>> we have a fox alert on the investigation onto last night's terror attack it is not picking up speed. investigators looking to any possible overseas links and if the trio of attackers were simply radicalizing home. it is 10:00 p.m. reno in london. we are looking live almost 24 hours after this horrible terrorist attack. the streets now quiet and as you can see and security. united kingdom at this hour on edge after several major terrorist attack in the space of as many months. this is a brand-new hour of "america's news headquarters". >> the heart of london plunged into chaos sending terrified

people running for their lives. [video] >> it all started with a van running down pedestrians on london bridge. the three men inside the van then jumping out and going on a night rampage in an area packed with bars and restaurants. killing seven people, wounding dozens more. 21 of them are in critical condition.the three attackers were shot and killed by the police. a witness describes the task. >> i was thinking it was a fight. but i runaways is a manager in the door. when i opened the door i see three dead people. in the floor. >> mike is live in london with the latest. what do we know almost 24 i was later?

>> exactly about 20 rows and we know that ariana grande has returned to the stage in manchester. her fans shown out in great numbers. here in london a crime scene is still courted off. we have pictures now. this van was towed away a short time ago. please went slowly and methodically through the crime scene. the van just before 10 o'clock last night drove onto a sidewalk on london bridge ramming into a crowded pub goers. three attackers got out wearing fake suicide vests slashing their way through the crowd. within eight minutes police arrived on the scene and fired some 50 rounds unprecedented by british standards and then stop the attack. >> indeed i am not surprised that when faced with what they must have been with three suicide bombers, the firearms offices fired a unprecedented number of rounds to have complete confidence of the neutralized the rest of the men posed. i am humbled by the bravery of

an officer that rushed towards a potential suicide bomber thinking of only protecting others. >> seven victims are dead, 36 injured, 21 in critical condition.all three known attackers are dead.what is unknown is the amount of support they had pending the attack.police have conducted raids into neighborhoods in london. 12 people have been picked up in the raids. with the united kingdom having endured three attacks in three months, the prime minister theresa may has heard in her language related to radical islamic violence. >> we cannot allow this ideology the space it needs to breathe. that is precisely what the internet and the big companies that provide internet-based services provide. we need to work with allied democratic governments to reach international agreements that regulate cyberspace. to prevent the spread of extremists and terrorism planning.>> if you are not

near the crime scene in london you might not have known that there was an attack. the british people on a sunday were defiantly out on the seat at cafcs, at pubs, several of them think they change their lifestyle, then the terrorist someone. >> mike tobin, thank you very much. they are in london and mike is reporting there is more developing each hour as british counterterrorism authorities work to investigate those behind london terror attacks. we are live in washington where we are following the investigation. garrett, what can you tell us? >> british security sources are reporting the very early indications suggest that the attacks may have been put together on short notice. right now one of the top sent by say this could have been part of a larger plan additional attached to becoming. this is why they're now trying to learn as much as they can about the three attackers. they were, who do they communicate with and who if

anyone, help them carry out the attacks. >> where increasing confidence of the attack by three individuals. [inaudible] >> what the police chief is a leading to there is where these attackers inspired by the terrorist propaganda and acting alone for what a part of a larger self and acting the direction under a terrorist group? at this time, no group has claimed responsibility but counterterrorism analysts are pointing out that just before the attacks a message was posted that does call for muslims to kill christians during the holy month of ramadan using knives, guns and trucks. we do not know if there's any -- but they will get information off of cell phones wound on these men. today senator roy blunt to

regularly receives classified briefings divided the terrorist threat into two groups. isis style low-tech attacks with knives and vehicles and then the large-scale attacks such as those from al qaeda. on airplanes. >> i do think again that you have got some groups that are looking for a big player taking down an airliner. you have got others who need very little support, very little planning that can do incredible damage which is actually in many ways, almost more of a terrorism because you go anywhere, do anything you wonder what can happen at any moment. >> while the us remains under a constant threat of a terror attack the department of homeland security told us again today that at this time there is no specific credible threat of an attack here at home. >> that is good to hear. garrett tenney, thank you very much.

