DELMAR, Del. (AP) Officials say a flash fire at the Delaware International Speedway has injured a 74-year-old man.

The Delaware State Fire Marshal's Office said in a news release that the man was transported to the Bayview Medical Center in Baltimore, where he is being treated for second- and third-degree burns to 20 percent of his body.
