They took the shot. Another official tells cnn emwazi was in a vehicle near raqqa. Emwazi appeared in a series of isis beheading videos, documenting the murders of several murder, american and britain japanese hostages, he was seen taunting u. S. And british leaders. Well continue to strike the necks of our people were this morning, the uk government saying britain was working hand in glove with america over the jihadi john drone strike. This was an act of selfdefense, the right thing to do. Reporter emwazi, in in his mid20s. If this strike was successful and we still await confirmation of that, it will be a strike at the heart of isil. Reporter one of the things that he also said was that this was a longterm operation of the two Intelligence Services and also said this is a clear message to isis as well that the reach of the u. S. And britain is long and that they will not forget the fate of their citizens. All right, fred, thank you for that. Meanwhile, day two of operation free sinjar. Thousands of Kurdish Forces storming the city with u. S. And coalition warplanes, providing cover from above. A defining moment in the war on terror. Lets get the latest on the offensive from cnns Senior International correspondent Nick Paton Walsh, live in sinjar. Reporter in the distance behind me you can see a grain silo which was, were told, one of isiss main buildings in sinjar. Now its in the hands of the kurds. Theres been a substantial change in sinjar since this morning. We saw earlier on today large numbers of peshmerga troops moving in on foot, walking down the roads, converging in the city center. Then intense clashes, they careerly ran across isis and certain pockets there. Those clashes continued. We eventually joined the peshmerga down on the street level, down there you can see the intense damage inflicted on that city, both by Coalition Air strikes but isis suicide bombers as well. So little left to go back to for the yazidi population. So many booby traps left at the side of the road. We heard from a volunteer, jason, working as a medic and seeing kurds die right in front of him during this brutal fight, there are over a dozen hed seen just in the previous few hours. Its frankly a death trap at this stage. The guns have fallen silent behind me now. There may still be isis inside the city. There may be booby traps still. The question is how swift has the victory been, and when can the yazidis move back to their town of sinjar. We want to bring in Lieutenant General mark hertling. Good morning, general. Great to see you this morning. Lets talk about this air strike that possibly got jihadi john which we know well from the sinister beheading videos. What would the significant be . The significance is theres increasing amounts of intelligence that allows forces to, toette hill. Thats the most important thing in my mine. Youre talking about a city that has been held by isis for over a year now. And they have had control of that city. Weve had very little intelligence inside the city. We are increasingly able to get that based on partnering and engagements with not only syrian arabs but also the Kurdish Peshmerga in that area. The targeting piece of this, the ability to actually strike something with a level of confidence, thats a tough process to go through. Ive run targeting cells in the past. When you get that level of confidence and intelligence on a target in a city that you dont have control of, its pretty important. But, general, in terms of loss to isis of jihadi john, this would be a symbolic victory. Everyone wants to get the man behind these sickening videos. Cant isis just find another person to fulfill that role . They certainly can, alisyn but the key point is, it tells isis we have the ability to target them wherever they are. Thats important. Yes, its important to get the guy who was on the video, whos a brutal murderer and seems to be a little bit sadistic from all reports but it is also important to let them know youre not free to move around. Were seeing increasing evidence of that throughout the campaign. As more intelligence comes in, as we get the feet up under us, we can go anywhere we want and strike these targets. This will make the other people in raqqa that are defending isis there a little bit concerned about their safety and it will cause them to change their pattern of life. General, as we speak theres a battle under way for sinjar. Youve spent a lot of time there. I want you to walk us through whats happening. Heres the map and this is the red is whats under isis control. You see sinjar. The yellow is isis support zone, the orange is isis attack zone. Tell us what you see with these tentacles. Yes, thats a great map, alisyn. It shows you that isis has been occupying areas is lock a Logistics Supply line to mos. If you draw a direct line of isis to raqqa, it will go through sinjar and telafar. Thats how they