Terrified eyewitnesses who survived the Manchester Arena terror attack have described the horrifying scene last night - with one teenager saying: 'People's skin and blood were everywhere'.

Homeless people outside the venue were 'pulling nails out of children's faces' and 'cradled victims in their arms' after an improvised explosive device was detonated.

At least 22 people - including children - were killed and 119 people were injured just as Ariana Grande finished her set on Monday evening.

Schoolgirl Saffie Roussos, eight, 18-year-old Georgina Callander and John Atkinson, 26, have all been named as victims of the terror attack at the pop concert.

Petrified parents clung on to their children as they sprinted out from the venue as the 'callous terrorist attack' took place.

One eyewitness, Abby Mullen, 17, was inside the arena where a suspected lone wolf attack took place and described finding blood in her hair.

Meanwhile, a homeless man tearfully described the moment he cradled a dying woman in his arms after the suicide bomber blew himself up.

Police this morning confirmed the suicide bomber died inside Manchester Arena after an improvised explosive device was detonated at the end of the gig.

A homeless man, called Steve, described the moment he had to 'pull nails out of children's faces' following the shocking attack.

He said: 'Just because I'm homeless it does not mean that I haven't got a heart and I'm not human still.

'They needed the help and I would like to think someone would come and help me if I needed help.

'It's your instinct to go and help and it was children and it was a lot of children. We were pulling nails out of their arms and from a little girl's face.

'It had to be done, you had to help. If I didn't I wouldn't be able to live with myself for walking away and leaving kids like that.'

Ms Mullen, from Airdrie, North Lanarkshire, was inside the venue and said: 'As we were leaving a bomb or explosion went off centimetres in front of me.

'People's skin, blood and faeces were everywhere including in my hair and on my bag.

'I'm still finding bits of god knows what in my hair. You never ever expect these things to happen to you but this proves it can happen to anybody.

'That sound, the blood and those who were running around clueless with body parts and bits of skin missing will not be leaving my mind any time soon or the minds of those involved.'

Horrifying footage showed petrified children leaping over fences as they desperately tried to escape the 21,000-capacity venue.

Ms Mullen's mother, Lisa Kane, said her daughter's high heels saved their lives because Abby's shoes made the journey to the exit take longer.

She said: 'As soon as it happened I knew it was a bomb. It blew back into the arena – both sound and force from the blast.

'I don't know how we're alive. I've not got a mark on me and I just don't know how. There was a woman lying next to me and I'm pretty sure she was dead.'

The pair planned to leave during the final song to beat the rush of the crowds.

Ms Kane added: 'As it was the final song I said to Abby 'why don't we start walking before the crowd starts building?'

'Abby had high heels on so she walked in front of me while I held her waist to steady her.

'That's why we're alive - because she was wearing the high heels she wasn't moving as fast - that saved us.

'As we got to the top through the doors we got flung back in. Everyone was screaming and running.

'A steward came up to me and told us to run back down the stairs. People were scared to move in case someone had a gun. I just told Abby to take her shoes off and run down the stairs.'

Rough sleeper Chris Parker, 33, was in the foyer area - just yards from where a man detonated an improvised explosive device which killed at least 22 people.

He typically waits there to ask people for money as concert crowds head home and described seeing a little girl 'with no legs' following the Ariana Grande concert.

Mr Parker saw people 'lying on the floor' and said a woman in his 60s 'passed away in his arms' outside the building.

He said: 'Everyone was piling out, all happy and everything else. As people were coming out of the glass doors I heard a bang and within a split second I saw a white flash, then smoke and then I heard screaming.

'It knocked me to the floor and then I got up and instead of running away my gut instinct was to run back and try and help.

'There was people lying on the floor everywhere.

'I saw a little girl - she had no legs. I wrapped her in one of the merchandise T-shirts and I said 'where is your mum and daddy?' She said 'my dad is at work, my mum is up there'.'

