will to hold a closed cemetery. we'll have more on this when we get it. we start here in the uk where the government has told airlines they must "fulfil their duties" to passengers who've had their flights cancelled or delayed due to monday's air traffic control problems. hundreds more flights have been cancelled on tuesday — and thousands of passengers remain stranded. the disruption is expected to continue for several more days. this report from our transport correspondent — katy austin. the august bank holiday descended into flight chaos, with hundreds cancelled yesterday and more today. we are still at rome airport trying to get home, we have been here since 11.30 yesterday morning. it's now been more than 2a hours. we boarded ourflight last night and then were told to get off the flight because the aircrew have been flying for too long. ourflight has been rescheduled for this afternoon but there are other flights that have been cancelled going into london so we just hope to get out today. in liverpool this morning, passengers were also getting bad news. we'd booked to take the kids to dublin for the day and we got here and were told it's cancelled. we are waiting in line to see if we can find something else. struggling to find a way to fill- in our day until 11 o'clock tonight, and just the extra cost. the disruption was caused by a technical issue at air traffic control nats, which gives details of planes and their routes which wasn't working so flight plans had to be processed manually and a number of flights had to be limited. the incident was of extremely high magnitude. even minutes can do damage to airline scheduling but hours, in the summertime peak when airlines are operating as many flights as they can using all of their planes and crews and flights are full, it's really the worst time for it to happen and causes the maximum disruption. by mid—afternoon yesterday, the issue had been fixed but the knock—on impact continues. airlines are grappling with aircraft and crews being out of position and some staff being over hours. some passengers face a long wait to get home. we stayed in paris for the night, as you can see. we then spoke to ba on the phone this morning after not receiving any e—mail confirmation about our flight cancellation. on the phone, they couldn't book us on to anything until thursday morning. nats is investigating what happened and will report back to the aviation regulator. the experts that look at these things have told me that it was not a cybersecurity incident but we will look at it in great detail to see what happened, what we can do to reduce the chances of it happening again and whether there are any further things that can be put in place to reduce this sort of issue. it is hoped that by tomorrow, schedules will be looking a lot more normal but the number of cancelled flights and holidays is not the end to summer that passengers or the industry were hoping for. katy austin, bbc news. earlier i spoke to colletta smith at manchester airport. she says the knock on effects are still being felt. even just looking at the arrivals that should be coming in within the next 20 minutes to half an hour here at manchester airport, around five or six, the next five or six flights are delayed or have been delayed, so really frustrated passengers arriving here at manchester airport, lots of them a few hours late, good of them, maybe 2a hours late now arriving back in the uk. it is difficult for customers but they should have had direct contact from the airline in this process so if today you should have been flying, if you were due to fly, it is worth checking with your airline immediately. if you are due to fly tomorrow, the likelihood is we are still going to see knock—on effects so do get in touch and do not travel to the airport until you have heard something from your airline but most airlines are saying most of the flights are leaving the uk as normal. there are some delays but unlikely that many are cancelled. we are seeing a handful right across the uk that are still being cancelled today, as katy was explaining there, because crews and pilots are in the wrong places because of the big delay we saw yesterday. if your flight is cancelled or delayed, the likelihood is that you should get some kind of meal, get a voucher, make sure that you will be covered as a passenger to make sure that you are looked after during that period. lots of people have been given accommodation overnight if their flight was delayed for that evening pair so people returning to the uk should be able to get that refund. if you have had to use alternative rays of travelling, so if you have come via a boat or a train instead or indeed had to book onto another airline, you should be able to claim back that flight and that expense. but it is unlikely in this instance that passengers will be able to get wider compensation because the allies themselves because the airlines themselves were not at fault here, because this was an air traffic control issue. the likelihood as it will be treated in the same way as when there was a storm or some kind of strike at an airport that is beyond the control of the airline and that means the passengers it is unlikely they will get wider compensation, but they should get a full refund for any expenses they had to incur because of a delay or cancellation to their flight. have we heard anything more about what actually caused this problem in the first place? no, and in fact, the air traffic controllers have been very tight—lipped about exactly what happened, probably for understandable reasons. what we have heard from the government is that this isn't a cyber attack. we have heard within the last couple of hours from nats, the organisation that runs the air traffic system, they have said they are very sorry for the impact on passengers and airlines because it is airlines that will have to claim back something from the national air control system for the money they are having to full count for the passages so a lot of the allies are annoyed because i have a big bill in the meantime. but no explanation given for the fault, other than that it has been fixed and they are now operating as normal, but obviously there is a big backlog of passengers to return particularly returning to the uk so it does seems like a lock of passengers are flying out as normal but of course when you have had 2a hours of impact it is likely that a lot of passengers returning to the uk now should have done so a good long while ago, there is a flight here just landing here at manchester airport and it is likely that those passengers may well be considerably later than they had hoped to be. let's bring in paul charles in london, ceo of the pc agency — a travel consultancy. it is maybe not too early to start thinking about the scale of what this disruption has been? obviously it is still ongoing but has there ever been anything like this? there has been nothing _ ever been anything like this? there has been nothing like _ ever been anything like this? there has been nothing like this - ever been anything like this? there has been nothing like this for- ever been anything like this? ti” has been nothing like this for over ten years, since the icelandic volcano that affected so much of uk and worldwide aviation. we have now seen over 1700 flights cancelled in the last 2a hours, which gives you education the significance. we have been totting up the numbers here and we think that the compensation built to airlines alone, the cost to airlines is already between 50 and £100 million. it is a sizeable significant outage and i think the public need to know what caused it, they need more information as to why this has happened. yes. they need more information as to why this has happened.— this has happened. yes, we are yet to hear about _ this has happened. yes, we are yet to hear about that _

