More than 58 people have been killed and around 400 injured at an open-air country music festival in Las Vegas in the deadliest mass shooting in US history.
Terror spread through the city's famous strip as 64-year-old gunman Stephen Paddock launched an attack from the 32nd floor of the Mandalay Bay Hotel and Casino, unloading hundreds of rounds of ammunition from a cache of weapons towards concert-goers.
Police confirmed the attacker shot himself dead just as a police SWAT team burst into the hotel room from where he sprayed rapid fire on the crowd for several minutes.
Described as a "lone wolf" who lived in a remote desert retirement village, Paddock was holed up with more than 10 guns after he is believed to have checked into the hotel on Thursday.
The attacker's motive is unknown, but police believe he acted alone. They said he is "not believed to be connected to any militant group" despite a claim of responsibility from Islamic State, adding: "We have no idea what his belief system was."
Addressing the nation on Thursday afternoon, US President Donald Trump described the shooting as an "act of pure evil", adding that he would visit emergency services in Las Vegas on Wednesday.
The Las Vegas sheriff had earlier been seeking Paddock's female "companion", Marilou Danley, as a "person of interest". After she was located overseas, police said the 62-year-old - who is believed to have lived with Paddock - was not involved in the shooting.
An estimated 22,000 people dived for cover as hundreds of rounds of shots rained down on the crowd during the Route 91 Harvest Festival at shortly after 10pm on Sunday local time (6am Monday BST). An off-duty police officer was among the dead.
Las Vegas police said officers found more than 10 guns in the attacker's hotel room after entering to find he had fatally shot himself.
The shooting came towards the end of the three-day festival while headliner Jason Aldean, the American country music singer, was on stage.
Mr Aldean posted on Instagram that he and his crew are safe, as he said: "My thoughts and prayers go out to everyone involved."

