Las Vegas death toll reaches 50

At least 50 people have been killed and another 200 have been wounded in a mass shooting at a Las Vegas concert.

A gunman, named as 64-year-old local resident Stephen Paddock, opened fire from the 32nd floor of the Mandalay Bay Hotel towards an open-air music festival. He was shot dead by officers in the hotel where a number of guns were found.

Sheriff Joe Lombardo described the shooting as a "lone wolf" attack. He added that police were now confident they had located a woman, earlier named as Marilou Danley, who was suspected of travelling with the gunman before the attack, BBC reported.

The attack is the worst mass shooting in recent US history.
