the indian government says its focusing on the emergency rescue operation at the scene near the city of amritsar. scores of people have been injured. this report by richard lister contains flashing imagery. fireworks and a burning effigy at a hindu festival in amritsar. people had gathered on the railway tracks. the noise was so great, they didn't hear the train. it ploughed right through them, leaving carnage in its wake. grief—stricken friends and family sat with the bodies profoundly shocked at the lives taken in one terrible moment. many others were injured. it's still unclear exactly how many casualties there were. some people took bodies away before the authorities arrived. the police commissioner said the track was very close to the festival location and their priority was to get

the injured to hospital. india's prime minister narendra modi tweeted his condolences to those who had lost loved ones, describing the tragedy as "heart—wrenching". an inquiry is now under way, but the risks presented by india's rail network are well—known. and this is just the latest in a long history of accidents. richard lister, bbc news. ravinder singh robin from the bbc‘s punjabi service hasjust arrived at the scene of the accident and filed this report. the injured were hospitalized in various hospitals in the area and are getting treatment there. captain singh has already announced some help to the injured and to the kin of those who have died. let me show you the place where the accident happened.

actually, you can just see the place where the train was. there are three tracks. the one train was coming and hit the people who were watching the dusshera festival. the people, those who were there, those who are injured, people came to rescue them and now authorities are doing their best efforts to treat them. hundreds of central american migrants heading for the us have broken through border barriers on a bridge crossing between guatemala and mexico. these are the latest images. mexican police in riot gearfired tear gas forcing them to retreat into no—man‘s land in front of the mexican border gates. the caravan includes women, children and old people. the mexican authorities have said they will assess each case individually, and only those migrants with valid documents will be allowed to continue. they've also asked the united nations to help process

the refugee status requests. this map shows the border between mexico and guatemala where the incident is taking place. it also shows honduras — that's where the group started off, they say they're escaping poverty and violence there. us secretary of state mike pompeo is currently in mexico city. here he is speaking about the situation. look, president trump is pretty clear about the largest issue that we face today after having negotiated that deal. we are quickly reaching a point which appears to be a moment of crisis. record numbers of migrants, the foreign secratary and i spoke about the importance of stopping this flow before it reaches the us border. we are deeply aware that the way that mexico will handle this, the way that you will handle this, is your sovereign decision. mexico will make its decision, its leaders and its people will decide the best way to achieve what i believe are our shared objectives.

and i thank you for all the effort that you have put into this over the last few days, including your request for humanitarian assistance to the united nations to address this migrant caravan. let's take a look at some of the other stories making the news. the european court ofjustice has ordered poland to suspend a law that lowers the retirement age forjudges in its supreme court. the law, which sparked protests when it came into effect, meansjudges have to retire once they turn 65 unless they're exempted by the president. poland says the reforms make the courts more efficient. china has reported its slowest quarterly growth rate since the global financial crisis. the growth figure for the july to september quarter was 6.5%, according to the national bureau of statistics. the cooling economy is a problem for china, whose economic challenges include high debt levels and an intensifying trade war with the us. police in turkey have been searching a forest near istanbul

as part of their investigation into the disappearance of the saudi journalist jamal khashoggi. it's been alleged he was tortured and murdered in the saudi consulate in istanbul more than two weeks ago. saudi arabia denies any knowledge of what happened to him. but turkey's foreign minister says the investigation has produced evidence and the results will be shared with the rest of the world, as our dipolmatic correspondent james robbins reports. does this forest near istanbul hold appalling evidence of murder? turkish police have reportedly searched here for the remains of the saudi journalist jamal khashoggi, who walked into his country's consulate in istanbul over two weeks ago and then disappeared. suspicion has fallen on saudi arabia's crown prince. on tuesday, the 33—year—old told mike pompeo, america's secretary of state, he knew nothing of what had happened. but now, a former head of mi6 has dismissed that denial.

sirjohn sawers believes the prince had thought the trump administration wouldn't complain about the murder. this appalling killing points to the evidence of it being ordered and carried out by people close to the crown prince of saudi arabia. i don't think he would have done this if he hadn't thought he had licence from the us administration to behave as he wished to do so. look at these pictures of the crown prince, and particularly this man, seen regularly in the background. the saudi security official is close to the prince and cctv footage leaked by turkey also places him outside the consul‘s residence in istanbul the day jamal khashoggi disappeared. and what about a leaked audio recording, allegedly released from inside the saudi consulate?

