WASHINGTON (AP) — The Pentagon says the Army's mistaken shipments of live anthrax were more widespread than it initially reported.

In a statement issued Friday evening, the department says 24 laboratories in 11 states and two foreign countries — South Korea and Australia — are believed to have received suspect anthrax samples.

The broadening scope of the problem suggests more extensive flaws in procedures used by the Army's Dugway Proving Ground in Utah. The anthrax samples were supposed to be made fully inert before they were shipped. Deputy Defense Secretary Bob Work has ordered a comprehensive review of laboratory procedures associated with inactivating anthrax.

Dugway is located in a desolate stretch of the Utah desert. Chemical weapons have been tested there since the facility opened in 1942.

The Centers for Disease Control and Prevention says it is testing to see which anthrax samples were live. The first full set of findings isn't expected until next week.
