who was also an al-qaida bomb maker has been convicted of planning a terror attack in westminster, and making explosive devices in afghanistan. 28—year—old khalid ali was arrested by downing street in april last year after his mother called the police saying she had found knives in his bedroom and was scared he was going to kill the family. he'd returned to the uk in 2016, and his fingerprints were later found to match those on bomb components recovered from aghanistan. daniel sandford reports. go back, go back, go back, go back. bleeding, mate, bleeding. you got him? the moment when armed officers stopped an al-qaeda supporter launching a knife attack on whitehall. do you have everything on you that may hurt us, or hurt anyone else? it was april last year, barely a month after the traumatic westminster bridge attack. another knife. third knife! khalid ali was carrying three brand—new knives. he had bought them just

two hours earlier. he had been born in saudi arabia to a somali father and an ethiopian mother, and he grew up in north london. he first came to the security service's attention on an aid convoy to gaza in 2010. taking it to the next level. you feel me? 0ne love. that's the real thing about this kind of mission... kieren turner helped organise the convoy and told me he remembers ali well. at that point i thought, a nice young man, this will be one of the people that's fun to travel with. he had a sense of humour. i remember him because he always smiled. also on the convoy were some die—hard extremists, including thomas evans, who was later killed fighting in kenya. within a few months, khalid ali was himself in afghanistan, where he joined al-qaida. his fingerprints, later found by the americans on these detonators and remote controls seized in the south—east of the country. in police interviews, he admitted setting off 300 bombs himself.

how many times have you pressed the button to cause an explosion? probably more than 300 times. more than 300 times? when khalid ali suddenly returned to heathrow in 2016, suspicious counterterrorism officers took his fingerprints. when these were checked with prints kept by the fbi at this huge warehouse of improvised bombs in warzones. he was seen outside downing street in april and is mother warned the police she found knives. that day, police she found knives. thatedey.l bought three more knives and he bought three more knives and headed to westminster, dropping his phonein headed to westminster, dropping his phone in the river thames and his tube ticket in the rubbish bin. having dumped the evidence and now carrying an empty backpack and three knives, callard ali —— khalid ali headed towards downing street. he was ready but at this point so were the police. the al-qaeda bomb maker

and been stopped just 200 metres from downing street. daniel sandford, bbc news, whitehall. two men have been killed and 12 others injured, in a crash between a double—decker bus and a lorry in cambridgeshire. police say five of those caught up in the accident on the a117 have serious injuries. 0ur correspondentjo black is at the scene for us now. jo, tell us more about what happened. yes, as you can see, the road has just reopened in the last half an hour after being closed for around ten hours. it was this afternoon that police confirmed that two people had lost their lives in the crash. among those taken to hospital, people suffering brain injuries and a broken nose. just after 7:30am, the emergency services were called to this, a terrible crash between a ali—tonne lorry and a double—decker bus on the busy a117 near guyhirn in cambridgeshire. two men, the bus driver, in his 50s, from norfolk, and a passenger, a man in his 70s

from northamptonshire, both died at the scene. 12 others who were also on the bus were wounded, some of them seriously. when we're talking about, an hgv, an articulated lorry, and a double—decker bus, two very, very big vehicles on the road there, possibly the biggest vehicles on the road. for me, i'm astounded there wasn't more casualties. the crash, which involved a bretts lorry, happened just behind me near the firm's distribution centre. it's thought the bus collided into the side of the hgvjust as it was pulling out of the company's yard. in a statement, the bus company first eastern counties said they were shocked and saddened by what happened. investigations into why this happened are now under way and in the meantime, police are appealing for witnesses and any drivers who may have dashcam

footage of the incident. jo black, bbc news. let's take a brief look at some of today's other news stories. a couple who tortured and killed their nanny before dumping her body on a fire in their garden have both been jailed for a minimum of 30 years. during their trial, the court heard how sabrina kouider and partner 0uissem medouni murdered sophie lionnet because of their bizarre belief she was plotting to abuse people in their home, with the help of an ex—boyzone singer. investment in britain's car industry has fallen by half, according to figures from the motoring sector. the society of motor manufacturers & traders says uncertainty due to brexit is preventing firms putting money into factories in the uk. but the government insists the industry is a success story and they are working hard on a brexit deal. the mini cab hailing firm uber has had the ban on its license to operate in london overturned in court. transport for london refused to renew its licence when it ran out last september, saying the firm was not "fit

