in september 2013, al shabaab, an al qaeda-linked terrorist group from somalia, attacked a shopping mall in neighboring kenya. more than 100 security cameras recorded the attack, which left 71 people dead. some of the footage was destroyed by fire, but much of it survives, and it documents the attack in stark detail. but it also reveals something else, the courage and resilience by which so many ordinary civilians survived mass murder in a crowded shopping mall.

>> it was one place where you meet people of different cultures, different tribes, different religions, different anything. just all special things. >> at the front of the mall overlooking the street were three busy restaurants. urban burger, tapas, and art cafe. >> it has the best in nairobi. it was a very up market. it's a place where prominent people come. >> at the back of the mall was a giant supermarket on two floors. nakumatt's westgate was the premiere supermarket in nairobi. it had an escalator. it was a huge thing for kenya to have an escalator inside a supermarket. and they sold everything you might need, and that was always

its tag line, all under one roof. >> we would be there two or three times during the week. it's more than just a mall to buy, you know, extra stuff. it was really part of our lives. >> that saturday was really a normal saturday, like any other saturday. i went with my kids, my daughter, emily, who's 6 years old, and my son, eliot, who's 4. i was quite excited, because i was doing a big shop and i tried to do all my shopping at the local supermarket, but i was finding stuff i don't normally find. i'm french and i was finding a drink you get in france and getting really excited about it. >> we were planning on getting as many groceries as we could. and we needed to do it relatively quickly, because i had a little baby who was 8 months old and he was hitting close to nap time. we took our time, but we were thinking, okay, baby's going to lose it soon, he needs to get home. >> opposite the entrance,

valentine had set up a display table for a computer company. >> i was walking. we had a display table. we have the products. so that the customer can touch and feel. >> a few feet from valentine's display table, catherine walleten stops to make a phone call. >> the kids just wanted to hang out a bit and have some lunch. i have two boys, a 14-year-old and a 10-year-old, and three little girls, 4, 2, and 13 months. >> katherine's two sons had gone shopping the in the supermarket. >> we stopped at the drink aisle, because i wanted something to drink, so i tried calling my mom for a few minutes and i gave up and we went and stood in line. >> we were there for quite a while. i think we had probably already been in there for about an hour. so the trolley was full and we

were almost finished. and i remembered i wanted to get a bottle of wine, so i left the kids by the trolley, which because in kenya, you kind of do, because you don't have that fear of your kids getting kidnapped, you know they're quite safe. >> at 12:30, andrew was at the street entrance to the mall. >> i was just sort of passing through westgate to do a few errands, buy some packed lunch, and pick up my boy and come back home, like normal. you have to go through security check. and i was at the door when i was being searched and my hands was raised up. >> i was just walking in front of the market when there was a loud explosion. >> bang! i realized they were searching me and i was falling down. >> a grenade went off, immediately followed by gunfire. you could see people falling on the floor. some were diving for cover, but

some were actually falling. >> when i dived down, i touched my chest and there was blood on my fingers. >> a couple had been having lunch on the terrace. >> i realized that my wife wasn't actually behind me. i saw her crawling on the ground, clearly in a lot of pain, her legs looked very bloodied. i took her and dragged her towards the back wall of the burger restaurant, so that we didn't have a direct line on to the road, assuming that it was a hit-and-run grenade attack, and therefore, being out of sight of the road was the important thing at that point. >> tracer routes. you know, there was that flash

of light as they were flying through the air. >> people are confused, they don't know where to go, stepping on each other. that's when i saw a white lady with three children. saw them running in different directions. that's when i picked up one. >> i started to run and a kenyan woman came and grabbed one of the girls from me and we dove behind this computer display table that was there. she had portia, my 4-year-old, and was laying on top of her to protect her. >> now georgette and a friend also squeezed in under the display table. >> my friend was lowing lady and the lady was laying like that. >> it was a tight fit with the seven of us. we were kind of lying on top of each other and all scrunched up. >> as the gunfire got closer, people surged from the main mall into the supermarket. >> as we were running, people just came and started pushing me and i had to reach my arm through just to grab his hand, so i wouldn't be separated from him. >> people were running towards

the back of the store and that's when i thought, i've got to get to the kids. because it was quite chaotic. i couldn't remember exactly which till, so it took me a while to find them, and i remember screaming to try to pinpoint where they were. >> inside, a customer's cell phone recorded the gunfire getting closer. the two gunmen were moving from the street to the restaurants by the front entrance of the mall. >> i was looking at his face. he was young and he looked at me and he fired.

