breaking overnight, new word from the london mayor and british prime minister after the third deadly terror attack in the uk since march. that city on high alert at this hour as police try to piece together what it behind this latest attack. good morning, i'm dara brown at world headquarters in new york. here's the latest. seven are dead, 48 injured, in an attack in the heart of london around 10:00 p.m. local time last night. the incident began on london bridge as a car veered off the road and onto the sidewalk, hitting pudesrheens. the attackers then fled the van and started attacking people in bars and restaurants. the police killed them within eight minutes from the start of the attack.

both prime minister terresheres and london mayor sadiq khan spoke a short time ago. >> we believe we're experiencing a new trend in the threat we face as terrorism breeds terrorism and perpetrators are inspired to attack, not only on the basis of carefully constructed plots after years of planning and training, and not even as lone attackers radicalized online, but by copying one another and often using the crudest means of attack. while we have made significant progress in recent years, there is to be frank, far too much tolerance of extremism in our country. >> i am appalled and furious that these cowardly terrorists would deliberately target innocent londoners and bystanders enjoying their saturday night. one of the things these terrorists want to do is disrupt our way of life. they want to stop us enjoying the freedoms we have, enjoy mingling and mixing on a saturday night, having a good

time. they want to stop us voting on thursday in the general elections and enjoying the democracy that we have. we can't allow them to do that. we aren't going to be cowered by terrorism. >> no group has claimed responsibility for the attack. here's what witnessing at borough market told our reporters. >> we see the people. >> people are crazy. with the knife, just like, they don't care. >> you saw that? >> yes. >> running fast. they run up, they stab this girl i don't know how many times. she was going help me, help me. i could not do anything. i tried to help her. i was back on the floor, i tried to pick up a chair, just to get away. i couldn't do nothing. >> i saw people running, screaming, somebody was injured, people with blood. when you see these things, you

are sitting in front of the tv. when actually you see people and hear people screaming, it is a different thing. it's scary. >> the white house said in a statement that president trump had spoken with prime minister theresa may on the phone to offer his condolences and full support. trump tweeting we need to be smart, vigilant, and tough. we need the courts to give us back our rights. he later tweeted, whatever the united states can do to help out in london and the uk, we are there. in all caps, we are with you. god bless. lucy kafanov is on the scene with the latest. what are law enforcement official s focusing on and what have we learned about the identity of the attackers. >> the attackers are the focus of the police investigation this hour. the three men who used a vehicle, large knives and a hoax

suicide vest to sew panic, to murder, kill, and carry out this latest incident in london. there was a large raid this morning in the barking area of london, about 30 minutes away from where i'm standing. that would indicate the authorities have been able to identify as lete one of the attackers and are now potentially chasing leads. we have seen a quick response from the authorities. they have been pushing back the police tape. where i'm standing a few hours ago was part of the crime scene. they have now opened up more streets to the public with authorities arriving to the scene, containing the attack within minutes of getting the phone call. listen to how the metropolitan police commissioner described the authority's response. >> we were able to respond to this incident extremely quickly, within literally eight minutes. we were already at a very high level of alertness. it's a very complex and confused scene. and a confused series of events.

so it's important that we first of all make sure that there is no one else outstanding. we don't believe there is, but we must make absolutely certain of that. >> i should emphasize, we do not know the identity of these attackers, we do not know what organization if any they belong to. theresa may said these attacks, are not connected by, quote, common networks, but they are bound together by what she called the evil ideology of islamic extremism, which is a significant clue because this elism is not something we have heard from the police or other authorities here in relation to last night's attack. that coming from theresa may earlier today. >> we understand the manchester benefit concert for tonight is still on with heightened security, of course, but with

respect to thursday's general election, some candidates are suspending campaign events for the day. how are they responding? >> that's right. obviously, the uk in the midst of a heated election campaign on june 8th. most of the major parties are suspending their campaigning for today, sunday, out of respect to the victims and what's happened with the exception of the right wing uk independence party, but theresa may did say campaigning will be back on on monday. authorities sending a strong message that the uk will not cower in the face of terror. >> thanks so much for joining us this morning, lucy. >> also joining me now from london is security analyst, duncan guardm. theresa may suggested this was a case of copycat terrorism. so do you thing this was inspired by the westminster bridge attack earlier this year? >> i would have thought it's