British survivor tells of horror of Las Vegas attack
A British survivor of the massacre has told how she threw herself to the floor to dodge the gunman's bullets.
Samantha Evans, 36, watched in horror as a security guard was shot just feet from where she was standing.
Ms Evans, a holiday rep, said: "At first I thought it was fireworks but then I heard screams as people were being shot.
"We all ducked down as low as we could, I was on the floor. It went on for 10 minutes but it felt like forever."
Ms Evans had taken her mother, Charley Wilson to the Las Vegas country music festival as a treat for her 60th birthday.
Mrs Wilson was sitting on her mobility scooter along with 30 other disabled people on a raised platform for a better view.
"When I heard the loud bangs I thought 'that's cool' they are putting on fireworks for the last night of the festival," Ms Evans said.
"But then there was a sudden wave of panic and we realised everyone was being shot at.
"The gunfire sounded really close, we just ducked down and prayed."
Ms Evans and her mother, who are from Cardiff, were being led off the platform when she saw the shot security guard.
She said: "He was less than 10 yards away from us - that's how close we were.
"I don't know if he was dead - we were just trying to get off where we were standing as quickly as we could.
"My mum was freaking out - it was a raised area and more exposed... The Americans all around us were brilliant.
"They could see mum was on a disabled scooter but they lifted that over the bars and then carried her over as well."
'Donald Trump has picked his side in America's gun control culture war. Las Vegas will change nothing'
Rob Crilly writes:
When Donald Trump addressed the nation in the aftermath of the country’s latest and most deadly mass shooting, he managed, for once, to set aside the differences and divisions that propelled him to power. He remembered that in times of darkness his role is to be the consoler-in-chief.
“In moments of tragedy and horror, America comes together as one…. we call upon the bonds that unite us – our faith, our family and our shared values. We call upon the bonds of citizenship, the ties of community and the comfort of our common humanity,” he said.
“Our unity cannot be shattered by evil, our bonds cannot be broken by violence, and, though we feel such great anger at the senseless murder of our fellow citizens, it is our love that defines us today and always will forever.”
It was what the nation needed from its president. There was no room for politicking. That would have been wrong.
What a contrast, it might seem, with the advocates of gun control, who showed no such reticence in rushing to make the case for tightening legislation. Hillary Clinton pointed out on Twitter that the crowds in Las Vegas began running at the first sound of gunshots at a time when the National Rifle Association is trying to make it easier to buy silencers.
“Our grief isn't enough,” she wrote. “We can and must put politics aside, stand up to the NRA, and work together to try to stop this from happening again.”
But hang on. Isn't this the Donald Trump who responded to the failed Parsons Green bombing last month by touting his stalled travel ban and demanding terrorists be “dealt with in a much tougher manner”? Isn't it the Trump who responded to the Orlando nightclub shooting, America's most deadly gun massacre until this one, by noting that he had predicted such an attack and blaming it on Barack Obama and Hillary Clinton?
If that isn't politicking after a tragedy, nothing is. What gives?
Vladimir Putin: Las Vegas shooting is 'shocking in its cruelty'
Vladimir Putin has sent condolences to his US counterpart Donald Trump, the Kremlin said in a statement.
"This crime which killed tens of peaceful citizens is shocking in its cruelty," the statement quoted Mr Putin as saying in a telegram to Mr Trump.
Trump to visit Las Vegas
Donald Trump has announced that he will visit Las Vegas on Wednesday morning.
"We're going to be seeing the governor of the state, who I just spoke to, the mayor," he said. He praised the sheriff, "who has done such a great job. The police department has done such a fantastic job in terms of the speed, and we all very much appreciate it."
Mr Trump will be in hurricane-struck Puerto Rico on Tuesday, and arriving in Nevada on Wednesday morning.
There will be a minute's silence for the victims at 2.45pm Eastern Time on Monday.
Las Vegas gunman Stephen Paddock had made significant gambling payments in recent weeks, it has been reported.
Officials say that Paddock's payments were in the tens of thousands, but it was not clear whether those were losses or wins.
His former neighbours in Florida, Don and Sharon Judy, said that Paddock was a "night owl" who spent his evenings gambling.
"He did video gambling when he was here," Mrs Judy said. "He showed me one time on his iPhone how he had just won $20,000."
She added that he said he "gambled for a living".
First victim identified
Sonny Melton, a registered nurse from Paris, Tennessee, was killed on Sunday night while protecting his wife, his family told WZTV.
"At this point, I'm in complete disbelief and despair," Mr Melton's wife Heather Gulish Melton, said on Monday.
"I don't know what to say. Sonny was the most kind-hearted, loving man I have ever met.
"He saved my life and lost his."
According to his Facebook profile, he worked at Jackson-Madison County General Hospital in Jackson, Tennessee.
New photograph of gunman emerges
A new picture of Stephen Paddock has emerged.
It is unclear when it was taken.
Pleas for blood
County representative Dina Titus said that prayers were welcome, but there was a pressing need for blood donations, saying: “We need blood.”
Mayor Carolyn Goodman launched an emotional plea for Nevadans to donate blood to help those injured in Sunday night's attack.
"What we ask for is blood," she said. "If our people want to do something, and they are healthy, then please donate blood. We'll have plenty of banks available. Always call a hospital if you're not sure."
Condemnation for gunman
The Clark County district attorney, Steve Woodson described the gun used as "a classic WMD. This was a weapon and a man of mass destruction."
He added: "This doesn’t involve politics - all of us are Nevadans."
The mayor, Carolyn Goodman, condemned the attacker as a "crazed lunatic full of hate".
Police add that the death toll may be set to reach 59.
Death toll rises
Fifty-eight people are now known to have been killed in a mass shooting at an open air concert in Las Vegas while another 515 were wounded, police said Monday.
"The number of people who have died associated with this event has increased. Right now we're using the number of 58," Las Vegas Sheriff Joseph Lombardo told reporters.
"The number of injured - we are using the number of 515."
Isil may have claimed the terror attack via their publication, Al-Amaq, but this was refuted at the press conference on Monday.
An FBI special agent said: “We have determined at this point no connection to international terrorist organisation.”
The consoler-in-chief urges US to unite in its grief
Donald Trump appeared in his role as consoler-in-chief as he urged the country to unite in its grief and to banish evil, reports Rob Crilly.
“Hundreds of our fellow citizens are mourning the sudden loss of a loved one, a parent, a child, a brother or sister", he said. "We cannot fathom their pain, we cannot imagine their loss.
“To the families of the victims: We are praying for you and we are here for you, and we ask God to help see you through this very dark period.
“Scripture teaches us the Lord is close to the broken-hearted and saves those who are crushed in spirit. We seek comfort in those words for we know that God lives in the hearts of those who grieve.”
Donald Trump: Las Vegas shooting was 'act of pure evil'
Speaking to the nation from Washington, US President Donald Trump said: "It was an act of pure evil."
After thanking emergency services for "finding the shooter so quickly", he added: "Hundreds of our fellow citizens are now mourning the loss of a loved one."
Mr Trump added he will visit Las Vegas on Wednesday to meet emergency services and the families of victims.

Eric Paddock, the brother of Las Vegas attacker Stephen Paddock, told CBS News his brother was "not an avid gun guy at all".
He added: "The fact that he had those kinds of weapons is just... where the hell did he get automatic weapons? He has no military background or anything like that.
"He's a guy who lived in a house in Mesquite and drove down and gambled in Las Vegas."