as i pulled my wife behind one of the counters and as i kind of collapsed on the floor, i realized i had been shot. >> 100 feet away at doorman's cafe, two little kids had been waiting for their mother. with them was a school friend, 15-year-old. >> we knew that there were people shooting from the main entrance. i could see people were running, so we headed inside. >> there was a lull as the gunmen reloaded their weapons. waiter mike cadway saw andrew wounded and went to help him. >> i think at that point, somebody came and pulled me from the doorman's. saying, stand up. >> mike rushed andrew into the supermarket, towards the loading bays, where hundreds of shoppers were trying to escape.

the gunmen now moved from the restaurants towards the supermarket. >> we were all laying as flat as we could, behind that table you know in the beginning, i cried. i was just so scared. and the kenyan lady, you know, kind of tapped me on the shoulder and said, you can't do that, you have to be strong for your girls. >> the white lady told the little girl i was holding, put your fingers in your ear and lay down and keep quiet. >> two policeman guarding a bank on the first floor spotted the terrorists and opened fire. >> i was using my rounds to cover myself. shooting so that i could deny him a chance to shoot at me. i shot him in his right leg or his knee there. he was limping, so i knew that the guy was injured.

>> undeterred, the terrorists headed on towards the supermarket and the display table where the four women and three children were hiding. >> patra kept crying. she would really scream when the shooting would start. she would just scream and scream. i had brought one bottle of milk with me, and i gave that to her and she drank it and went to sleep. i realized that i would definitely, as being an american, as being a christian, that it was much more dangerous, probably, for me. you know, i was a prime target. >> as they shot, you could hear the sound of the bullet thud into someone, the sound of the bullet going into flesh, it's like nothing you've ever heard. >> it feel like somebody's been thumped, you know, and then they

of westgate. >> they headed towards the rooftop, where a children's cooking competition was taking place. >> what are you making today? >> we're making apple pudding with cream cheese delight and we're making -- >> we heard gunshots, we heard screaming. i personally felt that this is a robbery or something and these are thugs. they need a passage, so stay out of their way and everything will be okay. >> it's almost like we were being herded like sheep. so we went to the furthest corner of the parking lot on the roof, away from the door and the ramp, and there are a lot of people stuck in there, lots of women and children from the cooking competition. >> and suddenly we just saw people falling, one after the other. >> as they shot, you could hear the sound of the bullet thud into someone. the sound of the bullet going

into flesh is like nothing you've ever heard. >> it feels like somebody's being thumped, you know? and then they just drop. >> i looked at them, when his gun was pointing at me, and he shot me. and then i realized i was shot in the stomach as well. >> i just put up my hand and i said, please let the children go. let the children go. >> the only thing he said was that we're here to kill. you killed our people in somalia. we normally don't kill women and children, but you kill ours in somalia, so we're here to take revenge. >> i started saying a prayer, which is, there's no god but allah and mohamed is his messenger. so as soon as he heard that, the gunmen looked at me and he said, are you muslim, and i said, yes win am. by that time, my wife had come next to me. she was drenched in blood from

top to top. he said, is this your woman. and i said, yes, she is. and then he said, go. >> as they ran down the ramp to safety, the gunman released some other muslims who also survived the initial attack. >> an elderly lady stood up, encouraged to see that the gunmen was releasing people. so she said, you know, i'm old, i can't kneel anymore, my knees are arthritic, i'm in a lot of pain, please let me go. and the man asked her, are you a muslim, and while the woman was thinking of the answer to give, the gunman just shot her. >> the gunfire on the rooftop caused panic amongst shoppers trying to escape through the loading bays down below. >> they came running out of the store, back into nakumatt's supermarket, saying, don't go

that way, they're shooting that way. so we were really stuck. we didn't know we can get out the front and thought we couldn't get out the back. >> the gunman in nakumatt's made an announcement on the supermarket's public address system. >> we're going to kill everybody. you came to our land and killed our women and children, it's our time. >> where do you hide in a supermarket? anywhere where you are, you're exposed. and i kept on thinking, why now? i can't believe this is happening while i have my baby with me. >> i though the best place to hide would be behind the meat section, behind the deli counters, if you like. >> she was laying in front of me, and next door was miriana and then her younger brother. >> everybody was just lying down, facedown, and trying to move as little as possible. and i said, can i come and hide back here? and they said, sure.

