i've been taking care of each day, and three — i've been taking care of each day, and three weeks later, i'm in the final_ and three weeks later, i'm in the final and — and three weeks later, i'm in the final and i— and three weeks later, i'm in the final and i can't actually believe it. and coming up, foreign correspondents based in london will be discussing social care and afghanistan. that's in half an hour in dateline. good afternoon and welcome to bbc news. we start with a warning from the head of m15, who says there is no doubt that recent events in afghanistan, and the rise of the taliban, are likely to have emboldened so called "lone wolf" terrorists. ken mccallum told bbc news that 31 late stage attack plots have been foiled in the uk in the last four years. the taliban has promised that afghanistan would never again be a base for terrorists after taking over the country last month.

the m15 warning comes on the eve of the 20th anniversary of the 9/11 attacks. we'll have more that in a moment, but first, here's our security correspondent gordon corera on ken mccallum's comments. for 20 years, surveillance and security have become ever more entwined in our lives — a sign of a threat that has not gone away, as the head of m15 told the bbc today. we do face a consistent global struggle to defeat extremism and to guard against terrorism. this is a real problem and in the last four years, for example, working with the police, my organisation has disrupted 31 late stage attack plots in great britain. a new counterterrorism operations centre was launched this summer by m15 and the police but the threats have also been changing. since 9/11, we have had a continued evolving huge challenge with islamist extremist terrorism.

we have the rise of extreme right—wing terrorism and we have definitely a resurgence of sharp and complex state threats. the only major national security threat which has been comparatively better across those 20 years is northern ireland. the uk's terror threat level has fluctuated, spiking up around 2006 when al-qaeda plots were coming out of pakistan. and then again around a decade later, linked to isis in iran and syria. but the hope was that it might now decline. m15 has been trying to focus on wider issues like espionage and foreign interference, but the landscape has just changed once the landscape has just changed once again, drawing it back to worrying more about jihadist terrorism. the concern is that the taliban takeover in afghanistan may both inspire extremists here and perhaps create a safe haven there for groups to plan more sophisticated attacks. there is no doubt that recent events in afghanistan will have heartened and emboldened some

of those extremists. so, even if the taliban is absolutely in good faith about wanting to prevent terrorism being exported from afghanistan, that will be a difficult task to accomplish. m15 may have expanded and we all may live with more surveillance m15 may have expanded and we all may live with more surveillance and security, but asked if we were safer now than 20 years ago, the head of m15 said there was no simple answer. gordon corera, bbc news. thank you very much forjoining us. what change in terms of the operation in the wake of 9/11? well, very aggressively- — operation in the wake of 9/11? well, very aggressively. in _ operation in the wake of 9/11? well, very aggressively. in the _ operation in the wake of 9/11? well, very aggressively. in the wake - operation in the wake of 9/11? -ii very aggressively. in the wake of 9/11, it was a horrific way flip fall for all the intelligence agencies who had been dealing with terrorism on a much more microcosm level —— since that time, and

particularly on 9/11, it was a wake—up call to the set driver gets. where a number of different targets were attacked simultaneously. mb? were attacked simultaneously. why haven't the intelligence agencies seen something like 9/11 coming? not necessarily the actual act, but something on the scale. in the united states, _ something on the scale. in the united states, although - something on the scale. in the united states, although they l something on the scale. in the - united states, although they have intelligence capabilities. the measures and steps that were taken by al-qaeda to finance this operation were very, very complex. the way that they left it as such a sufficient amount of time. this was planned over a significant period of time. now, those kind of operations

have been able to be diffused and intercepted because if there is a large planning cycle, that makes it easier for large planning cycle, that makes it easierfor the large planning cycle, that makes it easier for the intelligence agencies to pick up at some stage. the head of mis to pick up at some stage. the head of m15 was staying they were able to stop attacks on the later state, but when they're spontaneous, they are incredibly difficult to stop. h0??? incredibly difficult to stop. how much better— incredibly difficult to stop. how much better equipped are the intelligence agencies now? bearing intelligence agencies now? bearing in mind the nature of terrorism can change, can transform itself very quickly. sometimes you deal with large next works and the people who are asking alone. figs large next works and the people who are asking alone.— are asking alone. as we've seen with the islamic — are asking alone. as we've seen with the islamic state, _ are asking alone. as we've seen with the islamic state, al-qaeda - are asking alone. as we've seen with the islamic state, al-qaeda have - the islamic state, al-qaeda have looked at your lone wolves to carry out these attacks. we have to look at the advancement in technology, and when one imagines that iphones only came out and i believe 2007, we