have one or two events a year in the uk that causes substantial delays, although not on this scale. the technology was designed over 20 years ago, it was designed over 20 years ago, it was designed in the early 2000 is, in a different area. there were fewer flights, it is over 20 years ago, technology has moved on, and we are now seeing over 6000 flights a day come into our out of the uk. their technology needs upgrading and i think consumers have a right, when they experience such an outage as we had seen at the last 24—hour is, to know what investment is going into this critical aviation infrastructure in the uk so that it doesn't happen again. we infrastructure in the uk so that it doesn't happen again.— doesn't happen again. we really a- reciate doesn't happen again. we really

in pakistan the high court has granted former prime minister imran khan bail. mr khan has been in prison since he was sentenced to three years on august 5th — on charges of not declaring money gained from selling state gifts during his tenure as prime minister. as a result of the conviction, he was also barred for five years from contesting elections. the bail does not necessarily mean that khan will be free to walk out ofjail. here's mr khan's lawyer — gauhar khan — speaking a little earlier. we are very hopeful he will be released. so far, he has not been arrested. we have not been informed that he is under arrest in any other case. if they are going to arrest him in other cases or strategy already online, we have filed cases in the high court and supreme court, and we are seeking the court to restrain the prosecution from arresting him in any other case. our pakistan correspondent caroline davies sent this update from islamabad. the islamabad high courtjust behind me has given imran khan bail in the case that he was found guilty of at the beginning of the month. this is the toshakhana case where he was found guilty of having not declared the money he earned from selling state gifts. imran khan has been in prison since the 5th of august but this doesn't necessarily mean he will be taken out ofjail at this moment, and that is because there are multiple other cases currently out against imran khan and many of them have arrest warrants for him, too. his lawyers have said they will go to the supreme court and here at the high court to try to get him bail across these other cases but even they have said that they think it will be quite difficult to be able to secure that. one of them gave me the odds of a 30% chance that he will actually be released. so, at the moment, it looks like continued legal battles for imran khan and no certainty at all that he will be out ofjail any time soon. around the world and across the uk, this is bbc news. let's look at some other stories making news. redundancies at the collapsed retail chain wilko have been suspended — while rescue bids for the store are considered. unions representing staff have met the administrators but warn wilko is "not out of the woods yet". the chain recently collapsed into administration which has put 12 into administration which has put 12,500 jobs at risk across its 400 uk stores. the government has announced plans to change water pollution rules — to allow more houses to be built. current rules mean councils covering protected areas of england can't allow the building of new houses — unless it's proven that the work won't add phosphates and nitrates to local rivers. critics say — the changes won't solve the root causes of england's housing problems. nhs england has announced there'll be a significant increase in the number of blood pressure checks carried out in the community. the health service says it plans to extend tests in pharmacies as well as offering them in places such as barbers shops and mosques. you're live with bbc news. let's get more now on our breaking news this hour, and a private funeralfor the head of the wagner mercenary group — yevgeny prigozhin — has taken place in st petersburg, according to his press service. with me is our russia editor at bbc monitoring, vitaly shevchenko. this is what has been announced by various accounts and social media linked to wagner. they say a private ceremony has taken place at a ceremony has taken place at a ceremony in st petersburg, that is yet for any prigozhin�*s home city. —— yevgeny prigozhin. that is where his father was buried in this particular seven —— cemetery. state media in russia saying the ceremony was private because that is how his family wanted it to be but it also matches what we think the kremlin once because the kremlin apparently is trying to make sure that yevgeny prigozhin who led an uprising back injune, that she isn't turned into a martyr or a symbol of resistance, so this ceremony being private matches the kremlin�*s wishes as well. so matches the kremlin's wishes as well. ,, ., matches the kremlin's wishes as well, ., , , matches the