and they showed me where to come in. so i kind of ducked down, still holding my 8-month-old baby. >> the security camera footage from the meat counter was never recovered. but cameras nearby show the areas to the left and to the right. >> the occasional phone would ring, and everybody would be like, turn it off, put it on silent. sometimes i would look up and the other mothers would look at me and sort of nod to each other, kind of encouraging looks to say, it's going to be okay. >> bleeding from a shrapnel wound, andrew had taken refuge in nakumatt's furniture storeroom. >> i'm starting to feel dizzy, i'm starting to feel nervous. i'm now starting to think, oh, this could be the end of ourselves, you know? i don't know whether we would be out at all.

i'm bleeding and i'm starting to fear now. and i'm thinking, this is the end now. >> he told me that he's thirsty. he wants water. and i told him to stay put and i would go look for water and i would bring it to you. >> as mike went downstairs to fetch water for andrew, the power went out. that's when one of them saw me and shot me. and i was screaming and something hit me like shut up or they might be coming and looking for you. soy kept watch and i started running. >> the minute he got to us, he collapsed. he fell down. >> to be honest, i've watched enough movies to know what to do. when someone is shot and bleeding, you apply pressure. at least to stop the bleeding. i was a little bit scared that he might succumb to his wounds,

but i didn't let that distract me from doing my best. >> it's not enough. it nearly saved my life. >> outside the mall, there is still no sign of a rescue operation. it was 45 minutes since the attack had begun. >> it felt endless. it felt like no one was coming for us and i was going to die there. the little boy next to me, screaming in agony. he'd been shot and he was screaming, they shot my mother, why did this have to happen? why did they do this? screaming and screaming.

as the lights came back on, the first pair of gunmen headed for the meat counter, where 20 people were hiding. >> i told the lady that someone was coming, i could see the reflection of someone coming. >> she was shaking saying, they're coming, they're coming, and i was like, shh, thinking they would walk past, but they came straight to where we were and very deliberately, they shot everybody around us. i never looked up, i never saw anything, but it was just the sound of just. >> they say now it is your time. we have come for you. you know, as they were shooting, children were screaming, as they were shooting. >> i just felt some pressure. but when the person walked away, i looked and could see that i was shot. >> it was a really strange

physical force. and i found out later that i was shot in the -- in my left leg, it entered in my left leg and came out by my right hip. my main concern was to make sure my children didn't see anything. it was a lot of blood and a lot of anguish on people's faces as they lay there dying. >> 200 feet away, katherine and her three daughters were still hiding under the display table. >> i was worried that my girls, you know, if they were to get shot, that i would have to lay there and watch them die or if i were to get shot, they would have to lay there and watch me die, and i didn't want them to have to go through that. >> there was a doorway of

nakumatt's. and i asked him, what's going on? and he told me, lie down. that's what he told me. because from there, he could see the other direction that i could not see. >> the second pair of gunmen came down from the rooftop and shot anyone they found. >> he was beeping, beeping. why did he think of hiding in the elephant? anyone could see you. i'll never understand, for the rest of my life. i'll always remember that guy.

>> inside nakumatt's, the four gunmen regrouped. they had murdered several dozen people so far. outside the mall, there was still no sign of a rescue operation. it was 45 minutes since the attack had begun. >> i got the call and they said, don't go to westgate, there's a robbery and they're killing people. >> veteran war photographer of reuters news agency shot rapid bursts of pictures as he moved past the terrorists' car and found the victims of the first few minutes of the attack. >> he was coming out of one of the barracks. it was very real seeing those people, the music you could hear

in the elevators, you know. >> a handful of police had arrived, but the sound of heavy gunfire had kept them out of the mall. amber lay behind the meat counter with her children, bleeding from a bullet through the pelvis. >> it felt endless. it felt like no one was coming for us and i was going to die there and i was going to die there on top of my children and what would happen to them? and then the boy next to me, screaming in agony. he'd been shot and he was screaming, they've shot my mother, why did this have to happen? why did they do this? and screaming and screaming and i was trying to calm him down. at some point, the sister also passed away. people were screaming, stop screaming. eventually, you could, you know, as they died, and so it became quieter >> a driver for an american

charity was still alive. >> he had seven gunshots. they shot him and once they realized he didn't die, they still come and shoot him once again. so very painful. it's a person to looked to solve issues, not violence. he was humble. >> in the burger restaurant, it had now been 50 minutes since neil and his wife had been shot. >> her legs had been pretty

badly shredded and she was losing quite a lot of blood. my shoulder and arm had been very badly hit. i had, you know, holes big enough to put fingers inside. and with the blood i was losing myself, it was harder to stay conscience the whole time. she was clearly on the edge and shaking from what must have been blood loss, in retrospect. clearly in a lot of pain, clearly very, very scared. i tried to move closer to her at that point, took her hand at one point, and at some point, i'm pretty sure she died.
