Champs elysees and i can see armed Police Walking down the main part of the road. I dont know if people we re the road. I dont know if people were in the restaurants and hotels which line the Champs Elysees, whether there are still in there and under lockdown, it is getting close to midnight. Very nervous seen on that part of the Champs Elysees. The Police Operation in terms of looking foran Police Operation in terms of looking for an accomplice is over in this pa rt for an accomplice is over in this part of paris but it is underway in other parts of paris, to the east of the city they are searching an apartment. I was telling you a short while ago we believe there is an Arrest Warrant that has been put out for a second suspect. We dont know whether he was on the police say they are looking for second suspect who came into france from belgium. They were, of course, feel full that Something Like this might happen in the run up to the election. In fact the run up to the election. In fact the police said in certain parts of the police said in certain parts of the country they would bring in private Security Guards to protect Polling Booths but as katya adler said there is a realfearfor the election, with some candidates cancelling their rallies tomorrow but it will have an effect on turnout as well because some people quite simply will be too afraid to turn out. Christian fraser in paris, thank you. Thats it from us. They will be continuing coverage throughout the night on the Bbc News Channel but on bbc one it is time for the news where you are. Goodbye. You are with us for continuing courage of the major security incident. A french policeman has been killed and two others wounded when the bus in which they and other officers had been travelling in was targeted on the Champs Elysees in central paris. A gunman in the car, from which the shots were fired, has been killed. The world famous street was crowded when the attack started and tourists and passers by ran from the scene. The French InteriorMinistry Said the officers were deliberately targeted in what was probably an act of terrorism, which comes days before the first round of the president ial election. Two of the candidates said they have cancelled campaign for friday. A State Of Emergency is still in effect in france following the mass killings by islamist extremists in paris in 2015. This is what one eyewitness, ogur, had to say to reporters just a short while ago. We were moving towards a car and then i heard two or three shots, but i didnt realise they were shots to start with. Then there was just panic all around. Everyone started running down the Champs Elysees, just by instinct. I didnt stop to work out what was going on. I just ran too. There were some police already in place. They were blocking the road with their trucks. Itjust took shelter behind them. I really cant say what was going on back at the scene. I didnt have time to do anything other than just run away. The police are very keen to get people off the street, away from the Champs Elysees. Lets listen to the warning there were giving the people on the street. Stay back it is dangerous the Police Clearing the streets, getting people to safety. On the line is thierry arnaud, Chief Political reporter at the french broadcaster bfmtv. Your reaction to what we are hearing tonight . This has all the hallmarks of another terrorist attack, deliberate targeted attack on police on one of the highest Profile Streets in france. Thousands of tourists and people around us. This clearly was intended to attract the maximum attention in a very sensitive time in france, just before the elections. How significant is the location . It is highly symbolic, and you cannot think of all symbolic french target than the Champs Elysees. This was to have maximum impact and inevitably has done. Some eyewitnesses we have been hearing from have said that they felt police were very much the target here when of course there we re target here when of course there were many other members of the public on the street. They are unharmed as far as we are aware. The first report suggested that the vehicle pulled up alongside a police van and opened fire on the police man who just happened to be here. The are always a lot of police at any time on the Champs Elysees, so there are a lot of enquiries to be done now, but it looks like it impacts on the police force in france. He would be ambassador in paris during some very tumultuous times. There has already been a State Of Emergency in place for quite some time. What more can the french authorities do in terms of providing extra security . They were already planning to have 50,000 Security Forces out and about in france for the elections on sunday, so france for the elections on sunday, soido france for the elections on sunday, so i do not think there is more in terms of security they can do. The experience from a year and a half ago was that people were very determined not to let the terrorists change the way of life or knock them off what they were intending to do. The reaction in paris will be one of real resilience and determination, not to be cowed by this attack. But it will increase anxiety and tension. There was already a plot disrupted a couple of days ago in marseille, said this shows that france is under a high level of threat the moment. Francois fillon according to reuters has been calling for the Election Campaign to be suspended. How likely is that in the light of the fact that france wa nts to the light of the fact that france wants to show that normal life can carry on . I think he has talked about suspending his campaign. It is only one more day of campaigning a nyway only one more day of campaigning anyway in this election because saturday is the day when no campaigning is allowed. The first round is almost over anyway. It is ha rd to round is almost over anyway. It is hard to see that they will