[Blitzer:] We're about to show you some disturbing images, tormenting of prisoners, mass executions all captured on video. ISIS terrorists are sowing deep fear right now, stirring up sectarian hatred with these cold-blooded killings. Let's get a closer look. Our senior international correspondent Arwa Damon, she's in northern Iraq, in the city of Erbil. She's joining us live right now. These are horrific video pictures we're seeing. What's the latest?
[Arwa Damon, Cnn Senior International Correspondent:] That's right, Wolf. We do have to warn our viewers that they are going to be very difficult to watch. But this is just one example of ISIS's brutality.
[Damon:] Two of the captives have Iraqi border guard patches on their sleeves. The bearded man demands his prisoners repeat "Islamic state here to stay." The first two comply, fear on their faces. The third struggles to formulate the words. Moments later, this. He appears to be dehydrated, barely reacting to what's happening. In the next video, he is dead, his jaw blown off. At the end of the clip, the ISIS gunman proudly declares, "We killed a Shia." This Facebook page's profile picture matches the man in the video. He goes by the name Abu Hamza al-Mohammed from Tunisia. We accessed the Facebook account before it was taken down, posted on it these stills of the same execution. There's another photograph that shows the other four men dead. They're accused of being Maliki's dogs, a reference to Iraq's Shia prime minister. Abu Hamza boasts about how he blew the infidel's heads to hell. Location, Iraq. In another post, Amu Hamza says, "Send these videos to the Shia," an effort to foment sectarian rage in what has become a ruthless battlefield. Many of the images posted online are too horrific to show. Stills posted on an ISIS Twitter account show a shallow ditch filled with bodies, all accused of being members of the Iraqi security forces. Often we don't know who the victims are. But in this case, we managed to identify the man who could not speak. He name is Jafa Zinseki, 36 years old. A father of two boys and a girl, who adored his children and took the job as a border guard to build them a home. Wolf, what makes this all the more unbearable and difficult for the families that they're unable to retrieve his body, because ISIS controls the area where it is believed to be at this point, Wolf.
[Blitzer:] What a horrific, horrific situation. Arwa Damon in Erbil. Arwa, thanks very much. Full analysis of what we just saw coming up, but there's some breaking news I want to get to right now. A tornado is on the ground in Nebraska. Our meteorologist and severe weather expert Chad Myers is standing by. We've got live pictures. Look at those funnel clouds, Chad. What is going on?
[Chad Myers, Cnn Meteorologist:] Unbelievable tornado on the ground just through the Pilger, Nebraska, P-I-L-G-E-R, Pilger. We looked at it earlier as it grew very, very close to Stanton, Nebraska. This is what we call a stove pipe, straight up and down tornado. You're noticing another one in the background. Two tornadoes on the ground. These are live pictures. This is U.S. 275 in northeastern Nebraska. To the east of Norfork, Nebraska, about to cross that road. That car just drove right down that road right toward that tornado. And so did that one. And you can see it right in front of you. You have to know what that is. So this is the problem when you're storm chasing or if you don't know what you're talking about, don't know what you're doing, they're looking at this tornado right now and these cars are passing him. You need to be stopped. You need to be away from this tornado. A dangerous situation in Pilger, Nebraska.
[Blitzer:] Near Stanton, we're told. It looks like there's two funnel clouds on the ground over there. There's one right in the middle of the screen to the right. There seems to be another one. Is that normal?
[Myers:] That is absolutely not normal. There was a tornado on the ground. You talked about it near Stanton. That tornado went away. These chasers were to the east of that tornado, thinking they were in very good shape. Then all of a sudden, we saw the new tornado signature on the radar. The storm regenerated a tornado about four miles east of that first one. Separated from the first one and moved there. This one you're looking at right now is a very large maxi tornado. We're looking at EF-3, EF-4 damage that moved through that town. We saw debris in the sky from that town. It is now north of U.S. 275. And the one that you're looking at, you just can't see it to the right if they pan to the right a little bit, that one would be moving toward Wisner, Nebraska. Wisner, Nebraska, right along Highway 275. You need to be taking cover now. This is open country, but these are major tornadoes on the ground. Wind speeds in excess right now, Wolf. I'm going to go 175 to 200 miles per hour. Paralleling themselves.
