Thousands of country music fans became witnesses or victims of the deadliest mass shooting in modern US history when a gunman unleashed "hundreds" of bullets into the Las Vegas Strip crowd.
At least 59 people were killed, Las Vegas Sheriff Joseph Lombardo said. A hailstorm of bullets and the subsequent stampede left more than 527 people injured, officials said. The crowd was watching a concert by country music superstar Jason Aldean.
The gunman, 64-year-old Stephen Paddock, was firing from the 32nd floor of the nearby Mandalay Bay hotel, Lombardo said. Paddock was eventually killed by police.