the sounds apparently of jamal khashoggi's terrifying last minutes. turkey has denied sharing it with other governments, but does not deny the recording exists. this spring, the saudi crown prince was greeted as a reformer by theresa may. britain is a close ally, but today, it is much trickier. if the stories we are reading turn out to be true, will that have an affect on our relationship? yes, it will, because if the stories are true, and it is still an if, they will be totally against our values as a country. investigations into jamal khashoggi's fate continue, but pressure for answers, however horrible, is building. james robbins, bbc news. while international diplomatic pressure grows on riyadh, attention is also focusing

on the fifteen men who travelled to istanbul the day jamal khashoggi disappeared. an investigation by bbc arabic can exclusively reveal that of those men, maher abdulaziz mutreb, had been trained in high level surveillance techniques which allowed saudi intelligence to monitor and track personal devices anywhere in the world. from istanbul, hanan razek reports. travelling the world were saudi arabia's most powerful prints, this man is reportedly a colonel in the saudi intelligence service. he is seen here in a visit to the us alongside the crown prince. now he is at the heart of the saudi journalist's disappearance. footage obtained by turkish media shows him entering the saudi consulate in istanbuljust hours before the khasoggi.

bbc arabic can confirm that he was trained by a hacking team, a group that specialises in teaching cyber spying techniques. this promotional video sells some of their expertise. exactly why we do. hacking teams can now affect devices and allow them to be tracked and monitored remotely from wherever they are in the world. a system that is actually being used by some governments to track and monitor their opponents. we have spoken to a european cyber expert who confirmed that he trained this man for two weeks in a military compound in riyadh in 2011. we have had to disguise his identity because of safety concerns. from the pictures, i recognised one person i remembered meeting before. i don't know exactly what his role was, but he wasn't operative was, but he was an operative for the saudi intelligence services. we knew him as "darkface" because he always looked grumpy, like he was on the sad side. he was introduced to the european trainer as an intelligent security operative. they have an easy time to control

people that are in the country because they control every gateway. they control everything on the internet, so that is relatively speaking easier for them, but controlling somebody on the outside is harder. so most likely, they put surveillance on these people. whetherjamaal was killed are not, his disappearance is still puzzling the world. what we are learning about those who are at the conflict that day poses a question about who was really behind it. stay with us on bbc world news, still to come... we have all the sports news and report on a trip to mercury, the planet closest to the sun. ada stewart mum of his victims have

a train ploughs into crowds watching a religious festival in northern india. at least 60 people have been killed. hundreds of us—bound migrants have broken through border barriers on a bridge crossing between guatemala and mexico. mexican police fired tear gas forcing them to retreat into no—man‘s land. the islamist preacher anjem choudary has been been released from prison on licence. he has served half of a five—year sentence handed down to him in 2016, for inviting support for the islamic state group. the bbc understands there will be restrictions on his movements and he'll be closely monitored by the security services. our home affairs correspondent june kelly reports. within hours of coming out of prison, anjem choudary was back

in a familiar place — in front of the cameras. he can be seen, but not heard, he is banned from speaking to the media. this probation hostel in north london is where he is initially being housed. it was before dawn when he was driven across the capital from belmarsh top security prison. during his time inside, he hasn't changed his views, according to counterextremism specialists. he's become hardened in his own extremism and in his own radicalised opinions. there have been numerous attempts to try and deradicalise anjem choudary, as part of the pastoral care service with imams in prison services. they have got nowhere. the whole world one day, my brothers, will be under the sharia, including hackney, moscow, new york, all of the countries under the thumb of the muslims. for two decades, anjem choudary was clear about the world he wanted to see. a master manipulator, he was at the centre of a network of violent extremists. michael adebolajo was one of the pair who carried out the savage street killing of fusilier lee rigby. another choudary disciple,

