our correspondent ben ando reports. friends, class mates, mourners. three, two, one... grieving together, an improvised memorial for a tragedy as shocking as it was unexpected to mark the deaths of three teenagers struck by a speeding car in hayes in middlesex yesterday evening. the teenage boys have not been formally identified, but named locally as george, harry and josh. two were 16, the other 17. earlier their families had visited the bus stop where the boys had lost their lives. jake webb was one of the first on the scene immediately after it happened. i could see the incident in front of me. i had called them at that point. there was a bus driver in front of us. he came over and said, "there's someone dead in the road". at that point i relayed that to 999. within five minutes, an ambulance arrived. friends of the boys say

they were walking on the pavement in this direction, going to a party, when a car struck the pavement about here. seconds later, it hit them. the car, a black audi, smashed into a lamp post before coming to a halt in the road. this image shows the force of the impact. eyewitnesses said afterwards a man who had been in the car was attacked on a garage forecourt nearby. some locals say speeding cars here are nothing new. it's a 60mph road. cars and vehicles drive up and down here sometimes like it is a speed trap. this road is busy 24/7. if i'm totally honest, i'm surprised there has not been more accidents along it. police believe two men were in the crashed car. and with many people heading to the same party, they want any witnesses to contact them. two the victims have been named, harry price and george wilkinson. --

two of the victims. more on that as we get it. all current rape and serious sexual assault cases in england and wales are to be reviewed, following the collapse of several recent trials. the director of public prosecutions alison saunders said it was "a matter of urgency" to make sure evidence has been properly disclosed. but the government's chief legal adviser says there's no evidence of "widespread malpractice or dishonesty" in the prosecution system. clive coleman reports. disclosure of evidence in some recent highly publicised rape cases has gone badly wrong. but how widespread is the problem? in december liam allan's trial collapsed. when it emerged evidence

on a computer disk which police had examined showed messages from the alleged victim pestering him for casual sex. and the number of prosecutions in england and wales that collapsed because of a failure by police or prosecutors to disclose evidence has increased by 70% in the last two years. now the director of public prosecutions, alison saunders, has ordered an urgent review of all rape and serious sexual assault cases, and conceded it's likely a number will be dropped. one of the major problems is the amount of evidence on digital devices, such as mobile phones and social media. it's very apparent that in some cases mistakes have been made that simply shouldn't have been. it is important that when you look at that kind of case that the prosecutors and investigators look at social media traffic, look at text messages that have passed between the two individuals, because they can put what's happened in a very significant, different light. a national disclosure improvement plan has been published. it includes a review of disclosure training, developing a group of specialists in every police force, and all multimedia evidence to be provided to the defence digitally. yesterday, here, a people—trafficking case —

not a rape or sexual assault trial — collapsed because prosecutors failed to disclose critical evidence to the defence. thejudge has demanded an urgent explanation in a case made even more shocking by the fact that one of the young female defendants was held in prison for 13 months, during which time she gave birth. this problem is systemic and endemic throughout the criminaljustice system. it's been known about for many years and it's a result of chronic underfunding of police, the prosecution service and particularly defence lawyers who have suffered years of cuts to legal aid. if public confidence in our fair trial system is to be maintained, fixing disclosure is now the criminal justice system's biggest challenge. clive coleman, bbc news. regarding the deaths of the age boys

in west london, a man aged 28 has been arrested. two of the victims have been named locally as harry rice and george wilkinson. a bomb in the afghan capital kabul has left 95 people dead and more than 150 injured. the taliban say they carried out the attack. an emergency vehicle, packed with explosives, was blown up at a checkpoint. from kabul, zia shahreyar reports. an ambulance packed with explosives driven into crowds on their way to work. the force of the blast shook the windows of buildings at least a mile away. some low rise structures collapse. a plume of smoke visible across the city.

the attacker had driven his vehicle past the police checkpoint, claiming to have a patient inside. when guards at a second checkpoint became suspicious, he detonated the bomb. translation: i was in an armoured plated vehicle when suddenly there was an explosion. i was in the back seat, my driver was blown out on to the ground and injured. the area of the attack is home to foreign embassies and the city's police headquarters. the road had been closed to public transport. the taliban claimed responsibility. this is their second deadly assault on the city in the space of a week. 20 people were killed in an attack on the intercontinental hotel last week. this evening, work was continuing to clear the scene of the latest bombing. this is a very secure area and security is very tight here usually and the question will be how they got through this far. the afghan military, backed by us air power, has intensified its campaign to drive out the taliban from its rural strongholds. but, as today's strike proves,

