Pop star is headlining that concert today. Connect americas news headquarters from washington begins now. Nice to be with you at home. Im leland im elizabeth prann. Partly sunny which normally airs at this hour can be seen tonight at 10 00 p. M. And again at 2 00 a. M. Eastern. The police in london say they are making significant progress in tracking down the identities of three attackers who killed at least seven people and injured dozens more. David lee muller is live in london with the very latest. Reporter elizabeth, londoners are being told they should remain calm but vigilant and this in the wake of the terror attacks that killed at least seven people, wounded as many as 48, 21 we are told quickly. The attackers plowed a van, white man into pedestrians on London Bridge and then attempted to stab anyone nearby. All three attackers were killed in a hail of bullets. Please fired as many as 50 rounds fearful that the suicide belt, now determined to has been safe but could have been the real thing. Indeed, i am not surprised that one face with what they must have feared was suicide bombers that the officers fired an impressive number of rounds to the complete confidence that you neutralized the threat that was been imposed. I am humbled by the bravery of the officers was rushed toward potential suicide bombers thinking only of protecting others five authorities tried to identify the computers they keep evidence in the police that the white van was used to create the carnage. It was rented according to authorities by one of the attackers. Authorities not commenting on what, if any, evidence that van might contain insight. The question now on the minds of so many here in london and throughout the uk and beyond, did the attacker receive any help. Today in a series of raids in east london, 12 people were arrested in connection with this ongoing investigation. Adding to the tension here, lupus, later this week on thursday the uk voters will go to the polls for a national election. Elizabeth six david, thank you so much. Five catherine herridge, great to have you. Give us a sense. What do we know . Connect no group right now is claiming responsibility but within minutes of the attack the senior isis affiliated social media account pushed out propaganda on using vehicles as weapons, threatening even more violence. Its not clear from our reporting whether it was opportunistic or the terror group played a role. British Security Forces say early indications suggest the attack may have been put together as short notice. Us and uk intelligence are focused on the suspects and whether they act alone or added a Terror Network behind them. In addition, were increasingly confident that this attack was conducted by three individuals, clearly, we need to establish whether associates or were involved in the planning. Elizabeth there flagging a message posted just before the attack in pro isis telegram calling for lone wolf plots during the month of ramadan but again no evidence, yet, showing they are connected. A lot of that will be known to the forensic review of the suspects electronics. On Fox News Sunday, this morning, republican on the Senate Intelligence committee gets regular classified briefings broke down the fat into two groups. Isis that purchase lowtech attacks and al qaeda the remains focused on commercial jets. I do think again that you have some groups that are looking at a big play like taking down an airliner, you have others who lead very little support, very little telling and can do incredible damage which is actually, in many ways, almost more of a terrorism because you go anywhere, do anything, you wonder what could happen at any moment. Questions are being raised about a possible intelligence failure after the British Government recently lowered the threat level in the country. Leland a couple things, kevin. What we know about the state suicide vest . I spoke with the analyst made two valid points about the best. Number one is that from a distance and in a chaotic situation the civilian who were at the site would see them as a real and make them intimidated and not trying take on the attackers. For the police came in with weapons from a distance, it looks like the real thing, and they would shoot to kill. This was seen by my contact is more evident that the three suspects intentionally sought to be martyred in this case. Leland fascinating. The big issue in light of the manchester was the intelligence sharing between the uk and us. The brits were upset about the leaks on the side of the pond on their most sacred intelligence. Are they still worried . Are they sharing as much United States respect for that matter, are your more so scared to talk. I would say that the british had been much more on close hold with the information in light of what happened in manchester because the release of the suspects name really disrupted the effectiveness of the british investigation. Once the name is out there, everyones running the individual, and the network really can go to ground. It is important to know that we are almost 24 is after the attack and the british know these guys are. Okay . For sure. The reason we dont know is because theyre being very close hold on the information. Leland so far, there than all the rest. We saw this dragnet roundup if you will. People were released and they were charged and thats probably what happening here . What i would tell you in terms of my experience is that just because someone picked up and released doesnt mean that theyre in the clear. In fact, its a triedandtrue strategy to pick people up to do a scrub of their electronics to capture everything on their phone in the computers or ipads and then you let them go and see if they go to next. Its really a cat and mouse situation. Leland it goes back to your point here on how it is important to keep the names secret. It was devastating when it name linked five these names have. Kevin, thank you. Come back as you learn more. Elizabeth. Elizabeth the white house is keeping a development weve heard from president on twitter. Hi kristin. The president is continuing to receive updates from his National Security council. Hes offering the