now look at the smartphone devices that we have in our pockets right now. technology has advanced on many platforms, which can be advantaged not only by the terrorists, but especially groups like gc hq and the nsa in intercepting and identifying particular groups of chatter or propaganda that could be pushed out. will geddes, it's good to talk to you. no doubt more conversations in the coming weeks.— tomorrow marks the 20th anniversary of 9/11, the deadliest foreign attack ever on us soil. almost 3,000 people died as suicide attackers highjacked four passenger planes crashing two of them into the twin towers in new york. 0ur north america editor jon sopel has been hearing the stories of three people impacted by the horror of that day, and a warning, his report does include footage of the attack on the twin towers. the one thing that time hasn't

dulled is just how profoundly shocking the sights and sounds were that tuesday morning two decades ago. screaming this terrorist attack changed the world. nearly 3000 people died and thousands more had their lives upended. this is the story of three of those people who found themselves at the eye of the storm. my dad was an amazing human being. max was a ten—year—old schoolboy when he was called to the principal�*s office. his father, joseph, worked at the world trade center. i went down the hallway, and my mum was standing there with tears in her eyes. she told me what had happened, and we had a moment in the hallway. i think i was just very confused at first. you're an innocent ten—year—old thinking, "the world is great." and then, you find out someone killed your father.

hundreds of miles south in florida, andy was also at an elementary school. the chief of staff to president bush knew he had to interrupt him. that's when i walked up to the president and i leaned down and i whispered to him, "a second plane hit the second tower. america is under attack. " ann was in her car when she heard the news, and she knew as people were trying to escape the twin towers, herfirefighter husband, bruce, would be heading in. my kids went to bed. emily and megan were 17 and 14 at the time. - i stayed dressed, i laid down - with them but i didn't go to sleep because i figured someone was coming to the house and i would _ be in my pyjamas. it's weird, the things you worry about. - and at about midnight, somebody came to the house to say that bruce _ was unaccounted for. this memorial, with great restraint, does justice to the terrible

events of that day. but nothing can capture the sense of chaos, anger, disbelief of what was unfolding. then, there was steely resolve, and americans were united and most of the rest of the world stood with america. the taliban in power in afghanistan, who'd harboured the al-qaeda terrorists, would be driven from power and the us would try to replace the warlords with democracy. but 20 years on, america has abandoned afghanistan. i think we're still the greatest democracy in the history of the world, but we are not shining the way we used to shine, and, yes, we are tarnished. i do think it has been a defeat for the pride of america and the respect that we have had around the world. 20 years ago, america was never more united. two decades on and the terrorist threat largely quelled,

and america has never been more divided. the way we came together was... it was awe—inspiring. and in 20 years, the pendulum has . swung, in my opinion, the other way. every day, i miss my dad. every single day. whether it's 9/11, whether it's january 13th, whether it's july 7th. i miss my dad and that will never change. and so to 2021, and the most powerful country in the world seems to be suffering a crisis of confidence. in the manner of its departure from afghanistan, the kabul debacle, a crisis of competence. just off the tip of manhattan, lady liberty symbolises america opening its arms to the world. but 20 years on, the us feels much more introspective place. jon sopel, bbc news, new york.

revisiting of that anger, of that fear, of that real incredulity that was experienced on 9/11. how could this happen in america, to america? i think also a lot of contemplation of what came in the 20 years after that — the war on terror, and those questions are very real right now. given what we've seen in terms of the american withdrawal from afghanistan, the way it was done and who took over. afghanistan, the way it was done and who took over-— afghanistan, the way it was done and who took over. gary, for the moment, thank ou who took over. gary, for the moment, thank you very — who took over. gary, for the moment, thank you very much _ who took over. gary, for the moment, thank you very much indeed. - who took over. gary, for the moment, thank you very much indeed. gary - thank you very much indeed. gary 0'donoghue in washington. scotland's first minister says the nhs is under more pressure before with one in 45 people having a virus last week. in england, the culture secretary has said vaccine passports

were almost certainly required this autumn, along with boosterjabs for the elderly and vulnerable. here's our health editor, hugh pym. a pop—up testing site in glasgow. a scottish infections increase, the first minister has told the bbc that covid has contributed to increasing strain on hospitals. i have never known a period where the nhs has been under pressure that is as intense as it is now. right now? yes, and that is ahead of winter. the vaccine passports will be required in scotland at nightclubs and some large events from 0ctober1st. nicola sturgeon didn't rule out extending that and there was a similar message from ministers in england. we will almost certainly be doing it for nightclubs. we will make a determination as to whether we need to move more more broadly than that. the office of national statistics infection survey suggests

