Anthrax found at CIA headquarters

A spokesman for the US Central Intelligence Agency has revealed that traces of anthrax have been found at the agency’s mail-handling building in its McLean, Virginia, headquarters.

The spokesman said the amount found is "medically insignificant" and not enough to cause pulmonary anthrax, the most deadly form of the disease.

He said the building has been closed as a precaution and several employees have been given antibiotics.
