Thousands of country music fans fled in terror on Sunday as at least 59 were killed when bullets rained down on a concert in Las Vegas.

But many stood to face the terror head-on, including one man filmed opening his arms and shouting 'come on p******' as gunfire crackled around him.

Several others were filmed staying on their feet, including one man who gave the finger before taking a sip of his beer.

This is the moment one concert-goer in Las Vegas stood up and yelled while automatic gunfire crackled around him as Stephen Paddock carried out the worst mass shooting in US history

The man was heard shouting 'come on you p******' as everyone else ducked down or ran for their lives from the massacre

Police say at least 59 are dead and 527 were wounded during the attack which took place at the Route 91 Harvest Festival on Sunday

The focus of their anger was Stephen Paddock, 64, from Nevada, who was identified by police as the man who carried out the massacre shortly after 10pm.

Officers say Paddock fired on the Route 91 Harvest Festival from the 32nd floor of the Mandalay Bay hotel where he had been staying for days as he planned the atrocity.

He shot himself dead as officers surrounded a room where he had amassed an 'arsenal' of at least 10 rifles.

Before killing himself, Paddock engaged police in a firefight leaving one in critical condition, later downgraded to stable after surgery, and another with minor injuries.

Investigators have raided Paddock's $400,000 home, located in a nearby retirement community, but say they have no word on his motive.

ISIS has claimed responsibility for the attack, saying Paddock converted to Islam months ago, but the FBI has since said there is no indication he was part of any foreign terror group.

Witnesses described seeing off-duty service personnel and police officers plugging bullet wounds with their fingers after the attack.

Another country music fan was pictured giving the finger and then sipping his beer during a lull in the shooting while Paddock stopped to reload

Russell Bleck said that while concert-goers hit the floor, police stood tall in order to direct people to safety, risking their lives to save others.

Other videos showed thousands of people fleeing in terror while others sheltered behind whatever cover they could find.

The wounded were rushed to safety using office chairs, wheelbarrows, or were simply slung over people's shoulders as the chaos unfolded.

President Trump has given an address to the nation following the attack, calling it 'an act of pure evil'.

'Scripture teaches us, "The Lord is close to the brokenhearted and saves those who are crushed in spirit,"' Trump said. 'We seek comfort in those words but we know that God lives in the hearts of those who grieve.'

Trump also announced that he would travel to Las Vegas on Wednesday.

Meanwhile Eric Paddock, Stephen's brother, said there was 'absolutely no indication' that he was about to do something like this.

He said: 'He was just a guy. Something happened, he snapped or something'.

Speaking from his home in Orlando, Florida, Eric said: 'We know absolutely nothing, this is just, we are dumbfounded.

'We have absolutely no idea. Our condolences go to the victims and all their families'.

He added that his brother had 'no political affiliation, no religious affiliation, as far as we know' and that he'd never been 'an avid gun guy at all', adding that he was at a loss as to where Stephen got his arsenal of automatic weapons from.

'He has no military background,' he added to CBS News.
