The British Police say they know the names of all of the terrorists that went on a ram pain in london saturday night ramming their van into a bunch of people on the London Bridge before going on a stabbing spree at the borough market. So far they released the names of two of the suspects. One is a british citizen that lived in the area. Police say the other lived in the area and theres conflicting reports on age and nationality. Shortly after the attack, police shot and killed these two men and a third man whose name they have not made public. The killers were wearing fake suicide vests. Police say knew about butt before the attack. He had been reported to have terrorized himself but he was nod planning anything before the brutal attack that killed seven and injured 48 others. Isis has claimed responsibility. Saturday was the third terrorist attack in england since march. Today the british Prime Minister, tereheresa may says i time to change our approach to terrorism. We cannot go on as we are. Enough is enough. We must do more, much more to take on and defeat the evil ideology of islamic extremism. Its an ideology that promotes a choice between our western values of freedom, democracy and human rights and the religion of islam. Shepard police say Counter Terrorism investigators searched two homes and detained what they called a number of people suspected to have some sort of connection to the terrorists. Over the weekend, police say they arrested a dozen people. 11 of them are said to be in custody. This is christine archibald. She moved to europe to be with her fiance. Relatives say she was one of the people whom the terrorists mowed down with their van. Local newspapers have identified a french man who reportedly died after one of the attackers stormed the restaurant where he worked. This was near the scene of the attack. Start it back at the beginning. This was at the scene of the attack near today near London Bridge. This is the response to the attack over the weekend. Crews have installed large concrete barriers. We were there a few weeks ago. This is brand new. Theres Westminster Bridge where the five people died in a car and knife attack in march. This is near londons market with people marching, turntolove. You can see commuters on their way to work. This is the scene of one of the houses where Police Conducted raids less than 24 hours after the attack. A starstudded benefit concert took place about 150 miles to the north in manchester. It was two weeks ago a bombing at an Ariana Grande concert killed 22 and injured children. Last nights local time concert featured artists including black eyed peas, katy perry, miley cyrus and Ariana Grande that headlined the event and organized it. According to the british red cross, the concert raised more than 13 million. The Prime Minister may said that britains Terror Threat level will remain at serious, which means an attack is highly likely. Thats one step below the highest level, which is critical. We have team fox coverage. Catherine herridge live in washington this afternoon. First, to mike tobin who is live just after 8 00 p. M. What are we learning about the attackers . Investigators cant pin down one of the terrorists. Koram butt was on the radar of police and mi 5 since 2015 because he spouted off about radical ideology. Theres reports that he tried to recruit children nor isis. The raids have been taking place in a borough called barking. A dozen people were picked up. One was released quickly. So from the information that we have thus far, police are Holding Around 11 people believing theres a Larger Network of assistants or sympathizers. Scotland yard pleading with the Muslim Community for more information. Shep . Shepard what is the situation like on the ground there . You have a city that wants to mourn. Thousands came out to an area called pottersfield for a vigil today. A very emotional testimony. The mayor criticized radical islamists. He himself a muslim and he said the radicals are ruining their religion. We thank our courageous Emergency Services and the brave londoners that risked their lives to care for others. You are the best of us. And politics is back in full swing. The prime candidates were supposed to take a day off yesterday. They never really died. Prime minister theresa may and Jeremy Corbyn have been taking jabs to each other as it relates to the tabs of undercutting police financially. Shepard thanks. Catherine herridge is live now with more on the investigation from washington. Catherine . Isis claiming responsibility but its not clear from our reporting whether the claim is opportunistic or the terror group played a role in training and the operations. A message posted just before the attack to pro isis channels on telegram calling for lone wolf attacks during the holy month of ramahadan. Its important to note the method of attack in this last case with the vehicular attack and the knifing. This is classic. It goes back to lee rigby, the british soldier that was almost beheaded on the streets. Weve seen more in israel, this is the classic tactics of the global jihadi threat. Five plots have been discovered since the