At least 50 people were killed Sunday night after a gunman opened fire on the Route 91 Harvest Festival in Las Vegas. The gunman started shooting from across the street on the 32nd floor of the Mandalay Bay Hotel and Casino; he died in the hotel room after officers used explosives to get inside.
Country star Jason Aldean was on stage when the gunfire started; he stopped playing and the crowd grew quiet as everyone tried to make sense of what happened. As more shots rang out, victims fell to the ground, others hid, and some others tried to flee; Aldean quickly ran off stage. The incident was the deadliest mass shooting in U.S history.
Aldean posted an Instagram with the words "Pray for Las Vegas" in response to the attack, and let his fans know he and his crew were safe. "Tonight has been beyond horrific," he wrote. "It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night."

Jake Owen, who was also on stage at the time, tweeted that he "witnessed the most unimaginable event tonight."
