At least 59 people have died and well over 500 more were injured.

“Out of respect to the victims of last Sunday’s terrible tragedy in Las Vegas, and their families, The CW Network and iHeartMedia will be postponing this week’s TV broadcast of the iHeartRadio Music Festival,” the network said in a statement (via Deadline). “New broadcast dates will be announced at a later time.”