actually postponed voting on sunday, and the logic would be that france should carry on and show they will not be frightened away from this hugely important democratic exercise. Frightened away from this hugely important democratic exercisem terms of the timing of this, how coincidental is it that this president ial debate was taking place this evening . I do not think we know the answer to that, but surely it is no coincidence that this attack happened just a couple of days before the first round of the french president ial election, the major democratic moment in france. It feels to me like the timing was not coincidental. We appreciate you talking to us tonight. Christian fraser is on the Champs Elysees. How much clear if the picture becoming of the sequence of events tonight . A little bit clearer. We have had a briefing from the interior ministry. We know one Police Officer has lost his life in two have been injured, and we also understand that the gunmen pulled up alongside this police van, jumped out with a semiautomatic rifle and opened fire on them. I have seen dramatic pictures of the immediate aftermath of the attack were one of the officers is pointing his weapon at someone who is down on the ground, in the immediate aftermath of that when they shot the attacker. The Question Mark was whether there was a Second Attack in the vicinity at the time. We are hearing from reuters that an Arrest Warrant has been issued for another man who is supposedly linked to this attack, who came into france from belgium. We also hear there is no Investigation Underway in an apartment in eastern paris. A lot of friends at work is underway now, not only at the cupboard at the apartment. They are hoping to find out who this person was in contact with in the immediate hours before this attack, and is there someone else they should be worried about . The activity that was happening around the Arc De Triomphe suggested earlier the might of been another attack they were looking for. Very much so. We were down on the pavement and we were watching coming police from all directions and a real hurry. But a peculiar incident was, given the attack was half day down the Champs Elysees, they pulled over a bus down the Champs Elysees, they pulled overa bus and down the Champs Elysees, they pulled over a bus and there were five or six Unmarked Police cars that pulled up six Unmarked Police cars that pulled up alongside it and very heavily armed Police Officers jumped up alongside it and very heavily armed Police Officersjumped out and pulled every on that bus. That seemed to suggest, withoutjumping to conclusions, that someone had gone back bus and they were looking for someone else because there were other buses going around that that the left well alone, said there was a reason they were looking for someone a reason they were looking for someone else because there were other buses going around etoile that the left well alone, said there was a reason the pull back the left well alone, said there was a reason the pull back passover. The left well alone, said there was a reason the pull back passover. In terms of the scene now, there are not that many armed police on the side streets now, it is very much focused on the Champs Elysees, but we have not seen people come out of the buildings, and there are a lot of cafes and restaurants down there, so of cafes and restaurants down there, so presumably they have managed to get some people out, but i would have thought people in hotels have been locked down and told to stay indoors. Far too often, you are having the report of instances like this in the capital. We do have indeed, particularly in the context of a president ial elections, this is a stunning development. The atmosphere around this president ial campaign has been a complete change from a couple of days ago when a couple of alleged terrorists were arrested in marseille, allegedly they would just about to conduct an imminent attack on president ial candidates as targets. It is not entirely clear what they had in mind on who the targets were, but i can tell you that the Security Detail around the president ial candidate has been considerably strengthened since then, and indeed i was at a rally yesterday in marseille when Marine Le Pen and i had never seen so many police vans literally dozens of them, very heavily armed officers, making sure that the rally would ta ke making sure that the rally would take place. How likely is it that there will be any Campaigning Taking place tomorrow . It is very unlikely. I wasjust told place tomorrow . It is very unlikely. I was just told a few minutes ago, it is the last day of campaigning anyway. The schedule was kind of light. But it has been mentioned that the leading candidate Francois Fillon said he would suspend his campaign and he was calling upon the other candidates to do the same. Several candidates over the past couple of hours have actually cancelled whatever it is they had scheduled for tomorrow and they will all make formal statements regarding what happened the night tomorrow, and that will be pretty much it, the la st and that will be pretty much it, the last day of campaigning. The first round of voting is scheduled to be held on sunday. Is there any risk that the authorities may decide it should be postponed . That the authorities may decide it should be postponed . Not so far. Francois hollande has made a statement a few minutes ago, saying that every precaution would be taken to make sure that voting would be as safe as possible, 50,000 Security Forces would be deployed all over the country to make sure that is the case, but so far, there is no intention of postponing the election. There has been a State Of Emergency in place for a long time now in france. When you are out and about speaking to the public, how safe the people feel . The mostly feel safe. You get used to living in a different environment
