hello and welcome to bbc news. there's been a major purge in the government in saudi arabia. ten royal princes, among them several senior ministers, as well as dozens of former ministers, have been detained in a campaign to stamp out corruption. crown prince mohammad bin salman, who's in charge of the new anti—corruption committee, appears to have sidelined powerful rivals. it seems the heads of the saudi national guard and navy have been replaced. we'll bring you more on that as we get it. we stay in saudi arabia because state media there says the military has shot down a missile over the capital, riyadh. officials believe the weapon was fired from yemen, where houthi rebels, backed by iran, are fighting the saudi—backed government. mohamed taha from bbc arabic says it's clear the houthis intended to cause major damage. it could not be denied because, as you said, whether the missile or parts of it hit the airport or a building in the airport,

whether it has been intercepted or not, but you know, at the end of the day, there is a fire, there is explosion in parts of the airport. the fact that these missile managed to get to riyadh is significant. i'm sure what happens tonight will have a very interesting effect on what happens in the war in that era. mohamad taha of bbc arabic. and in a further development in the region, iran has rejected accusations by the lebanese prime minister that it's spreading violence across the middle east. saad hariri resigned from his post unexpectedly, saying he feared for his life. iranian officials say his resignation is a saudi plot to create tension. martin patience reports from beirut. it is an honour to be here with you, mr president. for the prime minister of a small nation, saad al—hariri has had some

very powerful friends. that is because lebanon matters in the middle east. it is a country outsiders fight to control. and today, an extraordinary sign of that — the prime minister resigned, saying he feared assassination. speaking from saudi arabia, which backs him, saad al—hariri fired this warning to iran. translation: i want to say to iran and its followers that they are losing in their interference in the affairs of the arab world. our nation will rise up, as it has done in the past, and cut off the hands that wickedly extend into it. iran and saudi arabia are fighting a proxy war across the middle east. in lebanon, tehran backs hezbollah, which commands strong support. but its opponents say it operates as a state within a state. and its armed wing was accused of killing saad al—hariri's father,

rafik, more than a decade ago by a massive truck bomb. it traumatised the nation, but ultimately reshaped the middle east. now some are asking whether his son's resignation will do the same. this announcement has left people here stunned and created enormous uncertainty. lebanon has generally been spared the violence seen elsewhere but now many lebanese fear their country could be a casualty in the wider regional struggle. let's take a look at some of the other stories making the news. president trump has just landed injapan on the first leg of his asia tour, which is certain to be dominated by the crisis over north korea's nuclear programme.

later in the week, the president will travel to south korea and then china, the key stop on his five—nation visit. typhoon damrey has killed at least 19 people in central and southern parts of vietnam. rescue teams say more than 33,000 people have been moved from their homes and at least a dozen are missing. stay with us here on bbc news. still to come: turning back time — we'll tell you about the cycling enthusiasts who are harking back to an earlier age. as we've been saying, president trump has arrived injapan on a five—nation asian tour set to be dominated by the crisis over north korea. here's a report from sophia tran—thomson. touchdown in tokyo, today, old enemies are now allies. after flying in on air force one from hawaii,

president and first lady met with us troops stationed in the region. ivanka trump with prime minister are they have her father ‘s arrival. at present‘s strong stance on pyongyang's nuclear weapons programme will be welcomed by the japanese leader. and when donald trump arrives in south korea on tuesday, people also have strong support in seoul. but people commitment across the region to squeeze the north even tighter through sanctions. and that means getting china on board. 0n wednesday, donald trump meets resident xijinping, their talks may be less than cordial if mr trump pressures his counterpart to take a stronger line with pyongyang and raises the issue of what he calls china's unfair trade practices. this marathon i2 china's unfair trade practices. this marathon 12 day tour will end with regional summits in vietnam and the philippines. leaders there will be listening to hear how committed this

america first president is to the rest of the region at a time when china continues to emerge as the dominant regional force. well for more on the president's tour of asia, stephen mcdonnell —— labour has called on all the main political parties to agree a new, independent system to tackle sexual harassment at westminster. it comes ahead of a meeting planned by theresa may with opposition leaders on monday to discuss proposals for fresh grievance procedures for staff and mps. the crisis has now spread to holyrood with the scottish nationalist msp mark mcdonald resigning as a government minister over "inappropriate" behaviour. 0ur political correspondent iain watson reports. this is the week when politicians‘ private lives became very public. past actions by some mps have had serious consequences. there have been accusations, resignations, investigations, and it's clear the current crisis at westminster will continue to fill the front pages. tonight, there are newspaper claims that sir michael fallon lost his job when a journalist contacted downing street to say he'd behaved

