Doesnt mean you got to spend a lot because dennys brought back the super slam™. With eggs, hash browns, bacon, sausage and buttermilk or pumpkin pancakes. All for just 6. 99. The 6. 99 super slam™ is back see you at dennys nightline, the hunt for isis fighters, continues. Here now, david muir. Good evening and thanks for joining us. Tonight, the abc news exclusive right here on nightline. The hunt for isis fighters. Were about to take you deep inside iraq. After President Trump celebrated the defeat of isis, their territory taken back, where those isis fighters are now. Tonight were with u. S. Forces, as they hunt down those fighters. And our exclusive access inside syria, the refugee camp where the children are dancing around the isis flag. And the prison where isis fighters tell us they are determined to fight again. After dark in baghdad we board a blackhawk. U. S. Forces giving us exclu access to an assault under way right now. As the u. S. And iraqis hunt down isis fighters. We are flying out over baghdad right now after nightfall. All part of an operation to capture isis fighters. Intelligence shared between the americans here on the ground and the iraqi fighters. Were going to be landing between fallujah and ramadi. This operation now under way. They take us west of baghdad to a base where they hunt them down from above first. 24 hours a day surveillance in the sky. Looking for isis fighters now hiding in the desert. The mountains, the caves of iraq. And in the villages isis fighters trying to blend into the population. You find yourself back in Anbar Province to catch isis fighters. Yeah. We sure do. Did you ever think that would happen . I did not. Its a very surreal experience to be back here in anbar 14 years later from doing offensive operations out here. Remarkably almost the same fight plan. It really is. Very familiar flight plan. Thats right. We drive to the command center, where we learn there has just been a strike on isis fighters. Has it been lucrative . Its been successful. Reporter u. S. Strikes from the air and then the iraqi forces sent in on the ground. Ns center. They take us past the concrete barriers, where we find u. S. Troops and their eyes trained on isis. So welcome to anbar and task force spartan. This is our combat operations reporter where they reveal to us the isis fighters they have just targeted. You were telling me youve already seen enemy movement. We have. Reporter and tonight abc news obtaining these images of that strike. They tell us two isis fighters were spotted where they were sleeping, not far from where they were keeping their weapons. This is where they retreated to. We found them because they got up and moved. They went over to another location to pull some weapons out. When they went back into their beddown location and we were able to go ahead and conduct a strike on them. Because they dont have a territory anymore, theyre literally trying to blend in with other iraqis . In the desert sometimes they try to blend in, look like shepherds or just transiting through the area. In the cities they try to look like the citizens and the people of anbar so that they dont draw attention to themselves. Reporter this strike just days before on an isis tunnel in mosul. That city controlled by isis not so long ago. And this strike at another isis they were sleeping at night. Best way to describe them would be sleeper cells because theyre there intentionally not to draw attention, live another day to fight. But youre fairly convinced youve got two isis fighters. If i was a betting man id put money on it. Reporter at sunrise we are take tyne remote area not far from the command center where were told helicopters will soon drop off iraqi commandos being trained by u. S. Forces. They land, american troops vanishing in the desert sand. These u. S. Forces are shadowlike, watching the iraqis as they drill. They storm this small space, not unlike the caves with corners theyll soon be sent into to flush out isis. The iraqi commandos will be the front line against isis here. The fact that theyre able to do this on their own speaks a lot to their capabilities. Those american drones, though, hovering up above, finding intelligence and when you share it with these iraqi commandos on the front lines. It was pretty good that we were hearing that above because thats exactly right. Reporter in the middle of the desert we are shown the unmanned drones. They are guarded, fueled, and ready for flight. In the skies over iraq eight hours at a time. This is where theyre actually operating the drones that are doing surveillance right now over the iraqi desert. The mountains and the caves where they believe these isis fighters are still hiding. You can see this private first class is looking at some terrain right now. Reporter we are allowed inside. A rare view of what it is they see. The kind of terrain theyre scouring. And were about to see for ourselves whats playing out right now deep in the anbar desert, where isis fighters cross over the Syrian Border into iraq. As you can see, we are back up in the air again flying over the iraqi desert. We are headed west of ramadi. In the anbar desert to find a command center for this operation under way right now. To capture