Terror attack on israel was at the Supernova Festival, a dance party just 3. 3 miles away from the border with gaza. More than 3,000, mostly young people, had gathered in an open field. It became a killing field. The site of the single biggest loss of civilian life in israels history. Over the course of about six hours terrorists killed more than 260 people there. Many were slaughtered at the site. Others were ambushed or hunted down as they tried to flee. We still dont know how many party goers were kidnapped and how many of those people may still be alive. Being held somewhere in gaza. Hamas has posted Hostage Videos online and desperate Family Members in israel have resorted to scrolling through jihadist videos searching for videos of their loved ones. Only now the story of what happened at the supernova Music Festival coming into focus. Using video from multiple sources and eyewitness accounts from survivors weve been able to document how coordinated this attack was and just how brutal. Some of what youll see tonight is tough to watch but it is for now the most complete look at what took place we reported so far. It was 6 00 a. M. On saturday morning, october 7th. The sun was rising over southern israel. I was standing with a friend. We looked together at the sunrise and i told her, look how beautiful she is. What a magical sunrise. What a magical day. Thousands of young people had been partying through the night at the Supernova Festival, a trans music rave. I made a video on social minutes before the attack and the crowd goes crazy. Ive been in a lot of festivals. One of the best ones. So before the attack. After analyzing dozens of videos and interviewing survivors cnn has been able to piece together how the hamas Terror Attack unfolded. 70 miles south of tel aviv, about 3. 3 miles from israels border with gaza. Festival organizers had been setting it up for days. Some party goers didnt learn the location until shortly before the rave began. Usually to dance festivals you dont give the location until the last day. Because originally the festivals were illegal in most of the country so we never give the location until a couple hours before. This is a tradition in this trans culture. Reporter there were police and Event Security on site but party goers had been asked to leave any guns at home. They asked all the people that attended the event to be calm and peaceful. Dont bring any weapons. Usually you really dont think that you need to bring weapons to a party. It is supposed to be the most safe place that we all know. 3yearold hikoen was going to skip the party but changed his mind after a friend convinced him not to i told her, listen. I am really, really tired. Try to maybe sell the tickets or take other friends with you. She sent a message to the organization and the organization told her it is too close to the event. It is not possible to change the ticket anymore. Then she wrote to me, its destiny. You dont have a reason to be afraid. I would like you to come with me. Then i wrote to her, okay. Im in. The 31yearold traveled to the party with two friends and met up with his other friends. I told him about this party. I pushed him a bit to come with me because we enjoyed some festivals like this before. Also enjoying the festival, a 22yearold restaurant manager. His vision is to be a professional, the owner eventually. A 22yearold german Israeli Citizen had come as well. My daughter is very artistic. She likes drawing. She is a true artist. She likes Music Festivals. She likes to dance. Another party goer was a husband and father of a 3yearold boy. A huge heart. He has an ice cream shop. A very smart guy. He loved life. He went to celebrate life. The celebration was supposed to go on all day, but at 6 30 a. M. The music stopped. The music shut down. It sometimes happens. In the first seconds i was, like, yeah. Sure. The music shut down. You could see these little blocks of light in the distance awe think, okay. This is maybe fireworks. This video was taken at exactly 6 30. Like 20 seconds after that we realized those lights were not fireworks. This is missiles. This is rockets. I remember police guy take the microphone. And say in hebrew which means, red siren. Red siren. Please go to the shelter. What . You know, like we are in open field. What shelter . When you are in open area like that, the best thing that you can do is to lie on the ground and put your hand on your head. Party goers could hear the rocket warnings. Everything okay . But many were not concerned. Its far away. Its far away a man in the parking area says. Dont worry. For a lot of israelis, alarm is not something that you get so excited and scared about. I didnt get nervous because i used to it because in israel every few months, from gaza, you know, we are surrounded by enemies, so i used to see so many rockets over my head. So i was chill. Rockets arent unusual in southern israel, but armed paragliders are. You could see them coming from above between the rockets. I didnt think it was any kind of danger. We saw the paragliders from afar but we didnt think, we never occurred that they carry terrorists inside of them. You can hear a woman asking, whats happening . It was around 7 00 a. M. Some party goers were already trying to get out. I understand something really getting wrong when i start hearing the live shooting. I could recognize it as a type of shooting, Terrorist Idea of power. Three type of shooting. One is single, pow, pow, pow. One is going like pow, pow, pow. And then like open fire tatatata. I could understand this is not idf. This is terrorists attacking us and shooting us. It was far away but you could hear that and then i understand, yeah. We need to get away from here. A 25yearold photographer got to his car and out of the parking area. There was like a small jam of cars but the policeman