reinforce mosul with fighters and supplies. In the other areas, what youre talking about is the flow down the euphrates and tigris rivers. Thats where the main cities are. Thats where you have People Living because they use the waters off those two rivers to cultivate their crops and to basically its the life spring of the country. When youre talking about controlling the cities along those rivers, you also control a lot of other things. Thats what were attempting to break up with our partners in the air. General, we do have a graphic of highway 41 which youve just 47 which youve just talked about. It goes from raqqa to mosul. It also leads all the way down to baghdad. Its interesting that its in bright red because it is a main artery. You see all of the different vital cities. Thats what theyre fighting for. You have highway 47 going across the north, alisyn. Thats in and out of kurdishheld territory as part of the Kurdish Regional government. The road going north and south out of baghdad, everyone will recognize the names of the town. Thats highway 1 going from baghdad to mosul. It will go through the towns of bayji, hewiji. That highway leads to kirkuk. Were talking Iraqi Security forces. The Iraqi Security forces have been fighting in towns like bayji and ramadi, in hawija, in kirkuk. They are trying to reach mosul, the second largest city. You have the Kurdish Peshmerga fighters fighting along highway 47. If you can cut those two supply lines and eliminate the ability of isis to move back and forth across the area, youre executing a very well thought out campaign plan. What weve seen in the past, as the Iraqi Security forces have grown, theyve been able to hit one place at a time. Whats been significant over the last couple of days is weve seen a whole lot more action in different areas. General mark hertling, thanks so much for explaining this whole region to us. We really appreciate all of your expertise. Thanks so much. Chris . Thank you, alisyn. Lets turn to the battleground of politics and donald trump is making headlines for going off in iowa, a 95minute tie ride that even by trump standards left the audiences and analysts stunned. Cnns athena jones is live in des moines. Good morning. Good morning, chris. It was a sight to, hold last night. One of the longest and most eyerising tirades from trump yet, full of insults against his gop rivals, Democratic Leaders and the media and more tough talk for isis. I would bomb the [ bleep ] out of them. Cursing and mocking chief rival dr. Ben carson. How stupid are the people of iowa . Reporter unleashing his most aggressive attacks yet in what amounted to an hour and a half long ran in the iowa. How stupid are the people of the country to believe this crap . Reporter the billionaire gunning for carson. The two are virtually neck and neck in recent polls here. After the retired neurosurgeon wrote in his autobiography that as a teen he tried to stab a friend only to have it stopped by a belt buckle. I have a belt. The belt moves this way. It moves this way. It moves that way. Anybody have a knife want to try it on me . Believe me, it aint going to work. Reporter trump comparing carsons selfdescribed pathological temper to an incurable disease. I dont want a person thats got pathological disease. If youre a child molester, a sick puppy, youre a child molester, theres no cure for that. Reporter a theme of attack he used earlier in the night on cnn prompting Carly Fiorina to jump to carsons defense, writing in a Facebook Post all the money in the world wont make you as smart as ben carson. During his tirade, trump also attacking Hillary Clinton. Shes playing the woman card up. Thats all she has. Honestly outside of the womans card she has nothing going, believe me. Reporter the one time clear frontrunner also claiming to know more about the terrorist group isis than u. S. Military generals. Saying he would bomb areas controlled by isis that are rich in oil. I would just bomb those suckers and thats right, id blow up the pipes. Blow up the refineries. Every single inch. There would be nothing left and id take the oil. Reporter it was really something to watch. Now, in response to trump attacks, a top carson aide says that trump resents carsons rise and is lashing out. It will also be interesting to see how republican primary voters respond. So far they havent punished trump for any of his wild statements. The question is, is that going to change . Chris . I dont know that hes called them stupid before either. Well see how that plays. Well get response from the carson camp and well hear more from mr. Trump himself while being tested on cnn last night. Well get plenty of reaction to what this will mean, his new phase of attacktics as well. Armstrong williams will be here to talk about what he thinks is going on with trump and why he does not think it will work. Attacktics. I like that. Thank you.