meanwhile after the third terror attack this year, the british prime minister theresa may is calling on allied governments to work together against extremism. the british leader is saying corporation is vital as she spoke only hours after last night's atrocity. >> this is as we all know, the third terrorist attack britain has experienced in the last three months. two weeks ago, the manchester arena was attacked at the same time. the security and intelligence agencies and police have disrupted five critical attacks. the recent attacks are not connected. but we believe we are experiencing a new trend in the threat we face. as terrorism breeds terrorism. >> join us now we have doctor ariel cohen senior fellow at the atlantic council. thank you for being here.

i want to start by getting your thoughts. what came to mind when you first heard the prime minister. she also said that britain is too tolerant of extremism. >> i agree with the prime minister. for an was the breeding ground for islamist most radical ideologies and organizations since 1990s. they tolerated way too long people who openly stated that they want to convert the british interior islam and impose -- for britain there were demonstrations in london i saw with my own eyes. i also advise the british muslim community which tried and failed to communicate to their government that they needed to tighten things up and prevent people flying in from the middle east, preachers to

plan for a weekend calling to kill christians and jews. i advised on measures with regards to the regulation of the mosques and the brits are very liberal. they are very fair people. and now they are reaping what they were selling in years past. >> prime minister amazing is comfort difficult conversations i'm asking how do you discard political correctness, face a furious and deadly problem that britain, us and other world leaders need to example and still not paid all modems with a broad brush? >> first what you are absolutely right. the majority of muslims are not extremists. and they shudder when they see what they are religionists are doing. but we would be expecting is more condemnation from the prominent members of the muslim community. both in the uk and here in the united states where instead, we have organizations like care

that are often whitewashing and advocating for terrorists. >> how would they be advocating for terrorists? >> they tried to explain ways some of the most heinous and extremist crimes that terrorists commit. and explain by oppression worth islamophobia and things like that. but back to britain and other european countries, first of all in europe, there is a breach in counterterrorism measures because what we see in britain is how the police work which is reactive, not preventive. what they need to do is much more prevention. much more intelligence work, domestic security work to identify the perpetrators but also the preachers, the recruiters.

the connections to isis, islamic state, al qaeda and other radical organizations. also, in europe major terrorist organization is not considered a terrorist organization because they are not -- in the european countries. >> let me jump in doctor because you're talking about proactive measures.the president believes the travel ban is just that. as you know many lower courts do not agree that a muslim man is the most effective appropriate for legal route to take. so how can the us effectively responsibly and boldly read the charge to conduct necessary and specific investigations and intelligence gathering to put a stop to extreme islamic terrorists?>> the united states right now is not the number one target in terms of terror attacks on our home

soil. europe is. europe was identified by the leaders of terrorist movements in the mid-2000 as a target for attacks. 500, close to 500, were murdered since 2014. worldwide by the way, the majority of terror attacks by radical islamists are against fellow muslims and the number for this year alone is 4500. 4500! >> doctor, listen, listen to the community, they attention, open your eyes. >> we need to cooperate not with just the democracies which mrs. may propose. we also need to cooperate with the middle eastern countries that have intelligence about these organizations.

>> are those countries comfortable what countries are we talking about? and are they willing to share intelligence?>> absolutely they're willing to share in the due cooperate. countries like egypt, morocco, gulf states, united arab emirates. and others. so we need the area expertise and the language expertise and also the islamic expertise. you need to work with moderate muslims to penetrate these organizations. so there is plenty of intelligence work but there is also a broader educational issue. we need to reach out proactively to the masses of muslim youth to explain to them that this is not the way to go. those who got that way will end up dead. >> doctor cohen, strong words. thank you very much. we will leave it there sir. thank you very much. >> meanwhile the easter season has come to a close on a pretty somber hour. pope francis praying for the

victim's of last night's terror attack. and his ceremony today. ariana grande is putting on a concert tonight. despite the horror last night she is sending a very powerful message of love and defiance. there are tens of thousands there along with her. while at home the president's travel ban is going to the supreme court. the president saying last night on twitter that this could help prevent similar terrorist tragedies from recovering here in our country. >> the president in the united states got elected to be president here first and abroad second. he is saying in reaction to what happened, it can happen here again. made with carbsteady to help minimize blood sugar spikes you can really feel it. glucerna. everyday progress.