He said he thought the child's mother had died from her injuries following the incident which left at least 119 people injured.

Mr Parker, who has slept rough in the city for about a year, said he also tended to a woman aged in her 60s who was badly hurt from the bombing with serious leg and head injuries.

He told ITV News: 'She passed away in my arms. She was in her 60s and said she had been with her family.

'I haven't stopped crying. The most shocking part of it is that it was a kids' concert.

'There were nuts and bolts all over the floor. People had holes in their back.

'It's the screams I can't get over and the smell ... I don't like to say it but it smelled like burning flesh.

'I don't think anything has sunk in yet. It's just shock.'

The Queen expressed her 'deepest sympathy' to all those affected by the Manchester bomb attack, adding that 'the whole nation has been shocked by the death and injury'.

On Tuesday, police cordoned off the area surrounding the Manchester Arena following the incident last night

The blood-soaked pair managed to hail a taxi and go back to their Lowry Hotel room.

She added: 'We were covered in blood so when we got back to the hotel we had showers.

'Abby came out of the shower and sat on the floor crying saying 'there's something in my hair'. It was a bit of someone's flesh. It was just awful.

'Abby's traumatised and is still in bed – she doesn't want to talk about it.'

A pregnant teenager was forced to 'run and run and run' after the bomb exploded inside the venue just after 10.30pm last night.

Heidi Berkeley, 18, who is eight months pregnant, was at the concert with her 16-year-old sister Kate.

The pair, who had been bought the tickets by their mum Annie Berkeley-White, sprinted to the centre of the city as chaotic scenes unfolded around them..

Heidi, of Nottingham, said when she saw groups of girls screaming and running she thought they had spotted pop star Ariana.

She said: 'We got there and she (Ariana) was amazing. We were leaving through a fire exit and we heard a massive bang, it shook the whole building.

'At the time we thought it was someone popping a balloon near us. We got out and saw people running and lots of girls screaming, but we thought they were just excited as they'd seen their idol.

'We went to buy a poster from a street vendor and we kept catching snippets of conversations about bombs and heard one guy saying to get somewhere safe.

'I just remember grabbing my sister and pulling her, running down the street as far as we could.

'I heard bomb and thought we've just got to get out of here. I'm eight months pregnant but I couldn't think about anything but running. We ran and ran and ran.

'It was so scary. I've never seen my mum so happy to see us before, I don't think I've ever hugged for as long as I did.

'It feels really surreal. All these 'what ifs' are going through my head. I'm just so grateful we got out when we did.

'It's so horrible to think what happened to people just because they went to see their favourite artist.'

Meanwhile, the mothers of two girls caught up in the atrocity have spoken of the moment they grabbed their children's hands and 'literally ran for their lives'.

Amy Hill, 13, and Hayley Lunt, 10, were in the arena when the killer struck. It was the first time the younger girl had been to a live performance, her mother said.

She told MailOnline: 'It's her first concert. After that, I don't think she'll want to go to another because she and myself were both absolutely terrified.

'When the bomb went off, it took a few seconds before anybody realised that something serious had taken place.

'I heard two bangs. They didn't sound loud enough to be explosions. I thought they were either balloons or a speaker.

'I didn't think for one minute there had been an explosion. Then, very quickly I could hear screams and I grabbed my daughter's hand and we literally ran for our lives.'

Amy Hill's mother added: 'The concert was coming to an end and we had had a fantastic evening. We began to walk up the stairs for the exit.

'The doors were open and we heard this very loud explosion. I didn't think it was a bomb. I carried on walking up the stairs normally and then all of a sudden I could hear screams and everybody started to run in sheer terror.'

Eyewitness Jane Hanson, 44, was watching the concert from a box inside the packed arena with her 16-year-old daughter Andrea.

She told MailOnline she heard a 'massive bang' and saw a 'stampede' of people sprint out of the venue with one girl shouting 'I don't know where my sister is'.