isis fighters. Our flight over the desert in 115 degree heat. We hear the pilots pointing out every lone vehicle, every lone person they see on the horizon. They are ready. And then we see it. The small command post just 50 miles from theyr just before us. We are were at the western edge. Hopefully air field were deep into the command area of operations. Reporter this remote post in the outer reaches of the desert. I took note while we were flying out here you could hear the pilots talking about vehicles off in the distance, completely aware of every isolated scene on the way out. Just a reminder that isis is out there. Reporter as we arrive we learn an isis fighter has blown himself up, killing another isis fighter in the process. The iraqis then moving in capturing five more isis fighters at that location. We have blurred the iraqi translator for his safety. This is where the operation is under way right now deep in the anbar desert about 50 to 60 miles from the syrian b iraqi troops m and the tribal a setting up this defensive perimeter. They are here to find these isis fighters. Theyve captured another seven of them, krarmted and killed here in the search for these fighters. The new reality, this is where the isis fighters are hiding. The iraqi general is waiting for us. Hello, lieutenant. Good to see you. Good to see you. They take us into this small tent where the general using his laser pointer shows us where theyre hunting. Are you confident youll be able to get rid of isis in iraq . Yes. Reporter and then the general offers this. They know the iraqi forces are looking for them. They are looking for them deep here in the iraqi desert. But right across the border in syria abc news is shown the other major threat. Senior u. S. Military leaders telling me this refugee camp is one of their greatest concerns. Inside elhol, tents as far as the eye can see. Children sitting in the open air. Mattresses on the back of pickups. The young refugees looking out. But what you dont see, u. S. Militaries leaders say, are the isis fighters who have disappeared into the crowd and in parts of the camp children now celebrate the isis flag. Reports of isis flags inside that camp . Thats right. Theres one section of the camp where most of the hardcore ideologues seem to be located. Raised an isis flag. Children were dancing around the flagpole. Clearly indoctrinated into that ideology. Its a legitimate concern that this is becoming a breeding ground. Absolutely. Reporter at another refugee camp arisha we find so many Smiling Faces but among them the children we are told who are being radicalized. One of the camp managers says he fears what the future will bring because he says isis is inside now, stealing childhoods. They prevent them to go to school. There are some children who promise that out of the camp they will go maybe with isis. Reporter u. S. Military leaders say it is impossible to know how many mothers have also been teaching their children how to hate. We see indoctrination of their children as well. So you can almost see the next generation of isis being brought up in that ideology. Right there in the camp . Right there in the camp. Absolutely. Reporter and our team is taken to one last place. One of the prisons just across the border in syria. Where the americanbacked forces are holding those prisoners. There are at least 10,000 of them. 2,000 have come from all over the world, including the u. S. , and inside the prison abc news was given rare access. Down the hallway the prison doors bolted. Inside the vast majority are isis fighters. Some proud to look straight into the lens. This fighter, abdullah halem, says he was a Security Officer for isis for a year. He worked with explosives and targeted police stations. And he tells us he will rejoin isis in released. So he can fight and kill americans, he says, because they are killing us and we will kill them. Is there any question in your mind that they would take back territory if given the opportunity . Not at all. We know thats their plan. Right now. Absolutely. Reporter and tonight this question. Who will ultimately take these prisoners . There are reports up to 10,000 isis fighters are being held by americanbacked forces right now. What do you do with those fighters . Its a really good question. And its a tough question. Weve got to get the countries to take ownership of their folks who came here into the battlefield, take them back and figure out how to bring them to justice. Reporter and part of that means americans who took up the fight with isis back home to face justice here. There were americans among the fighters. Thats right. And at least some of them have been sent home. Correct. Reporter tonight several americans home already and charged. When we come back, the children r5dicalized. Brought up by parents, family members devoted to isis. You saw the isis flag, reports of the children dancing. In a moment, what theyre doing right now for the children left behind by fighters who did not come home. Some of their parents surrendering. The isis children orphaned. Whats being done to rehabilitate them, to free them of their isis ideology, and what the children reveal, what it was like. Life on the inside, when we come back.