[Blitzer:] Hold on.
[Myers:] And in northeastern Nebraska.
[Blitzer:] Ben McMillan is on the phone. He's driving this vehicle that we're seeing right now. Ben, tell us what's going on from your vantage point.
[Ben Mcmillan, Storm Chaser:] Hi, Wolf. We're just northwest of Wisner, Nebraska, on State Road 275. We're behind these tornadoes. We're in a safe position. They're moving away from us. But this is a very deadly situation if you're near these. We've seen 10 to 20 buildings get completely destroyed at this point. We also have two tornadoes on the ground. Wolf, I don't know if you can see both of these tornadoes on the east side of the screen.
[Blitzer:] We see we see these two tornadoes pretty close to each other. How close are they? They're on each side of the screen right now. We're showing our viewers your live pictures.
[Mcmillan:] They're probably about two to three miles apart. And again, they're kind of rotating around each other. Again, we are west of the storm. So please, if you think this is a safe job, it's really not. You've got to be, you know, at a safe place out ahead these things. We're behind them. So we're all right. But take this very seriously. These are the kind of storms you need to be underground to survive like hit Oklahoma last May.
[Blitzer:] It looks like people are driving toward those two tornadoes right now. But you're saying they're moving much more quickly in the other direction?
[Mcmillan:] Yes, I'm very worried. People aren't aware of what these are. Not a lot of folks have as much experience as our team does recognizing and interpreting severe weather threats. And I just don't know if these folks are trying to get out of the way or rush home and check on loved ones or what they're leaving at this point.
[Blitzer:] How close are you from because we're looking at live pictures. How close are you to these tornadoes?
[Mcmillan:] We're probably about two to three miles at this point. We're now south of the main one in the middle of the screen on state road 275. Northwest of Wisner, very small town here. But folks south of Lane, Nebraska, and west of the town of the other one starts with a "P," west of Pender, Nebraska. That's the main area of threat at this point. These are violent tornadoes continuing to turn east across the countryside.
[Blitzer:] Hey, Ben, I want Chad Myers to talk to you for a moment. Go ahead.
[Myers:] Ben, I just you to remember now, you see all those power lines to the left. There will be a point on 275 that you're going to run into those power lines over the roadway. Keep that in mind. A lot of those power lines could still be alive as you drive over them. I know that's your job.
[Mcmillan:] Thank you very much.
[Myers:] But that both of those tornadoes went right over that highway. I know you saw them.
[Mcmillan:] Yes.
[Myers:] Wolf.
[Blitzer:] I was I wanted to ask you, Chad, and maybe Ben can weigh in. The there's an official the official situation is being described as a particularly dangerous situation alert. Particularly dangerous situation alert. Chad, what does that mean?
[Myers:] There will be on the ground large max I tornadoes like the one you're seeing right there on Ben's screen. That is a big tornado, wide on the ground. Ben, what do you think? A half mile, mile wide at the base?
[Mcmillan:] Yes, we had about a half mile wide tornado. Then we had these horizontal vertices which you only see in the most violent of tornadoes. I don't know if you remember this video coming in from Tuscaloosa. It had a lot of these horizontal vertices, which indicates how strong these really are. We're seeing lots of tree and structural damage. And again, very concerned about the residents in eastern Nebraska at this time.
[Myers:] Have you come upon any damage yet? You're getting very close to where that tornado went over.
[Mcmillan:] We haven't seen any large cities or residential structures. Actually, we're just seeing the first out here off to the right. Can you see below the tornado, Wolf? Those structures in the shot?
[Blitzer:] Yes. We see them.
