WRC-TV reporter Tom Sherwood reports that all D.C. government mailrooms have been temporarily shut down as a result of two packages which detonated at Maryland state buildings in Anne Arundel County this afternoon. Sherwood notes that the move is “precautionary only.” Earlier today, two U.S. Post Office packages experienced “flareups” after being opened at a Maryland Department of Transportation building near Baltimore-Washington International Airport and at the Jeffrey Building in Annapolis. All Maryland government mailrooms were also locked down shortly after the incidents.