supposed to help defuse the very types of tensions that can fuel international terrorism she says it is failing. we sent only last week she told me that if the council does not shape up, the us she says could ship out. >> you will be the first united states ambassador to the united nations to actually address the human rights council. why did you make this decision to go in person to see them based them down in person? >> and need to go to the human rights council. now we are looking at all of these areas where they have had human rights issues that have led to conflict. what we have seen in many of the cases of venezuela which is now an issue is when i brought it up in front of the security council. they said this should come in front of the rights council. while why did that happen? because venezuela's is on counsel. hugging every human rights council has venezuela in cuban on it? it just doesn't make sense.so we're going to go to geneva,

talk to them about what we think human rights council does well, talk to them on where improvement is needed and decide our status after that. to see if there really serious about human rights or not. >> do you have faith that i going there, by seeing them in person and by addressing this that it could change? >> i don't know that i will be successful but i know i have to have my voice heard. i know that they have to understand the us position and effectively take human rights very seriously. we think that it is the root cause of any conflict that can happen. and we expect certain things of the human rights council. and if they want to be better in if they want to make changes the us will stay on it. if they don't, then in the name of human rights, we will get off. >> the ambassador as you heard there made clear that if the council does not live up to its name the us will quit it. in 2006 under president george w. bush diaz did drop out and protest only to rejoin the council under president obama in 2009. was be described as moving

you guys made that decision. you look fear in the face and he said no, we are manchester and the world is watching. >> despite the attacks in london last night the show went on and ran into the concert singing over the rainbow in tears. all proceeds for tonight's concert will go directly to the victim's families. the number is expected to be in the millions. >> that is fantastic. i'm a big ariana grandes fan. the latest on the investigation on last night terror attacks to request law enforcement officials are stepping up security to protect travelers. this as you know the president and supporters have been worsening immigration policies of some british lawmakers. >> theresa may made a comment today that we need to have some

terror network either at home or overseas. the quiet tonight, a far cry from the time yesterday. [video] >> as you know seven innocent people were brutally killed. dozens more injured. many are in critical condition at this hour. the truck rammed the people on the bridge. then three of the terrorists we are told that jumped out and started stabbing people on the street. also in bars and restaurants. one dozen people are in custody for possible ties to the attack. they were arrested and taken into custody.one witness described the chaos. >> the taxidriver just swerved towards me and said ron, you have to run a have a knife! and i just started running. there were sirens everywhere.

people screaming. there was a guy injured and i tried to - >> now to our team coverage will is standing by at lax where airport security is being revved up. we begin with kristin fisher at the white house. as the trump administration keeps a close eye at the latest atrocity to hit great britain. >> this is the third time in less than a month that the president has had to put a british prime minister about a terror attack in her country. the two had just met 10 days ago at the nato summit in brussels to talk about the bombing in manchester. now this. now they're up in your suit. four of the us government and she is saying it is time to have some difficult and embarrassing conversations about islamist extremism. something that this sometimes

politically incorrect president has been calling for for some time. the president is a far less friendly relationship with london's mayor. this is first muslim mayor. we will explain why later today listen.>> is the guy that said that terrorist attacks are just partial with living in a big city. by the way it took six years to even mention islamic extremism, we are now, there are probably 20+ thousand people in europe that sympathizer's radical jihad is in. we are well beyond the end of conversation with the muslim community good is the counter insurgency right now. >> after the attack the mayor told his constituents that there is quote - no reason to be alarmed. a spokesman says he was simply urging londoners not to be alarmed when they saw more police. including armed officers on the streets. he is now accusing the president of deliberately misconstruing that remark in this to quote - at least seven day, 48 women in terror attacks and the mayor of london so

