About a 100 postal workers were evacuated from the facility while hazardous material crews conducted tests on the white substance that was initially speculated to be a biotoxic substance. Officials say that one of the parcels of mail involved was addressed to the U.S. State Department. REUTERS/Anthony P. Bolante APB