one in 45 people in scotland had the virus last week, the highest since the survey began. in wales, there were increases to one in 65. in england, at one in 70 and northern ireland at one in 60 people, there was no change broadly. four out of five of those eligible have had both eligible have had both vaccines, but that leaves work to be done for health chiefs trying to persuade more people to come forward forjabs. after a surge, as the programme was rolled out, vaccination rates in england have been tailing off in most age groups. amongst the oldest nearly 100% have had a first dose, it is 60% for younger groups. it's still rising among 16 and 17—year—olds. a decision by the vaccine expert committee is due soon on booster jabs. there are varying views on how necessary they will be. to get good protection

after a single dose and then improved by a second dose, and we would expect it to be maintained or improvedbe athird dose. maintained or improved be at hird dose. we wait to see. but getting the first dose is port. some argue priority groups could get a third jab. there's a strong case for some people to be offered booster vaccines and a case for people over 80, people who would not necessarily have responded to the initial vaccine. the nhs is ready to roll out boosterjabs and to start vaccinating 12 to 15—year—olds, if experts give the green light. hugh pym, bbc news. joining us... and professor of immunology at imperial college london. welcome to you both. thank you forjoining us. let me start

been lining up to heap praise on emma raducanu. the 18—year—old is yet to drop a set at the us open and the 18—time grand slam champion martina navratilova says it's even more impressive that she has reached the final as a qualifier, which has never been done before. the speed with which she did it... nobody could have respected it —— predicted it. she didn't get the wall wild card, she didn't waltz here, saying,... and i think it paid off because she didn't play that well at the beginning of the tournament in the qualifying, but it grew and each match, got better and better... we knew she was going to get better. but again she has just taken it to another level here and it's very impressive. former england captain michael vaughan has criticised the decision to call off today's fifth and final test between england and india just two hours before the match was due to start at old trafford. a number of india's backroom staff tested positive for covid—19 and they were so concerned about it

spreading to the playing squad that it was decided they wouldn't be able to field a team. i'll be honest, i think all this is about— i'll be honest, i think all this is about money. i completely get players — about money. i completely get players and what they've gone through — players and what they've gone through in the last year. it's been difficult — through in the last year. it's been difficult. the mental health side is very important. we have to look after _ very important. we have to look after that — very important. we have to look afterthat. i very important. we have to look after that. i believe this week was about— after that. i believe this week was about money, making sure those players _ about money, making sure those players get to the ipl, because they want to— players get to the ipl, because they want to earn those big checks, but i don't get _ want to earn those big checks, but i don't get it— want to earn those big checks, but i don't get it when it's at the expense _ don't get it when it's at the expense of the test match. formula one is experimenting again this weekend with its new sprint race format to decide the grid for sunday's italian grand prix. the traditional style of qualfying took place this evening and in the week he was told he'd be leaving mercedes at the end of the season. valtteri bottas had the last laugh topping the timesheets. he'll start saturday's sprint race ahead of lewis hamilton and championship leader max verstappen. that's all the sport for now.

coming up now, it is the weather with helen willetts. good evening. with low pressure, it has been a showery picture. sunny spells between the showers as we saw in suffolk, but we've also seen a lot of lively showers and through the second half of the afternoon across the eastern half of england. the weekend will bring fewer showers for many of us, but it'll feel fresher, and the region — the low pressure is moving out into the north sea. bringing wet and windy weather to scandinavia. we still got the remnants, but the change i talked about is the wind direction. it's a fresher feel. you can see the heat gradually through the day on saturday. still a few thunderstorms. possibly one or two in northern ireland. but they fade away through the night. the wet areas really

dominated by the low pressure across north scotland, notjust tonight, but tomorrow as well. the most —— for most of us, it's misty and great and quite warm. we haven't lost that humidity yet. quite a warm start, but also quite misty, particularly over the hills but there could be fog. it does take a little longer to clear and once it does so, some brighter spells coming through. still a scattering for northern ireland, but not as many as today. fearing quite well for drier weather, but it is really looking quite wet across northern scotland. temperatures dropping away, a fresher feel and generally quite brisk breeze. that weather front weekend, but there is a fly in the ointment. how far north and east it will spread its influence of the time we get to sunday. cloudier for the east of scotland on that

weakening weather front, the east of scotland on that weakening weatherfront, but the east of scotland on that weakening weather front, but drier further north and brighter. fewer showers for northern ireland and further east, some drier weather. it could be that weather front gets stuck across western areas, so by monday, most of the rain... quite a bit of uncertainty surrounding that next area of low pressure at this stage. we'll keep up to date.

hello and welcome to dateline london. i am martine croxall. this week our discussion is all about money. here in the uk the government has announced the biggest set of tax rises since the second world war. the imf, the world bank and about banks everywhere are trying to decide whether they will release afghanistan's frozen assets and thereby avoid humanitarian

disaster. 0ur guest this week... the