She said: 'We were just getting ready to leave and there was a massive bang below. We initially thought it came from the stage but then we saw smoke below us.

'I saw children hysterically crying and panicking. One man was carrying children in his arms.

'One girl was ran outside the venue and was shouting 'we don't know where my sister is'. Children were just running for their lives. It was blood-curdling.

'It seems that the explosion happened at the front and those who decided to get up and leave just as it finished would have been caught up in the incident.

'When we left the box it was terrifying. We didn't know which way to turn and I was scared that we would walk down the wrong path.'

Gary Walker, from Leeds, West Yorkshire, was with his wife in the foyer waiting to pick up his two daughters who were at the concert.

He said: 'I was waiting for the kids to come out. We heard the last song, and quite a few people were flooding out and then suddenly there was a massive flash and then a bang and smoke.

'I felt a bit of pain in my foot and my leg. My wife said, 'I need to lie down'. I lay her down, she'd got a stomach wound and possibly a broken leg.

'I was about three metres from the actual explosion. I am surprised I got away so lightly.'

He added his wife was taken out of the building on a table used as a 'makeshift stretcher'.

Mr Walker said the explosion was by the door in the foyer, next to the merchandise, and that glass and metal nuts were left on the floor.

He told the Star: 'The nuts must have been packed in the device that's exploded - there's nowhere else they could've come from.'

His daughter Abigail, who was still in the arena with sister Sophie at the time of the explosion, said: 'I had to make sure I had my sister. I grabbed hold of her and pulled hard.

'Everyone was running and crying. We were just trying to figure where everyone was. It was absolutely terrifying.'

Abigail and Sophie contacted their parents by mobile phone, a moment Mr Walker described as 'fantastic news'.

A 49-year-old mother, who asked not to be named, attended the concert with her 13-year-old daughter and was just 'three metres' away from the bomb.

She said it is a 'miracle' she is still alive and revealed the only reason she survived was because people 'blocked the impact' of the blast.

The woman, from Manchester, told MailOnline: 'We were in the foyer and had just left the concert after she finished her last song.

'The blast had a ripple effect and it pushed us forward. I immediately knew it was a bomb and wanted to get out of there as quickly as possible because I was with my daughter.

'It is a miracle we are still here because we were just three metres away from the explosion. I remember there being a flash of orange and then white.

'We ran outside and jumped into a taxi and the driver offered to take us back to our house for free.

'Workers at the arena, who were young men, were incredibly brave and ran towards the area where the explosion took place to help people.

'We survived because sadly the people closer to the explosion blocked the impact of the blast.

'The people who were going to the car park are likely to be the people who are unaccounted for.'

David Richardson was at the gig with his 13-year-old daughter Emily. He said: 'The lights came on after the gig and people were starting to leave.

'As I turned to the left there was an explosion. It was about 40ft behind us near one of the exits.

'We just thought it was people messing about then it happened again. Another explosion sounded.

'Then we saw the smoke. Everyone just fled. Some people were injured. We saw blood on people when we got outside. People were just running all over the place.

'People have said it was a speaker or balloons but it wasn't. It was explosions.'

Another man who took his daughter to the gig said: 'Ariana said: 'Bye bye Manchester!'

'The lights came on then there was two big noises and people started running and shouting.

'We got in a lift to go up to the next floor to the exits. When the doors opened I saw blood on the floor and two injured people.

'Blood all over their faces. A lot of people were in shock.'

Eyewitness Sasina Akhtar said: 'She did her last song, we were in the lower tier and there was an explosion behind us at the back of the arena.

'We saw young girls with blood on them, everyone was screaming and people were running. There was lots of smoke.'

He said: 'It was just panic and people running. No one knew what was going on and there was an awful lot of screaming.'

There was a bang, a weird bang. There were lots of balloons but I thought to myself that can't be a balloon, that's not normal.

'We were sat on the floor level and it came from the higher seats, people were running and screaming.

