Pentagon, State Secrets | featured news

A former Navy SEAL's insider account of the raid that killed Osama bin Laden contains classified information, the Pentagon said Tuesday, and the admiral who heads the Naval Special Warfare Command said details in the book may provide enemies with dangerous insight into secretive U.S. operations.

In the wake of WikiLeaks' release of more than 250000 classified US diplomatic cables, the Pentagon is reportedly taking measures to prevent this type of breach from happening again.

The Pentagon has burned 9,500 copies of Army Reserve Lt. Col. Anthony Shaffer's memoir "Operation Dark Heart," his book about going undercover in Afghanistan.

A Department of Defense official tells Fox News that the department purchased copies of the first printing because they contained information which could cause damage to national security.
