A printed matter with suspicious white powder came to the Express-Volga bank in Saratov on Thursday (Saratov is a regional centre in the Volga region). The mail was sent from the US and addressed to a bank staffer. A polyethylene packet with white substance was discovered when the parcel was unwrapped. The Emergency Ministry's experts who arrived at the scene sent the find for examination. The Saratov epidemiological station began the tests on Friday morning. Its results will be known in several days.