between the field and the main road stopped us. He says they told him there was shooting On The Road North and he should head south. I was probably one of the last ones who escaped that without getting the live shooting on me. Just decided that i want to drive away from here. Maya was working the festival and got to the parking lot around the same time. I got into my car, which because i was like really close to the exit so i didnt get stuck that much in the traffic of people going out so i was able to get out of the party space and into the road and i thought, i thought i was safe. Unlike inor, maya drove north toward tel aviv but hamas gunmen were already on that road ahead of her. They arrived on motorcycles and in trucks, armed with Automatic Weapons and Grenade Launchers and quickly closed in from three directions. As this drone video shows, the traffic jam of cars trying to leave would prove deadly. The cars were stuck. And then a few moments later an officer coming toward our way, terrified, terrified for his life. He is screaming, like there is terrorists. Theyre shooting people. You need to leave your cars. Leave everything here. And run. Run. Run for your life. Hamas came from the west. They also were coming from the north and from the south. So heading east through this open field was the only way for many people to try to get out. The problem was its an open field and they were easy targets. Its not yet known how many people were shot running away or in hiding places nearby. But it was early and the Slaut Hearslauter had just begun. Hamas gunmen had breached the Fence Separating Israel and gaza in multiple locations according to the idf. By 7 00 a. M. They were along this entire stretch of highway. Police and festival security exchanged fire with the heavily armed attackers but they were out gunned and out manned. As chaos spread, a traffic jam in the parking area made it difficult for anyone to drive on to the main road and get out. You cannot go from everywhere. Only one line to the roads. You really get a sense of just the chaos that took place here as party goers started to realize what was happening. Many rushed to the parking lot trying to get into their vehicles but they never made it out. Those who were able to drive north or south quickly realized hamas gunmen were waiting for them. We got on the road. Then we ran into an ambush. They shot about 8 to 10 gunshots on the car. A lot of the cars started to turn around and honk and be like turn around. Turn around i remember holding the wheel. Okay . And im telling myself, get ready, buddy. They are coming. At 7 39 a. M. This Dash Cam Video shows a hamas Gunman Firing into a car on the road just north of the festival site. The car accelerates. And more gunmen shoot at those inside. This gunman also shoots repeatedly and at least three shots hit the dash board. The car accelerates faster and this gunman fires as well. The car crashes into another vehicle parked on the side of the road. It is not known how many people were inside. There were at least eight Bomb SheltersOn The Road North and south near the festival site. This is a part of israel that is under constant Rocket Barrage and has been so for decades. And so there are many sites throughout the region that have these fortified, concrete structures used for protection. Many of the participants found one of those structures and went inside assuming that they would be safe. Inor had driven south and pulled over to hide in a shelter. Three meters and three meters closed from every side, one door. We were all like 40 people. I could hear shooting that i recognized but it was like now very close. Like very close. Inor decided to make a run for it. He was lucky i took a decision that i think probably saved my life. At this shelter just north of the festival, you can see hamas gunmen throwing a grenade inside. A man runs out trying to escape. He was immediately gunned down. This 19yearold recorded this video inside another shelter afew miles north. The Concrete Room was packed with people. You can hear the panic in their voices asking whats going on . Are there Israeli Soldiers nearby . We got in the shelter with like 30 people and then after five minutes inside the shelter we just hear enormous, like, boom. Like explosion, grenades inside of our shelter. We arent going to show you the videos he recorded next. They are among the most gruesome weve ever seen. The deadliest kind of the grenades, those kind that throw pieces all over, metal pieces, screws, i dont know what they put in there. I saw my Friends Exploding in front of my face. Reporter he says he hid under body parts to survive. That is him, terrified, but alive. It was a horror movie. Reporter we found the shelter in the town. Someone had put a curtain up over the doorway but nothing could hide the smell as you enter. My cameraman who has experienced a lot of war began to retch and had to step outside. Theres bloody hand prints on the wall. Theres blood smeared on the walls. You can see probably these are either bullet holes or from the grenades that were thrown in here. Body parts have already been collected from here, but blood soaked clothes and shoes remain. This looks to be a bloody hand print. This shelter is no more than 15 feet long, maybe 5 1 2, 6 feet wide. The idea of so many people packed in here Standing Shoulder to shoulder terrified, screaming, it is incredible that anybody was able to survive. Cnn has identified at least four different shelters where Festival Goers were shot or killed with grenades. Back at the festival site, the butchering continued. Roughly two hours after it began, Dash Cam Video retrieved from abandoned cars in the parking area show heavily armed hamas gunmen moving around shooting freely. This Body Camera Video shows a Gunman Shooting repeatedly and systematically into portable toilets where people had hidden. This photo from another toilet nearby shows blood stains on the wall and on the ground. At 9 23 am nearly three hours into the attack this dash cam in the parking area records a bloodied Hostage Being Led away. Then under the car you can see another man hiding. He moves slightly then stops. A gunman runs right up to him and shoots him point blank in the head or upper body. When we return, the Festival Goers kidnapped by hamas. The objective was to not only kill a lot of jews but also to capture jews. There were those who were killed and those who have gone missing and are presumed being held hostage in gaza. We are talking about couples, talking about young people. We have families who are begging for information. Just some of the Festival Goers who were kidnapped. The situation is brutal. 