Rail cars carrying hazardous material derailed and burst into flames Friday in a remote area of North Dakota, but officials said no one was hurt and the threat to those living nearby appeared to be minimal.

Twenty-nine cars of a CPKC train derailed around 3:45 a.m. in an area surrounded by farmland that’s about 140 miles (225 kilometers) northwest of Fargo, said Andrew Kirking, emergency management director for Foster County.