almost certainly inspired by that kind of thing and the nice attack we saw last summer. the methodology was first introduced into the uk in that attack in wulch three, four years ago in which a soldier was killed outside a barracks and we seem to have a spate of these copycat attacks going on. also two foiled attacks between the westminster attack and this attack. there seem to be rather like suicides generally inspire other suicides, we call them clusters, we seem to have a spate of copycat suicide terror attacks. >> british police say the attackers were wearing what appeared to be explosive vests and were later determineded to be explosives. what were the possible reasons for doing this? >> in britain, we have tight control over most explosives and firea firearms. it's hard to get hold to

detonators and plastic explosives and firearms. you have to make them yoursselves. it's very difficult. so rudimentary attacks of this kind are all that's left of those who aren't able to get ahold of those more sophisticated weapons. >> this is the third terror attack in england in the last three months. is it because the area is becoming more of a target, the attacks are harder to prevent or something else? >> we have seen in the last 18 months or so a huge uptick in the number of individuals radicalizes online and getting in touch with isis and a desire to conduct attacks. that has created a huge amonlt of work for the security services, for mi-5 and so-15 at scotland yard to deal with. in fortunately, you can't get all of them all of the time, and that means particularly when they're inspired to do something on the spot and these knife attacks and vehicle attacks can

be done with very short notice. they can react very quickly and get out there, and sometimes that means they're ahead of the security services. >> duncan, the prime minister said there was way too much tolerance for terroristic incidents in the country. what does she mean by that? >> well, i'm not totally sure what she means by that. there has been talk over the last couple years that perhaps an extremist ideology, muslim ideology has got hold in the uk, and by that, they mean strains of islam particularly salafi strains from the middle east and from pakistan, and they feel that that is a kind of exclusive form of islam that encourages people to walk down that road to extremism. but i have to say that the vast majority of people that follow those particular strains of islam would have nothing to do with these attacks and would be

completely horrified by them, and that's the general reaction i have seen in man chestic since the last bombing. >> the manchester attack was less than two weeks ago. after the attack, britain raised their terrorism level to the highest level and was adjusted back a few days later. do you think that was a mistake. >> that raise in threat level was specifically directed at individuals who could have been connected to salman abedi who conducted the attack. the reason for increasing the threat level is because they believe there's a network out there that may commit further attacks or if other individuals sound like they might be inspired to follow up on this attack. so it's by no means clear that will put the threat level back up to critical right now. >> duncan, thank you so much for your insight on this. i appreciate it. >> you're welcome. >> well, the concern to protect people across europe during the busy travel season, we will

examine that next. it's not how fast you mow, it's how well you mow fast. it's not how fast you mow... ...it's how well you mow fast. woooh! it's not how fast you mow ...it's how well you mow fast! it's not how fast you mow ...it's how well you mow fast. they're not just words to mow by, they're words to live by. the john deere ztrak z345r with the accel deep deck to mow faster, better. save 500 dollars on the z525e ztrak residential mower at your john deere dealer today. and it's also a story mail aabout people and while we make more e-commerce deliveries to homes than anyone else in the country, we never forget... that your business is our business the united states postal service. priority: you i decided to see if there was a way for design to play a... ...positive role in what was going on in the world. there's a jacket that's reflective for visibility...

police remain on the scene of last night's terror attack in london. seven people were killed and more than 48 injured. three men drove a van across london bridge, mowing down pedestrians. they than ran to borough market, stabbing people as they went. one witness described what he saw. >> actually, i saw three muslim guys run up with knives, started stabbing this girl. i was defenseless. i couldn't do anything. everybody run, terrorists, they're stabbing everyone. i followed them, went down

towards the west bank, towards borough market. run, run, run. bottles, wine glasses, chairs, i tried to help as many people as i could. >> joining me now is brian dillon, and this is the police unitt that uneutralized the suspects in eight minutes. tell us how it all went down? >> this was a swift operation from start to conclusion. within eight minutes of the first emergency call being received, officers deployed and neutralized the threats. that's an incredibly challenging and difficult situation. let's not forget when a phone call is made, the operator has to hear what's being said, understand it, type a message, communicate it to the nearest available crews who then have to get to the scene as swiftly as they can. make an assessment of what is actually taking place, identify the assailants, engage them and close them down. what we have seen is an

