Before the midnight hour on Sunday an explosion of shots rang out from apparent machine gun fire after at least one gunman opened fire on a Las Vegas festival where Jason Aldean was performing. ET confirmed that the country star and his team are safe following the incident.

The shots may have come from the top floors of nearby Mandalay Bay Hotel and Casino, at which time fans attending the Harvest Country Route 91 Music Festival scattered, trying desperately to find cover. Some reportedly lay on the ground.
