Right now we want to break because we want to go to a nbc special report on the Parliament Incident on lockdown. Good day, were coming on the air because of one possibly two security situations unfolding right now in Central London. The report of shots fired outside of parliament. The house of commons was in session and the parliament was put on a lockdown. Lets get more now from kelly ko cobiella. It looks as though there are two separate incidents, one on the Westminster Bridge, the the houses of parliament across the tems and it now appears as though a car hit several people, a crowd in Westminster Bridge, at least five people were hit by that car. They are now being treated from what we understand. And a separate incident close to the houses of parliament very close to the houses of parliament where a man believed to have been armed with a knife threatened a Police Officer and was able to get into the confines of the parliamentary building. The leader of the house of commons has confirmed that that man was shot by police. That information has not yet been confirmed by met police. What were hearing on the official channels of met police is that theres a firearms incident in Central London that they are aware of this but they are not giving details. Lester, one more note to add, this would have been a busy day at parliament. Its wednesday, when the Prime Minister goes to the houses of parliament and addresses fellow mps and talks about the state of government and policies. We understand that the Prime Minister is safe and at work. Her location not being disclosed. Lester . Were looking at a picture right now Westminster Bridge and vehicles stopped right there. Is it your assessment right now that whatever happened is contained . We havent heard officially from met police whether they are looking for more than one suspect, whether they have stopped a suspect or whether anyone is in custody or has been stopped by any means, shot or otherwise. All we have in terms of suspects or attackers is this information from the leader of the house of commons who has said that one man has been shot at the houses of so again, lester, this leaves in question exactly what has happened on Westminster Bridge aside from a person in a car running into a crowd of people and injuring at least five. Thats where we stand as of now. Were looking at a live aerial view of the bridge itself where we believe that some people have been treated there. The camera now focusing in on what appears to be people on the ground around the double decker bus. How this relates to what happened on the grounds of parliament is not clear right now but you can clearly see activity, First Responders around that bus on the bridge. This bridge leads across the te temps and to parliament. Very close together here. Early reports are of the shots fired, there was a statement by the leader of the house of comm w was shot by armed police. Air ambulance is currently on the scene to remove casualties and then he notes in a statement further violence in the vicinity of the palace of westminster and hopes colleagues on all sides will certainly stay in touch with all of this. Bill neely is in london. What do you know . Yes, im in Central London at the moment. It does appear that this is some kind of terror incident because it does appear there were two incidents. In one a man got inside the grounds of westminster. Remember, this is the seat not just the British Government and parliament but of british democracy. He appears to have been armed with a knife. He was challenged by two Police Officers and it does appear that that is a sailant was shot by armed police. At around the same few hundred yards away, it seems that a vehicle is being described as a 4 x 4, a vehicle that would hit with considerable force, knocked down foblly five people on Westminster Bridge. There are pictures on social media and video on social media of some of the people lying on the ground. We dont know what condition they are in and so far the police have not given any details of injuries or indeed of appears to be a double incident. At the very center of british democracy and obviously london has been subject to terrorist attacks in the past and ones mind immediately goes to paris and brussels and the other European Countries that have suffered terrorism in recent years. So clearly a very serious incident or two incidents here. As we look at another live view, this is just the street that leads across the bridge there. You can see the Police Activity. We saw what appeared to be First Responders tending to individuals on the bridge itself that would be the second location. First location is the parliament itself where police took down an assailant there. No one officially that we know of has characterized this as a terrorist incident. Were certainly aware of what happened and past year in nice and also more recently during the Christmas Holiday in germany involving vehicle attacks and authorities around the world have tightened their security and have kept that in mind, the possibility of these kind of attacks. Here you see a very up on the sidewalk there and what appears to be medical attendants dealing with people, potential casualties there on the street and sidewalk leading to the its mid afternoon in london right now. If you just joining us, were watching two likely related but not clear situations unfold, there were shots fired outside much parliament and then a vehicle moved into a crowd of people on the bridge, Westminster Bridge. Its a very popular tourist location that people come to get