british Prime Minister the full support of the Us Government and hes continuing to push two things were absolutely central to his campaign. Now, his presidency. Extreme extreme betting and ending the political quickness. We must stop being politically correct and get down to the business of security for our people. If we dont get smart, it will only get worse. Thats similar to what british Prime Minister teresa mate said earlier today when she spoke out that its time if not past time to have some difficult conversations. Mike huckabee drove at home in an interview earlier today on fox. When teresa may made the comment that we needed to have some embarrassing conversations with that they had open borders for so long and now they act their socks that people have come into the open doors and windows and are killing them. If you keep getting hurt by mosquito bites at some point you decide to start killing mosquitoes. The president is hoping to keep the wrong people from coming in the open doors and windows. This is betting. Its been blocked repeatedly in court but the Trump Administration has dropped up the Court High Court to reinstate the democrats including National Susan rice hit the sunday shows that they believe a ten travel ban will not make the us safer. Theres a very real risk that by stigmatizing and isolating muslims from particular countries and muslims in general that we alienate the very communities here in the United States whose cooperation we most need to detect and prevent these homegrown extremists from being able to carry out attacks. Elizabeth president clearly disagrees. He believes that the travel ban is needed now more than ever and that what is happened in london only proves that. Liz. Elizabeth , thank you so much. Five live pictures now from london where it is almost fun down there for four hours or so, a little less, then her this attack started. Youre looking at the van in question and you can see forensic teams going through that band. They are now waiting to take it away from what will obviously be exhaustive analysis, according to the police, the van was recently rented by one of the attackers. Little more analysis while watching london bring in Robert Driscoll, former Deputy Assistant attorney general. Good to see if want to bring a petite from president that went out a couple of hours ago. We must stop being politically correct and get down to the business of security for our people if we dont get smart, it will only get worse. It brings up an important big picture questions. What more can be done under the headline of getting smart while still being for lack of a better question, constitutional . Theres lots that can be done. Certainly, theres lots to be done for existing laws and you lost can be passed. As long as they dont violate the constitution. Leland what new laws do we want to spark. Ice expect what they want is the cyber area where they could use some better amendments to have better ability to go after terrorists. Then you running up against privacy how many do you pick up on civilians. I suspect this gets into issues of religious and ethnic profiling and whether or not how far the government can go in terms of using those criteria as factors in terms of picking up they want to avail. Leland the british obviously were going to pick up a number of those devices that not only belong to the suspect but they must have left inside the van and inside their apartment but also their friends pull all those guys into the dragnet, scrub devices and send them back out into the real world. Its times like this, first 24 hours, does the us law agencies have the same rights as mark or can the british go farther than we can. I understand they can go a little farther. They dont have the same constitutions protections that we have. Its good that were americans that have those protections. They protect everybody. Sometimes it is easy to get envious when theres an International Incident and you see, boy, jordan can get after these fellows but you have to be careful about doing that. I think, but it always whenever theres an incident encourages people to look at how far the constitution does allow us to go, whether were going against the constitution or whether or not our existing laws to be amended in some way. Leland can as we learn with and its a civilians there are things within the gray area of the laws that are simply kept secret. You brought up the issue of racial profiling and it became a religious profiling which became a big factor in present times travel ban. He tweeted out this last night. We need to be smart, vigilant and tough. We need the court to give us back our rights, we need the travel ban as an extra level of safety. That travel ban, as we talked what you say, goes before the Supreme Court. Does these additional attacks change the dynamic of the argument . It shouldnt actually because its no indication that the six countries involved were involved. But the whole situation, the atmosphere can affect courts rulings and things like that. I would look at this and see the london bombing if there are actions taken in response to this you go back to the arguments to the lower court. Have the trumps illadvised campaign statements about muslims and about islam now tainted everything hes going to do for all time with respect to terrorist actions for the next action will be invalid because of what he said . Leland though campaign statements tie his hands as the executive, no matter what. If one follows the logic that the courts are to follow which is being appealed to this report that this type of situation might force the court to look and say, wow, what would be saying if we adopt the laws of the lower court. Even new measures taken by the newer government would possibly be at risk. Leland as he went up yesterday, very astutely, the issue that even those against the van and headband that this travel ban have been enacted by another president and he didnt make this comment he would have a leg to stand on. Exactly. Leland thanks for your insight. Liz was coming up. Elizabeth heavy security in manchester where the victors of last month terror attack where superstars are having a concert.

