A group of survivors of the Route 91 Harvest Festival massacre marked the anniversary of the shooting by staging a prayer vigil before Jason Aldean's set in California on Saturday night.

Almost 60 country fans lost their lives during Aldean's headlining set at the festival in Las Vegas on October 1, 2017, when a gunman opened fire on the crowd.

A group of survivors made the trip to the singer's Irvine show and prayed together before his set.

A remembrance concert was also held in Las Vegas on Saturday to honor the victims of the shooting. Survivors and friends and family gathered to pay tribute to those who were killed.

More tributes are expected throughout Monday as survivors and the friends and family of the deceased mark the date anniversary of the tragedy.