manchester attack. And what else is attracting the attention of investigators here . Our attention is being drawn to images with suspects with canisters strapped to their bodies that looked like suicide vests. This is to guarantee martyrdom because police are told to kill, not negotiate. A republican member of the Homeland Security said the fbi and local police in this country should use the same approach. That seemed to have positive results and tackled mob crime. You have to have infiltration and surveillance. You can have all the security in the world. If the security shows up after the fact, the lives have been lost already. U. S. Government officials told fox over the weekend they had viewed some of the classified intelligence and describing what they saw as some of most severe threats that theyve seen in the last decade, shep. Shepard thanks, catherine herridge. Lets turn to tara maller. Shes a spokesperson and senior adviser. Great to see you,tara. Thanks for having me. What jumps out at you here . What jumps out, we dont know a lot about these individuals. We have a sense that one was on Law Enforcements radar screen but were not sure if they had contact with isis or another terrorist organization. Were not sure about foreign travel. Were not sure about other associates or if this was part of a larger cell in the u. K. A lot of factors here that could have contributed to the timing. Isis has been calling for attacks in ramadan, calling for vehicles attacks in the ramadan season. We just saw that ham on the heels of two other terrorist attacks in the u. K. So while its tragic, its not surprising given that weve seen a buildup leading up to this attack. Still a lot of questions about the level of contact these individuals may have had. If one was on Law Enforcements radar, were there flags that were missed ahead of the attacks. Shepard we take about Law Enforcement radar. Its one thing to say that in the United States. Over there, theyre said to have 20,000 separate individuals on watch lists. In addition to that, what is it . 5,000 open investigative cases . There i believe under mi 5 about 500 active investigations. A couple thousand suspects associated that are being looked at in conjunction with those. Youre correct about the 21,000 overall. So its a lot of individuals that are being sort of watched, monitored on the radar screen. Obviously they need to prioritize these cases. So while this individual may have been on the radar screen, i believe it was for reports from friends about him viewing extremist content online and potentially seeing signs of radicalization, which is critical here. There was mention a lot of what he was being reported for is online activities, which goes to the point that Prime Minister made about the Technology Companies need to crack down on this. Its a Common Thread across all of these cases. Shepard these low tech attacks, theyre much harder for investigators for obvious reasons. But youve said theres still ways to make these sorts of operations more difficult to carry out and easier to investigate. There are. While a low sophistication attack involving knives and a car is more difficult than a highly sophisticated attack involving financing, communications and materials, theres still ways to educate the public to remain vigilant. Things that Law Enforcement can do to spot the signs and also steps to take to try to thwart these when early signs of radicalization may be seen. In this case, a friend reported suspicious activities. Things that companies can do. Theres Technology Available that can get this content off twitter and facebook and social media. The Tech Companies have been ramping up their efforts but theres a lot more that could be done if they wanted to clean up their platforms. A lot of these individuals view the same content that remains on the same platform. In this case, it was a particular extremist out of deer born, michigan, whose videos are online and extreme in nature. So theyre looking at the same material over and over again and this ought to be taken down. And lastly, at the actual time that the attack happens, you really want to make sure that people know what to do in these types of emergency situations. Tara maller with us from washington. Thanks, tara. Thank you. Shepard President Trump tweeting again about the attack and pushing his travel ban. Hes now going after his own Justice Department. In other words, his own employees saying the ban, its taking to the Supreme Court doesnt go far enough and he signed it. Have you seen the tweets from the husband of one was president top aides . Breaking in the last hour, no executive privilege to be exerted. The white house has decided the president wont try to stop james comey from publicly testifying about the russia investigation. So its on. This thursday. Thats coming up from the fox news deck on a monday afternoon. This is me when i feel controlled by frequent, unpredictable abdominal pain or discomfort and diarrhea. I tried Lifestyle Changes and overthecounter treatments, but my symptoms keep coming back. It turns out i have Irritable Bowel Syndrome with diarrhea, or ibsd. A condition thats