Las Vegas shooting: Stephen Paddock set up cameras around hotel room while girlfriend is 'person of interest' - as it happened

Terrifying video footage has emerged of the moment Las Vegas gunman Stephen Paddock opened fire on crowds at a country music festival: 

House speaker Paul Ryan said there were no plans for the House to act soon on a National Rifle Association-backed bill to ease regulations on gun silencers.

A House panel had backed the bill last month and lawmakers were expected to move ahead on the measure. 

The bill is "not scheduled right now. I don't know when it will be scheduled," Ryan said, after issuing a call for unity and peace in the wake of Sunday's shooting. 

Hospital officials said at least 45 people remain in critical condition after being wounded in the mass shooting at a Las Vegas music festival on Sunday. 

Sunrise Hospital has 33 people and University Medical Center has 12 people still in critical condition. 

At Sunrise, a total of 68 people remain hospitalised out of the 214 initially admitted. Officials say 15 people have died there. 

Officials say a total of 60 people remain hospitalised out of the 104 who were taken to University Medical. Four have died. 

The death toll has remained at 59 since Monday.

Las Vegas shooting witnesses speak about the panic that ensued as crowds tried to escape the barrage of gunfire:

- Isis still maintain Paddock acted for the group but this has been repeatedly refuted by the FBI

- The gunman was able to unleash hundreds of rounds of gunfire on a crowd of concertgoers with two "bump-stocks" that may have converted semi-automatic firearms into fully automatic ones, officials said

- National Rifle Association has still not broken its silence, one day on from the worst gun massacre in US history

- US citizens living near scenes of mass public shootings are more likely to prefer stricter gun control, according to new research

- Steve Bannon has warned the President his core supporters would react in horror if he were to back any move to restrict access to firearms

The Associated Press has spoken to one of the medical staff that treated victims of the Las Vegas shooting:

In cars, in ambulances waiting four or five deep, from the walking wounded to the barely alive, they arrived in droves. 

"I have no idea who I operated on," said Dr Jay Coates, a trauma surgeon whose hospital took in many of the wounded. "They were coming in so fast, we were taking care of bodies. We were just trying to keep people from dying." 

University Medical Center of Southern Nevada was one of many hospitals that were overflowing. 

"Every bed was full," Dr Coates said. "We had people in the hallways, people outside and more people coming in." 

Hospital officials say that at least 45 people remain in critical condition after being wounded during the mass shooting.

Sunrise Hospital has 33 people in critical condition, while University Medical Center has 12 people still in critical condition as of Tuesday morning. 

Anonymous law enforcement officials have told NBC News and CNN that the Las Vegas shooter Stephen Paddock, wired $100,000 to an account in the Philippines at some point before Sunday’s shooting.

According to NBC, Paddock wired the money to an account there in the week before the shooting. His girlfriend, Marilou Danley, was born in the Philippines and was abroad at the time of the shooting.

The University Medical Centre of Southern Nevada says that it took in 104 people in the hours after the bloody shooting in Las Vegas, creating a grim scene that one doctor previously said looked like a war zone.

The hospital is the main critical trauma facility in southern Nevada, and said in a statement that it admitted more than 20 people in critical condition. Many still need breathing tubes.

Many gunshot victims didn't need surgery, the hospital said.
