remains tight, both in paris and right across france, head of the first round of residential voting on sunday. but those fatal shots fired by karim have already cast a shadow over the ballot. in this election, not everyone fighting for influence isa not everyone fighting for influence is a politician. last night, a lone attacker with an often matic weapon brought chaos to the capital's well guarded heart. his target, french police. curling a country on the cusp of an election after two years on high alert. this mobile phone footage shows the moment he killed a policeman and injured two others before being shot dead on france's most famous street. the policeman he killed was identified today, and dead for doing

his duty, the interior minister said. the group calling itself islamic state has claimed responsibility, the gunmen named as 39 the rd frenchman karim cheurfi —— karim cheurfi, who had already spent yea rs karim cheurfi, who had already spent years in prison for attacking police. officers today searched his family house east of paris, three of those living there are now being questioned. neighbours told us they did not see the family very often, one man said he read about the attack in this morning's paper and discovered that karim cheurfi had been living on his state. melo today another house and neighbourhood rebranded as part of the story of france's terrorist attacks. but thousands of people from ordinary areas listed as potential threats, security services here are stretched to breaking point. this election was a lwa ys to breaking point. this election was always seen as a target for terrorism, 50,000 security forces have been brought into security vote. the leading candidates have

promised thousands more police posts if they are elected, and when it comes to being tough on terrorism, it is sometimes hard to tell them apart. tries melo we want to take back control of our borders. translation: i will raise the level of protection on our borders by renegotiating the treaty. translation: preachers of hatred must be expelled and islamist mosques closed. translation: note a man in any mosque will be able to preach against the values of the republic. the liberal newcomer said their duty was the key. translation: at heart it is our democracy that is being targeted, our unity. i say don't give in to fear, or division oi’ don't give in to fear, or division or intimidation. france's locked in a debate about how to stop attacks like this, even harder perhaps to stop them influencing its democratic

transition of power. our correspondence in paris, christian fraser spoke to a counsellor for left front, one of the millions of people are likely to vote for no one in sunday's election. melo my natural candidate would be john in sunday's election. melo my natural candidate would bejohn luke melling john, because he is from the same political side. i have too many disagreements with him. for example on immigration. i think that today... goes back years to tough? yes. i am for the free installation... i am yes. i am for the free installation... iam not yes. i am for the free installation... i am not for his controls on frontiers. i think that france has a responsibility in what happens today in the integration of people from africa, north africa...

goes like you would have an open door policy? maybe you were collared open door, but you cannot prevent people from emigrating. it is impossible. the obstacles that are put ina impossible. the obstacles that are put in a way might be counter—productive? put in a way might be counter— productive ?|j put in a way might be counter-productive? i think we have about everybody, notjust give papers to people that work, but to everybody. joining me now is the anglo—french journalist and broadcaster. badge driven coming in. how are those poles looking? very tight. all polling and campaigning stops tonight. so that the french people can have time to reflect, read up and to think about their vote. uppermost in their minds will be security issues and the future of france. the polls, the four leading

candidates is that of the two front ones, are emmanuel macron, marine le pen, you have francois fillon, and then you have surprised a jean—luc melenchon, but it seems to be tightening as we had the first three i mentioned within about 4% of each other. it is the most unpredictable and wide open presidential election in modern history. many people voted for and none of the above. why? we'll see what the french people decide, that is what the pollsters think, and there are people who says they will abstain will do what they call in french... i think a lot of people who are disillusioned in france and indeed in other countries with politicians, the political class, and that is why a candidate

like emmanuel macron is saying it is no longer do think of right and left, we need some of the policies on one side and some of the other, he were to become president at 39 yea rs old he were to become president at 39 years old it would be remarkable. other people are saying that the latest shooting in paris and killing ofa latest shooting in paris and killing of a police officer, serious wounding two others and of a german tourist are really going to play to the fears of some people, to use the marine le pen senators plan to close the borders, stop immigration, not just illegal in the but chuck out anybody who is suspected by intelligence services are is foreign. we were ultimately see who goes through to the two candidates, who get the most votes, we don't think anyone will get 50%, so who are the two people who are going to go forward and you then will be within a very short breadth of the palace itself on the 7th of may.

what about turnout? what are you expecting? you say people are disillusioned, do you expect...? expecting? you say people are disillusioned, do you expect. . . ? and thatis disillusioned, do you expect. . . ? and that is also an unknown. how correct at the polls? who will go thrower but how many people abstain? it was 33% a few weeks ago, it looks like people have been making their minds up people have been making their minds up in the last week. we think it might be 23% abstention, but it is a very important election notjust for france but for the united kingdom, it will have an effect on the rest of the eu. it is crucial for france and we will see who versus who i will find that out on 7pm london time this sunday. police in germany have arrested a man accused of bombing the boss of the german football tea m bombing the boss of the german football team dortmund last week.

