Monday’s episode of “Dancing with the Stars” will open with a moment of silence as a tribute to the victims of the deadly mass shooting in Las Vegas, ABC has announced.

The start of “Dancing with The Stars” will also be delayed from 8 p.m. ET to 8:05. “World News Tonight” anchor David Muir will anchor a live, five-minute update from Las Vegas on the events surrounding the shooting. Muir will also host an hour-long edition of “World News Tonight” Monday to focus on the events in Las Vegas. “The Good Doctor” will air as originally scheduled from 10-11.

On Sunday night, a man opened fire from his room on the 32nd floor of the Mandalay Bay Hotel and Casino on the Vegas Strip with a high-powered assault rifle, targeting the Route 91 Harvest Music Festival nearby. At least 58 people have died and more than 500 were injured in what is now the deadliest mass shooting in U.S. history. Police subsequently identified 64-year old Stephen Paddock, a resident of nearby Mesquite, Nevada, as the shooter. S.W.A.T. officers breached Paddock’s room with explosives, though he appears to have killed himself before police entered the room. Police also said that at least 10 weapons were found in Paddock’s possession.

FBI agent Aaron Rouse, who oversees Las Vegas for the bureau, dismissed a claim by the Islamic State terror group that Paddock was one of its operatives. “We have determined to this point no connection with an international terrorist group,” Rouse said. “We will continue to work with our partners to ensure that this is factually, thoroughly and absolutely investigated.”

The shooting broke out at the end of a Jason Aldean set, with some witnesses reporting that they had heard possibly hundreds of shots and saw at least one officer down. Videos posted to Twitter show concertgoers sheltering in place as gunshots are heard ringing throughout the area.