and proper" to operate due to safety concerns. the company has now been granted a permit for the next 15 months while it continues to try to meet certain conditions. the duke of cambridge has met the israeli prime minister, benjamin netanyahu, on the third day of his tour of the middle east. the prince, who's the first member of the royal family to visit israel and the palestinian territories, visited the world holocaust remembrance centre in jerusalem. the firefighter in charge during the initial response to the grenfell tower fire has broken down in tears at the public inquiry as footage of the blaze was shown. michael dowden said he didn't have the resources to carry out an evacuation of the building and that firefighters were unable to get water to the top of the building. our special correspondent lucy manning's report contains images of the tower on fire. just minutes after the fire started, michael dowden walked into grenfell tower with his fire crew. in the white helmet, with "incident commander" on his back, he was in charge for the first hour

of the blaze. today he was shown video of the fire spreading up and across the building, with debris falling. he was asked, when the tower was alight after half an hour, whether he thought about abandoning the stay put policy and telling the residents to evacuate. for me, at that moment in time, to facilitate and change the stay put policy to a full evacuation was impossible. i didn't have the resource at that time. we are looking at 20 floors above the fire floor, with just six fire engines in attendance. 0ne central staircase. something i've never experienced as an incident commander before. very, very much out of my comfort zone. ijust don't know how that could have been done with the resources we had. as he had watched pictures of the tower burning, mr dowden wiped tears from his eyes and asked for a break.

are you 0k? can i take a break, please? yes, yes, of course. it won't have escaped anyone's attention, i'm sure, that mr dowden is finding giving this part of his evidence very difficult. the firefighter admitted as he requested more fire engines, six, then eight, then ten in a matter of minutes, he shouldn't have still been in charge. senior officers would normally have taken over. is it normal procedure for a watch manager to be in charge of a fire where there are more than six pumps? no, it's not normal. it was a fire, he said, that was developing rapidly. he was consumed by what was happening and wasn't aware of everything going on inside. but he said, i was doing my best to carry out my duties. lucy manning, bbc news. as temperatures are continuing to rise, many are basking in the sun. the met office, though, has issued a heat health alert. and a fire has devastated

parts of saddleworth moor in the north west of england. danny savage is in blackpool tonight. it looks gorgeous there, doesn't it? it looks gorgeous there, doesn't it? it is lovely and when it comes to this extreme of the british weather i suppose this is how we'd like to enjoy it, on the beat woking up the evening sunshine. the further west you went, the warm it got. —— the warmer it got. there have been some problems as the weather has got hotter and hotter. across virtually all of the uk the heatwave continues. and quite understandably many people are making the most of the glorious weather. yeah, we were looking for a breakfrom weather. yeah, we were looking for a break from the heatwave coming here and it's the same. it was 102 degrees when we left california, so this isn't so bad. but as is so

often the case, there have been tragic accidents as people try and cool off. last night three children got into difficulty at westport lake in stoke—on—trent. two boys got out of the water but a third, named by police as ryan evans, is still missing. further north a large wildfire on the pennine moors has left a pall of smoke hanging over large parts of greater manchester. it's been burning since sunday and could be seen for miles. people living nearby are being culled to keep their windows closed, as firefighters try and contain it —— people living nearby are being told. terrible, 20, 30 foot flames. in dorset they even got the gritters out to stop roads from melting as surface temperatures soar. but at the seaside resorts like here in blackpool, it couldn't be better and