a look at big ben. There you see as the camera widens out more of parliament, kelly, are you still with us . I am, yes. Is this being characterized beyond just two separate incidents . Well, officially they say they are dealing with two separate scenes here, lester and we do know this has been the fear of police for years. Theyve warned repeatedly t theyve talked about how many terrorist attacks they plots that they have foiled, not to say that this has been linked to terrorism, it absolutely has not at this point but it has that same significant as other types of attacks we have seen in other parts of europe. The question here is was this involving more than one person . Was there an attacker on the bridge, which is i think what you were getting to, was there an attacker on the bridge potentially on the loose . Was there someone else attacking parliament or is this the same person who is now been understand shot somewhere in or around the grounds of parliament. That we simply dont know at this point. Met police have said they have closed the westminster underground train station v thats if youve been to london and ridden the tube, that pops you right out at the corner of Parliament Square and takes you right up to the foot of far limit. So that may be an indication that perhaps they are either trying to keep people out of the area or they are trying to keep any possible suspects in or a combination of the two, lester. And there were reports again of a Police Officer stabbed at parliament. Police shooting the assailant there sean again, how many other people may be involved in this is unclear. A moment ago we saw a medical ambulance outside the grounds of parliament to take some of the casualties away. We have seen par medics on both sides of the bridges, First Responders, apparently tending to individuals. This is a pretty broad area because were see being activity on both sides of the bridge as well as in parliant clearly they are working several scenes here across the bridge. You can see the camera continues to move and people being tended to all along the bridge. Traffic obviously stopped. Were told that parliament was placed in a lockdown, house of commons was in session. It was quickly suspended at the sound of shots people reporting hearing shots outside parliament. That would have likely been the Police Officer responding to that assailant with a knife. Now you can see all across the bridge, different spots of Police Activity and what appears to be medical activity as well. If we have been to london, this is a place you have likely been to. It is a very, very popular stroll for tourists across the bridge and who want to get a view of parliament and the temz, it would have been a little after transpired. Heeshz heres a view as we look on the bridge, paramedics appeared to have set up a triage area there. We dont have a number of injured or casualties but we are just watching this play out and obviously, unfolding situation. Police and metropolitan police and london getting a handle on this. Obviously security throughout london would be on high alert as investigators try to get a handle on how broad this may be or whether this was limited to what were seeing here. These two incidents in and around parliament. Im just watching as that camera moves in. Its hard to get an idea. We heard reports that a vehicle, a truck may have plowed into the crowd. The fact were seeing people treated h intervals along the bridge would perhaps suggest it could have been a moving vehicle but we dont have confirmation right now. The report again, parliament in lockdown. Assailant stabbed a Police Officer, shot by police and then police also responding to this incident on the Westminster Bridge that has not clearly been identified as to what happened here. You can see the enormous amounts of ambulances and police and tourist vehicles stopped in the middle of this. We dont know whether they were people still on the vehicles but it is likely whatever happened it was witnessed by a lot of people, not only a duck boat there in the double decker tourbuses but a lot of pedestrians would be making their way across the famous bridge this time of day to capture the sights and sounds there. We saw a medical helicopter o was called in to take away the most serious casualties, theres First Responder and helicopters moving through the frame as we continue to watch and watd and get a sense of exactly what has unfolded. The order of how it unfolded and how Security Forces in london may be preparing for the event youllty that this goes beyond these locations. Kelly cobiella is monitoring from the newsroom in london. What more can you add . Well, we just got off the phone with a member of the house of lords, two chambers in the houses of parliament, the mps and house of lords. And this member said he is inside. That he and others have been told to get in their offices, to barricade themselves inside in case of another point inside the houses of parliament. We do understand that from the house of commons leader that an officer was stabbed inside the grounds, whether it was inside the building itself, we dont know. An attacker was shot by police and the question is, if the staff and Civil Servants and elected officials inside that building are being told to barricade themselves inside in case of another person on the loose. The question becomes, was there more than one who got into this government building, the seat of power in london . We dont know the answer as yet. And what are we lets walk back a little bit as to the situation that has unfolded