Nightline, the hunt for isis fighters, continues. Here again, david muir. Reporter these are the children of isis. Some are young. Some are teenagers. All of them left alone in some way by this war. Some of their parents killed. Others surrendered. But what they have in common is a childhood in which they were raised to believe in isis. Some of them taking up arms themselves. Child fighters for isis. Abc news was given rare access at the hora youth detention and Rehabilitation Centers in northeast syria where in this classroom every seat is filled. They learn here, they sleep here in bunkbeds where they do their homework. In the courtyard they play sports. Theyre trying to build a new and Safe Community for these children. Each of these children has been given a task. Some here in the kitchen. The workers here hope that this new life, this new normalcy will help pull the children away from the isis ideology. Brushing their hair, cleaning up before their meal. But many of the children still bear the scars of war. Amjan told the staff at the Detention Center his arms and his face were burned in air strikes more than a year ago. He says he worked under isis, he did policing, he was a guard, and he is honest about who he wants to see again. He says, i want to come back to my life and stay with my family. And thats part of the fear, say workers here, is that these children will one day return to their families and perhaps to the only belief system they ever knew. And for some of them that could mean a return to the battlefield. This young man, sulai, is 16. He says he was forced into i. C. E. Because his mother married an isis fighter. They told my mom and i if we try to leave theyll kill us. They took our fingerprints, pictures. They told us this is the last time, you try to leave another time well kill you. Reporter he says he and his mother escaped and surrendered and he hopes freedom will come soon. From the Detention Center and from isis. Im here because my mom, she made a mistake, really big mistake in getting married to that guy. And i hope one day we get to go back home and forget about all of this that happened. Reporter and sulai who ended up with isis when he was just 12 says that ideology hes trying to escape is still alive and well here in some corners of the rehabilitation center, that some of the young men here still believe in isis. They still believe in everything they were taught and theyre convincing me, trying to tell me you have to be like this. For now i play the roling in something happens. Reporter there has been so much suffering here. The boy who says he fought for isis in iraq but they turned on him. He says they accused him of stealing and the punishment, he says, they cut off his hand. But still, he is grateful to be here. When i came here, i didnt know how to read or write, he told us. So now i know how to read and i know whats wrong and right. But for sulai told us for every child happy to be here there are those who say they cant wait to go back. They still believe theres a chance for isis to come back. That when they go out maybe theyre going to go join back with isis. Isis is a danger. Reporter one of the Staff Members who works here says isis is still a dangerous virus. She says its a tipping time bomb here and elsewhere. There are time bombs in the prisons, in the camps. Reporter they are trying to rehabilitate the young minds here one at a time. But in the refugee camps now overfleeing like alhol it is impossible to track. Senior u. S. Military leaders tell us 60 of the people are under 18 and they know some of them could be swept up in the next wave of terror. And on the other side of the border in iraq we fly back to baghdad. And we witness what the u. S. Military already knows, that this is a fight far from over and many of these military leaders have been to iraq before. Came back again for the isis fight. Reporter Brigadier GeneralWilliam Seale walks me through the hallways of what used to be the Baath Party Headquarters in baghdad, when Saddam Hussein ruled here. This is where Saddam Hussein had his parades. Thats correct. Right here. Reporter where u. S. Allied forces delivered punishing strikes. T the debris sitting where it was 16 years ago. All these quarter later. Reporter we see where offices and desks once sat. Its like a time capsule. Reporter now 16 years and several tours later seale is back in iraq. This time the mission is very different. Hunting isis fighters who might have lost their territory but who are still fighting tonight. Im security. Six tours later, did you think we would be heading out to anbar to get the enemy again . It is surreal that were going back out to al anbar. Thats where they are.
