A day after tragedy struck Las Vegas while he was performing on stage, Jason Aldean issued a second response to the horrific events of Sunday night.

"Over the last 24 hrs I have gone through lots of emotions," the singer began in a lengthy post to his Instagram account late Monday. "Scared, Anger, Heartache, Compassion and many others. I truely dont understand why a person would want to take the life of another." [sic]

The country star was headlining the Route 91 Harvest country music festival when a gunman, now known to be Stephen Paddock, opened fire on the 22,000 concertgoers below from the nearby Mandalay Bay Hotel and Casino. At least 59 people have been killed, another 527 wounded, after frantic concertgoers screamed and ran for their lives, marking the deadliest mass shooting in modern U.S. history. Las Vegas hospitals are swamped with victims as local Americans flock to donate blood and participate in nearby vigils for the victims.

"Something has changed in this country and in this world lately that is scary to see," Aldean continued. "This world is becoming the kind of place i am afraid to raise my children in. At the end of the day we arent Democrats or Republicans, Whites or Blacks, Men or Women. We are all humans and we are all Americans and its time to start acting like it and stand together as ONE!" [sic]

He added, "That is the only way we will ever get this Country to be better than it has ever been, but we have a long way to go and we have to start now."

Aldean echoed the feelings of many Americans, saying his heart aches for the victims and their families after the senseless act. "I am so sorry for the hurt and pain everyone is feeling right now and there are no words i can say to take that pain away," he wrote. "Just know u all are in my heart and my prayers as we all go through this together. Time to come together and stop the hate!"

The singer first took to Instagram shortly after the late-night attack Sunday to announce that he was safe and ask people to pray for Las Vegas.

President Donald Trump called the tragedy an "act of pure evil" and stressed unity from Americans in a Monday address. On Tuesday, while heading to the hurricane-ravaged Puerto Rico, Trump told reporters, "We'll be talking about gun laws as time goes by."