across this bridge any indication it was shots or a vehicle . What do we know . It now looks originally there was confusion, around i guess it was about 40 minutes to an hour ago now, we heard that there was a firearms incident that came directly from police in london, that they were dealing with a firearms incident on Westminster Bridge. Then we started to see the results on social media as well as the live cameras here from our local partners here showing something very different, showing some sort of 4 x 4, very large vehicle that had run into people on Westminster Bridge. This would have been a very crowded place at this time of the day. There would be people walking back and forth from offices on their way to meetings and then you add in the tourists. So this is the second second report we received, which is really from witnesses and just from the video on the ground lester, of a car, a 4 x 4 mowing down ppl bridge. In addition to that, a reuters photographier reported seeing at least half a dozen people injured on the bridge. Were not sure if any of those people, if there was a firearm incident in addition to that, if any of those people were shot in addition to being hit by a car. But we do think the primary weapon if you will used on Westminster Bridge was a 4 x 4. The scene were seeing now, this is the original scene as we believe, youre looking on the grounds now of parliament and First Responders, we believe that would be the scene of where an officer was stabbed and another officer returned fire. This was the separate scene from what you were witnessing which was a short walk away. Clint van zandt is a fbi profiler and joins us on the phone. Clint, we have seen time and terror incident, a low tech kind of incident. We saw in paris a few days ago on assailant trying to take the gun from a Police Officer. If this was terror related, a vehicle, ea knife, very low tec. This is something that i would suggest that cities would have a hard time defending against. Well, very much so, lester. Anyone can acquire a knife. As you have witnessed, and reported on over the last year and a half or so, weve seen trucks use multiple times and middle eastern terrorist groups advocate the use of either a knife or a truck to go into a crowd. Unfor natdly this is notng new but it is without advanced information of something thats going to happen, its very hard for Law Enforcement to intervene to stop Something Like this. Crowd before anyone can respond. Of course someone holds a knife, its up for an officer to act, react when he or she is confronted by Something Like this. So its ver low tech. It doesnt take a lot of planning organization, but it can be very effective nonetheless. We heard kelly note the tube subway through the area has been suspended right now. When Something Like this happens, is it typical that they will begin looking at other places and have to assume that this is not limited to what were seeing here . One of the great things about london, one of the most wonderful cities in the world, you and i both travel here. The camera system is so unique. Ive been at Scotland Yard and see how they monitor the cameras. There are cameras ats every intersection and every street. One thing law coordination with either the truck or vehicle that the individual with the knife might have gotten out of. Then theyll back those cameras up. As you know, they start just like a bullseye on a target. They start with the incident took place then start backing up, both with the investigation as well as their review of cameras and theyll do the normal things that the fbi or Police Departments would do, theyll look at the license, the fingerprints of the individuals, trying to develop is this a wider net. And its important right now, if these two events were in fact linked, are there any other events going to take place . I would suggest that London Metropolitan police are in a very high alert right now. Im thinking safe to assume that alert is probably certainly being noted in this country as well as other capitals and cities as the Westminster Bridge. And paramedics and medical attendants treating unknown number of casualties there. Were approaching the bottom of the hour. If youre just joining us, lets recap where we stand. There are two unfolding an assailant tried to stab a Police Officer at parliament while the house of commons was in session, was shot, people reported hearing shots outside of parliament. There appears to be a separate scene there a short distance away, the bridge youre seeing there, Westminster Bridge, theres been an incident that may have involved a truck plowing into individuals. We have seen a number of people treated on both sides of the bridge and air ambulance on the scene, we have seen ambulances and people taken away on stretchers. Kelly recap what we know right now, kelly. All of this started about 50 minutes ago, lester. It was 2 40 in the afternoon, british time. It would have been busy afternoon right in the heart of london. The first reports that came in around 2 40 were of an incident on Westminster Bridge. This is the bridge we keep seeing in these pictures, that leads straight to far limit, crosses straight to the steps of parliament. The initial reports were of a firearms incident on that bridge according to met police. What weve subsequently began to hear into crowds on that bridge, it will sound familiar because thats exactly what happened in berlin and in germany and in france in the south of france and terrorist attacksth statement. I should be very clear that this is terror related at this