Tim lynne was the pilot. This is insanity. Why does anybody think this is funny or a good idea . Luckily now, theyre catching the people. Lets hope they put this to rest. My goodness. Donald trump held a remarkable event, complete with a reenactment and props. Wait until you hear what he says about critics of his immigration plan. Trump unfiltered ahead on new day. [ male announcer ] whether it takes 200,000 parts, 800,000 hours of supercomputing time, 3 million lines of code, 40,000 sets of eyes, or a million sleepless nights. Whether its building the worlds most advanced satellite, the space station, or the next leap in unmanned systems. At boeing, one thing never changes. Our passion to make it real. Im mary ellen, our passion to make it real. And i quit smoking with chantix. I have smoked for thirty years and by taking chantix, i was able to quit in three months. And that was amazing. Along with support, Chantix Varenicline is proven to help people quit smoking. It absolutely reduced my urge to smoke. Some people had changes in behavior, thinking or mood, hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. Some had seizures while taking chantix. If you have any of these, stop chantix and call your doctor right away. Tell your doctor about any history of Mental Health problems, which could get worse or of seizures. Dont take chantix if youve had a serious allergic or skin reaction to it. If you have these, stop chantix and call your doctor right away as some can be lifethreatening. Tell your doctor if you have heart or blood vessel problems, or develop new or worse symptoms. Get medical help right away if you have symptoms of a heart attack or stroke. Decrease alcohol use while taking chantix. Use caution when driving or operating machinery. Most common side effect is nausea. I cant believe i did it. I quit smoking. Ask your doctor if chantix is right for you. All right. So before he lit into ben carson at a Campaign Stop in iowa, donald trump was blasting critics of his immigration plan as well. Cnns erin burnett sat down with trump and got a taste. So i want to ask you about the immigration discussion thats going out there. You put it front and center. You wouldnt have been talking about immigration had i not put it on the table. You were criticized heavily theyre weak people. I watched jeb today. Theyre weak people. And kasich made a fool out of himself in the debate. What he said was ridiculous. Everybody was uniform in the fact that cakasich did a bad jo on the one point of importing 11 Million People, even marco rubio said marco rubio is in favor of amnesty. He was a member of the gang of eight. He was always in favor of amnesty, people pouring into the country. Then what happened is when people found that out, he sank like a rock in the water. He says hes for anyone with a criminal record. People like that now hes saying something different. Which is something you would support. Hes much different than he was in the past. The question im asking is how do you take 11 Million People and make them leave. In a process, a humane manner. Theyre not going to want to leave. Theyre here illegally. If a person comes across the border and you send them right back, Border Patrol sends them right back, theres not a big court situation. What about the guy already living in detroit. Whats the different between somebody who comes over the border for two i das, he gets caught and you bring him back. Whats the difference between that and the person here for a year. In terms of finding them and getting them to go. That costs money and you have to have the people. You cant also do everify. Where the employers arent going to be hiring them and then everyones going to go back. Thats one way of doing it so you dont have the problem. You do everify where an employer has a big problem if he hires these people. Theyll all go back of their own volition. Im sure youll say they can do it cheaper. They say 600 billion, bigger than the department of defense contract. Excuse me, excuse me, they also say its 15 billion to build a wall that ill do for 6. Say you do it for 100 billion. Its bigger, better, stronger and more powerful. Illegal immigration each year costs us between 200 and 300 billion. I dont know if anybody gives you those numbers. Probably not. When you include crime and other problems its more than that. Youre talking about between 200 and 300. They pay in taxes. 24 billion in taxes. You really believe they pay taxes . They pay local, state. Dont be naive. Do you think that an illegal migrant getting money is going to be paying taxes . Sure, some probably do because the employers are insisting on it. Theres very little percentagewise, theres very little, probably 5 , s10 . Theyre here illegally. Theyre not paying taxes. I hear them all. What i do, i make things really good. I fix things. And you know, im a real fixer of things, not jeb bush. Okay . Im a real fixer. I can really do things. One of the reasons the wall never got built, they couldnt get the Environmental Impact statement if you can believe it because something was in the way. They couldnt get their Environmental Impact statement. Heres the thing. Between everify which will take care of a big portion of them, you have to go back. If they cant get a job, theyre going back anyway. We dont have to knock on doors. On this point about humanity, are you going to be sending in officers, a force of people into peoples homes to get them out . Well be giving notice. Well be saying you have to go back to wherever the country is. Its going to be countries, all different countries. Not one country. Back to the country. Well do it in a humane way but between everify and other modern systems, a lot of that will happen automatically. And dont forget, were taking tremendous numbers of jobs from people that were born in this country. You understand that because when you look at the roads, you have 100 Million People that potentially want to work and they cant find jobs. They dont want to pick grapes, though. Maybe not. We can solve that with work visas where they come in and work legally, they pay taxes and then they go out. Im all for that. I think thats true. Because i agree with you. They might not want to pick grapes, not their thing. They dont want to do that. Thats okay. But well have a work visa where they can come in, work, and then at the right time they have to go back out. President obama for his part not buying Donald Trumps immigration plan. In fact hes slamming the republican candidates proposal going as far as calling it unamerican. First of all, i have no idea where mr. Trump thinks the money is going to come from. It would cost us hundreds of billions of dollars to execute that. Imagine the images on the screen flashed around the world as we were dragging parents away from their children and putting them in Detention Centers and then systematically sending them out. Nobody thinks that that is realistic but more importantly, thats not who we are as americ