one player was injured on the bus was on its way to the stadium. the suspect may have been carrying out a complex financial scam. the bombing was potentially deadly, shattering the windows of the coach, it was only a matter of luck that no one was killed. police initially thought the attack on the team bus was an act of politically motivated terror, but now prosecutors say the attacker was driven by greed, not ideology. a 28—year—old man who stayed in the same hotel as the players is accused of bombing the team in order to force the club's share price down, prosecutors say his aim was to make a huge profit on the stock market. translation: retraced the accused by noticeable option dealings, we now know that the accused but the different derivatives of the dortmund stock. with all these

directors he speculated on falling stock prices, but the main part of these finance products himself on april 11, so the day of the attack. the team has expressed relief that the perpetrator appears to have been caught, but there is also widespread disgust in germany that summer may have been prepared to kill in order to make money from shares. the team is looking for to the next match on sunday but some players have not yet fully recovered. translation: sunday but some players have not yet fully recovered. translatiosz sunday but some players have not yet fully recovered. translation: is a success fully recovered. translation: is a success would give us a boost, i can speakfor success would give us a boost, i can speak for myself. i think that i am able and at the moment i don't see why i personally cannot, with all the emotion involved cannot coach this game. the bombing shocked germany, particularly because it was not clear who the attack and why. officials remain cautious, saying in

the perpetrators could be islamist extremists or criminals with a com pletely extremists or criminals with a completely different motivation. now it seems that caution has paid off. us military officials say a close associate of the group that calls itself islamic state. us military officials say a close associate of the leader of the group which calls itself islamic state, has been killed in a commando raid abdurakhmon uzbeki was reportedly killed during the ground assault near mayadin in syria. our correspondent in washington, gary o'donoghue, has more details. the attack took place on the 6th of april. i think the reason foreign the gap is that they try to gather as much intelligence as they could in order to get the man they thought they had got. that was probably the reason for the delay. it was a ground operation, in other words the us spent a lot of time hitting

people in syria and iraq, individuals through drone strikes and hellfire missiles fired from drones, much more rare is using commandos on the ground. and we'll have more later. as hacking becomes a bigger and bigger problem , signs emerge of how young the hackers are. in britain the average age is 17. the bodies of the dead still inside. i never thought they would go through with it. some places have already had nearly

as much rain as they normally expect in an entire year. for millions of americans, the death of richard nixon has meant conflicting emotions, a national day of mourning next wednesday, sitting somehow uneasily with the abiding memories of the shame of watergate. liftoff of the shame of watergate. liftoff of the shame of watergate. liftoff of the spaceship discovery with the hubble space telescope, our window on the universe. the top story. the man who shot dead a policeman in paris on thursday , karim sure—fee , had four previous convictions. the chancellor and prime minister

given a first hints on what will be the conservative manifesto. theresa may says she would keep the current spending on foreign aid despite pressure within our own party to cut it. the chancellor has hinted that he would like to end the party's promise not to increase taxes. i deputy political editor reports. no leader stays popular forever, leader stays popularforever, but reza made feels she's liked enough for now to make policy some might like and others won't. she was confident enough, have promised when we heard before and will again. melo my passion in politics is to make the united kingdom a country that works for everyone and notjust the united kingdom a country that works for everyone and not just the privileged few. that today that meant sticking to britain's target for spending on foreign aid, which some right—wingers want cut. for spending on foreign aid, which some right-wingers want cut. we need

is look at how that money is spent and make sure we are able to spend that money in the most effective way. but what about that other costly pledge? keeping up the value of pensions? again today, you are telling the country that you are a leader that people can trust. can pensioners trust you to go on raising the state pension year by year, just as your party and government is now? what i would say to pensioners isjust look at government is now? what i would say to pensioners is just look at what the conservatives in government have done. p yesterday, £1250 a year better off as a result of action taken. we were clear about the need to ensure that we support people in their old age and that is what we have done. that wasn't a yes. here and that is what we have done. that wasn't a yes. here in baxter, plenty of people like the idea of looking after pensioners. they have worked all their lives, paid their national insurance. i think they deserve it as much as anyone else. if if you

can't look after the elderly, what can't look after the elderly, what can you do? if it can be done, stop it. a lot of them put it in the bank. trees may may be about to upset a lot of voters, even thinking about dropping the tories promised to pensioners takes a leader very confident about the election, especially now she is protecting overseas aid spending. a big lead in the polls comes in handy if you about to annoy millions of pensioners. a big majority in the commons, even more so pensioners. a big majority in the commons, even more so she then on and doesn't. that deserves a hug, jeremy corbyn parred campaigning his way to small crowds and big ones. no talk of saving on benefits here, the carbon wayside like this. theresa may seems incapable of answering any questions about the protection of the triple lock. i give you that commitment now, labour will maintain

the triple lock. standing by what is called the triple lock, painted up every year by inflation or average earnings or 2.5%. and not sure where i'm going. nor is anyone for sure, the campaign has barely started. the lib dems look perky, they are sure this election will be better than last time. and we are the only clear opposition to the conservatives, opposing a hard brexit, it and being a clear and effective opposition on every other level. and on they go. pollsters and pundits may think they know how this ends, but there are still 48 days to polling day. the internet is creating a new kind of criminal according to a new report from the uk's national crime agency and that criminal is younger and far more tech—saavy than many of the others law enforcement are used to encountering. the agency says an increasing number of young people are slipping into a life of cyber crime. doctor merry 18 is a cyber