Broken windows on 32nd floor of Mandalay Bay hotel

Pictures showed two smashed windows on the floor from which gunman Stephen Paddock sprayed bullets at concert-goers below.
Islamic State claims responsibility for attack
The Islamic State's news agency has claimed responsibility for the concert attack, alleging that Stephen Paddock was a "soldier" and converted to Islam "months ago", without providing any evidence to support the claim.
Police in Las Vegas state that there is no link to international terrorism and have said they do not believe the suspect was connected to any militant groups.
Trump set to address the nation at 3.30pm
Donald Trump is due to speak following the Las Vegas shooting, the White House said. The US President is set to address the nation at about 3.30pm BST.

Gunman's brother: 'He was just a guy... he snapped or something'
The brother of gunman Stephen Paddock has said the family is "dumbfounded" by what happened.
Eric Paddock told MailOnline from his home in Orlando, Florida: "He was just a guy. Something happened, he snapped or something."
US records show Paddock lived in a three-year-old, £300,000 two-bedroom home in the tiny desert community of Mesquite, 80 miles north east of Las Vegas, near the Arizona state border.
The house is currently being searched by detectives, Clark County sheriff Joseph Lombardo told reporters.
Paddock is believed to have killed himself before a police SWAT team burst into his room at the Mandalay Bay Hotel and Casino, where at least 10 "rifles" were found, he added.
He said: "We have no investigative information or background associated with this individual that is derogatory.
"The only thing we can tell is he received a citation several years ago, and that citation was handled as a matter of normal practice in the court system."
Local media said Paddock had also previously lived in Reno, Nevada, California and Florida.
He lived in the property in Babbling Brook Court with Marilou Danley, 62, records show.
She was named as his "companion" and initially as a person of interest by police. But Sheriff Lombardo later said she was out of the country at the time and they did not believe she was involved.
Video: Witnesses describe terrifying moment gunman opened fire

'Gunshots kept coming closer and closer': Barmaid relives terrifying ordeal
Kat Phifer, who was working as a barmaid at the Route 91 Harvest Festival, has posted a terrifying account on Facebook of how the attack unfolded. She wrote:
"The headliner was performing and maybe on the third song. We heard what we thought was fireworks.
"We all looked towards where it was coming from, Mandalay Bay. I saw gun fire and everyone immediately fell to the floor. Machine gun.
"It was me and three other people hiding behind the bar that I was working at. We were freaked out and didn't know what to do and also in clear view of the shooter.
"So we decided to crawl/run to another bar. Hid under a bar. Four of us girls. Hyperventilating. Scared for our lives.
"Gunshots kept coming closer and closer and we were all trying to keep quiet. Five seconds paused, then another round of shots. Closer and closer.
"I was scared for my life. I was waiting for the bullets to hit us. Finally, the cops are yelling for us to run and leave. I run and lose all the girls I was with.
"While I'm running I see about five to seven people on the floor bleeding with people huddling around them. It was a massacre. I'm running for my life hoping not to get shot.
"Call my boyfriend, frantic, to pick me up while I walk towards MGM and found my friend. So happy we're both safe, cried, then walked towards to where my boyfriend was picking us up.
"This was traumatizing and I'm still in shock. I'm sad for the ones who died and the ones who are injured. I feel so sorry for their families and friends.
"I'm glad I'm safe and still alive. Thank you for all my friends and family who called to make sure I'm safe. I love you all."
Marilou Danley is no longer 'person of interest'
Las Vegas police say they have determined that a woman they were seeking is no longer considered a "person of interest" in the deadly mass shooting.
Officials say they do not believe 62-year-old Marilou Danley was involved in the shooting.
Danley is believed to have lived at the same address as Paddock, a remote dessert retirement village, since January 2017.
Who is Marilou Danley?
Las Vegas police said Marilou Danley, 62, lived with Paddock in Mesquite. She is reportedly an Australian citizen, reports Jonathan Pearlman in Sydney.
According to The Australian newspaper, Danley, who has been located by police, is an Australian passport holder and might be of Indonesian descent. However, authorities in Australia have not yet confirmed that she is Australian.
Public records show she lived at the same address as Paddock since January 2017. A LinkedIn account for a Marilou Danley, of Reno, Nevada, describes herself as a gambling and casinos professional.
Sheriff Lombardo said: "She is an Asian female, approximately 4ft 11in, weight of 111lbs."
Authorities have not suggested she played a role in the shooting. They have also not said if she was seen with the suspect at the Mandalay Bay hotel or elsewhere prior to the shooting.
Marilou Danley’s Facebook profile said: "Proud mom and grandma who lives life to the fullest.”
Who was Stephen Paddock and what was his motive?
The gunman responsible for the worst mass shooting in modern US history is believed to be a grandfather who lived in a remote desert home, reports Leon Watson.
Stephen Paddock, 64, was named by police as the perpetrator who left more than 50 dead. He was killed when officers blasted their way into his hotel room.
Where was he from?
Paddock is reported to have lived in a retirement village in Mesquite, Nevada, since June 2016 and was born on April 9, 1953.
It is claimed he previously lived in Reno, Nevada, from 2011 to 2016, and also had an address in Melbourne, Florida, from 2013 to 2015.
He has also lived in Henderson, Nevada, and several locations in California since 1990, it is reported.
Mesquite is located about 80 miles, or an hour and 16 minutes, away from Las Vegas, along Nevada’s border with Arizona.
Mesquite, a city in Clark County, is home to about 17,400 people, including several retirement communities, along with casinos and golf courses.
Did he act alone?
Despite initial reports of multiple gunmen, police do not believe at this time that there were any other attackers.
Sheriff Joseph Lombardo, of the Las Vegas Metropolitan Police Department, described Paddock as a "lone wolf".
Officers were initially seeking his travelling companion - Marilou Danley - who has now been located. She is believed to have been his roommate.
At this stage, Paddock does not have any known ties to terrorist organisation and no motive has been put forward.
When asked by a reporter if it was an act of terrorism, Sheriff Lombardo said: “No, not at this point. We believe it was a local individual. He resides here locally.
"I’m not at liberty to give you his place of residence yet, because it’s an ongoing investigation, we don’t know what his belief system was at this time. … Right now we believe he is the sole aggressor at this point and the scene is static."
Was Paddock known to authorities?
NBC reports that he was. But public records do not show any criminal convictions for Paddock in Nevada.
Mesquite Police told CBS News that he was not known to them, and that he lived in a retirement community, is a white male and wasn't a military veteran.
What was his motive?
He was not believed to be connected to any militant group, Clark County Sheriff Joseph Lombardo told reporters.
"We have no idea what his belief system was," Lombardo said. "We've located numerous firearms within the room that he occupied."
Tennis star Laura Robson caught up in gun attack
Laura Robson, the British tennis player, has told of her shock at being caught up in the Las Vegas shooting.
The 23-year-old, who was in the crowd for the country music concert, described how "everyone started running".
In a post on social media, she said: "I'm okay. We were right there... sounded like fireworks at first then everyone started running. Scary.
"My friend who was deeper in the crowd has been helping people who were shot. We're all in shock."
Boris Johnson: 'Britain stands with American people against this indiscriminate violence'
Foreign Secretary Boris Johnson said: “I am horrified by the awful attack at a music festival in Las Vegas this morning.