point. This is very much an active investigation, they arent labeling it as anything other than a firearms incident. We understand from eyewitness reports, nothing confirmed from police, that half a dozen people, about six people were injured on Westminster Bridge. It could be more than that. These are preliminary numbers and then secondarily, another potential scene, a man according to witnesses brandishing a knife at the houses of parliament, threatening an officer with a knife. An officer according to one official member of the house of leader of the house of commons saying that an officer was stabbed on the Parliament Grounds, that that attacker was then shot. This was e parliament. Full building, people inside have been told to shelter in place to take in offices and barricade themselves inside in case there are other potential attackers inside that building. Parliament has been locked down and work stops. The Prime Minister is said to be safe and at work. Her exact location undisclosed at this time. Thats where we stand. Kelly, thank you. We want to know President Trump has been briefed on what is known so far about these incidents in london as the camera widens out. We want to go to bill neely making his way closer to the scene. Bill describe what london is like right now as you make your way there . The streets are beginning to empty and an ambulance has gone past me at police are pushing people back to the immediate westminster area. Adding to all of the caution that kelly has outlined, the westminster area is extremely well secured. It is usually teaming with armed police protecting the houses of parliament and it is a very long time since there was a terror incident there. I recall it was in the 1980s, when a conservative mp, a friend of the late Margaret Thatcher was blown up actually when his car rigged with explosive detonated as it exited the houses of parliament. That is roughly the same area where this assailant is set to be armed with where a knife is taken down by Police Officers. As kelly as rightly said, we should exercise caution. Word terror. There are two incidents it would be a huge coincidence if they werent related. We cant necessarily relate that. As you were speaking, we got word London Police say they are in fact treating the westminster attack as a terrorist incident, quote, until we know otherwise. That is the way they are approaching right now and seem to be suggesting these are all one incident. You see Police Officers running back towards the bridge. We dont know what may be prompting the certain rush up as they make their way. Appears to be a lot of activity around the car. We heard about a 4 x 4 but theres a vehicle that looks like a small suv on the sidewalk. We dont know if that is the vehicle that took aim at people as they were on the bridge. But you can see a great deal of activity sides of the bridge. In white, you see evidence collectors who will process the crime scene and try to glean whatever evidence they have. We dont know if the same person who may have driven across the bridge, if the same person who pulled the knife inside parliament. So many questions being asked right now but obviously the first priority, treating those who have been hurt and certainly trying to assess whether this is limited to what were seeing here or it might be part of a broader attack. As kelly noted, we have seen a number of low tech terror type incidents in recent months. Nice, france, a truck in berlin, a truck into a crowd in france only a few days ago at the airport, Police Attacked by an assail w of the officers weapons. So we have seen a pattern of attacks that would take a great deal of coordination or knowhow. This is being considered by metropolitan police as a terrorist incident and until they know otherwise. Camera moving back across the bridge, tourist buses stopped. Vehicles on the bridge stopped. We presume these people have been evacuated but many of them will also be witnesses to the apparent horror that took place on the Westminster Bridge this afternoon, we have noted this is a very, very popular tourist i can add something to that if you want. Yeah, go ahead. Just worth noting that a few years ago, two assailants in a car knock d down a man who turned out to be of those assailants rather brutally murdered that man and brandished the machete to cameras who turned up. I know, that was a clear terrorist incident against a man who was a british soldier. We dont know what the motivation of the person or people involved in this incident was but as youve noted weve seen it before and weve seen it in israel and seen it where people brandishing knives attack soldiers, weve seen it in nice using a vehicle. This is the very easy way that people of a certain persuasion can kill in the modern day. Bill, we have certainly seen over the last few years, a series of terror incidents in the central europe. But and notwithstanding the incident you mentioned there, has london has safer, not other reason having a body of water between them and the rest of europe . Two things. Youre absolutely right that there is a body of water. The Antiterror Police and indeed mi5, the Domestic Intelligence services, foreign intelligence services, you know have been tracking numerous terror plots but also, people in the uk remember the bombings on the 7th of july and indeed the day after london olympics, bomb igs that killed more than 50 people. A lot of people in london have been wondering not if they were going to be attacked again but when. They looked across paris and brussels and braced for similar