A whistleblower website has published what it says are more than 90,000 United States military and diplomatic reports about Afghanistan filed between 2004 and January of this year.
The first-hand accounts are the military's own raw data on the war, including numbers killed, casualties, threat reports and the like, according to Julian Assange, the founder of WikiLeaks.org, which published the material Sunday.
"It is the total history of the Afghan war from 2004 to 2010, with some important exceptions - U.S. Special Forces, CIA activity, and most of the activity of other non-U.S. groups," Assange said.
CNN has not independently confirmed the authenticity of the documents.
The Department of Defense will not comment on them until the Pentagon has had a chance to look at them, a Defense official told CNN.
National Security Adviser Gen. James Jones issued a statement Sunday calling the documents' release "irresponsible."
"The United States strongly condemns the disclosure of classified information by individuals and organizations which could put the lives of Americans and our partners at risk, and threaten our national security," the statement said.