really frustrating. Thats why i talked to my doctor about viberzi. A different way to treat ibsd. Viberzi is a Prescription Medication you take every day that helps proactively manage both abdominal pain and diarrhea at the same time. So i can stay ahead of my symptoms. Viberzi can cause new or worsening abdominal pain. Do not take viberzi if you have no gallbladder, have pancreas or severe liver problems, problems with alcohol abuse, longlasting or severe constipation, or a bowel or gallbladder blockage. Pancreatitis may occur and can lead to hospitalization and death. If you are taking viberzi, you should not take medicines that cause constipation. The most common side effects of viberzi include constipation, nausea, and abdominal pain. Stay ahead of ibsd with viberzi. Shepard theres breaking news now on fox news channel. The president will not try to stop the former fbi director james comey from testifying about team trump ties to russia and his conversations with the president before the president fired him. Thats the word from Sarah Huckabee sanders. James comey is set to testify this thursday before the Senate Intelligence committee. All of this after sources close to comey said President Trump asked him to stop investigating michael flynn. President trump fired director comey last night and later admitted that the russia investigation was on his mind when he made that decision. Chief White House Correspondent john roberts live on the north lawn. A lot of wagering whether the white house would allow comey to testify or whether they would invoke executive privilege and prevent him from testifying. It probably would have been a conversation covered by executive privilege but enforcing it might have been difficult. Its possible the president could have done it had he wanted to do. As we opened the briefing, a question i asked Sarah Huckabee sanders evoked a final answer. Hes scheduled to testify thursday. Theres a question as to whether or not you will invoke executive privilege or if you will allow him to testify. The president s power to exert executive privilege is very established however, in order to facilitate a swift and thorough examination of the facts sought by the Senate Intelligence committee, the president will not assert the executive privilege. Had he done it, the president would not have been the first to invoke executive privilege. President obama did it regarding documents concerning the fast and furious scandal. President clinton tried, but failed to do it during the lewinsky sandal. He tried to prevent his aides from testifying. He took it to court and lost, which is something no president ever wants to do. But looking like thursday is a very big moment here in washington. Probably across the country as well, a lot of people tuning in for that. Shepard yep. Beginning 10 00 a. M.

The president lashed out at his own court system and the Justice Department two days after the latest deadly terror attack in london. He tweeted people, the lawyers and the courts can call it whatever they want but im calling it what we need and what it is. A travel ban. The Justice Department should have stayed with the original travel ban, not the watered down politically correct version they submitted to the Supreme Court. The Justice Department should ask for an expedited hearing. Were extreme vetting people coming into the United States in order to keep our country safe. The courts are slow and political he says. Of course, he signed this order that he now calls watered down. He signed it. Its an executive order. Federal courts have blocked the president s revised travel ban and the original version which he signed off the inauguration. The trump filed an emergency request with the Supreme Court asking it to immediately reinstate the advised ban. The administration asked the Supreme Court to take up the travel ban in the fall. Under this revised plan, the one the president calls the watered down version, the government would ban refugees from all countries from entering the United States for four months and block visitors from six muslim majority countries for 90 days. Lawyers challenging the president s travel orders say it discriminates against muslims and most courts have agreed. Candidate trump called for a muslim bam during the campaign but the administrations lawyers have said they should ignore those comments and look at the executive order itself. Some analysts say the term travel ban raises legal problems. Several judges have cited the phrase like the one he used today in their information to block the order. The president said it is a travel ban. In fact, today the president tweeted the measure is a travel ban. Some of the analysts say the president s tweets today may have undermined his own legal defense. The husband of President Trumps counselor, Kellyanne Conway, criticized the president s tweets. George conway said the tweets may make some people feel better but wont help the office of the solicitor general get five votes in the Supreme Court, which is what matters. Sad. George conway just last week with drew from consideration to be the president s nominee to reason the Justice D