psychologist who has done extensive research on the pathways young people take to cybercrime. what sort of person is attracted to the world of person is attracted to the world of hacking? we published a report last year where we found that the typical profile of the youth hacker was male, highly intelligent, clearly had an avid interest and skills said regarding technology. had some need for affiliation and affirmation, so to a group, and also enjoyed the challenges involved in tracking behaviour. how do they take that first step onto that pathway to crime? it's a good question. we know

a lot about real—world criminality, we know very little about cyber criminality. where the pathway from into cyberjuvenile delivers the bank potentially into organised cybercrime will stop we do need more research in this area. there is no point and actually considering hacking when a young person is 15, they don't just wake hacking when a young person is 15, they don'tjust wake up and become a hacker we have to go back in a developmental context and start thinking about identifying these kids very early, and i'm talking about school entry age. we have io metrics and c0 metrics, but we have no co, we have no technology quarter, everywhere in the identify these kids we would be able to engage with them, nurture them,

during the educational process and stop them going outside the system to seek affirmation. that also is very technical. how easy is it to achieve? it is to design a scale, and that's a major piece of work for behavioural scientists, but it is not such a big thing to do for them, a scale would be an assessment that you give to young children and you would aim to identify latent talent of talent that would manifest over time. at that point, you could then hot house them and get them to engage in parts of the curriculum where they could build their self—esteem within the educational system rather than engaging in potentially criminal behaviour. that isa potentially criminal behaviour. that is a way of staging an educational intervention. in addition to that,

we also need to stage interventions in terms of the actual behaviour. it would be very difficult for any pa rent of would be very difficult for any parent of a tech talented 13—year—old to explain to them, well, if you are engaging in this behaviour online and you are at the perimeter of the network, that is 0k, perimeter of the network, that is ok, but if you do this in terms of penetrating the network then that is criminal. it would be difficult for a teacher to teach that to a young person. what we need is extensive education. sorry to interrupt, running out of time. teenagers and consequences. thank you very much. hugh ferris has these bought for us. they've met in two of the last three finals... but this year... there'll be a madrid derby in the semi—finals of the european champions league. real have been drawn against atletico in the last four... where surprise package monaco will take onjuventus in the other match. it is friends reunited because it is

balance and stumbled over... but he did recover well to take it 6—3. but it was the number ten seed who progressed despite the serb saving four match points... as goffin set up a last—four meeting with nine time champion rafa nadal they say that when ding junhui plays snooker... there's over a billion people glued to their tv sets in china. well you can bet there's even more watching his second round match at the world championship in sheffield, england as he's up against china's number two player liang wenbo for a place in the quarter—finals these are live pictures from the crucible... ding leads 9—6 so this is the final frame of their session before they finish tomorrow meanwhile one of her grandchildren, the duke of cambridge,

a shot to the system next week as winter makes a return. but funny weekend it will be mostly dry. it will be some ground frost and it will be some ground frost and it will be some ground frost and it will be quite chilly overnight. some sunshine today by the cloud has been building up as the day goes on and so building up as the day goes on and so this taken late in the afternoon in lancashire. the best in the sunshine to end the day has been any north, but hide our weather front, because the holes filled in the cloud over the south—west of england. while we had 19 yesterday, we only had 11 cells yesterday with chilly air. that makes its way southwards through the night, that means ground frost for northern england and scotland, but where we have that weather front close by northern ireland, central areas, will keep temperatures higher with a bit of mist and fog around dawn. disappointingly cloudy for some to start the day, but beautiful sunshine any north just a little chilly. showers get going fairly quickly and they will be wintry over

the hills. we will see a lot of dry and reasonably bright weather, just the odd drizzly shallow left, so a good chance of some holes in a cloud developing, east anglia, midland, pa rt developing, east anglia, midland, part of wales, but that weather front is never too far away, and it will make inroads back into northern ireland to the last part of the day. chavez wintry in nature across northern scotland and particularly in the aisles. there will be sunshine blowing between those showers. clearer skies to saturday night it will be called in southern areas with a touch of grass frost. starting to turn more unsettled on sunday in the north, while for those marathon runners and spectators that is likely to be chilly sunday morning. a little bit of sunshine, it will warm up, are probably better with the cloud on balance, but that is good running weather. good sunshine around on sunday, and where we do see it will be 14—15dc, but in scotla nd we do see it will be 14—15dc, but in

scotland it is a change later in a day. low—pressure approaches, poses the risk of gales, heavy rain, but what is interesting is that once that's good way to scandinavia, the cold front will get an icy blast of arctic air and wintry showers possible anywhere. the latest headlines. the gunman responsible for the attack in paris on thursday has been identified by french media. handwritten note defending the so—called islamic state group was reportedly found near where he was shot. french security forces have been fully mobilised ahead of sunday's residential elections. the prime minister said hairs everything will be done to ensure the vote goes smoothly. —— says everything will be done. at least 19 children were killed when a minibus collided with a truck east of pretoria. police
