Hello and welcome to our special coverage here on bbc news, as we mark 20 years on from the terror attacks on New York and washington. Attacks that killed nearly 3,000 people and that have forever been known by the date on which they happened 9 11. Commemorations will be taking place in manhattan and across the united states, to remember all those killed and injured. 0ur North America Editor Jon Sopel has been hearing the stories of three people impacted by the horror of september the 11th, and a warning his report includes footage of the attack on the twin towers. The one thing that time hasnt dulled is just how profoundly shocking the sights and sounds were that Tuesday Morning two decades ago. This Terrorist Attack changed the world. Nearly 3,000 people died and thousands more had their lives upended. This is the story of three of those people who found themselves at the vortex of the storm. My dad was an amazing human being. Max giaccone 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. Youre an innocent ten year old thinking, the world is great, and then you find out that someone killed your father. Hundreds of miles south in florida, Andy Card was also at an elementary school. The Chief Of Staff to President Bush knew he had to interrupt him. Thats 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 Van Hine was in her car when she heard the news, and she knew as people were trying to escape the twin towers, her firefighter husband, bruce, would be heading in. My kids went to bed. Emily and megan were 17 and 1a at the time. I stayed dressed, i laid down with them, but i didnt go to sleep because i figured someone was coming to the house and i didnt want to be in my pyjamas. Its 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, whod harboured the alqaeda 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 were 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 its 9 11, whether its january 13th, whether itsjuly 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. And 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 a much more introspective place. Jon sopel, bbc news, New York. The 9 11 attacks led to the invasion of afghanistan. Two decades later the taliban are back in power and presenting a new face to the world. Theyve promised to forgive those who fought against them and to respect womens rights to work and education. But many afghans are still fearful of what the New Order will bring, as Secunder Kermani reports from kabul. Back in the classroom. This was amongst the first schools in kabul to reopen for girls after the fall of the taliban in 2001. They, along with female teachers, had been banned by the group. Two decades on, The School has expanded. Pupils have gone on to become doctors, engineers. Aisha misbah has worked here for the past a0 years. This time round, the taliban are allowing girls to get an education, but all Secondary School Classes are currently paused, awaiting new rules from the group. Pupils here face other challenges, too. Pleas to the previous government for new buildings went unanswered. Educating generations of young afghan girls and boys has been one of the main achievements of the past 20 years. But you also have to ask why a government that received billions of dollars of international Aid Couldnt even build enough classrooms for pupils in a school in the very centre of kabul . Many would blame corruption. This is a generation determined to make its voice heard. Covering recent protests, what had been one of the freest medias in the region, now its under threat. These two journalists were badly beaten by the taliban after reporting on a demonstration. American influence here is fading. This is bush bazaar, named after the us president. The Military Gear on sale used to come from international troop bases. Now its largely chinese made imitation, to the disappointment of taliban fighters, now the main customers. 20 years of war have left a legacy that is increasingly unclear. Secunder kermani, bbc news, kabul. The head of Britains M15 says the threat of terrorism in the uk remains a real and enduring thing. Ken mccallum revealed that 31 late Stage Attack plots had been foiled here in the last four years. And he warned that more sophisticated groups could reform once again. 0ur Security Correspondent Gordon Corera reports. 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 Uks Terror Threat level has fluctuated, spiking up around 2006 when alqaeda plots were coming out of pakistan. And then again around a decade later, linked to isis in iraq 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 again drawing it back to worry 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. Afghanistan is not an easy country to govern and within which to ensure perfect security. 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. We can speak now to javed ali, whos a former us national Counterterrorism Director on the national security council. Javed was in washington on that day, and had just passed the pentagon 30 minutes before it was attacked. I will come to your personal memories in a moment. The us Secretary Of State said shortly after 9 11 history start today. He was right, really, in terms of what we have seen in the past 20 years . Of what we have seen in the past 20 years .

Thank you for| having me on. 9 11 was such a profoundly moment in not only us history but i would argue in international history and has really shaped the trajectory of the last 20 years in ways that was very difficult to know in those early moments right after 9 11 and i would argue going back to some of the points raised in earlier pieces of your segment, they have been elements of those past 20 years that have led the us, britain saved so we have had some Counterterrorism Successes, many Counterterrorism Successes and achievements, but sometimes they have come at a higher cost and big clear eyed about this last 20 years, we have to recognise they have been several strategic errors as well and one of these lessons is to not repeat the same mistakes going forward. What has america mistakes going forward. What has america and mistakes going forward. What has america and the mistakes going forward. What has america and the west has america and the west achieved in afghanistan . This is another achieved in afghanistan . This is another one achieved in afghanistan .

