Pentagon's plea to website

The Pentagon has asked a website that solicits leaked government secrets to cancel any plan to publish more classified military documents and pull back tens of thousands of secret Afghan war logs already posted on the internet.

The demand, which the Pentagon has no independent power to enforce, is primarily aimed at preventing release of approximately 15,000 secret documents that the website WikiLeaks has said it is holding.

The Pentagon also hopes to stop WikiLeaks from making public the contents of a mammoth encrypted file recently added to the site.

Contents of that file remain a mystery.

WikiLeaks posted more than 76,900 classified military and other documents, mostly raw intelligence reports from Afghanistan, on its website on July 25.
