Military Arrests Alleged Wikileaks SourceMilitary Arrests Alleged Wikileaks Source

The military has arrested a military intelligence analyst for allegedly leaking the video of a 2007 U.S. helicopter attack on people assembled in a Baghdad square that left two Reuters employees dead and two children wounded.

In a statement, the military said that it is holding Spc. Bradley Manning, 22, in Kuwait, pending an investigation of his leak of the classified video, which was made public by Wikileaks, a Web site that publishes anonymously submitted leaks of information. Manning is a member of the Army 2nd Brigade Combat Team, 10th Mountain Division, which is currently stationed in Iraq.

"The Department of Defense takes the management of classified information very seriously because it affects our national security, the lives of our soldiers, and our operations abroad," the military said in a statement. "The results of the investigation will be released upon completion of the investigation."

Former hacker and Wikileaks donor Adrian Lamo said on Facebook and Twitter that he "outed" Manning. "I've never turned anyone in before, and don't plan to again," Lamo wrote. "But he was like a kid playing with a loaded gun. Someone was bound to get hurt."

In a Tweet, Wikileaks said that Manning -- if confirmed as the whistleblower who provided the site with videos of controversial air strikes in Iraq and Afghanistan -- is a "without doubt a national hero."

In an initial story disclosing the arrest, Wired reported that Manning had told Lamo that he had sent Wikileaks a video of an airstrike in Afghanistan, an Army document that found Wikileaks to be a security threat, and 260,000 classified U.S. embassy cables. However, Wikileaks has since refuted that it possesses the classified cables, and called Lamo and Wired reporter (and former hacker) Kevin Poulsen "manipulators."

Among Wikileaks' revelations since launching in December 2006 have been: documents apparently showing corruption by Kenyan leaders, protocols of the U.S. Army operations at the Guantanamo Bay detention camp, documents pertaining to Scientology's rituals and beliefs, former vice presidential candidate Sarah Palin's personal e-mails, thousands of Congressional Research Service reports, and intercepts of pager messages from September 11, 2001.