siddhartha dhar, is suspected of being part of an is killing squad. the former head of counterterrorism at scotland yard believes choudary‘s influence outstripped his character. i think we've got to be careful not to overstate him. he is a pathetic groomer of others and should be seen as such. i think we all have to be very careful about not overinflating his status and giving him some sort of mythical evil genius—type character, because that's not what he is. anjem choudary will be subject to a long list of conditions and supervising him will cost a lot of public money. as part of the restrictions, he will have to wear a tag and be under a curfew. he is banned from preaching and organising meetings. he can only see people who are approved and he is banned from meeting anyone with a terror connection. he will have to get permission to go on the internet. i don't think he should have been released, it sets a bad precedent

for what he's done and the damage he has done, to get two and a half years, not enough. i've worked with a lot of families, and one of the families i've worked with — it's ruined their lives. as the law stands, he was eligible for release now. the restrictions on him will last only a couple of years. 0n the eve of afghanistan's elections, kandahar has been forced to delay its poll for a week, after the assassination of the powerful local police chief. general abdul raziq, along with two other officials, was shot dead by his bodyguard after meeting us commander general scott miller inside the governor's compound to discuss election security. his funeral took place in kandahar earlier on friday. the taliban, who say they killed general raziq, referred to him as a "brutal police chief". but the american general paid tribute, saying he had "lost a great friend" and afghanistan had lost a patriot. 0ur chief international correspondent lyse doucet is in the afghan capital kabul.

she says the nation is realistic about the security situation, but people are determined to have their say. no one is expecting a perfect election in afghanistan, it is not possible at a time where afghans say they have never seen the situation so bad as it has been now. that is something to say in a country which has been through four decades of war, so election officials admit there will be violence, there will be fraud at the polls, but will this election be regarded as legitimate enough to allow the afghanistan political process to move forward? presidential elections are meant to be held next year. so they have got more than 50,000 police, army intelligence officials spread out across this country to secure the polling stations. they have a new biometric device, it has to be said a controversial addition to the process. it was brought in so late there are fears that it will not work. that there should be

training to use it properly. but it has been brought in to try to minimise fraud that has been going on at the polls. and always, what will be the turnout be? the taliban made it clear time and again that they will attack the polling stations, that they will try to attack the security forces. they have told afghans not to go out and vote, and yet, i have been here for every election that has taken place since the fall of the taliban. the threats are always there, but afghans are defiant. this is an act of bravery and they have shown election after election that they are willing to risk their lives to take part in this process. so many afghans this week have told us this, we're not scared of the taliban. we're not going to be intimidated. we want to cast our ballots to show that this process matters. so there is a lot at stake in these elections. and certainly the world will be watching and afghans will be watching to tell us what it says about afghanistan now. will perry has all the sport. we will start with football. but

jose mourinho takes his own side too bad with chelsea in the premier league. there was bad blood with antonio conte after united lost 4—0 there. mourinho describe the celebration as humiliating. he did not bring it up today but he said he would not blow up if united are successful at stamford bridge. when i celebrate like crazy my team goal at sta mford i celebrate like crazy my team goal at stamford bridge or my team victory at stamford bridge? i do not think so. i think i would try always to control myself, to respect the stadium and to respect the supporters, my supporters and my stadium for many years. it is a match that i want to do well for my players, for my team, for my supporters. that is what i want. i wa nt supporters. that is what i want. i want percent, manchester united tomorrow. the jazz ahead to it eden hazard does not need to go to spain

to win the battle on the world. it is not part of the appeal would increase his chances of winning euro's biggest individual honours. but his manager believes he can do that by staying in london. he can win everything, also the ballon d'or, without playing in spain. because for example, if the chelsea will be able to win the champions league and the belgian national team will be able to win the europa cup, he will be able to win everything. tie—breaks will be played at 12—all in the final set at wimbledon from next year.

it comes after the deciding set of kevin anderson's semifinal withjohn isner this year lasted almost three hours. that's prompted bosses at the all england club to act. so next year, if the final set is deadlocked at 12 games all, the winner will be the first player or team to reach seven points with an advantage of two or more points. the decision has predictably brought a big response on social media including from three—time wimbledon champion boris becker... former british number one greg rusedski. .. and former tour pro mardy fish says... and lewis hamilton was quickest in first practise for this weekend's us grand prix in austin, texas. hamilton finished 1.3 seconds ahead of his mercedes team—mate valteri bottas. ferrari's sebastian vettel down in fifth. hamilton will become world champion again if he wins sunday's race and vettel is lower than second. second practise has just got underway. christian wade has left rugby