for the next few days if you want the hottest weather, west is best, as was proved earlier with hardened airport near chester and porthmadog reaching nearly 31 celsius. the hottest day of the year so far. danny savage, bbc news. football, and argentina, one of the tournament favourites, could be eliminated from the world cup tonight. lionel messi's team must beat nigeria, to be guaranteed a place in the next round. richard conway is outside the krestovsky stadium in st petersburg for us, an exciting night ahead. a big night ahead, for argentina and that man, lionel messi. at the age of 31, he could be looking at his final world cup. the fans arriving here, kick—off is an hour away, they wa nt here, kick—off is an hour away, they want the world cup to go on beyond this point, they don't want it to end here but they need to win tonight against nigeria and they have to hope that the other group

game between iceland and croatia goes their way. we saw france and denmark playing a goalless draw, one point each for them and they both qualify for the last 16. peru, their first world cup in 36 years, winning against australia, so they go home happy despite not qualifying. but tonight the focus is on this stadium, an argentina and lionel messi, whether he can get them into the knockout round. thank you for joining us. lets hope the game goes more smoothly than that satellite link. sorry about that. time for a look at the weather. here's ben rich. very little change over the next few days, plenty more warmth and sunshine. more scenes like this from this weather watcher in nottinghamshire. not the first time we've said this, the highest temperature of the year so far according to the met office, close to 31 degrees on the west wales

coast. going into tomorrow, the heat pushes further north, northern ireland and scotland and we may have temperatures close to 30 degrees. this evening and tonight, clear skies for most people, extra cloud in from the north sea towards eastern scotland and the east of england. in eastern areas tomorrow, misty and murky, don't be surprised but don't worry because the cloud is going to burn back to the coast, out to see through the day. for most it will be fine and dry, long spells of sunshine but some areas of cloud may come onto the east car beaches at times. temperatures here a little bit less. some places into the high 20s, close to 30. for the east of the country, the east coast especially, some areas of cloud coming and going over the next few days to the weekend but temperatures will be suppressed as well.

elsewhere, the next couple of days bringing long spells of sunshine. some high temperatures, 28, 29, possibly 30. the sunshine will be strong with high ultraviolet levels. if you're looking for a change, and some people are, the weekend brings a set of thunderstorms from the south. uncertainty about the timing. fine weather before that but some changes on the horizon. a reminder of our top story... a british plumber who was also an al qaida bomb maker is convicted of plotting a terror attack in westminster. hello. this is bbc news with shaun ley. rescuers in thailand have stepped up their search for a group of children believed to have been trapped in a flooded cave in the north of the country since saturday. 12 children aged between 11 and 16,

together with their football coach, were exploring inside the cave's narrow tunnels when a section near the main entrance was flooded. the underground network in chiang rai province is a popular tourist attraction in thailand, attracting thousands of visitors every year. the bbc‘sjonathan head sent this update from the cave complex in chiang rai province. this is where you come into the cave complex. as you can see, these are the bikes that the boys left when they went in on saturday afternoon. they've been down there now for three days. obviously, there is real concern about their state of health, although it's reasonably warm, possibly not too cool inside. the assumption is that they got cut off by rising floodwaters and that they are still alive. the trouble is this is a complex that goes back for ten kilometres. the navy divers simply couldn't get through the narrow passages, and they are hoping that some of the volunteers who have got more caving experience may have more success.

we've seen a lot of oxygen tanks being brought up here. they've also got pumps over on the other side, which we expect them to start using. it's not clear where they are going to pump the water from, but clearly they are trying to get those water levels down, although with this constant rain it's not clear what success they'll have. but this is very, very worrying for the relatives, who have been coming up here and praying at makeshift shrines they've put up in the forest for a good result, for some kind of good news. they still haven't had it, and they've still got no idea what state those boys are in, or in which part of the caves they may be located. today has been the hottest day of the year, after temperatures reached over 30 celsius in north wales. the met office has issued a yellow weather warning because of the high temperatures hitting much of the country. but what dangers does

