CIA: Wikileaks sharing 'inevitable'

Former director of the CIA General Michael Hayden has told the BBC that the shift to sharing intelligence after the 11 September attacks made a leak of tens of thousands of secret US military documents "inevitable" - and it could happen again.

The website Wikileaks published the documents a fortnight ago, but in a special report, the BBC's Nick Childs was told it could have 750,000 other classified documents it has not yet published.
