through. so when some tear gas was fired. but at the moment, no. at the moment they let in some of the first people, about a0 people today, half an hour before. so, now people are a little bit down, expecting the government

will let them in and let them ask for refugee status in mexico. staying with that story, there are reports that dozens of women and children from the honduran migrant caravan are being allowed into mexico. that's according to a report on the afp news agency, quoting the mexican ambassaor to guatemala. some going over the river, using ropes to pull themselves across. stay with us on bbc world news, still to come: millions of afghans brave attacks and threats to vote in the first parliamentary elections since 2001 to be run exclusively by the afghan government. a historic moment that many of the victims have

waited forfor decades. the former dictator in the dock. older, slimmer. but as he sat down, obedient enough. dawn, and as the sun breaks through the piercing chill of night, it lights up a biblicalfamine, now in the 20th century. the depressing conclusion, in argentina today it is actually cheaper to paper your walls with money. we had different policies in the past. but as good friends we have always found a good and lasting solution. concorde bows out in style after almost three decades in service, an aircraft that has enthralled its many admirers for so long, taxiing home one last time. this is bbc world news today.

i'm martin stanford. the latest headlines. there's been international condemnation after saudi arabia admitted that the critical saudi journalist jamal khashoggi was killed inside its consulate in istanbul. hundreds of thousands of protesters march through london, demanding a referendum on the government's final brexit deal. afghanistan has been holding long delayed parliamentary elections today amidst tight security. it's the first set of elections since international forces ended their combat mission in the country four years ago. but the build up has been marred by violence — with 10 candidates killed over the past few months — and voting delayed in one province following the assassination of the local police chief earlier this week. secunder kermani reports from kabul.

the taliban told them to stay at home. instead, afghans began queueing outside polling stations even before they'd opened, with thousands of soldiers deployed across the country. 15 people were killed in a suicide bombing in kabul. there were dozens of other small incidents. but through 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. i hope that 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, from more than 2500 candidates. despite the threat of violence, people are turning out to vote, determined to have a say in how

the country is run. but across afghanistan, nearly one 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's a degree of optimism about some of the candidates handing, many of whom are young and from professional backgrounds. the election process is the will of the people and 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's been a day of defiance, but also, as it often

is in afghanistan, of bloodshed. holly hamilton has all the sport. a busy day in the premier league. let's start with drama at chelsea, as ross barkley scored a stoppage time equalizer to snatch a 2—2 draw with manchester united, but there was fracas on the touchline after that goal, with a member of the chelsea backroom staff running into mourhinho's technical area at stamford bridge, which caused a scuffle. things had calmed a little at the full time whistle, mourihno says that chelsea boss maurizzio sarri has apologised to him for the behaviour of the member of his team. before all this, antonio rudiger had the hosts' 1—0 lead by the break, but then anthony martial scored twice to fire united ahead, until barkley scored that 96th minute equaliser. mourihno, keen to remind chelsea fans there of the three titles he won with them.

don't go always in my direction. he was very un—polite, but sarri took care of the situation. he apologised and after the game and his assistant apologised, which i accept his apologies. so for me, the story is over but don't do what everybody does, saying that it is mourinho that does things. ididn't i didn't see anything. i've spoken with jose i didn't see anything. i've spoken withjose and i didn't see anything. i've spoken with jose and understood i didn't see anything. i've spoken withjose and understood immediately that we were in the wrong side, in the wrong way of the situation. and so the wrong way of the situation. and so i've spoken with the member of my staff and i have dealt with this immediately. elsewhere in the premier league,

liverpool beat huddersfield 1—0, mo salah with the goal. man city are top with a 5—0 win over burnley, it was goalless on the south coast bewteen bournemouth and southampton. cardiff are out of the relegation zone after a 11—2 win at home to fulham, while the cottagers drop into the bottom three. newcastle are now bottom, after they were beaten by brighton at stjames' park and two goals inside a minute saw watford beat wolves 2—0. cristiano ronaldo has become the first player to score 400 goals in europe's top five leagues, asjuventus dropped points for the first time this season. ronaldo's fifth serie a goal forjuve adds to his 84 premier league goals for manchester united and 311 in la liga for real madrid. ronaldo's tally puts him 11 ahead of lionel messi, who's scored 389 la liga goals for barcelona. barcelona will face an anxious wait on the fitness of lionel messi after the striker injured his arm against sevilla.

they're due to play real madrid in el clasico next weekend. meanwhile real madrid were beaten for the fourth time in five games as they lost to levante at the bernabeau. the result put further pressure on coach julen lopetegui, whose side remain fifth in la liga, three points behind leaders alaves. home favourite daria kasatkina had to come from a set down to beat tunisia's ons jabeur in three tough sets to win the kremlin cup in moscow. last year's finalist was outclassed by jabeur in the first set, dropping her serve twice. but she regrouped in the second, taking it on a tiebreak to level the match. the final was jabeur‘s eigth match in as many days and she looked visibly tired on the court, as kasatkina lifted her second wta title in front of her home crowd.

finally, sebastian vettel led a ferrari one—two in final practice at the united states grand prix, with lewis hamilton just behind in third. hamilton will be crowned world champion for a fifth time in austin tomorrow if he outscores vettel by eight points. follow all the build up on the bbc sport website — bbc.com/sport. for the moment back to you. thank you. kidnappers have released one of africa's richest people. tanzanian 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.

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." 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 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 from one of the city's

hotels as he arrived for a morning work—out. known locally as mo, dewji is said to be worth $5 billion known locally as mo, dewji is said to be worth $1.5 billion and his companies employ more than 22,000 people in tanzania. so his release has settled unease for many in the country, even if it still unclear whether a ransom was paid and while it's still unknown where the kidnappers are. two spacecraft on a mission to mercury have been launched by europe and japan. it will take the probes seven years to reach the closest planet to the sun. our 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 is as hot as a pizza oven. novel technologies must protect the spacecraft from the hellish conditions. scientists hope they will 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 formations, including the earth and other planets, cannot explain mercury, it is 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 have built instrumentation and spacecraft components. the sun's immense gravity will pull hard on bepicolombo, meaning 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. we'll have to put that in our

calendars. thank you forjoining us. we'll have further updates of course for you through your day. from me, martin stanford, at bbc news centre, goodbye. for much of england and wales, blue skies and sunshine. certainly the case in lyme regis. temperatures up to 17 or 18 celsius, slightly higher across aberdeenshire. further west across aberdeenshire. further west across scotland, a different story, mist and fog, light rain and drizzle, rain becoming more persistent overnight over the northern and western isles. elsewhere in scotland, mainly dry but cloud increasing. the cloud extending into north—west england, into wales. further south—east, clear skies, the lowest temperatures
