WikiLeaks founder Julian Assange gave a wide ranging interview with the Australian television program 7.30 on Sunday, during which he contradicted a quote attributed to him by British newspaper The Guardian.

The paper had claimed he'd said that some informants deserve to die.

Asked if this was truly his view, Assange replied: "No, and we are suing them for libel. We have witnesses to show that is a libellous claim, and is an ongoing dispute, so there's a lot of vitriol in the top end of the news business and a lot of back-stabbing, and unfortunately we happen to be on the receiving end of it from this individual."

Asked a second time, he simply said the quote was "fabricated."

The WikiLeaks founder also worried about danger from "mentally unstable people" who were inflamed by comments made by many American public figures, such as Sarah Palin, calling him a terrorist who should be dealt with by any means necessary.

"We have bills in the US Senate to declare our organisation a transnational threat, to take us from the status of individuals, Australians, Americans, and turn us into enemy combatants, where we can be dealt with in the same manner as senior figures in the Taliban or Al Qaeda," he said. "That’s serious business."