on, really, to what happened to yevgeny prigozhin in russia? it really, to what happened to yevgeny prigozhin in russia?— prigozhin in russia? it has been almost a week— prigozhin in russia? it has

yevgeny prigozhin. and across russia, we have seen several spontaneous memorials to which russians have started bringing flowers to pay their respects to wagner and yevgeny prigozhin. and the big question now is what happens to his wagner group? the kremlin and the defence ministry in russia, they want this military company to be amalgamated into the official army, company to be amalgamated into the officialarmy, if company to be amalgamated into the official army, if you like, which is something yevgeny prigozhin opposed, something yevgeny prigozhin opposed, so in the foreseeable future it is reasonable to expect official efforts to take control of wagner, both in russia and in ukraine and also in africa, where various branches of wagner had been operating. branches of wagner had been operating-— operating. and are there any suggestions _ operating. and are there any suggestions emerging - operating. and are there any suggestions emerging of - operating. and are there any|

is reasonable to assume that this is likely to be the end of wagner as we know it. it is going to be really difficult for this military group to reinvent itself in a way that would allow it to maintain any sort of independence from the russian authorities, especially given that we know now that the kremlin funded wagner to the tune of about $1 billion a year, thatis the tune of about $1 billion a year, that is at least what president putin said in the immediate aftermath of the mutiny. so, without this kind of funding, wagner isjust not going to exist. this kind of funding, wagner is

ontario area who later took their own lives. there was a huge matter but if a deal at that and an enormous police investigation in canada. it now appears they have identified another 12 individuals who were supplied by kenneth law who then went on to take their own lives so he now faces a total of 1a charges of counselling or aiding suicide, a quite extraordinary number. and the police in ontario say this is a very active and very compact investigation, notjust compact investigation, not just obviously compact investigation, notjust obviously in canada, they say we are operating with and sharing information with law enforcement on a global scale. they say, we will not tolerate criminal actions by those who prey on the vulnerable in our society, and of course there has been a huge amount of interest here in this country to wear on friday of last week, the national crime agency here reveals that 88 british people had ordered this poisonous substance from kenneth law and had later died, although they couldn't say for sure that the chemical had caused their deaths. they also said that a total of 272 people in the uk had ordered from kenneth law.— from kenneth law. thank