the heat pose to health? joining me now are robert henderson from age uk and thomas waites from public health england. welcome to you both. thomas, you as an organisation have a responsibility for ensuring we look after ourselves. what is the advice in these weather conditions for the general population? much of what we can all do to keep ourselves well is common sense, making sure you are well hydrated, keeping water with you, drinking lots of water during the day but also keeping yourself cool in a variety of ways and keeping your home cool. a lot of people will go at work the morning and leave the curtains open, and it eats up all day, so shutting the curtains during the day, opening the window at night, important things. interesting, because you go to a lot of countries which are used in hot

weather and people routinely shut blinds and curtains, drawdown blackout materials or some kind to keep the temperature cool. it's not something we are used to doing. places people go on holiday to, we are used to seeing shutters on the outside, tiles on the floor, things which are designed for keeping places cool, but only about 12 weeks ago it was —10 in some parts of the country and now it is almost a0 degrees hotter will stop it in extreme range of temperatures that are houses have to be adapted to and, when we can't have those shutters, doing the best things we can, like shutting the curtains, if the next next thing. let's talk about older people. i have relatives who i know don't necessarily drink enough fluid at the best of times, and trying to convince people to drink fluids when the temperature is going up significantly is a bit of a challenge, isn't it? absolutely, and it's very important. when it's hot,

we are sweating more and losing more salts and fluids, so we need to make sure that older people continue to eat and drink normally, but make sure they are perhaps eating cold foods, like salad and fruits, which add more water in them, and make sure family and friends keep an eye on older people in hot weather. older people should be able to enjoy hot weather but we should also be aware that some older people can be more vulnerable when temperatures are particularly high. and it's not just the elderly. absolutely, lots of people can be a risk, older people, those with long—term conditions, heart problems, kidney problems, lung problems, and very young children. it stems from what we do to try and keep. we shan‘t extra blood towards the skin, so you radiate heat out. it's why people look red. sweating means you lose a lot of fluid and salt, and pushing blood to the skin to radiate heat

output stream on the heart. in terms of practical measures, you've talked about keeping yourself well hydrated. what about covering up? there is a great desire for people, when they don't see weather like this normally, to strip off and go, great, the sun is out, get your t—shirt and shorts on, and people like me have to be a bit careful, because we don't realise how intense the sun can be when it hits your head. what should people think about? it's notjust a heatwave, we are about? it's notjust a heatwave, we a re close about? it's notjust a heatwave, we are close to the longest days when the sun is strongest. so staying at the sun is strongest. so staying at the sun is strongest. so staying at the sun between 11am and 3pm is very important. that doesn't sound like fun! everything in moderation. just taking careful to a sun hat is an obvious thing. wearing sunglasses protect your eyes from uv. wearing a t—shirt is important for young children, who have somebody to dress them, and everybody needs to be

wearing suncream in these temperatures. it's an important way to protect yourself notjust temperatures. it's an important way to protect yourself not just against sunburn but longer term problems like skin cancer. for those who might think we are being a bit miserable talking about this, without being too miserable, can you talk about what the stats are for the risk to elderly people's health? we talk about people dying during severe winter weather, failing to adjust the temperatures of their heating, for examples, failing to keep sufficient body warmth. 0n the other side of the equation, when it is like this, quite risk are elderly people? how many people die? we don't have the figures, but we need to take hot weather as seriously as very cold weather for older people. we need to make sure they are following common—sense practicality is that tom touched on, closing the blinds, wearing loose fitting clothing and that kind of thing, but there is lots we can do practically in communities to help older people.

if there was a blizzard, you'd probably go around and check on your neighbour. if there is a heatwave, you should check on your neighbour as well, and make sure they've got enough ice, a flannel, practical things like that. they are at risk so we things like that. they are at risk so we need to look after them. —— a fan. if older people are listening and we might be making them nervous about going out, what would you say about going out, what would you say about them preparing themselves a simple things they can think about? as we've said, try and stay out of the sun between 11am at 3pm, enjoyed the sun between 11am at 3pm, enjoyed the sun between 11am at 3pm, enjoyed the sun when you are out there, make sure you are covered in loose layers, and enjoyed it and make sure that you are drinking the same but —— eating the same but drinking a bit more. i think if it stays like this we should be able to loosen our ties! hopefully all of that advice will be taken on board. mps have warned that britain will lose its influence with the us and other nato allies unless it increases defence spending by tens