attacks. London endured decades of ira terrorism in the 1970s and 1980s. Incidents but you know, as citizens in that jerusalem and tel aviv have discovered you dont have to have explosives and how a mercury tilt switch device works to be terrorist. You can use a knife or a man with a machete and create terror. So people in london are i think shocked today and we are all of us i think braced looking around wondering is this the only incident or rather like the paris attacks when there were four separate locations is there more to come. Theres plenty of evidence of police on the streets right now. Im looking at them who will be braced for more. Lester . Bill neely thanks as we watch that medical from the lawn in front of parliament possibly taking a casualty away from the scene. And the Police Activity that extends from parliament across the Westminster Bridge from vehicles of what we believe is a vehicle attack, the attack on the Parliament Grounds themselves was a knife attack, Police Responding with gunfire. Kristen welker is at the white house. What is the white house saying . The white house confirming the president has been briefed. This started to unfold as the president was holding a meeting with women about health care. That was the big focus here at the white house this morning. Ahead of that big vote thats expected on capitol hill tomorrow and republicans plan to repeal and replace obamacare, now its going to shift. The president asked about this hif news and i think we have a little bit of what President Trump had to say moments ago. Just getting an update on london. Big news having to do with london that just happened. Lester, having covered the white house for several years, i can tell you that the president will continue to get updates throughout the day from his National Security team. They will monitor this situation very closely. I was back in the west wing and i can tell you that top officials huddled trying to get the latest information on exactly what is happening right now and of course the United States has no closer ally than britain. In fact, President Trump met with the Prime Minister of britain, theresa may, back in january. To i would expect that were going to see phone calls take place at the highest lev the white house continues to monitor this ongoing situation, lester. Kristen welker at the white house where they are paying close attention to this as they are in cities likely across europe and across the world here as this appears to be a terror attack. Thats how metropolitan police in london are characterizing it right now until they get information to the contrary. You can see the littered scene there along the Westminster Bridge of where paramedics have been treating victims of this attack. We dont have a number right now. It sounds like maybe we had a witness there. I guess they cutaway from it. If we hear from someone well get to it. Early indications theres many as half dozen people on the bridge but that is not confirmed by the metropolitan police. There was apparently a vehicle involved. We dont know if its that gray van there. Hard to know right now where that vehicle but a lot of activity right there. I believe we have bill bratton with us right now, former new York City Police commissioner and nbc security analyst. Are you with us . Yes, i am. Good morning. Good morning, this is i know this is the fear of every police department, a low tech attack. I know on the job you had to worry about everything from Nuclear Attacks to plane attacks but Something Like this is there a defense . Actually, there is but the reality is that theres no perfect offense. The Saint Patricks parade, all of the cross streets going to the parade were basically block t ed off by a heavy duty dump trucks that the city has. Its a precaution we never used in years past but routinely now use. One of these inspired eye vents about encouraging an individual to use a knife gun or car everything coming out of there Law Enforcement source information, its very preliminary, it looks like it was a deliberate driving of a vehicle into a group of people. Suspect attempts to flee the scene and is being counted as what would be metropolitan Police Officers in the vicinity of the parliament building, right there at the Westminster Bridge. At least one of those officers fired until the suspect still undetermined the last information i have a few moments ago, as to whether there was a Law Enforcement officer stabbed in that incident. It seems to be up in the air at the moment. Thats one of the early reports we have and as you certainly know, early reports are not always the most accurate. Everything is preliminary. You always start off with preliminary. I know that in new york city, obviously new york city has dealt with the real thing but certainly preparing for this sort of thing is a daily occurrence. On may wy way here i saw new yo city tactical teams at one of the landmark locations in the city. It is part of life and the expectation of these sort of things, isnt it . In new york city particularly, that new york residents tourists alike, you cannot not notice the police during night time. We increased by almost 1400 the number of specially trained officers with the heavy weapons and the arment and specialized vehicles at any given time in new york city theres quite a few of these officers visible at all times. As just done this morning as a result of what happened in london, going on high alert and number have been positioned around government buildings and the city always concerned about the copycat or the idea