Bradley Manning, the soldier accused of the biggest unauthorised disclosure of state secrets in US history, has pleaded guilty to being the source of the leak, telling a military court that he passed the information to a whistleblowing website because he believed the American people had a right to know the "true costs of war".
At a pre-trial hearing on a Maryland military base, Manning, 25, who faces spending the rest of his life in military custody, read out a 35-page statement in which he gave an impassioned account of his motives for transmitting classified documents and videos he had obtained while working as an intelligence analyst outside Baghdad.
Manning said: "We were obsessed with capturing and killing human targets on lists and ignoring goals and missions. I believed if the public, particularly the American public, could see this it could spark a debate on the military and our foreign policy in general [that] might cause society to reconsider the need to engage in counter-terrorism while ignoring the human situation of the people we engaged with every day."