of billions of pounds a year. the commons defence committee is calling for a boost similar to that which has been promised to the nhs. it comes at a time of heightened tension between the ministry of defence and downing street about budgets. dr catarina thomson is a senior lecturer in strategy and security at the university of exeter. thank you forjoining us. let's deal with the factual stuff first, if we may. what proportion of our budget in terms of public spending are we devoting to defence? the government says it is meeting 2%. what does that mean? it means that 296 says it is meeting 2%. what does that mean? it means that 2% of gdp is going to defence, which means we are in compliance with nato norms. what has been proposed today is an increase to 3% of gdp. in terms of where this money is being spent, at the same time we are hearing that our armed forces, in terms of the

number of men and women employed, have never been smaller, certainly not smaller since the napoleonic wars, but that sounds odd if you are talking about is meeting the nato target. sorry, i didn't hear the last bit. often told that we are beating the nato target but at the same time many military chiefs grumble that we have got the smallest armed forces since the napoleonic wars. did you hear? yes, ican hear napoleonic wars. did you hear? yes, i can hear you now. i think the point is that having a strong defence isn't just about point is that having a strong defence isn'tjust about protecting the nation. it's also about power projection. the point has been made by other players at this key time, at this time in history, as brexit is occurring and we leave the eu, we need to decide what kind of international player we are going to be. if you look at the 2015 strategic defence and security review, it is very ambitious in scope, and several actors have been proposing today in order to

adequately fulfil those statements that have been set forward. we need an increase in funding. a former chief of general staff was saying in his contribution today that he thinks we've been deluding ourselves that we are spending sufficient to justify our self—confidence about our place in the world. in other words, our new military capabilities, the ones that we aspire to have, can't be afforded on the amount of money we are devoting to defence at the moment. the amount of money we are devoting to defence at the momentlj the amount of money we are devoting to defence at the moment. i think he is correct to point out that there is correct to point out that there isa gap is correct to point out that there is a gap between the kind of power projection we seek to have and that we say we have and the kind of resources we've had. this is in the context of cuts to that have occurred under these times of austerity recently. and it's not just, as i said... please continue. asi

just, as i said... please continue. as i said, it's notjust about protecting the nation but power projection and the signals we send out to key allies at this point in time, in which we are trying to say we are open for business, we are leaving the eu but we want to remain a key international player. you have researched public attitudes to increasing defence funding. what is the public view? is it something people want invest more in? one shocking piece of information i found in the survey, in which we looked at security views of the public and security experts, was that again, after years of austerity, only 12% of the uk population thinks we should cut defence spending. overall, only 38% of the public thinks we should increase defence spending, but if you split it between people who voted for brexit and people who went to remain, a majority of those who voted brexit think we should increase defence spending. across the board, a majority of the

population in the uk thinks the uk needs a strong military in order to be efficient in international relations, including three quarters of those who voted leave. so there isa of those who voted leave. so there is a strong division. yes. catarina thomson, thank you for being with us on bbc news. the us supreme court has upheld president trump's travel ban targeting several muslim—majority countries. the five to four ruling by the conservative majority gives president trump a big victory and — for the time being — ends a fight in the lower courts over whether the policy represented an unlawful ban on muslims. in the last hour, the president praised the supreme court's decision. the supreme court ruling just coming out, a tremendous success and tremendous victory for the american people and for our constitution. this is a great victory for our constitution. we have to be tough and we have to be safe and we have to be secure. at a

and we have to be safe and we have to be secure. ata minimum, we and we have to be safe and we have to be secure. at a minimum, we have to be secure. at a minimum, we have to make sure that we've let people coming into the country, we know who is coming in, we know where they are coming from. —— we have to make sure that we vet people. we have to know who is coming here. the ruling shows that the attacks from the media and democrat politicians are wrong, and what we are looking for as republicans i can tell you is strong voters, no crime. what the democrats at is open borders, which will bring tremendous crime, it will