incredibly effective operation by these crews last night who deserve all credit for engaging in a very difficult situation swiftly. and the other point i think is worth bearing in mind is the facthat these individuals wore vests apparently pretending to be suicide vests which clearly to me seems designed to delay the attack, spread more fear and confusion, but the officers ignored that and quite properly engaged the threat and neutralized them so they could cause no more harm on the streets of london. >> we know the prime minister thanked them for their bravely. was the swiftness unusual or are they just getting better to responding to these attacks? >> i wouldn't say it was unusual or that it's getting better. this is what they're trained to do. we select the very best officers to go into this most demanding role and they're giving

incredibly good, world class training which is reviewed on a regular basis. they have to on a regular basis prove they're still up to the high standards required so that if something like this does happen, that the training kicks in automatically and they engage swiftly to respond. so that's what we have seen. it's been a work in progress, really, for the last sort of seven or eight years to continually look at threats that take place globally. we don't just look at what happened in the united kingdom, but globally, to the things that could potentially occur on our streets and make sure our officers are trained and equipped to respond accordingly. >> what are police likely doing right now? >> well, there's going to be a very extensive operation taking place now in a number of different aspects, the investigators will be looking to understand exactly who these terrorists are, who's in their network, if they're part of a

network, what's their association with friends and family, both in the united kingdom and globally, looking at social media connections. there will also be extensive work taking place to provide support and really difficult circumstances to the relatives of those who sadly lost their lives or were injured, and as we know, there's a very high number of those people, 48 people seriously injured in addition to the seven casualties. that's a large operation. plus, of course, all of the witnesses, hundreds, i would imagine, that need to be seen and interviewed to understand what's gone on. then, of course, there is the wider protective security operation, making sure that resources are out across the capitol. armed police officers. unarmed officers, all the appropriate merxs taken to try to safeguard the city and across the uk, i should imagine, as mest as the others are able to do. >> brian, so many people affected by this attack.

thank you so much for your time. >> thank you. abominable and cowardly, the words emanuel macron used to describe the attack. he expressed solidarity with the people of britain. christopher docky joins us from paris. thanks for joining us. this is the third attack in britain in three months. second on a bridge. and police say they have foiled other plots. why is the uk so heavily targeted? >> well, if you talk to french counterterrorism experts, they'll tell you a couple things. one is that it's gotten much harder to carry out terrorist attacks here in france. a number of them have been thwarted. there were terrible experiences here, november 2015, where the bataclan concert hall was hit and outdoor cafes were hit. we lost 130 people in those attacks.

we had the brussels attacks, the nice attack last summer on bastille day. since then, apparently, they have been able to crack some of the communications that are used by the terrorists and taken other measures here and made it much harder. the argument is or one of the things being argued is as it gets harder to attack in france, harder to attack in paris, you see the terrorists choses places where they have more freedom of operation. as great as the operations were taken down the terrorists in london last night, those were counterattacks after the incident had taken place, after a lot of people had been killed or wounded. now, more might have been killed and wounded had the special weapons teams not gone in to operation as quickly as they did, but the whole question is how do you stop this from happening in the first place? >> christopher, you mentioned that france had been targeted in europe. do you think this is a clear strategy by terrorist or random or maybe both to attack these

countries? >> well, dara, i think you put your finger on it, it's both. they look for targets of opportunity and look at where they're hitting. these are places that are almost impossible to defend. they're looking at beautiful places where people go to spend beautiful moments of their lives, weather they're walking across the bridgeoffs london or down on the sea side in bastille day celebrations in nice or going to a concert in paris or sitting in outdoor cafes. the point of these attacks is to tell people they can't lead their lives normally, they need to be terrorized all the time, and they're hitting the softest possible targets. how are you going to defend outdoor cafes in paris? how are you going to defend the open bridges of london? it's a very, very difficult job. >> if you could sum up security, what would be the one thing you would tell tourists traveling to those areas to pay attention to ? >> well, i think i would stay

out of crowds if possible. that's certainly a lesson of the moment. i would look for the kind of security that exists in the places you're going. i think the chances of you sitting in an outdoor cafe in paris or walking across a bridge in london these days and being the victim of a terrorist attack is very, very slight. but i do think that places where there are big crowds are a great target for terrorists. and not all those places are very secure. you see more and more barriers being put up here in paris, for instance, but in some rural venues in france, it may be dangerous, the same in britain. so stay out of crowds. >> christopher dickey, always a pleasure to have you here. thank you so punch. well, seven dead, dozens wounded after last night's attack in london. a look at what's being done right now to ease fears across the city.
