Witnesses recalled the terrifying moments before the explosion and in its aftermath. “I’ve never seen anything like it,” resident Betsy Williams told CNN. “It shook everything.”

She said she heard the warning from what sounded like an automated female voice. She said if the gunshots hadn’t woken her up, she’s not sure she would have heard the message.
