Holy Cross Hospital is now treating five D.C. postal workers for possible inhalation anthrax. The hospital says twomore people with flu-like symptoms were admitted overnight. Two postal workers, Joseph Curseen and Thomas Morris,died of what officials say was inhalation anthrax on Monday.

Federal investigators still have no firm idea who is sending envelopes of the deadly microbe through the mail or whatis motivating the attacks, according to lawmakers, public health experts and law enforcement officials.

Meanwhile the Pentagon has approved the development of a genetically modified “super-anthrax” bacteria to test USdefenses against biological attack, overriding concerns that the research could violate a 1972 germ warfare treaty.