but is likely to be "unnatural", an inquest has heard. sara was found dead at her home in woking earlier this month, sparking a murder inquiry. police in pakistan are looking for three family members in relation to sara's death. helena wilkinson reports from woking. it's nearly three weeks since sara sharif�*s body was found in woking and it's still not clear the cause of death, how the ten—year—old girl died. though at the opening of the inquest here today, they heard that it's likely that it wasn't from natural causes. now, the coroner opened and then adjourned the inquest for a lengthy period of six months because of the complex police investigation. the death of sara sharif has been deeply felt by so many. a ten—year—old girl found dead in her home. she had sustained multiple and extensive injuries. her body was found alone. there is still no sign of her father, urfan sharif, his partner, beinash batool, and sarah's uncle, faisal malik. they left the uk for pakistan the day before sara was discovered. police want to speak to them in connection with their murder investigation. soon after landing in islamabad, it was sara's father who rang the emergency services in the uk. it was his call which led officers to the family home. today at surrey coroner's court, an inquest was opened and adjourned for six months. the coroner said he wouldn't normally grant such a lengthy adjournment, but did so because of the complexity of the case and the international element of the investigation. while police continue to work with authorities in pakistan, here in the uk officers are working to piece together a picture of sara's life. well, in terms of that international investigation, as far as we've been told, there is no trace of sara's father, his partner and sara's uncle. but we have been told by police in pakistan on the ground who are conducting this search on behalf of surrey police that they are widening the area, covering four areas in the country. and they are doing so, they say, because they've received new information from multiple sources. in london, there's some dispute about how much of an impact the ulez scheme will have on public health in london. but there is considerable evidence that pollution can pose a significant risk. a new report by the energy policy institute of chicago says that living in an area with poor air quality can take an average of 2.2 years off live expectancy, making it one of the greatest external risks to human health. here's how researchers say air pollution harms human health. it can affect the brain in foetal development. it's linked to heart attacks and cardiovascular diseases. it can lead to lung cancer — and also can affect the pancreas with type 2 diabetes. it is basically about how bad it is and they have listed all the different regions in the world, for example south asia tops the list, africa and southeast asia, and they are talking about the intensity of the fine particulate matter, how the emissions of the pollution is increasing. so, on average, with a figure of 13% compared to what it was ten years ago, and in some countries it is much more. and what they are saying is these countries where you see all these concentration of this particular matter, pollutants, they don't have proper policies, and also they are not open about their data, about their air—quality data. also, they are not able to introduce a proper policy to control air pollution. and also the bigger picture here is the globalfund to deal with also the bigger picture here is the global fund to deal with air pollution is quite missing there, so they have compared money. example, it goes to malaria, hiv, that's $4 billion a year annual, compared with 300,000 only for the whole of africa, $300,000 for africa to deal with air pollution, so they are saying the funding is also a major issue here. the saying the funding is also a ma'or here.— issue here. the report also said that south _ issue here. the report also said that south asia _ issue here. the report also said that south asia is _ issue here. the report also said that south asia is the _ issue here. the report also said that south asia is the worst - that south asia is the worst affected region, can you explain why thatis affected region, can you explain why that is and what are the sources of this air pollution there? 50. that is and what are the sources of this air pollution there?— this air pollution there? so, you know, this air pollution there? so, you know. the _ this air pollution there? so, you know, the major _ this air pollution there? so, you know, the major thing _ this air pollution there? so, you know, the major thing what - this air pollution there? so, you | know, the major thing what they this air pollution there? so, you - know, the major thing what they had said is 7%, only 7% of the countries in the region have been able to talk about their data openly. what this air quality is like, the data and only 35%, they talk about what is your standard? does it meet the who standard? there is a big gap here. and they are also talk about the sources. as you know, these countries are fast rapidly developing all these infrastructures of element, so definitely industries and regular emissions and —— of regular emissions are not to forget what you get from all the burning off from agriculture every year, these all accumulate and the air quality continues to degrade. details there of the report. just imagine the breaking news we have had this hour, the head of the wagner mercenary group, yevgeny prigozhin, has been buried in st petersburg, according to his press service. prigozhin who led the wagnerfighters injune service. prigozhin who led the wagner fighters injune was one of ten people on board a private plane that crashed in russia's last week, you may remember that, and now we're hearing the news that he has been buried in st petersburg a private ceremony that russian authorities say was private because that was the wish of his family. we'll bring you more here on bbc news as we get it, you are watching verified live, stay with us, much more to come, including all the latest in the business news. don't go away. hello. bit of a mixed bag in this final week of meteorological summer. back to school soon as well. and here's the weather headline for the outlook. sunny spells and scattered showers. that's what we're expecting pretty much for the rest of the week. now, here's the satellite picture and you can see some clouds circling around scotland. here are the temperatures for today, modest glasgow at 16, 18 in liverpool, 17 for birmingham. and we should nudge up to 21 in london and norwich. so the low pressure is with us pushing in the showers from the north, pushing them southwards. there'll be some clear spells around two and early in the morning on wednesday quite nippy in some areas. seven degrees for glasgow, will be colder in rural spots and many parts of england and wales also into single figures. so lots of sunshine tomorrow but with a northerly airstream, that northerly cool air showers are also going to be building up. the sun will propel those clouds and we'll see those temperatures of around 18 to about 20 degrees celsius. so a few showers in the forecast, i think, for wednesday. now let's have a look at thursday's weather map. an area of low pressure approaches. here are the weather fronts. so early in the day, i think rain spreading across wales and southern parts of england. i think the further north you are on on thursday, the better the weather will be. so, hull newcastle certainly the lowlands of scotland, aberdeen fine weather on thursday where else? out towards the west and the south. there will be rain at times and those temperatures again, high teens in the north, about 18 degrees expected in the south of the country, 18 or 19. so that's thursday. now, this is the jet stream here with the weather map. you can see sort of looping, just diving before us. but high pressure is starting to build through the weekend. so there is an indication that actually this weekend the weather's not looking bad at all, some sunshine and actually pleasantly warm. so for once, the weather is going to behave this coming weekend. that's it. have a good day. bye. this is bbc news, the headlines: the wagner mercenary group says its founder — yevgeny prigozhin — has been buried privately in st petersburg — after his plane crashed last week. downing street calls on airlines to fulfil their
