heathrow saw the highest number of cancellations, followed by gatwick and manchester. there were also reports of thousands of passengers stranded in airports overseas. the technical fault was repaired within hours but the impacts continue today, with an estimated 281 flights affected so far. this is liverpool airport, where there's been confusion over cancelled departures. our transport correspondent, katy austin, reports. 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. our flight has been scheduled 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 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 ours. 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 about our flight cancellation. 0n 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. laurence blight is stuck in benidorm, spain — after his flight was cancelled yesterday. he shared a little bit about his experience. it's been a shock, really. we were on the bridge, as you do, scrolling through tiktok and i see a video regarding what's happening in the uk, so we thought we'd better look at the easyjet app and it was only then that we discovered we were delayed by about five hours. we took another look about half an hour later, led by another six hours, and before you know it flight was cancelled and we were effectively stranded in alicante.— cancelled and we were effectively stranded in alicante. where did you no? i'm stranded in alicante. where did you go? i'm with _ stranded in alicante. where did you go? i'm with a _ stranded in alicante. where did you go? i'm with a couple _ stranded in alicante. where did you go? i'm with a couple of _ stranded in alicante. where did you go? i'm with a couple of friends. i go? i'm with a couple of friends. after a coume — go? i'm with a couple of friends. after a couple of— go? i'm with a couple of friends. after a couple of hours -

to accept that he is gone. it is only when i am here that it sinks in. i feel he is still somewhere. that he is still alive, and on a mission, doing hisjob. in marriage, 0ksana made a pact with her husband that she would join up if he was killed in action. she is still getting used to army life and the dangers that come with it. this road is regularly shelled. here, outside bakhmut, they head out and immediately take cover in nearby woods. this position is in range of russian guns. like thousands of other ukrainians, 0ksana had very little time to mourn. instead, she chose to fight. what we hear from a lot of soldiers on the front line is that the time to grieve will come when the war is over. in poland, at least 1a people have died and more than 150 are in hospital following an outbreak of legionnaires' disease. it's happened in the south—eastern city of rzeszow. authorities are checking whether the legionella bacteria entered the city's water supply. security services say there's no evidence of sabotage. 0ur correspondent in poland — adam easton — gave us this update. what we know so far is that, as you mentioned, 1a people have died and more than 153, to be exact, are in hospital after becoming infected with legionnaires' disease. the investigation is ongoing as to how these people came into contact with the contaminated water. there has been additional chlorine added to the water supply system in the city, although, at this stage, the initial tests on the water have not proved conclusive either way. whether the actual city's water supply system somehow was the source of the bacteria, the legionella bacteria, which causes legionnaires' disease, or if it was something else. we don't know at this stage because there is too little in terms of the testing and results that have taken place. what we do know is that the people who have been affected are generally elderly, and all of the people who have died have been suffering already from other serious illnesses. if you're in the uk you're probably familiar with the term ulez. it stands for ultra low emission zone and london's scheme has just been expanded to cover the whole of the capital. owners of the most polluting vehicles, have to pay £12.50 a day if they drive in the area. london now has the world's largest ultra low emission zone, but other these were some of the first cars to enter the new expanded ultra low emission zone. from midnight, olderand more polluting vehicles passing these signs need to pay a daily charge of £12.50. the mayor's office says it is all about improving the air quality of the capital, preventing deaths like that of ella adoo—kissi—debrah. in 2013, she died following an asthma attack. she was the first person in the uk to have air pollution listed as a cause of death. it is a disgrace that in 2023, we still have the worst asthma deaths in europe. it is unacceptable and boys especially, between the ages of 13 and 15, appear to be the most vulnerable. enfield in north london is one of the areas now in the zone. we've had to change both our cars but if it's going to help the environment then i think that's a good thing. we've still got the old model of car so it's not ulez compliant. - that's going to be 12.50 every day but i'm going to have to make - either a lot of changes and start walking... i i mean, i take my son to school, i go and visit my elderly mum. . it doesn't sound a lot but it is when you have to pay that every day. now this is where the ultra low emission zone used to start — the south circular. but from today, it goes miles that way and any car driving these roads that isn't compliant has to pay the charge. it's faced opposition, with some conservative councils refusing to put up signs. if you look at the mayor's own impact assessment, it will have a minor to negligible effect on air quality. so it's very clear — despite what the mayor says — this isn't about improving the air quality in greater london, it's about raising money from londoners for him. this is about helping our air be cleaner and in a couple of years' time, tfl have predicted there will be no additional money made because of the number of noncompliant vehicles, but every penny net made is used to reinvest in public transport. the details around this scheme are hotly disputed, from the impact on air quality to the number of cars affected. whatever the arguments, london's expanded ultra low emission zone is now here and the cameras are in action. joe inwood, bbc news. so — as we've been hearing — there's considerable 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 two point two years off live expectancy, making it one of the greatest external risks to human health. a short while ago we spoke to navin singh khadka, who explained more about the report. this report talks about some of those countries we have been talking about for many years, mostly in south asia, some in africa and also in south—east asia. what they are saying is that basically governments particularly in these countries, the majority, for example, only 7% of governments in south asia provide the actual full data on air pollution, air quality, and only 45% of those governments have air quality standards, which explains by and large where this is lacking, because it starts from that. this despite the warning we are hearing from the who that 7 million people die because what they call indoor and outdoor air pollution. if you just talk about outdoor, it's more than 4 million people a year. despite this, there is a huge policy gap in these governments. in question on tackling air pollution and climate change, some pollutants can cause more. i and climate change, some pollutants can cause more-— and climate change, some pollutants can cause more. i reported this many ears auo can cause more. i reported this many years ago when _ can cause more. i reported this many years ago when there _ can cause more. i reported this many years ago when there was _ can cause more. i reported this many years ago when there was this - years ago when there was this argument that, if you tackle air pollution, automatically you'd be tackling climate change, with c02 or other air pollutants. but the thing is, recently, iattended other air pollutants. but the thing is, recently, i attended a other air pollutants. but the thing is, recently, iattended a major other air pollutants. but the thing is, recently, i attended a major un conference where i was hearing people actually say it's the other way round, because many governments have failed to do that and so what they are saying is perhaps we need to stress climate change and then address climate change then automatically perhaps they'll be dealing with air pollution. it remains to see if that happened but it's a major challenge. if remains to see if that happened but it's a major challenge.— it's a ma'or challenge. if you want to read it's a major challenge. if you want to read or — it's a major challenge. if you want to read or hear _ it's a major challenge. if you want to read or hear more _ it's a major challenge. if you want to read or hear more about -
