At least 58 people have been killed and another 515 injured in Las Vegas in what is now the deadliest mass shooting in modern US history.

A gunman, named as 64-year-old Stephen Paddock, opened fire from the 32nd floor of the Mandalay Bay Hotel, spraying bullets at the crowd watching a music festival on the Las Vegas strip.

The attack is deadlier than the shooting at the Pulse nightclub in Orlando in June 2016, which left 49 dead.

As more details emerge, the shooting is likely to reignite the debate on gun control in the US, with #guncontrolnow already trending on Twitter.

Our grief isn't enough. We can and must put politics aside, stand up to the NRA, and work together to try to stop this from happening again. — Hillary Clinton (@HillaryClinton) October 2, 2017





Barack Obama consistently fought with the US senate to bring in meaningful gun control in the country, saying the US “could not wait” after a series of deadly attacks.

However, Donald Trump, his successor, was endorsed by the National Rifle Association and is opposed to restricting the sale of assault weapons.

The Las Vegas attack is the 338th mass shooting of 2017 — after just 273 days — according to a website that monitors gun deaths.