they're still able to mount deadly attacks against civilian targets in the heart of the country's major cities. and we'll find out how this story, and many others, are covered in tomorrow's front pages at 1030 and 1130 this evening in the papers. our guestsjoining me tonight are nigel nelson, who's the political editor of the sunday mirror and sunday people, and the broadcaster and journalist, penny smith. the release of the black cab rapist, john worboys, from prison has been put on temporary hold, following a legal challenge by two of his victims. the 60—year—old was jailed for a minimum of eight years in 2009, for the rape and sexual assault of women across london. lawyers representing the women were granted a stay on his release, after making an urgent application to the high court. the prime minister of ireland has told the bbc he will campaign for the country's near total ban

on abortion to be liberalised. leo varadkar had previously said the laws were "too restrictive". a referendum will take place this summer on whether to repeal a constitutional amendment that effectively bans terminations. the entire us gymnastics board is to resign because of its handling of the sex abuse scandal involving the former team doctor, larry nassar. the country's olympic committee had threatened to strip the organisation of its powers if the directors failed to stand down. nassar has been given a prison sentence of up to 175 years for abusing more than 150 female gymnasts. peter bowes reports. as larry nassar begins to what amounts to a life sentence, the fallout from the abuse scandal has been swift and decisive. the entire board of usa gymnastics has gone and there have been other resignations too. mark hollis was the athletic director at michigan state

university when nassar worked there. he and another official have decided to quit. it's been an absolute honour to guide the athletic department for the last decade. that being said, today i'm announcing my retirement. i'm not running away from anything, i'm running towards something. comfort, compassion and understanding for the survivors in our community. togetherness, time and love for my family. there have been reports that michigan state university and usa gymnastics knew of the abuse claims but failed to take action. they've both denied there was a cover—up. with several investigations into abuse in us sport now under way, the recriminations are onlyjust beginning. peter bowes, bbc news. let's get more on this story with our washington

correspondent david willis. this story rumbles on and we could see more resignations, as well. indeed. what the heck is going on at michigan state university, that was the opening gambit today of the michigan attorney, the state attorney, who is conducting what he says will be a thorough inquiry into this abuse situation. he said there will be a bright light but at every corner of the university and no individual or department is off—limits. he has appointed a retired county prosecutor to take charge of this investigation. basically what officials want to know, how larry nassar was able to get away with this abuse of young girls and young women for so long, nearly 20 years, and whether anybody at the university was knowledgeable

about what he was doing and perhaps even attempting to cover up what he was doing. people have been protesting at the university? because of how badly it has been handled. yes, there has. last night there was a protest and there may be more to come in the future. meanwhile, michigan state university has received about 130 different lawsuits from people who were victims of larry nassar and it has attempted to get those lawsuits dismissed on technical terms. but the michigan attorney general was very critical of the university today, he said he won't be taking any advice from them and he will be focusing this very bright light on the activities of everybody from the top of the university structure to

the bottom. david, thanks for joining us. one of the largest digital currency exchanges injapan has said that it's network has been hacked. coincheck has suspended all deposits and withdrawals for all crypto—currencies except bitcoin whilst it assesses it's losses. if the theft is confirmed it could be one of the biggest digital currency theft recorded. if you're as confused by digial currency as i am hopefully our next guest marc warne ceo of the bitcoin trading company bittylicious can makes sense of it all. he joins us from york via webcam. what is a crypto currency? it's a very good question. crypto currency isa very good question. crypto currency is a new way of thinking about money, a way of putting control back into the hands of the consumer, and each person can hold a certain amount of crypto currency, bitcoin,

for instance, and they have control of it, and without involving a bank they can send what they have directly to other people. how do you create this money, this currency? is it created in the ether? pretty much. every ten minutes these currencies are created. this is a way of injecting money into the system and incentivising the people who are facing security for the it is these people who make sure that money can only be sent once and there is no way to do for the network and that is how it gets injected into the system. —— defraud the network. this hack, business

regulation for crypto currency at the moment? —— there is no regulation. in most countries you are right, but injapan, this is one of the biggest of them, coincheck, and this is a very big hack, potentially, but it doesn't seem to be impacting the price for a much what you might be losing money which isa what you might be losing money which is a bit ofa what you might be losing money which is a bit of a problem. the prize itself and the general integrity of crypto currencies is fine and i can see right now the price of the crypto currency involved has gone up 2296 crypto currency involved has gone up 22% surprisingly. it is not similar to previous figures before when it was a big problem for the whole crypto currency network as a whole, it is something people realise doesn't affect most other people that aren't involved directly. how risky is victor currency investment? —— crypto currency. it is risky is victor currency investment? -- crypto currency. it is being discussed at davos. what security do