“The Foreign and Commonwealth Office is in contact with Las Vegas authorities to establish whether any British people were caught up in the attack and we are ready to help however we can.
"Any British people in Las Vegas should follow the instructions of local authorities.”

'It sounded like fireworks going off': Witnesses tell of chaotic scenes
A concert-goer told how he heard what sounded like fireworks while watching Jason Aldean on stage - before the terrifying realisation they were in fact rounds of automatic gunfire.
Kodiak Yazzie, 36, said the music stopped temporarily and started up again before another round of "pops" sent the performers ducking for cover and fleeing the stage.
As the 40,000 fans in the crowd began to flee, Mr Yazzie took cover and said he saw flashes of light coming from the Mandalay Bay hotel tower high above.
He said that bursts of gunfire could be heard for more than five minutes.
Another witness told ABC: "I was at the concert there and Jason Aldean was playing, it kind of sounded like some fireworks going off.
"I think there was the first volley, and in the second volley my buddy was like 'I just got hit', got hit three times, and people started diving for the ground and it was pretty much chaotic.
"Lots of people got hit, it took a while to get them out, we got to get them over the fence and hiding under the stage for a while to be safe.
"Finally we had to move him because we had three chest wounds. Finally we got them out here, we got four people in the back of a truck but we had to turn them around because there was an active shooter.
"We finally got an ambulance right across the street here, we got two of the guys in, one guy ended up dying in my arms. My buddy got in there and we got three more people in the ambulance.
"I just got a message from my buddy and he's going to be OK".
Another witness told KSNV-TV that he heard "clip after clip after clip - bullets flying everywhere".
Fox News heard from a concert-goer, who said: "I heard what sounded like gunfire, and then people on stage started scrambling and everybody just kind of ran from that point.
"I stayed local in the concert venue, hid behind a little table, until everybody cleared and then I went out and there were a couple of bodies there and I started loading them into the back of a truck.
"One of them looked like she was probably dead, the other two, I'm not sure."
