(CNN) -- More than 250,000 secret U.S. diplomatic cables are now available in full and unfiltered online, exposing scores of U.S. diplomatic sources and informants that were meant to be protected often for their own safety, according to the website WikiLeaks. But this is not an official WikiLeaks release. Rather, what appears to be a string of errors has lead to both the raw file and the password that unlocks that file to be released into the public domain, without WikiLeaks control. In a statement posted on Twitter, WikiLeaks said, "Guardian investigations editor, David Leigh, recklessly, and without gaining our approval, knowingly disclosed the decryption passwords in a book published by the Guardian."