you have? you have to think much more about security, no doubt, think of it as if you are carrying cash, where you are more susceptible to having people steal your cash so you have got to think about your own security. if i had a small amount on my mobile phone, and in my pocket, maybe £50, but if you are storing a lot, you have got to think about, but there are hardware solutions which will protect you very well, but the problem is people were storing their money with an exchange and it is unsafe to do this if you are storing a significant amount. sadly people are still doing this, so sadly people are still doing this, so there is education that needs to be done. there is no oversight, governments are out of this? hence many people who like to keep below the radar like crypto currency. north korea is a big into crypto

currency. would you advise people to go down this road? people should investigate this crypto currency, i think it is the future of money, but of course, people, will hughes crypto currency, and that proves it works —— will use crypto currency. you don't have to worry about banks and in paris people, and yes, bad people will use it, but so will good people. —— and it empowers people. thanks forjoining us. the headlines on bbc news: three teenage boys have been killed when they were hit by a car in west london. a man has been arrested. the attorney general has acknowledged that "very serious mistakes", over the disclosure of evidence by prosecutors, have led to the collapse of recent trials in england and wales. at least 95 people have been killed

and more than 150 wounded, in one of the deadliest attacks on the afghan capital, kabul, in recent months. sport now and a full round up from the bbc sport centre. a late harry kane equaliser spared tottenham's blushes in the fa cup fourth round. they will need a replay to get past league two newport county after a 1—1 draw. joe lynskey has more it's the competition that throws up the culture clashes, rodney parade feels a long way from wembley stadium, this is where football is at its purest. when you take on the big teams, it's risk and reward, the league 2 side were getting on the front foot. they use this pitch for rugby some weekends, frank nouble's finish was closer to a conversion, but here were signs the surface could be a leveller, even spurs's best struggled with it.

the premier league side were given a warning. soon, the magic moment was coming. commentator: is in for newport county! a moment for south wales to sing for, this had the makings of a most remarkable upset. it looked like spurs were struggling to find their rhythm, but they do have one player who always perseveres. commentator: harry kane has a tap in! spurs were in a hurry to get the game won, but this chance for dele alli was the closest they came. a draw means newport can celebrate a famous day, a fourth—round replay at wembley to come with the team from rodney parade getting their day in the sun. west ham were the highest profile casualty in today's fourth round ties. they lost 2—0 to league one wigan athletic. will grigg scored both goals. you couldn't have called as a premier league side because we didn't have enough premier league

players in the starting line—up, and it was a difficult encounter for us and we had many young players who had the chance to impress me, but not many of them impressed me, and i was disappointed with the senior players who did not help them. all in alla players who did not help them. all in all a disappointing performance and result, but we think we have biggerfish to fry and result, but we think we have bigger fish to fry this time. there is one other game ongoing — and that's an all premier league tie between liverpool and west brom. firminho put liverpool ahead. west brom drew level within ten minutes throuthay rodriguez. he scored a second just minutes later. and then craig dawson's header was ruled out by the video assistant referee. gareth barry in an offside position when the goal was struck. then the var awarded liverpool a penalty shortly after, all of this happened inside 26 minutes! except roberto firmino missed it! a full list of results can be found

on the bbc sport website. in the scottish premiership, celtic moved 1a points clear at the top after beating hibs1—0 aberdeen climbed above rangers — who play tomorrow. the dons beat kilmarnock 3—1 with two goals from scott mckenna and another from niall mcginn who ran round three—quarters the length of the pitch to score aberdeen's third. a dream come true is how caroline wozniacki described becoming a grand slam champion. the danish second seed defeated simona halep in three sets to win the australian open. it took her 43 attempts to win a slam — and her reward isn't only that shiny trophy. she'll also become the world number one. she was playing really well and i was thinking it looks like it may not be my day but i was never really nervous. i was just going to go out there and give it my all and swing for it and play aggressively. i