[Mcmillan:] Yes, that's the damage that literally just occurred seconds ago here. The grain bins had their roofs ripped off. Those are normally round as you can see in the left side of the shot. The tops completely removed, and I'm getting worried folks watching about injuries and possible fatalities now. This is not a light situation. You need to take it very seriously. And we're very, very worried for folks at this point.
[Blitzer:] This is pretty rural, this area. It's not very urban, right?
[Mcmillan:] It is it's pretty rural. There's still a lot of farmsteads here in eastern Nebraska. It's a large industry. There are still lots of folks with their livelihood out here. We don't want to underplay the threat.
[Blitzer:] Chad, that tornado looks huge. I'm not an expert by any means. But it looks so devastating. Give us an explanation of how big this is.
[Myers:] You know, Ben just said, it's probably a good three- quarters of a mile wide on the ground. I'm looking at it now. And Ben, you're on a highway that's going north and south. There's a little spin right to the north of you a half a mile. I want you to keep looking forward as you're driving. I know you are, but that second tornado that did spin back up into the clouds could come back down at any time. Wolf, the storm that you're seeing on the screen is now becoming the main tornado. It is still many miles from Penger. It is still many miles from Thurston. A lot of wide open countryside here. But this is going to be the big dawn tonight, EF-4, possible EF-5 damage. We have debris signatures in the air, which means the radar itself is picking up debris in the air. Go ahead, Ben.
[Mcmillan:] And left side we have a large tornado, a huge tornado that has formed left side of the screen. Again multiple tornadoes on the ground here.
[Blitzer:] How many are you talking about, Ben?
[Mcmillan:] Two possibly three. I've never seen anything like this Wolf. I've been storm chasing for probably 10 to 12 years professionally. This is just very, very dangerous.
[Blitzer:] What's your contingency plan, Ben, if these tornadoes move towards you?
[Mcmillan:] Again, we're south of the circulation. So we're, you know, in a safe position. But I just I guess I could turn around if I had to. Again, we're just trying to get this information to you so you can get it out to the folks in this area and protect their lives and property.
[Blitzer:] If anybody's watching in this area, Chad, what do they need to do right now? Remind them.
[Myers:] Absolutely get underground if you can. This is a tornado with winds of 200 to 225 miles per hour right now. And you need to be underground or inside your home with as many walls between you and the outside as possible. And what I don't want you to do, Ben, is get on any dirt roads now. This storm had a lot of rainfall before it started, before the tornadoes came down. All of those dirt roads in the Nebraska, even some of the they call them all-weather roads are wet and swampy and you cannot drive on them. You don't want to get stuck on a dirt road. Look at that, Wolf. Two tornadoes on the ground right now. Spinning there in northeastern Nebraska just north now of what would be Wisner, Nebraska, west of Pender, Nebraska. Still a lot more land here. Wide open country. But that doesn't make it any less dangerous if you're in the way.
[Blitzer:] So what happens, Ben, your experience, how long do these tornadoes stay where they are and move on? I think we just lost Ben.
[Unidentified Male:] Get inside, please. Get inside, please.
[Blitzer:] Yes. Looks like we lost Ben. It looks like there's SOME cars stopped over there, Chad. People are getting out of those vehicles. I don't know how smart that is.
[Myers:] Well, you know what, a pickup truck and a NOAA weather radio doesn't make you a storm chaser. Ben knows what he's doing. He knew where those tornadoes were. He has a radar in his car. He could see it, and he could see where the great rotation was. s I was watching Ben chase the first tornado going east on that 275 highway, the second tornado and then the third developed to his right. And I was very concerned that he didn't notice it. But then his spotters in the car told him, "We have to stop. We can't go any farther. There's another tornado on the way right in our path." And he did stop. This is unbelievable video, Wolf. I have never seen two these are now EF-3, EF-4 tornadoes...
[Blitzer:] All right...
[Myers:] on the ground at the same time.
[Blitzer:] Chad, stand by. We're going to reconnect with Ben. We'll take a quick break. You're right, unbelievable images of these tornadoes. Our coverage will continue in a moment.