inappropriately towards her 14 years ago. friends of michael fallon don't deny that this took place but i understand no single incident led to his departure. and tonight, a new resignation, this time, the childcare minister in the scottish government. in a statement the snp's mark mcdonald said: and he went on to apologize to anyone he may have upset. political parties are now responding to the spate of allegations. the conservatives have toughened their code of conduct. the shadow foreign secretary has said a younger generation no longer put up with harassment and many women mps have been pressing for an independent body to hear any complaints and labour's leadership has now agreed. we need to make sure that our youngsters know

that we will listen to them, that we will help, that it is not acceptable, and that they do not need to put up with any of it. you know, we've got to say no to this and they will find friends and allies, people like me, who will not put up with this. you know, some of the things i've heard in the last week have been so disgusting. the physical structures of parliament are being made fit for the 21st century, and, on monday, theresa may wants to do much the same thing with the wider culture here at westminster. she is holding cross—party talks to try to get broad agreement on tackling harassment and inappropriate behaviour, but some mps are worried that political careers could end on the basis of rumour and the settling of old scores. there is a febrile atmosphere and there's a feeding frenzy that some have described, i think probably rightly, as a witch—hunt. yes, this may sell tomorrow's chip wrappings, but this is more serious than that. and i believe that my colleague, members of parliament have a right —— and i believe that my colleagues, members of parliament have a right

to the same naturaljustice as everybody else and they are not getting it. party leaders want to be seen to be taken tough action against harrassment but they know, perhaps even fear, that they are not entirely in control of events. iain watson, bbc news. a 7—year—old girl has died after suffering critical injuries in an incident at a house in south—west london on friday. 55—year—old robert peters, whom officers say was known to the victim, has appeared in court charged with attempted murder. he's been remanded in custody until december. lawyers for the us soldier bowe bergdahl, who pleaded guilty to abandoning his post in afghanistan, say they'll appeal the sentence he was given by a militaryjudge on friday. bergdahl was spared a custodial term but given a dishonourable discharge, a $10,000 fine, and a demotion to the rank of private. his lawyers had argued that he was suffering from mental conditions and shouldn't face prison. i spoke a little earlier to eugene fidell.

—— militants of the islamic state group are reported to have detonated a car bomb at a gathering of people displaced by fighting in the syrian province of deir az—zour. syrian state media said dozens of people gathered on the eastern bank of the euphrates river had been killed or injured. on friday, is lost control of deir az—zour city, its last remaining stronghold in syria. the ousted head of the catalan government, carles puigdemont, has urged all democrats to unite ahead of snap elections in catalonia. a spanishjudge has issued european arrest warrants for mr puigdemont and four of his allies. they went to belgium after the catalan parliament declared independence, and madrid reacted by imposing direct rule. commenting on social media, mr puigdemont called for the release of political prisoners. eight former members of the regional government are being held in custody in spain. so what chance is there that belgium

will send mr puigdemont back to spain? nick vamos is a former head of extradition at the uk crown prosecution service and now partner at peters and peters law firm. there has to be a judicial process now in belgium to decide whether the warrant is valid and should be executed and, therefore, mr puigdemont should be returned to spain. that is far from straightforward. there are several tests that the court will need to apply before it reaches a conclusion. the first one is whether what he did in spain would amount to an offence in belgium. that is the dual criminality test. he is charged with, among other things, rebellion and sedition. it is not at all clear whether that would be an offence in belgium. they have their own federal system there and separatist movements there as well. you can see immediately how that is sensitive

for a belgian court to consider. 0ne one of the japan now. president donald trump has arrived at the airbase and is addressing us troops stationed there. drove back the invaders during the korean war. tremendous courage. tremendous bravery. from here they enforce the precious peace during the long and bitter cold war. and the aftermath of the devastating 2011 tsunami, this bass served as the launching point for operation, duchy. —— tomadachi. the largest relief effort in american history which said the lives of thousands of thousands of great japanese citizens. like those

who came before you, you always rise to the occasion and you never, ever let your country down. general martinez, general pas,, general pasquerette, brigadierwinkler, all moss, and chief master sergeant green, you leave the forces under your command with exceptional skills and devotion and america is tremendously grateful to you. (cheering and applause). we are also very fortunate to stand alongside such strong and capable allies... apologies, i think we just

had a slight problem with the line coming from the airbase. we hope that donald trump paying tribute to us troops stationed there for thanking him for all of the work they have done and we just heard towards the end there will welcome that he was getting troops and i think we have the loan back. let's have another listen, if we can. thank you very much. 0n on behalf of the american people i wa nt on behalf of the american people i want each and everyone of you, both american and japanese, to know that your service and commitment helps keep us all safe. america is profoundly grateful for all you do and we are back home starting to do, i will tell you, and you're reading, and you're seeing, really, really well. the stock market is at an all—time high...