there's no reason to be alarmed. it appears the us embassy and london is now the same page as the president. the second most senior embassy official just praised the mayor on twitter saying i commend the strong leadership of the mayor of london. as he leaves the city forward after this heinous attack. now, president trump spent the day at a golf course in virginia and two sources on capitol hill are saying that he played golf with tennessee senator corker and peyton manning who plays football at the university of tennessee were played at the university of tennessee. he will be going back out again shortly to speak at an event in dc. the president could make his first full public remarks about this terror attack later tonight. >> if he does we will have it. for fisher thank you. >> we will await for remarks from the president later on today. he's already pointed to the importance of the travel ban.

this is law enforcement officials have stepped out security at airports, bridges and mass transit stations across the country. will is live at lax with the very latest on the measures being taken there. >> hi eric.through controversy and the report is the trump administration has maintained that the travel ban is all about keeping americans safe here with that in mind a short time after the attack in london yesterday because the president took to twitter tweeting we need to be smart vigilant and tough.you need to get back our rights. many of the travel ban as an extra level of safety. authorities in the both united states and europe are on high alert after a rush of terror attacks on soft targets but knew caused by the trump supporters for the supreme court immediately on the travel ban to go into effect. take a listen to the former deputy attorney general. >> the atmosphere can afford the court ruling things like this but i would look at this

and see the london bombings you know if there are actions taken in response to this, then you go back to the arguments with the lower court. have trump's ill advised campaign statements about muslims and about islam now tended everything he's going to do for all time? with respect to terrorist actions? >> at this point there is no timetable on when the supreme court may rule on the travel ban. it does come as authorities are asking for travelers to remain vigilant. take a listen to one flying from los angeles to london. >> in all honesty we have security mechanisms in place. so like i said you cannot live in fear. you have to live your life. >> that said, other passengers so that they do have real concerns about so many attacks in such a short amount of time. >> certainly understandable. thank you will. >> as we have been reporting the president hopping on twitter to share his opinions

of the london terror attacks. some are accusing him of using this strategy to score political points. is the president crossing the line? our next guest will discuss that with us. 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. if you have moderate to severe ulcerative colitis or crohn's, and your symptoms have left you with the same view, it may be time for a different perspective. if other treatments haven't worked well enough, ask your doctor about entyvio, the only biologic developed and approved just for uc and crohn's. entyvio works by focusing right in the gi-tract

headache and weakness. ready to let go of hep c? ask your hep c specialist about harvoni. >> they are finding new ways to disrupt us, harmonics, attack us. the police and experts in us are finding new ways to keep us safe. london has seen an increased police presence today and over the next couple of days. no reason to be alarmed. >> that is the london mayor on the terrorist attack that struck his city. in a treat -- in a tweet president trump said at least seven day of 48 wounded in the terror attack or the mayor of london says there is quote - no reason to be alarmed. what did the president mean? is he right or see way off?

we have a columnist for the national view. it has been pointed out that the term no reason to be alarmed, the mayor was referring to the armed police on the street. not necessarily the continued threat of terrorism. so what is the president of two? quest journalists, lots of people in public life sent out messages. the usually have fact checkers. by lisa somebody they show it to to say can you check this? the president apparently has no intermediary between himself and his tweets. this is an instance where he could have used one. >> to tell him know this is not a reference to terrorism. >> or how about the president just himself saying i will count to 10 before i send this out? >> there are potential tax and the whole issue. >> obviously there is reason to be alarmed because we have 3000 people in britain.