Ti 3 is another one of those important questions. 0n the one hand, because of 20 years, up until recently anyway, 20 years of sustained Counterterrorism Pressure through the us, britain, nato, different partnerships and different afghan governments over time, Alqaedas Ability to threaten the west, whether the us, britain, was significantly diminished and reduce. That was not necessarily the case in the early years after 9 11. I was in government then and to see the amount of Attention Alqaeda was still putting on, it was really shocking to see. Despite all the relentless operations directed against them. On the one hand, Alqaedas Ability to threaten the us and the west has been diminished, nowhere near it was before hand. At the same time, the us and western withdrawal, the us and western withdrawal, the collapse of the government, now we have a different Operating Environment in afghanistan and we do not know is your previous reporter alluded to, we do not know if the taliban will be able to maintain a high level of Counterterrorism Security in the country and guarantee the security of the west as a result of that.

Lawyers acting for virginia giuffre, the woman who claims she was sexually assaulted by Prince Andrew, say he has been served with legal papers, ahead of preliminary proceedings scheduled to take place in New York on monday. 0ur Royal Correspondent Sarah Campbell has more. These are the official legal papers relating to the civil case that was brought by virginia giuffre, and she alleges that she was sexually assaulted by Prince Andrew when she was 17 years old. He denies all the claims made against him and he said that he has no recollection of meeting her. But this civil case was launched last month at a court in New York, and as part of that initial process, papers must be served on the defendant, so Prince Andrew. Now, a document published today by the court indicates that miss giuffres lawyers believe this has now been done. It describes how their representative left the papers with a Police Officer at Prince Andrews home, royal lodge in windsor, and that was on the 27th of august. Now, what isnt clear this evening is whether the princes legal team agree that those papers were served correctly. We have contacted them, but theyre not commenting this evening. It will be now for a judge to decide whether the case will proceed and how it will proceed. And there is a Telephone Conference scheduled for Monday Afternoon in New York between her lawyers and the judge, so that will give us some clarity of how this case is going to proceed. And in the meantime, Prince Andrew, we know, is in balmoral in scotland. Sarah campbell reporting. Lets get some of the days other news.

Hello there. We had some intense showers to end friday across eastern scotland, eastern england, some rumbles of thunder. And a lot of rain also from those showers in Northern Ireland. This is just how it looked in those showers, for example, at Lowestoft In Suffolk on friday afternoon. Now, we should see fewer showers at least through saturday. In fact, for much of the weekend. But there is a Question Mark over sunday. And thats because we should see a little bit more sunshine, things turn a little fresher, as this area of low pressure responsible for these showers starts to move away to the northeast. We are left with wet weather across Northern Scotland because of this trailing weather front. But behind that weather front, we shift the Wind Direction into the north and the northwest, so it freshens up, because at the moment, we still have that humidity. That will start to ebb away during saturday. But we also have that wet weather in the north. Its already been pretty wet in shetland, and by morning, widespread rain across the north, scotland some quite Heavy Rain as well. Elsewhere, the showers tending to easy away, but a Muggy Night again, 1a or15. Lots of grey, misty, murky weather in northern and western areas, drizzle over the hills, some potential Hill Fog as well. But that cloud should break up, and so for england and wales, fewershowers, brighter weather, a bit more sunshine than we had during the day on friday. Still a scattering of showers for Northern Ireland, best chance of sunshine in the south and the south of scotland. But for the north of scotland, itjust continues to be a pretty wet affair. A real soaking rain, so well need to keep an eye on that for localised flooding. A little bit fresher in the north, but still quite warm in the sunshine in southern and eastern areas. And thats because we have got a Ridge Of High Pressure here. By the time our Weather System starts to drift southwards, it does peter out and eventually becomes drier for Northern Scotland under a Ridge Of High Pressure, but this is the Question Mark, what comes in from the west. But for sunday, you can see perhaps a little bit of cloud, a breeze and some rain for the Great North Runners here. Weve got a lot of dry runner elsewhere and it becomes drier for scotland and Northern Ireland than recent days, but its how far north and east this rain comes. Its giving us a headache at the moment. Looks like the southwest and wales will bear the brunt during the course of sunday. This is bbc news, the headlines President Biden has appealed for national unity ahead of the commemorations, 20 years on from the 9 11 attacks on the united states.