this might be part of a larger series of events planned for multiple cities. In new york were very fortunate that resources were provided over thet allow for that expansion and its appropriate. The world was changed draw mattically and inspired type of attack is the one were most fearful of. Bill bratton, if you can hang i appreciate it. May be familiar to our viewers as someone we rely on for information about the royals. I understand you were a witness to some of the activity. Can you tell us where you are and what youve seen . Lester, yes, i was in the very bottom addition to the traditional houses of parliament that viewers will be familiar with and basically its an nexed by a corridor which is outside and people walk to it to get to the main chamber where we see the Prime Minister and quite earlier today thats where it was taking place. I was in this modern building next door and heard gunshots and absolute commotion and people beingor and everyone in westminster has coffee and the call went out to run, run, run. We then run to the back of the building and likely commotion outside. An Immediate Police presence through the brass doors at the end because we can see out from the bridge and seemingly something going down past the escalator. And obviously having now been in a lockdown situation were trying to get information in that but we understand that there the bridge very close just walked throughout the building because the police have been ushering us to get further and further into safe. And enormous Police Presence on the bridge. Iconic london stopped in their tracks. But the air ambulance, we understand allegedly being stabbed and obviously the now on lockdown. Were you able . You indicated that you were aware of something happening on the bridge. Was anyone able to see out the window and see exactly what was taking place . Not from where i was, we were at the back of the building but the building is an atrium and made of glasses. Its the main entrances and from there we can clearly see a major Police Presence. Usually thats cars running past and tourists and almost within minutes really of the gunshots beg heard and people being told to run, run run, the entire area became a lockdown. We can very easily see that theres been a complete lockdown of that area. We know that the station has been closed and we know from just being in westminster everyone is being told to move away from where the incident happened and go to the safety of their offices, at the moment ive been m building that is just been assured by Police Spokesman here amounts to the gathered and worried crowd that we all face here and building surrounded. Getting the impression at the moment, that perhaps there is an ongoing element here. Youre essentially in lockdown and not free to leave the building right now. Yeah, everybody who has been inside the precinct of the houses are parliament, old building and some of the newer buildings are all in lockdown and police completely surrounded the entire area. No getting in or out. With reference to the lawmakers, the house of commons was in session, they are being kept in the same area . Yes, all of the lawmakers will have been told probably the same advice go to safety of offices. Obviously wednesday is a busy day in parliament. Article 15 next week, lots of action here anyway as we go to rece recess. So theres a sense its a populated time to be in westminster on this particular day having literally being in chambers doing the weekly questions hours ago and people have had to be moved to positions of safety from where the main incident happened, a matter of meters from where im safe. Let us know if the situation changes there. U. S. Department of defense and also with the cia, jeremy, would there be any kind of intelligence that would point to Something Like this or might this be as Brill Bratton noted one of those inspired attacks that dont pop up on the radar . Look, what the British Secret service mi45, the internal Security Service is doing right at this hour with new Scotland Yard, tearing apart any potential evidence that they have. They are looking at the vehicle. Fingerprints an any other information from the alleged assailant that was shot. They are going to scour social media and look at any claims of responsibility that isis or any other known terror groups have put out there on the internet. So they are going to look at any potential threats that have indicated an attack on london and attack on parliament or an attack on these particular targets. We should note, lester, that this apparent terrorist attack and again, at this hour its not fully confirm d it is a terrorist attack, that this comes one day after the uk joined the United States department of Homeland Security in issuing a terror warning about Aviation Security about flights emanating from the middle east. The uk did join that terror alert and threat and basically banned certain Electronic Devices from the aircraft. We dont yet know whether or not this attack is in any way either linked to that terror stream or potentially a response to the actions by the government. Its too soon to tell. I think what people are focusing mostly on now is the fact that isis has in the past particularly in 2014, directed all of its followers, to take any measure at all to attack quote the disbeliever. They said in their published statements, you should run over them with a car or stab them with a knife. Weve seen those stabbing attacks before. Weve seen the horrific car ramming i want dent that claimed the lives of 73 people in nice, france last