the vast majority of them muslims i terrorist watchlist for their behavior has extended her interest in law enforcement officials 24 hours a day. that is incredibly expensive. the reason why we cannot have more people monitored that way is because it's so expensive. my proposal is if you are a noncitizen britain you are there is a privilege, not as a right. they can be deported. because obviously behavior is that they are being watched 24 hours a day. >> the numbers are standing here today hundred 50 came from syria libya 850, the 3000 on the watchlist and 23,000 according to the times of london. people who are potentially sympathetic. i mean that's just - >> accomplices. >> is there any way for western societies to get a handle on this? it has been suggested that perhaps those for some among them should be potentially detained temporarily. is that impossible

constitutional or legal? >> they do not have a constitution. they have a common law. so they can pretty much do whatever they want. i think if you are noncitizen of britain, you do not have a right to be in the country. and frankly, we can probably watch all of the terrorist suspects if we simply deployed the noncitizens or lisa started to move towards her. were they have to come up with in its place why they need to stay in britain.>> what about people on the watchlist? we have potential suspects. there have been operations ongoing right now. what should we do? >> i believe less of a problem in britain because of better ports -- our muslim community in this country is far more in agreement than the one that britain has. having said that though there are still homegrown terrorists in this country. if they are native born obviously that full constitutional rights.

if they are not native born that we have a conversation with them and perhaps we -- if you are a citizen you do not have the right to be here automatically.>> we have to be charged or convicted of a crime before they take action. because of civil liberties. quickly we have a green card here that's a privilege. if you're here is a student and you arouse suspicion that can be revoked. if you're here on a visa and have committed a crime, it means you can be deported. >> you think we have been not tough enough? >> clearly we have not been tough enough! something like 40,000 people have rated serious crimes in this country. they were released from jail than last year and 1/2. they did not go to the ins. they did not see i.c.e., they basically walked out on the street. they should have been sent to a center or at least they would have been processed and interviewed. potentially sent back to the country of origin.

>> the president in a tweet blames political correctness. he says quote - we will stop being politically correct and get down to the business of security for our people. if we do not get smart it will only get worse. we talk about let's say kicking somebody out, on suspicions of terrorism and it is not happening now. apparently. >> no, and i do not suggest it should happen for citizens. certainly the president has been very ham-fisted about dealing with this. most of the travel ban's have serious problems with them. i think the supreme court will eventually declare a constitutional. the president has done damage by the way he is going about handling this. he certainly created an impression even though it may not be true that he is anti-muslim. >> despite that what you think he should do quickly to try and get a handle on terrorist activities in this country? >> we need to have much better coordination with countries. we need to regardless of whether or not there are

discussions on this we need to have much better discussion with our neighbors especially mexico and especially central american countries about people slipping through here. because it is pretty easy for someone who is not mexican or el salvador in to somehow get to those countries and slip them into this country. >> means the threat is continuing, it has been here for decades. it was good to see. >> thank you. investigators facing arrest and continuing to conduct searches after last night's deadly terror attack in the heart of london. what exactly are they looking for? up next, a closer look at the search for clues. >> the police are doing two things. they will be looking at in-depth forensic examinations so they can know exactly what happened last night. they will also urgently trying to establish the identity of those involved. ...i learned humira is for people who still have symptoms of moderate to severe crohn's disease... ...even after trying other medications.

in clinical studies,... the majority of people on humira... saw significant symptom relief... ...and many achieved remission. humira can lower your ability... ...to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened;... ...as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where... ...certain fungal infections are common, and if you've had tb,... ...hepatitis b, are prone to infections,... ...or have flu-like symptoms or sores. don't start humira if you have an infection. just managing your symptoms? ask your gastroenterologist about humira. with humira, remission is possible. >> the time now for a check of

the headlines. police are bracing for possible unrest. anti-trumpet rallies are taking place. hundreds of protesters on both sides yelling at each other. but so far it appears to be it. and james mattis, there is allies to do more for their self-defense. saying it can help provide peace and stability in the region.

