The whistleblower website WikiLeaks released a cache of more than 700 classified U.S. military documents on Monday containing details about detainees being held at Cuba's Guantanamo Bay prison.

The files, which have been made available to U.S. and European news outlets, provide assessments of all 780 terror suspects who've passed through the detention facility, including alleged 9/11 mastermind Khalid Sheikh Mohammed.

According to the files, Mohammed vowed to unleash a "nuclear hellstorm" if Osama Bin Laden was ever captured or assassinated.

The release of the documents drew strong words of condemnation from the White House.

"Both administrations have made the protection of American citizens the top priority," the White House said, "and we are concerned that the disclosure of these documents could be damaging to those efforts."

So far, 604 detainees have been transferred out of Guantanamo while 172 remain.
