A "Bulgarian" connection?

[NYC, Brooklyn] Police stumbled upon a bomb-making factory Sunday in the home of a Columbia professor who specializes in the spread of infectious disease [including AIDS] - and are investigating whether he and his roommate [Ivaylo Ivanov] have terror ties. Cops evacuated the Brooklyn Heights neighborhood around the Remsen St. home of Michael Clatts, a medical anthropologist, after finding seven pipe bombs fitted with fuses in his flat, police sources said.  The frightening cache was discovered almost by accident - Ivaylo Ivanov, the man living with Clatts, accidentally shot off the tip of his left index finger and sought police help in the street about 1:15 a.m.