the pentagon -- pope francis offering prayers for victims and families of last night terrorist attack in london. the holy father apparently at st. peter's basilica for pentecost marking the official end of the easter season. we continue now with our top story is where just getting information that isis has claimed responsibility to the attack here this as investigations continue in london after the horror scene there. or 30s rating buildings and homes in the eastern part of the city and investigators saying they are focused on attackers that were shot and killed by police. >> work is ongoing to understand more about them. and whether or not they were supported by anyone else. as i think you are wearing their research is ongoing in east london and 12 arrests have already been made. there is plenty more to do.

we will do it relentlessly to get to the facts. >> we are joined now by the former fbi deputy assistant director and the fbi hostage rescue team commander. danny, will start with the white man. what cannot tell investigators, fingerprints, credit card records, if it was rented? also what about the nouns and suspects and also the breaking news that isis is now claiming responsibility for the attack? >> as well, the band can be a treasure trove of insulation. not just friends but also dna. this can be a lot of dna evidence in there. you cannot go any place to rent a car or van and not leave your dna. that can be really good. what is going to happen in the investigation is there are apps out there i think the prime minister talked about it today. that intelligence services, law enforcement cannot get into. so these guys have communication network that cannot be penetrated by the fbi. or anybody else. the parliament need to take a

look at that. congress needs to take a look at it. once these things happen or even prior to their happening, there is a way to see what these guys are doing. and maybe prevent the series attack like this. >> absolutely. as i said breaking news is that isis is responsibility for the attack. one is that children analysis of what happened there? >> he really doesn't. it doesn't matter whether it was isis directed arises inspired. they are both the same. it doesn't really make it different. what you want to do is get this tangled web of cells over there so that you can keep these things from happening in the future and it will be difficult. scotland yard is very good. i've done a lot of work over there. have a great deal of capabilities and they are tenacious. and it is a big job and with the threat that they are facing, the probably need more resources than they have right now.

>> and there are no go zones they just referred to. let me talk about this. >> i was going to say, they need to eliminate those things. if you have law enforcement presence coming of the ability to help sources, information and maybe stop these things. but this no go, they need to change that. they need the fas to go in there and clean them out. law enforcement needs to be there. it is called when we have a civilized culture. no society can sustain that. >> a pulitzer prize-winning journalist and also fox news analyst wrote a piece for the fox news .com opinion. she was applauding the response of the work of the british police. saying quote - important steps of intelligence and security fastness and adherence to our own corps of values. make no mistake london bridge will not be the last attack in england or europe or the us.

so do you agree with her take and how do london, metropolitan police, nypd, intelligence agencies work to thwart future attempts of these smaller scales but deadly attacks? >> i totally agree with what she said. they don't have a constitution but they have a law. but they should observe the law. but one of the things you start with very frankly is arming their policeman. we've seen throughout europe, belgium, france, and now england where police men as they are they are unarmed. that makes them trying to do their job with actually no protection. they need to start with that. arm there police and then let them have what they need to go after these guys. remember, this is not a bank robbery. this is a tsunami effort to take over the world for these guys. they want to establish a law through the world and it is

called war. we need to address this as we are doing. >> also she went on to say that there will be no more endless debates about the motives and nature of this the attackers yelled this is for a law. and they shouted in english. there is such conviction, is this vital to combat terrorism as a minister theresa may their brand thing that is time for difficult conversations. how much quickly as you could how much it is impede intelligence agencies? >> i think very much so. we cannot do this and not call it what it is. it is war. and when they say they're at war with us maybe we will wake up one day, the leaders will wake up one day and say you are right, this is war and let's treat it like it is worth. >> we will leave it there thank you for your time. >> thank you it is always a

pleasure. >> investigation in england and testifies of his hours. up next, how london is honoring the victim's of this latest attack. made specifically for indoor cats. purina cat chow. nutrition to build better lives.
