RANSON, W.Va. -- A West Virginia post office has been evacuated after a package exploded and firefighters said a white powder escaped.

The Independent Fire Company in the small town of Ranson told the Hagerstown Herald-Mail that the explosion occurred at about 7:45 a.m. Friday at the Ranson Post Office.

Neither Jefferson County emergency services nor State Police would immediately comment. Ranson is in a rural area in the state's Eastern Panhandle.

Postmaster Steve Parrill told The Associated Press that employees were evacuated and State Police were on scene.

Parrill wouldn't provide details on what happened but said about 20 people work in his branch.