first has ended in a draw for dubai last week. that is all this board for now. europe and japan will launch a joint mission to explore mercury, the planet closest to the sun, this weekend. a rocket will carry two probes that will detach after a seven—year—long flight to the least—explored rocky planet in our solar system. meghan bhartels, who's a science journalist, told me what they hope to achieve. the mission has a lot of science to do. it is looking at pretty much every aspect of mercury from its very innermost core out to sort of thin sheath of molecules that surrounds it. so a really wimpy version of the atmosphere that we live in here on earth. so lots be done. ok, so why do we need to know this? what does it tell us about the universe? sure. the problem of mercury is that it sort of messes up a lot of the explanations scientists have for how the solar system formed. so the hope is that by going to mercury and gathering a whole new set of data and asking all these

big questions, they can end up sort of tweaking the explanation for the birth of the solar system that we have now in a way that actually makes it make sense with all eight planets, not just seven of them. so it could really tell us quite a lot essentially about how all the planets came to be? exactly. the hope is that because we use our solar system as a stand—in for all systems around us, the hope is these models and explanations and ideas will also teach us more about other worlds, exoplanets and the suns that they orbit. so how challenging is this going to be? it is seven years to get there, incredibly hot there, they are not sending any people up there i am pretty certain, so tell us what some of the challenges are. it is definitely a challenging place to visit. as you mentioned, the heat is a big problem, but the cold

is also a big problem. there are really steep temperature changes when you deal with mercury because it turns very slowly. so the side that is near the sun is really hot and the side that is away from the sun is really cold. as you mentioned, it is also a long trip to get there. it takes seven years. the problem is you have to go really fast to get in towards the centre of the solar system but then you have to slow down a lot so that you do not accidentally hit the sun instead, which would be kind of a bummer. so that is why they have this really long orbit time to get there. there is a whole guide to this mission on our website. also worth following our science correspondent to. and i am on twitter. thank you for watching. good evening. frost and fog in the

forecast for the weekend but at least that means some fairly quiet and settled weather by date. this was taken on a friday morning in east yorkshire and the frog will be fairly dense once again but, the accident, most of it should clear and we will see some beautiful sunny skies. the reason for this weather is this ridge of high pressure. there are weak weather fronts surrounding the high—pressure introducing more cloud and also more moisture would speed the fog as well. there is quite a scarcity of cloud out over the ocean so having that week where the front drifted through friday and it will tend to drift away over the rest of the night. to the south, most certainly cold with some dense fog forming. the next weather front links back to the north west of scotland later in the north west of scotland later in the not so picks up temperatures of it here but chilly for the eastern lands in particular. and some fog

underneath that system as it is fairly unreliable cloud. there could be some dense fog around saturday morning which makes it more after this if you are travelling, especially on the faster routes. visibility down to around 100 metres 01’ so. visibility down to around 100 metres or so. but it will take time this time of year to clear away because the sun does not have the strength so the sun does not have the strength so he could linger to the late morning hours. it should clear and england and wales should be fine and dry but patchy rain coming to northwest england, northern ireland and western and northern scotland later. east of the pennines and eastern areas of the best of any brightness and warm at 16 or 17, especially with sunshine and a light wind. they are maintained through saturday night into sunday. the front for the north is to pep up a bit more. still problems with frost and fog across many southern areas under a week like regime and clear skies. a bit more rain pushing south and fizzling out across england and wales with at least sunshine returns to scotland and northern ireland bar and a few showers but quite a

certificate drop in temperature with fresher air. sunshine and the south lifting the fog of it more quickly and the 17 or 18 degrees. then the wea k and the 17 or 18 degrees. then the weak front moves away on monday and weak front moves away on monday and we get a much stronger ridge of high pressure moving in for much of the first part of the week. but behind it to the north, it will allow a somewhat colder northwesterly airstream and it will be colder still on the end of the week. this is bbc world is. the headlines... they train has ploughed into a crowd at a religious festival in india killing more than 60 people. there has been a gathering on train tracks to burn an effigy. 0n the border mexico and guatemala, the mets cling the —— american police have tried to block migrants crossing. investigators are looking for the missing saudi journalist jamal khashoggi have widened their search to istanbul. meanwhile, the consulate in istanbul are testifying