think i played well. they could have gone either way but i'm happier when my way. rory mcilroy will tee off in the final group tomorrow at the dubai desert classic — chasing a first victory in 17 months the four—time major winner is just a shot behind leader haotong li on 19 under par. mcilroy shot a third round 68 — aided by two birdies in the last three holes. that is all the sports for now. homes and businesses in paris are on high alert as the river seine threatens to overflow its banks. weeks of rain have pushed the water level up and its thought the river will peak six metres above normal. museums including the louvre have been shut. in smaller towns along the seine, people are having to use boats to get around flooded streets. in the last hour i spoke to a lecture in the city and he'd tell me how the river is looking this evening. —— he told me. how the river is looking this

evening. -- he told me. it's high but it is not causing any panic and it is saturday night and the bars and cafes are open and we have not run out of wine and coffee and we are getting on with things. laughter wine or coffee, i love it, but what are the parisians saying about it? to be honest, i've spoken to some, and the people i've spoken today who i have been lecturing at the school, there hasn't been great concern. they are seeing this rise and there is information on the paris government website. that is showing that there is a risk of some flooding, predominantly locally to the sellers in some of the buildings which are now used for parking and people have moved stuff out. but frankly it is the weekend and there is nothing we can do. there is a feeling there is nothing that can be

done, so why worry about it and let's get on with it. you are quite close to the river, can we have a look? just so people can get their bearings, that is notre dame, and we are... that should be able to get under that quite comfortably, but it can't, as you can see from the size of the people that are walking over the top. it is extremely high. my understanding is that it will continue going up a bit until tomorrow and then it will start going down again. fortunately it has not been raining today. it is the water flowing through. are you worried? do you have plans in place if the banks burst? no. i live in brittany where it is perpetually wet a nyway brittany where it is perpetually wet anyway so we are not that concerned. i'm getting on the train tomorrow

and the trains will be running and if not, it won't be because of this. i wasn't planning a walk down the river today, and your viewers may note... they may know there's walkway that goes down the side of the river and that is the walkway, it doesn't exist all the way along, so for most people is not having much effect really, other than to have a look, just as a spectacle, but apart from that, most people are quite relaxed about things at the moment. elderly survivors have gathered in auschwitz in poland to mark holocaust memorial day. six millionjews, and millions

of others were murdered in concentration camps by the nazis during the second world war. evening prayers have been said at the former auschwitz—birkenau concentration camp, and tributes paid at the monument to the victims at the site. in the czech republic, a tightly fought presidential election has been won by the incumbent. president milosh zeman is known for his strident anti—immigration views and for his opposition to eu sanctions against russia. he won with just over 51% of the vote, defeating the pro eu academic, jiri drahos. one of the world's richest men held for two months by the saudi authorities in an anti—corruption drive, has been freed. prince alwaleed bin talal was one of 200 princes, politicians and wealthy businessmen detained in a crackdown. they were held at a luxury hotel in riyadh. it's believed a financial settlement was agreed in return for the prince's release. a mural by the world famous graffiti artist banksy has appeared in hull. hundreds of people have been turning up to see it on a disused bridge in the city. the artist has appeared to confirm

that it his work on social media. not everybody is happy about it — one city councillor said today, it's vandalism and should be rubbed off. matthew bone has the story. the bankside area of hull is no stranger to graffiti, but this latest addition is a little different. the artwork certainly looks like a banksy, and the artist seemed to confirm its identity on social media. it has caused a lot of interest. this is a quiet, old industrial part of hull, but ever since rumours of the banksy appeared last night, a steady stream of people have come here today to check it out for themselves. it's really good. fantastic. i like the way that the writing on that is like on a chalkboard or a school. i like his shoes. he has got a nice pair of shoes on. you've got to wear a nice pair of shoes. of the hundreds of people who have come along to see it, gavin is more excited than most. a lifelong banksy fan,

he works just around the corner. for me, the culture i grew up with, it is a dream come true. what does the mural mean? it depends who you ask. the bridge is raised. it is the drawbridge. for me, hundreds of years ago, we never let the king into hull. a sort of defiance, a sort of challenge. it could have been to do with us voting out, for brexit. it's all about pulling up the drawbridge again. not everyone is happy to see the graffiti appear. one conservative councillor has an idea of what to do. record by whatever means we can banksy‘s contribution to that piece of work. then clean it off. it is graffiti. all graffiti is damage. if banksy wants to create real art, and i'm sure he does, then perhaps it might be a good idea

to buy some canvas. the graffiti has already been graffitied, with some green spray just nicking the toe of the mural. this afternoon, new fencing was put up to prevent people from getting up close. six months ago, tallulah the tortoise went missing. this week, she was found just over 300 metres from where she disappeared. let's find out what happened to her.