'Everyone stopped and I turned to my friend and said 'we need to run'. Everyone was running and screaming and then when we got out it felt a bit more OK.

'I heard five or six bangs that sounded like gunshots. When we got outside people were outside, crying and on their phones.

'You don't think it's something that's going to happen when you go...it was such a nice, fun concert.'

Nick Schurok, 28, from Manchester, told MailOnline: 'Ariana Grande had just finished the concert and the lights came on.

'Everyone started leaving. I was on the floor and at the back of the arena people started exiting through the tunnels.

'There was a bang in the left tunnel and everyone went to the middle tunnel. Then about two minutes later, there was another bang.

'The bang was so loud and crowds of people were running. There were lots of children and families there.'

Another witness Jenny Brewster told MailOnline: 'We were exiting the building when it happened.

'We'd headed towards the main doors as Ariana was performing the last song because we wanted to beat the crowds, but – as we made our way there - a wall of security men blocked it and told us to go the other way.

'Seconds later they shouted 'RUN!' and the explosion happened right behind them. Hundreds of people were running and screaming. Those men saved our lives.'

Isabel Hodgins, an actress who had been attending the concert, told Sky News: 'Everybody was panicking, there was pushing up the stairs.

'The corridor was full, it smelled of burning, there was quite a lot of smoke as we were leaving.

'It's just shocking and we just feel very shaken up. We're just lucky to have gotten away safely,' she said.

Catherine Macfarlane told Reuters: 'We were making our way out and when we were right by the door there was a massive explosion and everybody was screaming.

'It was a huge explosion - you could feel it in your chest. It was chaotic. Everybody was running and screaming and just trying to get out of the area.'

Erin McDougle, 20, from Newcastle, said: 'There was a loud bang at the end of the concert. The lights were already on so we knew it wasn't part of the show.

'At first we thought it was a bomb. There was a lot of smoke. People started running out. When we got outside the arena there were dozens of police vans and quite a few ambulances.'

A group of young men from Sheffield said they had seen at least five people covered in blood and others being carried out by bouncers.

'Ariana Grande had just gone behind the curtain and the lights came up when there was this massive bang and a big cloud of smoke. I saw five people with blood all down them,' said one.

Robert Tempkin, 22, from Middlesbrough, told the BBC: 'Everyone was screaming and running, there were coats and people's phones on the floor. People just dropped everything.

'Some people were screaming they'd seen blood but other people were saying it was balloons busting or a speaker had been popped.

'There were lots of ambulances. I saw somebody being treated. I couldn't tell what had happened to him.'

He said: 'I was in the toilet and heard a loud bang just after the concert had finished and people had started to leave.

'The bang echoed around the foyer of the arena and people started to run.

'I seen people running and screaming towards one direction and then many were turning around to run back the other way.

'Security was running out as well as the fans and concert goers. Reports of blood and people injured.'

He added: 'In so much shock and panic. You see this on the news all the time and never expect it to happen to you. I just had to run and make sure me and my sister were safe.'

Majid Khan, 22, said: 'We were all exiting the venue when around 10.40-10.45pm-ish a huge bomb-like bang went off that hugely panicked everyone and we were all trying to flee the arena.

'It was one bang and essentially everyone from the other side of the arena where the bang was heard from suddenly came running towards us as they were trying to exit Trinity Way and that was blocked so everyone was just running to any exit they could find as quickly as they could.

'Everyone was in a huge state of panic, calling each other as some had gone to the toilet whilst this had gone off, so it was just extremely disturbing for everyone there.'

Another concert-goer Laura, 22, told MailOnline: 'There was a woman leaning against a car in the car park with her head down, covered in blood and a little girl being lifted away by paramedics. There were quite a few people injured in the car park.'

'It was just when we were leaving. We saw a flash of light and smoke.

'We're really shaken up. If we had been there moment earlier we would have been caught up in it rather than seeing it.'

Erika Ignata, 18, from Cheshire, was at the concert with her 26-year-old sister, Monica.
