BOSTON, Massachusetts (AP) -- Bomb units scrambled Wednesday afternoon to investigate four suspicious devices reported to police almost simultaneously throughout Boston.

The reports forced the temporary shutdowns of part of an interstate, a key inbound roadway and a bridge between Boston and Cambridge.

Police said four calls, which all came in around 1 p.m., reported suspicious devices at the Boston University Bridge, the Longfellow Bridge, the Tufts-New England Medical Center and a major intersection.