year. To a Counter Terrorist official in the British Secret service and mi5 or here in our own american intelligence agencies this has the hall marks of a terrorist attack but we dont know what the particular motives are. Metropolitan police calling it a terror attack until they get information otherwise. But you have been on the inside jeremy when these things happen in europe. What does that trigger in washington . What is probably now in this country . Well, first i think the main locust of activity is the National Counterterrorism center in the washington, d. C. Suburbs, they have the lead to take all information in the government, all open sourced information and information that isis has put out online and any classified intelligence thats in the holdings of the National Security agency or the cia or any of other agencies, pull it together and figure whether or not anyone has claimed responsibility. If theres any information on these alleged assailants and any potential links back to known terror groups including isis and al qaeda. We should not forget about al qaeda, most people do focus on isis. Al qaeda remains a very potent terror threat. Thats the work of the National Counterterrorism center here in washington, d. C. Suburbs, they are pulling together all of that information and will brief it up to the chain to the National Security council and talk to r throughout the middle east and europe. One of the things that happens in a situation like this, counter dsz terrorism experts who get on the phone on secure lines, very quickly and often times throw up a video teleconference of people with any information about this and share any tidbit of information they have that can lead them to analyze this threat and potentially protect other areas from future threats. All right, jeremy bash, thank you. As weve been watching and youve been speaking, were still seeing injured, casualties being taken from the scene. Police and fire and paramedics set up a robust triage setup there. We have seen what appear to be injured people all along the length of the Westminster Bridge leading to parliament where we got the initial indication of shots fired. Mid afternoon there in london and then words of a vehicle that apparently was plowing through the crowds of people on the bridge itself. You can see the famed double decker bus happened. Theres a photograph taken earlier here, photos were just getting in of people on the sidewalk, on the bridge who were apparently victims 6 this vehicle that plowed through the crowds. We dont have a number right now. Early indications again that there was this began with a knife wielding assailant on the grounds of par limtd and he was shot by police the parliament placed on lockdown and again these are first images were getting of people who have been injured. This is obviously right after it happened because its before you see any paramedics at the scene. Heres a shot of paramedics rushing to the scene. And police and security now moving towards parliament as they begin to secure the area. Again, they have to assume that the attack or whatever is happening is broader than just what were seeing here, that this might reach into other areas of london. Theres the front of the vehicle that this may be the vehicle that drove into the crowds. You can see the damage the dama vehicle. We were told it was a 4x4 that had crashed into the crowds of people. Lets go back to Kelly Cobiella who is monitoring the situation. What else are you hearing . Were starting to get some information and some eyewitness accounts from people who were at the houses of parliament. You just spoke to one of our contributors mostly on royal stories. Were also hearing from a man who we work with quite often who was on the ground at the time. He heard something happening on Westminster Bridge, but didnt actually see it it. The first thing he saw was a heavy set man running toward the gates leading into parlment. The traffic. The eyewitness ran in through the gates holding what looked to be a knife, attacked a Police Officer with that knife and the Police Officer fell to the ground. Managed to get away from him and he ran toward the entrance to the house of commons, which is the part of parliament used by the members. He was then shot by police. Its not clear how many times he was shot, but we do hear from the house of commons leader this he was shot by police. That has not yet been confirmed by the met police. So two separate incidents, lester, as you mentioned. This incident on Westminster Bridge and then the incident at the houses of parliament. It is entirely possible that it was that it all took part with one attacker who drove across the bridge into crowds, gout the gates at the houses of parliament. Lester . Are you hearing anything in terms of the number of casualties on the bridge . Kelly, you still with me . We lost kelly there. But we continue to watch paramedics on the scene right now. They have been treating the casualties. There was an initial report of six but we saw the still photos of a number of people on the sidewalks down who had been hit by this vehicle. You see some of the early photos here before help had arrive d. People on the pavement, on the sidewalk, and they are still treating them now Late Afternoon there in london. How this relates to the assailant and whether its the same person at parliament is the big question right now. We heard from our correspondent bill neelyha well continue to follow this story as details warrant. Well come back on the air and full coverage to be the on nbc nightly news.
