The shooting took place at the Route 91 Harvest Fesitval, during which the assailant, 64 year-old Stephen Paddock opened fire on a crowd watching the musician Jason Aldean from the 32nd floor of the Mandalay Bay Hotel, Las Vegas. At least fifty-nine people have since been confirmed as dead with a further 527 hospitalised with injuries. Paddock was later found dead by police.

It has since been released that Paddock had a total of seventeen weapons in his hotel room on the night in question.

The Islamic State has also claimed the attack as one of their own. However, the FBI have not been able to verify whether or not Paddock was in fact a member of the Islamic terrorist organisation.

It is currently being called the worst mass shooting in American history.
