Wikileaks is now planning to release another 15,000 documents about the war in Afghanistan.
The files were held back in July because of their sensitive content but have now been fully vetted for release. The website insists their contents cannot harm individuals.
Pentagon spokesman Marine Corps Colonel Dave Lapan said: 'We deplore WikiLeaks for inducing individuals to break the law, leak classified documents and then cavalierly share that secret information with the world, including our enemies.
'We know terrorist organisations have been mining the leaked Afghan documents for information to use against us, and this Iraq leak is more than four times as large.
'The only responsible course of action for WikiLeaks at this point is to return the stolen material and expunge it from their websites as soon as possible.'
WikiLeaks says it has deleted names that might result in reprisals.
