• A general fighting with the Northern Alliance to rid his country of the ruling Taliban said today his forces spent the last week with American military officials.

The Anthrax Scare:

•  A New York Post employee tested positive for anthrax but is recovering well and has returned to work. The source of the anthrax hasn't been identified. More tests are being done at the newspaper's Manhattan offices.