well. the stock market is at an all-time high... applause unemployment back in the united states is at a 17 year low. almost 2 millionjobs have been added since a very, very special day, it's called election day, november the eighth, 2 millionjobs. it's a lot ofjobs. and we have dealt isis one brutal defeat after another, and it's about time! cheering it's truly inspiring to see american airmen and marines and... studio: there we are, president trump at your, yokota airbase

talking about the stock market and low unemployment. —— yokota airbase. let's go to steve mcdonald, our correspondent, in tokyo. we have just seen donald trump speaking at the airbase, what else is on the schedule? people here in tokyo are waiting to see what this visit will bring in terms ofjapan and us relations but also crucially in terms of a policy around dealing with north korean nuclear weapons. we saw donald trump after this arrival meeting at that face. he's going to do the same thing in south korea when he gets there. that is sending some sort of a message in terms of this country's military preparing this should it come to that with north korea —— preparing must. practically, though, he is playing golf with shinzo abe. both the us and japanese governments

believe that's a good chance for them to discuss things in an informal setting. but no matter what it does, weather it be that or if he's having some steak dinners and the like, north korea will be looming large at all of these events —— whether it be. looming large at all of these events -- whether it be. how do the two countries differ in their approaches towards north korea, if they do differ? steve, a re you differ? steve, are you able to hear me? i'm sorry, i think we have got another fa u lty sorry, i think we have got another faulty line, this one to tokyo u nfortu nately faulty line, this one to tokyo unfortunately but we will try to go back to stephen macdonald when we can. you can keep up with the story on our website, head to: that will provide you all you need to know in what will be the longest tour of asia by a us president in 25 yea rs. around the world, people release helium balloons or sky lanterns to mark special occasions.

but campaigners here in the uk say the objects are a growing threat to animals, which can die from becoming entangled in them or swallowing them. dan johnson reports. the litter in our seas, an issue largely hidden. and how it gets there isn't always clear. so look at this and think about it. where do they land ? what goes up must come down. and the result is trouble at sea. it's wildlife getting tangled in them, the plastic litter is very unsightly, and... campaigns have been running for years but the message isn't getting through. most people think, "oh, we're having a great time, we will let balloons off, there isn't much of a problem." but it is when you bring that visual impact that has been ingested and getting wrapped up with bits of string and bits of balloon out of their mouths as well. and it could be internal, we find that out when we're able to do a post—mortem on that. the amount of plastic in the ocean is already a threat to marine

ecosystems and sea life. and the truth is, it's impossible to tell how much balloons are adding to that problem, because the impact is out there, offshore, unseen and unmeasured. so balloons get released without consideration of the consequences. it's landed in the field, and, being curious, she swallowed it. and they can be just as deadly on land. jennifer's horse died after choking and panicking. right through here with it tangled up, in her back leg, crashed into this, broke her neck, and then she laid dying horrendously for what seemed an eternity. the horse was aiming to be a top showjumper just like her sister here. they don't understand that they are releasing litter into the air, airborne litter, and if anybody dropped the call is for a wider ban on balloons and people to keep their impact in mind before

they drift off out of sight. danjohnson, dan johnson, bbc news, danjohnson, bbc news, on the south coast. police are ramping up security for sunday's new york city marathon in the wake of the deadly terror attack that took place on tuesday. this year's race, expected to draw millions across the five boroughs, is expected to have the tightest security ever. austin halewood reports. the marathon will go on because new york goes on. the words of the city governor, andrew cuomo, in the wake of the terrorist attack that left eight people dead in lower manhattan. the new york city marathon is the largest of its kind in the world and just five days on from the atrocity, despite a shaken public, organisers believe it is important the race goes ahead. new yorkers are resilient. i think they love to make statements and this is a way to make a statement.

to come together and show the world that we don't hide. a bigger police presence than ever before is expected as more than 50,000 runners from 125 countries take place in the race, starting on staten island and then weaving through the city's five boroughs before ending in central park. with safety as the top priority, organisers and runners are confident the city has taken the necessary precautions to protect everyone. certainly the start and finish areas are very secure areas. if you don't have the appropriate identification, a bib for a runner, credentials if you're working, you will not get in. when you get through, you'll be checked like you always are. since the 2013 boston marathon bombings in which three people were killed and over 260 injured, security at new york's marathon has already increased. runners are no longer allowed to run in baggy costumes that could conceal weapons.