22 years old, civilian, restaurant manager. He has nothing to do with the situation. Ricardos nephew was last seen in the back of this Pick Up Truck. His family wants the world to see this video. He had been stripped hifs clothes and was being hit repeatedly. If you dont know anything it is devastating. The parents are devastated. They cannot sleep. They cannot eat. His grandmother is a Holocaust Survivor. There is no harder thing a Holocaust Survivor can hear. She is 82 years old. She is not ready for this news. It is not known how many people were kidnapped from the festival but in total israeli authorities said as many as 150 men, women, and children may have been taken from multiple locations. Many families have had to Scour Jihadist videos online looking for any sign of their loved ones. We have heard from families of those that are believed to have been abducted essentially piecing together on their own what they believe happened using their last messages from their loved ones, using photos others took and other survivors potentially with them and trying to piece together exactly what happened in the final moments before they were taken by hamas. Hamas posted this video of this man tied up and terrified. This is the only image his brother found of him. All of his friends that go to this Music Festival i am trying and trying and keep trying until someone, one of them told me i just saw your brother on the video. This video coming from the other side from gaza side. Hamas posted this video of this woman forced on to a motorcycle screaming dont kill me and reaching out to her captured boyfriend. The couple had earlier sent out this photo while hiding near bushes at the festival. We suppose they probably were hiding for three, four hours. They started hiding after hearing the massacre and the shooting. You are a childhood friend. Talk about, what is she like . She is one of a kind person. She is very caring, down to earth. Very fun. Very ambitious. She takes her studies very seriously. Her mother is suffering from cancer and she is really helping her, taking care of her. What would you want your daughter to hear right now . What do you want her to know . We are waiting for her at home. I want people to know that those are innocent people that were just wanting to have fun and they just were slaughtered and killed. Hundreds of people are missing. And my best friend is one of them. We want to bring her back as soon as possible. We need all of the kidnapped people here. Most of the estimated 150 hostages were taken from the festival in small farming communities very close to the gaza border. Weve all seen the videos of hostages being taken away. Most likely they went back into gaza the same way that they came out through the breaches in the fence. There is really no other way to get in or out. We dont know the exact number of hostages taken from the festival. This mother saw her daughter in this sickening video. She had been stripped and appeared unconscious, lying in the back of a Pick Up Truck with one gunmans leg draped over her waist and another holding a clump of her hair. A mob shouted, god is great, and someone spat on her. Her mother is determined to find her. I mean, after the video we really couldnt be sure if she survived the way she was thrown on the pick up it looked really bad. Could hardly recognize her. We all started crying, my son, my family, started crying and screaming. That was really horrible. We know that they tried to her credit card in the afternoon from the gaza strip and then in the night they tried to use it again. Days later she said someone told her her daughter might still be alive. She wouldnt say who it was. We heard information that she is alive and she has a bad head injury and nis in the hospital. Thats all we know and that gave us hope. Coming up, Surviving The Festival Massacre i heard bullets whistle near my head and ears. And i looked around me and i realized i can out run them i cant out run them. I thought if the birds cant see me hamas cant see me either. As hamas gunmen roamed the Festival Grounds slaughtering unarmed civilians many party goers tried to escape on foot. They realized hamas was on the road both on the north and the south. They abandoned their vehicles and just started running across the highway and through the open field. I heard bullets whistle near my head and ears. And i looked around me and i realized i cant out run them. We ran for five hours in the fields. One of my friends were barefoot. We tried to call the police. And i remember clearly she told us, youre surrounded everywhere. In every living area there is shooting. There is gunshots. There is killing. I dont know when cops will be there to help you because all of my cops are already dead. If you havent got shot yet then you are lucky and just hide. Just hide. They hid in the sparse bushes and shrubbery in fields outside the Festival Grounds. Some sent messages to loved ones and took photos like this one thinking it might be their last. This couple