Elizabeth theresa may spoke to the world about the attack. The third deadly assault in the United Kingdom since march. Prime minister mae says terrorism breeds terrorism and now is the time for the west to make major changes on the war on terror. Here she is laying out her plan going forward. We cannot and must not pretend that things can continue as they are. Things need to change and they need to change in the four important ways. First, while the recent attacks are not connected by common networks, they are connected in one important sense. They are bound together by the single, evil ideology of islamist extremism that preaches hatred, close division, and promotes secretary. It is an ideology that claims our western values of freedom, democracy and human rights are incompatible with the religion of islam. It is an ideology that is up version of islam and a perversion of the truth. Defeating this ideology is one of the great challenges of our time. It cannot be defeated through military intervention alone. It will not be defeated through the maintenance of a permanent, defensive, counterterrorism operation. However skillful if leaders and practitioners. It will only be defeated when we turn peoples minds away from this violence and make them understand that our values, british values, are superior to anything offered by the preachers and supporters of hate. Second, we cannot allow this ideology of the state space it needs to breathe. Yet, that is precisely what the internet and the Big Companies that provide Internet Based Services provide. We need to work with allies, democratic governments, to Reach International agreements that regulate cyberspace, to prevent the spread of extremism and terrorism planning and we need to do everything we can at home to reduce the risks of extremism online. Third, while we need to deprive the extremists of their safe spaces online, we must not forget about the safe spaces that continue to exist in the real world. Yes, that means taking military action to destroy isis in iraq and syria but it also means taking action here at home. While we have made significant progress in recent years, there is to be frank, far too much tolerance of extremism in our country. So, we need to be, far more robust in identifying it and stepping it out across the Public Sector and across society. That will require some difficult and often embarrassing conversation but the whole of our country needs to come together to take on this extremism and we need to live our lives, not in a series of separated segregated communities, but as one of truly United Kingdom. Fourth, we have a robust counterterrorism strategy that has proved successful over many years but as the nature of the threats we face become more complex, more fragmented, more hidden, especially on the strategy needs to keep up. In light of what we are learning about the changing threat, we need to review written counterterrorism strategy to make sure that the Security Services have all the powers they need. If we need to increase the length of custodial sentences for terrorism related offenses, even apparently less serious offenses, that is what we will do. Since the emergence of the threat from islamic inspired terrorism, our country has made significant progress in disrupting pots and protecting the public. But it is time to say, enough is enough. Everybody needs to go about their lives as they normally would. Our society should continue to function in accordance with our values but when it comes to taking on extremism and terrorism, things need to change. As a mark of respect, two Political Parties are suspended our National Campaign today. Violence can never be allowed to disrupt the democratic process. So, those campaigns will resume in full tomorrow and the general election will go ahead, as planned, on thursday. As a country, our response must be what it always has been when we have been confronted by violence. We must come together and we must pull together and united, we will take on and defeat our enemies five Prime Minister teresa made speaking out of ten downing street this morning. Right now, 200 miles to the north of london, like pictures coming in from whats called Manchester United stadium in manchester. The soccer team they are, 7 23 p. M. And there is a huge concert going on for american pop star ariana conde. It was just after her concert 13 days ago that a suicide bomber blew himself up into the lives of more than 20 of her fans as we have been reporting, many of them were children. She is back on the state in manchester, unafraid she says and the entire city of manchester saying there unafraid and defiant as well. Brian, following the story is the british once again are forced to say we will not surrender. Brian. Reporter exactly right, leland. The concert is just getting underway
