LAS VEGAS (Reuters) - A retiree armed with multiple assault rifles strafed an outdoor country music festival in Las Vegas from a high-rise hotel window on Sunday, slaughtering at least 59 people in the deadliest mass shooting in modern U.S. history before killing himself.
The barrage of gunfire from the 32nd-floor of the Mandalay Bay hotel into a crowd of 22,000 people came in extended bursts that lasted several minutes, sparking panic as throngs of music fans desperately cowered on the open ground, hemmed in by fellow concertgoers, while others at the edge tried to flee.
More than 525 people were injured - some by gunfire or shrapnel, some trampled - in the pandemonium adjacent to the Las Vegas Strip as police scrambled to locate the assailant.
Police identified the gunman as Stephen Paddock, 64, who lived in a retirement community in Mesquite, Nevada. They said they believed he acted alone and did not know why he attacked the crowd.
The Islamic State militant group claimed responsibility for the massacre, but U.S. officials said there was no evidence of that.
At least a dozen people were in critical condition at University Medical Center in Las Vegas, where all of the injured were taken, a spokeswoman said.
The preliminary death toll, which officials said could rise, surpassed last year’s massacre of 49 people at a gay nightclub in Orlando, Florida, by a gunman who pledged allegiance to Islamic State.
The dead in Las Vegas included a nurse, a government employee and an off-duty police officer.
Shocked survivors, some with blood on their clothing, wandered streets, where the flashing lights of the city’s gaudy casinos blended with those of emergency vehicles.
Police said Paddock had no criminal record. The gunman killed himself before police entered the hotel room from where he was firing, Clark County Sheriff Joseph Lombardo told reporters.
“We have no idea what his belief system was,” Lombardo said. “I can’t get into the mind of a psychopath.”
Federal officials said there was no evidence to link Paddock to militant organizations.
“We have determined to this point no connection with an international terrorist group,” Aaron Rouse, special agent in charge of the Federal Bureau of Investigation (FBI) field office in Las Vegas, told reporters.

“We advise caution on jumping to conclusions before the facts are in,” CIA spokesman Jonathan Liu said in an email.
Lombardo said there were 16 firearms in the room where Paddock killed himself, some with scopes and some that appeared to have been modified to convert them to fully automatic weapons.
Lombardo said the gunman apparently used a “device similar to a hammer” to smash the windows from which he fired.
Police found at least 18 additional firearms, some explosives and thousands of rounds of ammunition at Paddock’s home in Mesquite, about 90 miles (145 km) northeast of Las Vegas, along with “some electronic devices that we are evaluating at this time,” Lombardo told reporters.
Chris Sullivan, the owner of the Guns & Guitars gun shop in Mesquite, issued a statement confirming that Paddock was a customer who cleared “all necessary background checks and procedures.”
“He never gave any indication or reason to believe he was unstable or unfit at any time,” Sullivan said, adding that his business was cooperating with investigators. He did not say how many or the kinds of weapons Paddock purchased there.
The shooting, the latest in a string that have played out across the United States over recent years, sparked a renewed outcry from some lawmakers about the pervasiveness of guns in the United States, but was unlikely to prompt action in Congress.
Efforts to pass tougher federal gun laws failed following a number of mass shootings, including the 2012 massacre of 26 young children and educators in Newtown, Connecticut, and the June attack on Republican lawmakers practicing for a charity baseball game.
Nevada has some of the nation’s most permissive gun laws. It does not require firearm owners to obtain licenses or register their guns.
House of Representatives Minority Leader Nancy Pelosi, a Democrat, on Monday called on House Speaker Paul Ryan to create a select committee on gun violence.
“Congress has a moral duty to address this horrific and heartbreaking epidemic,” Pelosi wrote.
The Second Amendment of the U.S. Constitution protects the right to bear arms, and gun-rights advocates staunchly defend it. U.S. President Donald Trump, a Republican, has been outspoken in his support for the Second Amendment.
The White House said on Monday that it was too soon after the attack to consider gun control policies.
“Today is a day for consoling the survivors and mourning those we lost,” presidential spokeswoman Sarah Sanders said at a news briefing. “It would be premature for us to discuss policy when we don’t fully know all the facts or what took place last night.”
Trump said he would travel to Las Vegas on Wednesday to meet with victims, relatives and first responders.
“It was an act of pure evil,” said Trump, who later led a moment of silence at the White House in honor of the victims.
The suspected shooter’s brother, Eric Paddock, said the family was stunned by the news.
“We’re horrified. We’re bewildered, and our condolences go out to the victims,” Eric Paddock said in a telephone interview, his voice trembling. “We have no idea in the world.”
He said his brother belonged to no political or religious organizations, and had no history of mental illness. Their father had been a bank robber who for a time was listed on the FBI’s “Ten Most Wanted” list of fugitives.
Speaking to reporters from his doorstep in Orlando, Florida, he described his brother as “a wealthy guy” who liked to play video poker and take cruises. He seemed to have been settling into a quiet life when he moved back to Nevada from Florida.
Video of the attack showed terrified crowds fleeing under rapid gunfire as the shooter took aim from a distance of around 1,050 feet (320 m).
“People were just dropping to the ground. It just kept going on,” said Steve Smith, a 45-year-old visitor from Phoenix, Arizona.
Las Vegas’s casinos, nightclubs and shopping draw some 3.5 million visitors from around the world each year and the area was packed with visitors when the shooting started shortly after 10 p.m. local time (0400 GMT).
Mike McGarry, a financial adviser from Philadelphia, was at the concert when he heard hundreds of shots.
“It was crazy - I laid on top of the kids. They’re 20. I‘m 53. I lived a good life,” McGarry said.
The back of his shirt bore footmarks from people who ran over him in panic.
Shares of MGM Resorts International, which owns the Mandalay Bay, fell 5.58 percent on Monday to $30.77 a share.