large backpacks and other bags are prohibited. in 2013, i was actually part of the terrorist attack in boston. the one thing i do know, and that boston showed, is the resiliency and how running can be quite cathartic. i know new yorkers are as tough as they come and this makes us grow closer in a sense. this is an event notjust for the runners but for the people of new york, because despite the horrors they've faced this week, 2.5 million people are still expected to line the streets to watch the race. austin halewood, bbc news. and one more sporting note, because they were turning back time in the czech republic on saturday, namely to the victorian era. cycling enthusiasts gathered in prague for an annual racing event, but the bikes they were using were a little old fashioned, as tim allman reports. meet the members of

the czech velocipedist club, claimed to be the oldest sporting club in europe. every year, the men and women, although mostly men, come to this park in prague to remember simpler times. the slower pace of life, riding their penny farthings. there is a spot of racing, albeit at a fairly sedate pace, but there is also some formation display cycling. the velocipedists may hark back to the 19th century, but this event is a bit more recent than that. translation: it started as a race. the tradition was born in 1993 when prague hosted the world championship of historic bicycles. we had some broken arms

and concussions so we decided it was better to go more slowly and enjoy the ride in the autumn. and enjoy it they did. and no doubt come the same time next year they will return. the gentlemen and even the odd lady of the czech velocipedists club doing what velocipedists do. tim allman, bbc news. that's the way it's looking this hour. if you want to get in touch on twitter. let's have a look at the weather. after the rain cleared through on saturday afternoon, colder, brighter conditions moved in place but plenty of showers rattled in from the north—west. through the course of the night, a showery one across western areas. thunder and hail and further east it has been dry with clear spells. we start sunday morning on a chilly note.

generally speaking it will be drier day than saturday for most. plenty of sunshine but noticeably cold in all areas. we start sunday off with some of the showers across western areas with wintryness over the hills. they will slowly fizzle away into the afternoon and become more confined to western and south—western and eastern coastal areas. many inland places dry but cold. eight, 10 degrees. those values struggling. as we head towards bonfire night though, temperatures will be falling. you can see that blue hue there across scotland. a few showers for the northern coast, a few through the north channel. there will be some showers across the east coast. for most places it will be dry for bonfire night. but cold and you will need to wrap up warm. a few showers around the channel islands as well. as we head further on into sunday

night it turns even colder. you can see these blue colours across the north, extending south to central and eastern areas. some places potentially seeing lows down to —5, —6 degrees. it could be a misty and cold start for monday with some frost around. the ridge of high pressure which brings the fine weather on sunday and monday morning ebbs away and allows this to push it off the atlantic, bringing in thickening cloud, strengthening wind and outbreaks of rain start on monday but dry with plenty of sunshine. the sunshine diminishes from the west as the weather front moves in that will stay bright across east anglia and the south—east. spots of rain developing across the west of britain and persistent heavy rains in northern and western parts of scotland. it will be milder but cold. for tuesday, a messy picture. the weather front will continue eastwards and heavy persistent rain as it travels eastwards. mild but turning cold again across the north and west

with sunshine and showers. on into wednesday, we are between weather systems. at clear from the south—east in the cold clear conditions in its wake with more wind and rain pushing into the north and west later on. this is bbc news. the headlines: there's been a major purge in the government in saudi arabia. ten royal princes, among them several senior ministers, as well as dozens of former ministers, have been detained in a campaign to stamp out corruption. the crown prince appears to have sidelined powerful rivals. president trump has landed injapan on the first leg of his asia tour which is certain to be dominated by the crisis over north korea's nuclear programme. later in the week the president will travel to south korea, and then china. labour has called on all the main political parties to agree a new, independent system to tackle sexual harassment at westminster. it comes ahead of a meeting planned by theresa may with opposition leaders on monday to discuss proposals for fresh grievance procedures for staff and mps. now on bbc news, a look at the news

through the eyes of foreign journalists based in the uk. it's dateline london. hello, i'm shaun ley and this is dateline london. they do say politics is showbiz for ugly people. this week, british politics was found to have something in common with hollywood — sexual sleaze. in washington, it was financial sleaze under the spotlight. the special prosecutor investigating whether donald trump's presidential campaign was influenced by the russians laid his first
